In collaboration with Cardioline Spa, this graduation project presents the development of a discreet device to monitor atrial fibrillation among elderly people. By means of user research and contest analysis, the project is aims at delivering a new product-system device for the company, for Healthcare institutions and for private patients. The project is characterized by three main phases: the first one is about the analysis of the holter monitor world ; the second is related to synthesizing the research results into one concept; and the third one focuses on validating and test the concept proposed. According to the three pillar of Industrial design engineering the research was divided into the three macro areas of: People, Business and Technology. The people linked with the holter monitor system investigated during several activities including Interviews were 14 elderly patients, one General practitioner, one cardiologist and two nurses. Furthermore, to dive deeper into the experience I underwent a 24 hour holter monitor experience. The magnitude of the cardio healthcare business side was explored by the analysis of the main Healthcare trends. In addition, special attention was given to Cardioline’s past innovations and some guidelines for future innovations were outlined. The technology side was also investigated. The Scope of the technology analysis was to understand the current state of the art of ECG technology and its related evolution over the years. There was a special focus on the transition from the current situation to the mobile health and to why biosensors are preferred to the standard holter monitor. To close the technological part, a perceptual map was made in order to compare the Cardioline product with its competitors. The perceptual map was also used to decide on the transition from the current product to the future product. All the data collected during the analysis phase was collected in a list of requirements composed of demands (hard requirements) and wishes (soft requirements). Afterwards a brainstorm session was run taking into account some of the main problem revealed. After several iterations, the brainstorm results were synthesized into three concepts which were presented during the midterm presentation. Feedback was provided by chair, by mentor and by the Company mentor. Suggestions were used to determined the final user scenario, the final system layout and the final concept. The final concept consisted of a wearable device which records and transmits ECG signal to the smart phone. The smart phone collects and transmits data to the cloud server where the user and Doctor, if authorized, can have access. With a special focus on the setting up phase, a test was performed. The scope of the test was to check if specific concept features were correctly driving the user towards the hypothesised behaviour. The test revealed good and improvable aspects of the product-system designed. The improvable aspects were used to refine the final concepts. Finally, together with Cardioline supervision, several engineering ecommendations were elaborated. Those recommendations were related to the concept material, to the electronic components

It is time to break the taboo on something that every person does every day: excretion. Using the toilet for micturition and defecation is familiar to everyone. However, discussing personal troubles with going to the toilet is frowned upon. Constipation complaints and urine retention are common, especially among the elderly. There are multiple ways of countering these complaints, with this report focusing on taking the right body posture while sitting on the toilet. This posture consists of raising the knees above hip height, aiming for more pelvic floor muscle relaxation.This report explores a new product design that helps people to fight constipation and urine retention complaints, by assisting them to get an ergonomically beneficial toilet posture. First, the current scenario of this problem and its environment was explored thoroughly, in order to create the full relevant picture. Information was gathered from the target group, medical professionals from ErasmusMC Rotterdam (i.a. urologists and pelvic floor therapists), nursing home staff and other IDE experts. Existing solutions are not fulfilling, or even dangerous, especially for elderly users. Therefore, the target group in this project is focused on the elderly. Through solving sub problems, researching technical possibilities and pinpointing wishes and demands, possible design directions were explored. Eventually, the EasyRaise was chosen as the proposed concept that aimed to solve the problems best. The EasyRaise consists of a platform that effortlessly lifts the legs of the user upwards to the user’s personal perfect height. The user operates the platform by him-/herself with a wireless remote and is informed by a medical expert on the desired optimal height of the platform. Hand support can be included to help the user get on and off the platform and provide help with standing up and balancing. The remote can be stored on the hand support extension. The proposed concept of the EasyRaise went through three types of evaluation. A physical prototype was created to test the working of the lift mechanism. Target group participants were asked to assess the functionalities and desirability of the concept. Finally, ErasmusMC staff were invited to share their medical insights on the EasyRaise, and whether they would recommend it. The EasyRaise leads to increased quality of life and decreased health costs, as autonomy is enhanced and medicines like laxatives are diminished. The report is concluded with a set of recommendations and conclusions that elaborate on the steps needed to take this concept to the next development stage.

This is a 5-month master graduation project in collaboration with Praxa Sense to design the next generation Atrial Fibrillation diagnosis device. A long-term (more than one month) continuous, off-hospital diagnosis device is designed with the focus on user experience and diagnosis accuracy. There are several phases in this project including research and analysis, defining the scope, synthesis and design, and evaluation. Desktop research and interviews were carried out during the research phase, which helped to define the scope of this wicked problem. Then synthesis and design cover the ideation, concretization and detailed design of the final product, in which various design methods were applied. Evaluation includes different user test of the product.The result is the most compact and comfortable Atrial Fibrillation diagnosis device in the market with medical grade diagnosis.

Bicycle helmets reduce the chance of certain injuries such as skull fractures according to various research. However, they are not designed to prevent other injuries such as concussions or traumatic brain injury. This is due to test regulations, which only test for high speed linear accelerations. In reality however, low speed as well as oblique impacts occur frequently. A design is proposed that adds an extra layer to the inside of the modern helmet. Four zones with impact absorbing cylinders are both able to absorb low speed linear accelerations by compression, as wells as angular accelerations (as a result of oblique impacts) by shearing.

The human body, although seemingly symmetrical, can in fact be highly asymmetrical. Our bodies are predetermined by our DNA and co-shaped by our environment. This leads to most of the world's population having a discrepancy in leg length either from birth or developed during their life time. It is completely natural and goes unnoticed, as changes are incremental and people get used to it. On the contrary, when undergoing total hip replacement surgery and waking up with one leg longer than the other, the change is almost instantaneous and immediately noticeable. Current surgical solutions do not address this issue in a practical manner within the operating theatre, leading to surgical teams developing their own methods and procedures to evaluate the change in patient's leg length.   Introducing new workflows to medical professionals often entails neglecting the protocols they spent years practicing. This thesis identified this bottleneck and instead of introducing new methods and procedures, it was decided to build on existing ones. This was done by exploring common surgical workflows in respect to total hip replacement and determining an approach to enhance surgical team's capabilities in evaluating leg length discrepancy.. Important in achieving this goal it to make any given design solution effortless, reliable and undisruptive to various workflows In order to do so, user research was performed by joining multiple surgical teams within the OR, thereby observing and evaluating their methods. One method in particular stood out, which is best described as the 'loaded assessment'. During this assessment the surgeon or circulating nurse will centre the patient's feet, apply pressure to the heels and try to evaluate the discrepancy. Although this method being seemingly simple, its execution is difficult to perform by a single person and varying pressure differences may confuse the assessment. Following the initial research phase, co-creation sessions with technical experts were organised, after which various concepts were developed and tested on the basis of feasibility, desirability and viability. Finally, a functional prototype based on the loaded assessment principle was developed and tested for its functionality and conceptual expectation.

Support people, especially support the bereaved people, is a challenging task. People’s attitudes towards death vary because many factors can influence it, such as gender, age, educational background, cultural and religious factors. The personality of the attitudes towards death stops people from supporting the bereaved actively because they are aware that their unprofessional actions may cause secondary injury and offend. Similarly, it makes it difficult for the bereaved to express their needs because of the sensitivity of the death. In most situations, due to the concerns listed above, supporting the bereaved to cope healthily is considered as a task that should be better conducted by formal support, such as support provided by psychologists and social workers. However, it is proved that informal social support is also necessary for healthy grieving. This project explores the opportunity of promoting informal social support in the working context. In detail, it focuses on supporting the bereaved to have a healthy grieving by facilitating the support provided by their colleagues. Based on the “Network of care” theory, this project defines all stakeholders in three groups: The bereaved, the colleagues, and the facilitator. This project explores the barriers that stop the colleagues from supporting the bereaved and studies the possibility for the facilitator to facilitate a support strategy. Choosing IDE faculty as the project context, this project ends up with a feasible service supported ritual that can reduce the unaware concerns related to death, raise the awareness of supporting each other, and build the connection between the bereaved and their colleagues, concern-free and caring.

Working on the rail infrastructure is physically tough. Heavy tools are lifted and carried while in unfavourable postures and in a harsh environment. An integrated design of tool carrier and working process eliminates the toughest of the loads imposed on the body of railway workers.

The project that is performed is for the master thesis of the master study ‘Integrated Product Design’ at the faculty of Industrial Design Engineering at the TU Delft. The final product is a handbook that functions as a tool to create a dock for SeaBubbles, and it is developed for the company Advier. The process started with exploring the scope. The scope can be split up in three directions: the business direction in which the company Advier and its stakeholders is analysed. It becomes clear that Advier will give the handbook to a design agency that will create the actual dock design. The second direction is the analysis of the location. The network is situated in the area of Dordrecht, also known as Drechtsteden. The effect of the weather and tide on this area is analysed and the conclusion is drawn that the design of the dock must deal with changing water levels. The third direction focuses on the SeaBubble, in which the SeaBubble for seven passengers and twelve passengers are presented. The reservation system is mapped out and shows that the SeaBubble will define its route on the demand, in between it is possible that the SeaBubble will change its route. This has a large impact on the passenger journey. In the passenger journey, two types of passengers are presented: a prepared and an unprepared passenger. The prepared passenger has bought a ticket at home, while the unprepared passenger must buy a ticket at the dock. From this point in the process, the focus will be on the experience of the passenger. By creating a building that fulfils the needs of the passenger when the passenger is being guided, is waiting, and is boarding, the experience of the passenger will be good. The next part that is being analysed is the elements that is needed for guiding, waiting and boarding. For guiding, first the crowd flow is analysed. Based on this crowd flow, a general layout of the building is created for the location of ticket vending machines, waiting areas and potential one-way systems. Secondly, the needed information is analysed and tested in an online 3D environment. The location and the initial way of communication for several information elements is determined. For waiting, literature is analysed, and people are interviewed and observed. The passengers will find distraction on a smartphone or while enjoying the view, having a seat is preferred. For creating a comfortable boarding experience, two supports are needed in an area with even floor and no gaps. By getting inspired from the results, different configurations of docks were created. By determining the principles behind the configurations, the design choices are mapped out. These design choices are structured with a morphological map and explained in the handbook, which is the final product of this master thesis. After finalising the handbook, interviews were held with the client and an architect to evaluate the final product.

Hyperthermia is a clinical cancer treatment method that relies on the principle of selectively heating tumour tissue with temperatures between 40 - 44 °C. For most head- and neck tumours deep hyperthermia treatment (DHT) is applied, in which electromagnetic energy is emitted to tumour tissue located ≥ 4cm below the skin surface. At the Erasmus MC Cancer Institute in Rotterdam, The Netherlands, electromagnetic energy is applied from a circular shaped applicator that is placed around the patient’s head or neck. A water bolus is placed between the applicator and the patient’s skin to act as a cooling agent to prevent skin burns and as a transferring agent to conduct the electromagnetic energy to the internal tumour tissue. The goal of this master thesis was to redesign the water bolus that is currently applied in DHT at the Erasmus MC to increase patient- and operator comfort. For this purpose two main design challenges were addressed: i) Design of an ergonomic fit for the water bolus ii) Development of a method for uniform skin cooling and pressure control For an optimal ergonomic fit of the water bolus, a 4D anthropometric model of head and neck was developed based on the 3D images of head and neck cancer patients that are treated at the Erasmus MC. Additionally, to secure appropriate cooling and pressure a honeycomb grid was developed. The pattern of the cavities in the grid guides circulating water through the entire volume to uniformly cool the skin. Furthermore, the grid itself provides shape stability to the water bolus, whereas the sides of the grid that are in contact with the patient’s skin provide flexibility. In addition, the water bolus was designed in a manner to enable an easy attachment to the deep DHT equipment by a sliding mechanism.

This thesis is about improving the television experience of visually impaired people (VIP). The company VFO, world leading in assistive technology for VIP, proposed the assignment after finding out that VIP still watch television but do not experience it like sighted users. First, background information was retrieved by literature research. Common causes of having a visual impairment and what kinds of impairments exist were derived. Existing knowledge of television watching by VIP was still undersized; no recent study has been done. The main insight obtained from the literature research was that VIP do watch television as much as sighted people. However, VIP experience several problems while watching television that they are not yet able to solve, such as difficulties with understanding a story or missing important details. Currently some products exist to enhance the television experience of VIP but none of them fit to all visual impairments or solves their actual problem. During this project a study was done to understand the context of VIP watching television and what problems come to light while using the television. In addition to struggles with positioning and using the television, VIP are having a hard time following the content of TV-programs. Details are missed, subtitles are too small to read or disappear too quickly and fast-changing images make it hard to focus on the subject. In this thesis, a solution will be presented for the inability to follow a conversation because of fast-changing images and the incapability of reading subtitles. Several ideas were generated. Four concepts were formulated after discussions and brainstorms with experts of different expertises such as visual aiding products, vision of VIP and about possibilities of tracking content in a video fragment. These four concepts were tested with VIP to validate the working principle. One concept was found to be applicable for all kinds of visual impairments and a genuine help for VIP: Voices. The concept changes the single voice of spoken subtitle equipment into four voices (two male and two female). This concept needed some improvement according to VIP: making the voices more natural. Furthermore, the Dutch voices that can be used by VFO are Xander and Claire, just one male and one female voice. This evoked one more improvement that should be made: developing dual voices out of one existing voice. Several possible voices were made with editing the existing ones. A survey was done that indicated the best voices and the needed pitch difference (two semitones) between two voices to perceive them as a different personality. Video fragments of Dutch television with subtitles were edited with these voices to test the final concept; SubSpeech, with VIP. This last research provided the insight that two semitones distance between two voices was not always perceived as two different personalities. However, the concept was perceived as intended and participants mentioned that several voices do help them understanding a conversation due to the indication of a changing speaker. With current knowledge SubSpeech will help VIP understand conversations of foreign languages better and will make them watch television more easily. A user scenario and a brief list of recommendations for developing the concept into a product is presented at the end of the thesis.

The primary purpose of this Integrated Product Design master thesis has two purposes. The first is to gain a deeper understanding of the needs of the elderly with dementia that causes undesired behaviour or Behavioral and Psychological Symptoms of Dementia, such as wandering during the night. The second purpose is to design CloudCuddle Senior: a lightweight and inflatable bed tent that keeps patients up to 120 kg in bed and creates a feeling of safety in various use cases such as home, caring home or the hospital. Data for this thesis were gathered by doing a literature study, making rapid prototypes and doing qualitative user tests. These methods generated knowledge for two sub-sections of the CloudCuddle Senior Design. The challenge of the Structural Design part was to come up with a bed tent concept that will be stiff enough to keep patients up to 120kg in bed while being lightweight to ensure mobility and consider nursing activities in and around the bed. The Experience Design of CloudCuddle Senior is about creating a safe and comfortable experience in bed that take the needs of people with dementia into account. The literature research results provide the support that patients with dementia need dynamic stimuli. However, research often focuses and compares mainly the type or the meaning of the stimuli such as Snoezelen, light therapy and music therapy while intensity through pace and amplitude often forgotten. More research into the intensity of therapeutic activities may conclude that designers of new interventions should focus on creating an intensity of dynamic stimuli that matches the patients need instead of focusing on the type of stimuli. A concept design is proposed based on the results of the Structural and Experience Design research. One of CloudCuddle’s bed tent’s significant characteristics is its inflatable structure. Although it was tried to design a more stiff design through solely inflatable elements, hard materials are required to meet the requirement of keeping 120kg patients in bed. The results on research from an Experience Design perspective implies that a bed tent that impairs vision on all sides except on one side offers a sense of safety while still being connected to the room in which the patients sleeps and a sense of control. The results of both the Structural and Experience Design research are combined in a final concept design for CloudCuddle Senior that should be prototyped and tested on strength and experience.

This report shows the process of creating a design proposal for a modular kitchen cabinet for the company Quooker. Quooker B.V. is a Dutch company famous for its water taps that instantly cook water, with its head office based in Ridderkerk. The rapidly expanding product portfolio of Quooker causes a complex installation and difficult integration of the products into kitchens. Therefore the assignment was set to design a modular kitchen cabinet that would ease the installation process and would help the consumer to use the available space inside the sink cupboard more efficiently.

The idea for this project was created by two Urologists at the Erasmus MC in Rotterdam. The design goal was to develop a diagnostic device that can be used to measure nocturnal (i.e. nightly) erections. The current device used to measure nocturnal erections was developed in the 1980s. There is a need for a modern tool that can be used in the diagnosis of erectile dysfunction. Erectile dysfunction (ED) is defined as the inability to achieve or maintain an erection sufficient to permit satisfactory sexual intercourse (Shamloul et al. 2013). A study from 2017, for the Rutgers Institute, found that in the Netherlands 9% of men suffer from ED (Seksuele gezondheid in Nederland 2017) Broadly there are two categories of ED, (1) psychogenic and (2) organic, each having their own underlying causes. Currently, there are limited diagnostic tools for patients with ED. These diagnostic tools are unable to provide reliable, or accurate data. In addition, these tools are often uncomfortable for the patient or are invasive. The most common diagnostic tool for ED is obtaining a detailed medical history followed by a sexual health questionnaire. The questionnaire asks a series of questions regarding sexual health and is often paired with a doctor's appointment where the patient will verbally communicate with a urologist regarding their symptoms and complaints. This can be an intimate or sensitive subject to discuss and miscommunications between patients and physicians about specific problems are common. Following the conclusion of the project, I plan to present a device that can measure the number, duration and intensity of nocturnal erections. The device should provide urologists and researchers insight into the physiology during a nocturnal erection. My results show that it is possible to obtain STO2 measurements in the penis using a tissue oximeter in both flaccid and erect penises. The final design includes the tissue oximeter prototype, an ergonomic design for the device and a design for the user interaction.

In Turkey, roughly 3000 children and adolescents are diagnosed with cancer every year (Kebudi, 2012). Although there are different types of pediatric cancers, their trajectory is similar and filled with various physical and psychosocial challenges for the patients and their families. Moreover, cancer usually causes a drastic life change for the whole family. To adjust to the changes and cope better with the challenges, it is crucial that children understand cancer, its course, and the treatment (Eiser & Havermans, 1992; Scott, Prictor & Watt, 2003 as cited in Mant et al., 2018). However, in Turkey, parents often avoid sharing cancer-related information with their children, which hinders children’s understanding, adjustment, and coping (Dr. N. Yıldız Silahlı (MD), personal communication, 2022). Therefore, this thesis aims to improve children’s understanding, adjustment, and coping by nudging parents into changing their attitudes and encouraging children to express themselves. To do so, the project utilises the power of play. The project starts by exploring the context of pediatric cancers, the factors that affect children’s understanding, adjustment, and coping, and the strategies to utilise play in the pediatric cancer context through a literature review. Then, the project analyses families’ current experiences, needs and wishes, and the barriers and opportunities in the context through generative interviews with the families and interviews with healthcare professionals, which reveal the reasons behind parents’ attitudes and another key problem: limited emotional sharing between children and parents. Based on the interview results, the project visualises the users’ experiences, needs, and challenges through personas and a user journey map, which shows the need of focusing on the hospitalisation stage. In the light of new findings, the project analyses and reframes the initial design problem and envisions the solution space by defining the design goal, vision and requirements. After generating various solutions that fit within the envisioned space through ideation and conceptualisation, the project introduces the final design: AstroMission, a space-themed role-playing game that aims to facilitate the emotional connection between children and parents. AstroMission consists of several elements with different functions: 1. Storyline: It is a metaphorical representation of cancer, treatments, and psychosocial challenges. Parents can use this storyline to give children cancer-related information. 2. Missions: They are play opportunities that require the collaboration of children and parents. Their content nudges families into talking about cancer and sharing their emotions with each other in a fun way. 3. Emotion puppets: They are a set of toys that represent four basic emotions of joy, anger, sadness, and fear. They help children to express their feelings. Also, some missions require the family to play with them. 4. Hospital room decorations and objects: They reframe the hospital room into a less scary, even fun environment for children. Also, some missions require the family use the objects in the room. 5. Mobile app: It presents the missions and the story of the game to the family. Also, it has a social function of connecting the families going through the same experience. Due to the project duration, the project iterates on and validates only the first three elements of the game with the users. However, user evaluations show that AstroMission is desirable and holds great potential to facilitate cancer-related conversations and emotional sharing between parents and children throughout the cancer trajectory. Lastly, the project shows how to put AstroMission into practice by proposing a material and production method and estimating implementation costs. Also, the project presents the recommendations for further development of AstroMission. To conclude, the outcome of this project creates value for the users by improving children’s understanding, adjustment, and coping, and alleviating parents’ psycho-emotional burden. It also creates value for the hospitals by improving the user experience.

In the Netherlands an estimated amount of 1.75 million people are suffering from asthma, from which an estimated amount of 300,000 are children. Even though the treatment of asthma has come a long way, nonadherence in asthma patients regarding their treatment remains high. This nonadherence is in part linked to the visual appearance of asthma inhaler devices and the ease of incorrectly interacting with these devices. The combination of using a metered dose inhaler (MDI) with a (valved) spacer chamber significantly decreases the likelihood of device interaction issues, but it worsens the visual appearance of the device, making it the least popular asthma inhaler device and also the least likely to be used in public. A concept has been developed in order to make the combination of an MDI + spacer chamber more appealing to use amongst younger asthma patients (children), especially in public. This concept consists of a housing which can hold and disguise an MDI + spacer chamber whilst providing an outwardly appearance of a sports water bottle. Interaction with this concept also provides an outwardly appearance as a person who is drinking from a sports water bottle, as opposed to that of a patient who is inhaling from a medical device. This concept aims to provide the advantages of an MDI + spacer chamber whilst simultaneously decreasing factors of embarrassment and/or reluctance to use such a device in public. Finally a usability study and a user experience (UX) have been conducted in order to evaluate whether the developed concept performs as intended.

The coeliac disease is an autoimmune disease caused by the ingestion of gluten affecting people with a genetic disposition. Gluten is a protein that can be found in wheat, rye and barley but it can also be used as protein filler in ice creams and soup. The only treatment for patients is to follow a strict gluten-free diet. Due to the restrictive nature of the diet, coeliac people have to develop new habits and routines to overcome uncomfortable situations at home and social situations. Different studies demonstrated that coeliac people are affected emotionally by social events. Coeliac people have to avoid food contained food, be aware of the gluten cross-contamination and find proper gluten-free options. This might lead to the development of anxiety and stress. This is a master report that gathers the research and the design activities to investigate how to create a safe environment for coeliac people during social events. The project was developed through converging and diverging design approaches involving remote user research, literature review and iterative cycles of ideations, development and testing. The project focused mainly on two areas: the perception of the gluten-free diet and the coping strategies or problem-solving skills used during social events. The research approach includes context research as base knowledge about coeliac disease, the challenges of the gluten-free diet, and coping strategies. The user research involved coeliac people to lead the development of a solution that would embrace their needs and values. At the end of the user research, a Framework was developed to describe the context of the social events for coeliac people. The design goal of the project was identified as the project aims to enhance the feeling of security for coeliac people by increasing empathy and decreasing negative emotions. Different concepts were developed according to iterative conceptualizations and evaluation tests of low fidelity prototypes with participants. The insights gathered helped to generate a final concept. The final concept is an event planner app that gives information about how to create a safe environment for coeliac people and more. The final user tests have been conducted in part in person and part remotely with participants who evaluated the possibility to create a safe environment and create empathy. The results demonstrated that by using the final concept it is possible to generate a safe environment and generate empathy. Participants had the possibility to immerse themselves in the challenges that coeliac people face daily. Coeliac people indeed felt to be secure cause people would have the correct information about the preparation of the environment and gluten-free food.

The founders of start-up Scoozy saw an opportunity in the market for electric mobility. The mobility scooter has been driving electric for over 40 years, but has barely innovated. The start-up came up with an alternative for the current mobility scooter: Scoozy. A first working prototype was build in 2017 and tested with potential users. This led to many useful insights for the required improvements before Scoozy could go to the market. One point of attention was the ergonomics of the seat. The seat is not adaptable to the diversity in the human body and thus not suitable for all users. This raised the question: How does this influence the comfort experience of the users and how can this be improved? These problems and questions were the base for this thesis assignment: Design the seat of a mobility scooter by analysing current desires of the user and Scoozy and testing with models in order to improve the usability and ergonomic functionality of the seat.

This project is about designing a tool to help informal caregivers provide better dementia care experiences for the people-with-dementia. There are many different non-pharmacological interventions that can be applied to help deal with the symptoms of dementia. Both understanding the knowledge of non-pharmacological interventions and knowing the people-with-dementia is necessary for informal caregivers to personalized apply these interventions during the daily care. This project is researching this topic and developing a tool to support informal caregivers. The project follows the double-diamond model. Discover: desk research, context inquiry, in-depth interview and collage were applied and different stakeholders were involved to dig deeper into the research questions. Define: The research results were summarized and the design problem, target users and use scenario were defined. Develop: Multiple concepts were created and evaluated by the Objective Weighted during the develop phase. Deliver: One concept was chosen to further detailed, evaluated, iterated and finally delivered. The outcome is a platform, which is an app, for informal caregivers to search and learn dementia-related knowledge and discuss with each other or with the experts. Users can learn different non-pharmacological interventions and knacks on the platform as well.

At the moment design is taught in primary education. Teachers often use the design cycle which consists of six phases: 1) Exploring & formulating the problem, 2) Generating & selecting ideas, 3) Generating & selecting concepts, 4) Building prototypes, 5) Testing & optimising and 6) Presenting. There are several tools available for teachers to use when doing a design assignment in class. These tools are focused on exploring, ideating and presenting, but tools for prototyping are missing. In a previous project Nadine Rodewijk developed a game, the Prototype-discussion-game, which was meant to help children in purposefully prototyping. This game is the starting point of this project and the goal of this project is to develop materials that are a contribution to the available tools for designing in primary education and make children use prototyping in a meaningful way.Explorative research, interviews, observations and literature, show that children often do not have a goal when prototyping, while experts use prototyping to find things out. Designing is an iterative process and prototyping allows you to iterate. At the moment children often only make one prototype at the end of their process for communication purposes.In this project three tools are (further) developed in order to stimulate the children to purposefully prototype and use prototyping to iterate in their design process. Due to COVID-19 all the tests in this project could not be performed in schools, since all schools were closed. Therefore, all the tools are tested at home. One of the developed tools is the Skill tool. The goal of this tool is to teach children necessary skills for prototyping. When children do not know how to make things, they will not be able to make meaningful prototypes in a design assignment. Children get a step-by-step instruction in text and image which they have to follow. In the last step the children need to apply the skill they just learned in a different context. This way children already have practised applying the skill in a different context before they have to create a specific prototype in a design assignment. Another tool is the Prototype-discussion-game of Nadine which is further developed. The goal of the game is to make children aware of the different goals prototypes can have. The Prototype-discussion-game is a card game in which groups of 3-4 children have to combine prototypes with goals. The children have five cards with different goals for prototypes on them and they need to combine one of the cards to a card with a prototype on it. The children need to give an argument for their choice and need to discuss which goal fits best with the prototype card. The tests in this project show that the game makes children aware of the different goals and is experienced as a nice and educational game to play. The last tool developed for children is the Iteration tool. The goal of this tool is to guide children through the necessary stages in order to iterate (see Figure 1). In order to iterate you first need to look forward and plan for the prototype you are about to make. Then you execute your plan and once it is finished, you look back and reflect on your progress and process. Lastly, you process your learnings and decide on what the next step would be before you enter the iteration model again by planning for your new prototype. The tool consists of multiple worksheets which are related to the stages of the iteration model. The tests show that using the Iteration tool helps the children to prototype purposefully. In this project there is also a tool developed for teachers. This Info booklet provides information about the role of prototyping in a design process. The booklet also provides examples and information about the tools developed in this project that can be used in class when prototyping. Teachers mentioned that this booklet is very informative and can be useful when preparing a design assignment.

This graduation report describes the design process of the antenna band of the myTemp system. The myTemp system is a high accuracy core temperature measuring device, that uses an indigestible measuring pill and an antenna band to measure the temperature inside the intestines. It is mainly used in thermo-physiological or exercise-related research, often to research how the core temperature changes in athletes when exercising in hot, humid environments. By researching this, heat-related illnesses or exertional heat strokes can be avoided that are caused by a too high core temperature. The main benefit of the myTemp system lies in the fact that the indigestible measuring pill does not contain a battery and can therefore be manufactured at a lower price than competitive products. This also means that there is no risk of battery leakage in the body. This requires that the system uses an antenna belt. This belt consists of a case containing electronics and a wire that goes around the torso of the user. This wire creates a magnetic field that is able to both charge and well as communicate with the indigestible measuring pill. In this project the main objective was to improve the comfort of the antenna belt, fit the belt to people with different body sizes, increase the reliability of the antenna-pill connection and increase the user experience. The project consists of three phases: the research phase and two ideation phases. In the research phase, relevant information is gathered about the context, user experience and the technology used. In the first ideation phase, multiple antenna configurations have been tested and compared to find an alternative antenna. In the second ideation phase, a user test has been conducted to improve the user experience of the device. At the end of the report, the design is presented and recommendations are given for future development.
