Contributor Van der Helm, A.J.C. (mentor) Tempelman, E.

In fact, more than 65% of snorer show the correlation with sleep position, mostly the supine position. For these position dependent snorers, positional therapy during the sleep has been proved to be effective. The sleep position trainer (SPT),which trains snorer’s sleep behavior to avoid the supine position by wearing the device around the chest just above the upper abdomen during sleep, has been developed by the medical technical company Night Balance. With the ambition of helping 500,000 people by 2020, the product requires innovation on many different levels including, it is expected, on new materials. Therefore, the company cooperates with the LTM project to develop a new generation of SPT that involves novel smart materials and new technology. The LTM project is an EU-funded project which aims to develop a completely new generation of smart materials that combine touch sensitivity with luminosity. The materials that the project is based on are polymeric composites and flexible OLEDs. This graduation project was a research and design exploration with the scope of smart materials and the future context. A unique method is used in this project. Two streams, the design stream and the material stream go in parallel and emerge in the final stages of the project. The design stream mainly addresses the question of who is the target user of the new SPT and what is the future vision of the new SPT. By a look at patient information, related product, literature resources, and interviews with physicians, people who snore were defined as a promising target group for further investigation. Through self-reflection diaries, observations and interviews, snorers’ sleep routines, concerns and needs were collected and analyzed, from which it was found that snorers do need a product that can help them solve their snoring problem. This product should be able to offer reliable treatment for snoring, have an attractive appearance with an energetic and healthy feeling and be a comfortable product where people feel pleasant and relaxed in using it. In addition, it was also found that sleep quality is not only determined by how people sleep, but also other phases around sleep, like bedtime routines, people’s state of mind before sleep and how people wake up in the morning, which would be an interesting field for the new SPT. The material stream is mainly focused on analyzing the usability and user experience problem with the current SPT and the search for suitable smart materials for the new product interface. By analyzing the subjective usability report from the company and literature resources on smart materials, the LTM materials were finally chosen for improving the product to make its interface more easy and understandable. The design goal was formulated based on the research results from both design stream and material stream. The Sleep Position Trainer was to be a tool that guides snorers in taking care of their whole sleep experience in a relaxing and intimate way. Through a meaningful form of interaction with the LTM material, people would experience the new SPT as being more pleasant, easy and intuitive to use. After a long and comprehensive conceptualization process, a concept was created and chosen for further development. The concept provides a complete sleep care service, except for its positional therapy during sleep. It also offers a personalized bedtime reminder, deep breathing practices for relaxation before sleep and a pleasant wake up alarm. In addition, a new form of interaction was formulated for each stage of use. Through two design iterations of demonstrating-building-testing cycles, different aspects of the concept, i.e. the light pattern for bedtime reminder, the interactions for the guiding before sleep and waking up in the morning, were tried out, evaluated and improved, leading to the final design decision “SLEEP.CARE”. “SLEEP.CARE” is a novel healthcare product for snorers. It not only mitigates user’s snoring problem, but also offers a whole set of sleep care services to improve their sleep quality. It consists of two parts: stimulation and detection. The stimulation part is a very small device that users can wear on their wrist like a bracelet. The detection part is a patch worn on the user’s torso for transmitting the sleep position signal to the bracelet. The user mainly interacts with the new SPT though the bracelet. A novel and smart interaction has been developed especially for the wristband based on the smart materials from the LTM project. The user would experience an easier and more pleasant to interaction with the new SPT with its holistic product interface. No physical button is on the new SPT as the whole product is sensible and users can interact with the product by easy and understandable hand gestures. In the end, recommendations were given to the LTM Project for further developing the interactions with materials and to the company for developing the next generation SPT.
