Effect of Relocated Thermal and Pressure Stimuli on Vibrotactile Sensitivity

Relocated haptic feedback from the fingertip to the proximal phalanx can alter the perception of physical interactions by simultaneously displaying relocated multimodal tactile cues. However, how these relocated tactile cues alter the vibrotactile sensitivity of the fingertip remains unclear. This two-site stimulation study employs a...

Exploring solutions for finger tremor patients: Designing finger tremor suppression through passive wearable

This report presents an explorative study in finding solutions for finger tremor patients diagnosed with Essential Tremor (ET). Tremors restrict patients from performing delicate movements, creating difficulty in daily activities, such as drinking, writing, cooking or eating. Besides the challenges in performing tasks, social anxiety often...

Redesigning a Haptic Glove for New Features and Improved Assembly

This report describes the development of a redesigned haptic glove for SenseGlove, a Delft-based startup specializing in haptic technologies for use in Virtual Reality. Their Nova product line offers force feedback, haptics, and finger tracking to increase immersion in VR and provide intuitive interaction with virtual objects for training...

Developing hybrid force feedback: coupling brakes and motors can reduce the total actuator size and improve haptics quality

Hand-worn haptic systems must be able to produce high-quality haptics while also being lightweight and energy-efficient. In order to meet market expectations, research is being done into novel drivetrains that may be implemented in hand worn devices. This is being pushed forward by the growing demand in the virtual reality sector, which is...

Machine Learning for Cardiovascular Outcomes from Wearable Data: Systematic Review from a Technology Readiness Level Point of View

Background: Wearable technology has the potential to improve cardiovascular health monitoring by using machine learning. Such technology enables remote health monitoring and allows for the diagnosis and prevention of cardiovascular diseases. In addition to the detection of cardiovascular disease, it can exclude this diagnosis in symptomatic...

Integrating shape memory materials in haptic technology as an aid for the visually impaired

There are approximately 285 million people worldwide living with a visual impairment and the rate of acquired blindness is expected to continue increasing. Assistive technology for them is progressively being developed in order to enable independent living. For the blind and visually impaired, the tactile sense is the primary source of...

Towards orientation estimation using a loosely attached IMU with a recurrent neural network

Inertial measurement units (IMUs) are getting more and more incorporated into our lives due to their improving accuracy, lower cost and smaller sizes. Applications for inertial-based orientation estimation can already be found in the field of computer vision, aerospace engineering, robotics, navigation, biomechanics, health monitoring and sports...

Identifying Children's Activities: Development of a wearable to assess theactivities performed by free-living children

Dutch children achieve an insufficient amount of physical activity. For that reason, Delft University of Technology is looking to develop a wearable that contributes to motivating children to move more frequently and more intensely while collecting data on the movements made by its wearer. In this thesis it was investigated whether it would be...

DESC glove: Prototyping a novel wearable device for post-stroke hand rehabilitation

The human brain integrates tactile sensory information from the fingertips to efficiently manipulate objects. Sensory impairments due to neurological disorders, e.g. stroke, largely reduce hand dexterity and the ability to perform daily living activities. Several feedback augmentation techniques have been investigated for rehabilitative purposes...

Interface on the skin: Designing through a user centered approach

Since technological devices become smaller and our devices are more fused with our bodies, the logical next step is that technology will be placeable on our skin. In this thesis the design process towards a useful application of an interface on the skin is described. To get towards this design, several methods are used in the process. To shape...

X-eo: Researching & Designing for Rebellious play

This reports the graduation project aimed to investigate the occurrence of rebellious play through the X-eo prototype. Rebellious behaviour is often referred to as going against the norm and derives its value from breaking rules. Previous academic research (Gielen & Van Leeuwen, 2013), on the subject, has provided suggestions and techniques...

Omnivisi Earable: Continuous and non-invasive monitoring of vital signs

This project is an initiative of the Department of Surgery in Maasstad Ziekenhuis. In the department, two types of patients undergo abdominal surgery: 1) mobile obese patients and, 2) patients with cancer. These types of patients need personal contact and guidance, especially patients with cancer. However, nurses are overwhelmed with work and...

Wearable Fabry-Pérot Antenna

A wearable version of Fabry-Pérot antenna is presented. This is a simple way of designing a medium-To high-gain antenna with low back radiation. The study of the effect of antenna bending in the performances is presented. Besides, the replacement of a superstrate layer by a metallic frequency selective surface is proposed. In this way, there...

The I in Team: Mining Personal Social Interaction Routine with Topic Models from Long-Term Team Data

Social interaction plays a key role in assessing teamwork and collaboration. It becomes particularly critical in team performance when coupled with isolated, confined, and extreme conditions such as undersea missions. This work investigates how social interactions of individual members in a small team evolve during the course of a long...
