Abstract:Over the last century, the elderly population and the number of patients with chronic diseases has increased. Both numbers are related to each other since many older adults are suffering under chronic diseases such as type 2 diabetes, heart disease, different types of cancer, depression and anxiety, and dementia. However, the majority of these diseases can be prevented or treated with enough physical activity and a healthy lifestyle. Many older adults feel unmotivated ti increase their physical activity. One possibility to support and coach them are wearable devices. With the aid of this technology, the activity can be measured and presented to the older adults to motivate them. However, most activity trackers or coaches are not design for this target group and their needs. The common applications visualize the data in 2D with numbers and diagrams but a meaningful visualization, with which older adults can be motivated, is missing. This bachelor thesis describes the process of developing a meaningful data visualization for older adults with the aid of a wearable sensor. The sensor used for this research is the Mox sensor, developed by Maastricht Instruments. This final design consists of the final prototype, a controller box and a manual. The design of the prototype is an artificial flower, which can bloom depending on the activity of the user. Furthermore, integrated fiber optic cables combined with an LED, makes the prototype visually attractive and allows it to change colors based on the users progress. The design was tested by three participants over at least 24 hours. The results show that the design can lead to a higher activity level of the participants, at least for a short term. Furthermore, we concluded that a 3D visualization is more convenient compared to a 2D visualization for this kind of target group and that the modern design together with integrated fiber optic cables makes the user curious and interested in the design. Additionally, a personal goal option in combination with an easy understandable controller keeps the user independent and encourage him or her to start an interaction.
