UbiCompass - IoT Interaction with Wearables

Sammanfattning: As the number of connected devices around us increase through the development of Internet of Things (IoT), the need for interaction with these devices increase. This thesis aims to examine the benefits of using wearables to achieve fast at-a-glance interaction. A functional prototype, UbiCompass, was developed for a smartwatch that exploits the direction of the connected devices relative to the user. To demonstrate a wide area of functionality and to open up for further development, the prototype integrates with the Z-Wave standard. The concept was evaluated against an existing mobile application through a user study concerning smart home product interaction. 32 participants tested both devices, following a scenario, and the results were gathered through interviews, observations, System Usability Scale forms (SUS) and Nasa TLX forms. The results indicate that the smartwatch is generally preferred over the mobile, especially regarding simpler tasks.
