Tangible Apps Bracelet: Designing Modular Wrist-Worn Digital Jewellery for Multiple Purposes

Most of today's wearable devices mainly focus on functionality and show large deficits in aesthetics and comfort. However, researchers and market analysts emphasise the importance of aesthetics for wearable technology to be successful. Smart Digital Jewellery has been proposed as an approach to seamlessly integrate technology into appealing, body-worn objects. In this work, we investigated how a smart digital multi-purpose bracelet should be designed in order to be attractive, functional, easily comprehensible, and easy to manage. We built the Tangible Apps Bracelet and evaluated it in a lab study. The Tangible Apps Bracelet integrates multiple applications in form of single elements that are threaded on a string. Participants experienced it very positively, easy to interact with, and rated its usability and user experience as very good. They particularly appreciated its simple interaction and display concept and the seamless integration of applications and digital components into an aesthetic piece of jewellery.
