User engagement through multimodal feedback and involvement in game design with a wearable interface

Abstract

A wearable interface was designed, built and tested as a prototype to evaluate users’ engagement in a game setting. The wearable interface consisted of a light sensor and three different types of actuators: a RGB led, a buzzer and a vibe motor. Evaluations of the interface performance were conducted focusing on two main components: the multimodal feedback system and the involvement in game design over several rounds. Experimental results showed that our wearable interface is comfortable and imperceptible. Moreover, our wearable interface is simple enough for users to be able to add game modes based on social agreements. Our results demonstrate how meaningful multimodal feedback and self-directed involvement in game design can address several human factors challenges faced by user engagement designers.
