Watch-Pointer: Touchless Interaction on a Smartwatch

Abstract

We present an exploratory study to evaluate Watch-Pointer (WP), a touchless gesture- and pointer-based interaction on a smartwatch, across six interactions and three conditions: standing, walking without, and walking with busy hands (i. e., carrying bags). Our results show that walking conditions negatively affected task completion time, along with mental and physical demands. Overall, participants’ feedback on the performed interactions was mixed: while most interactions were described as intuitive, map panning and list navigation were perceived as challenging when carrying extra weight. At the end, we outline some improvements for the WP.
