Which tangible control for which visual task?
Céline Coutrix, Yann Laurillau · 2019
Many parameters may impact the performance of users while engaged in tangible user interaction. In this paper, we explore the impact of the combination of the tangible control and the visual display on the performance of a 1D target acquisition task. We consider three tangible controls: a slider, a knob and a wheel, and two visual displays for the same 1D target acquisition task: a circular cursor and a linear cursor. We found that matching the visual and motor task has an impact on the performance. This work has implications ranging from current design of Tangible User Interfaces to research on shape-changing Tangible User Interfaces.
