An Exploration of Absolute and Relative Cursor Positioning for Back-of-Device Input

 

 

Touch interactions on mobile devices impose several limitations, such as occlusion and reachability. Prior studies have shown that these challenges can be overcomed by allowing users to interact with the back-side of the device or back-of-device input. This form of input allows users to control an on-screen cursor from behind the screen, thus reducing occlusion and improving the performance of some routine tasks, such as pointing and steering.

In this project, we focus on studying selection mechanisms and suitable mode of cursor movement (Relative and Absolute) for one-handed back-of-device input.
