ThumbTouch

UX Design / UX Research / Development

Intro

This project explores the possibilities of two common touch interactions, tapping and swiping, on deformable tablets. Deformable devices lack the structural support required for touch interaction. This was partially solved by using the support provided by the hand holding the device. On the surface of the device, the thumb of the holding hand was used for interaction. The study provides some design guidelines to leverage the capability of touch interaction on flexible handheld devices.
