Abstract
While multi-touch design allows natural and flexible figure gestures in interacting with mobile devices, the palm-size screen often limits its potential in application and arouses issues such as inefficient mode switch and incomplete gesture. To enrich the vocabulary of finger gestures in user interaction, we present Thumb Widgets, a mechanism that adopts thumb as assisted input channel to enhance the capabilities of multi-touch on touch-based mobile devices. Thumb Widgets expand the design space in gesture-based UIs and promote efficiency for tasks such as mode switching, parameter setting, etc. Also, Thumb Widgets enable incomplete gestures to be performed around the periphery of the device.
Supplementary Material
The auxiliary material is a demo video which demonstrates the potential application scenarios of our technique as well as a preliminary prototype implementation. The file format is mp4. Regular video player software would be capable to view this demo.
