Abstract

This paper explores the potential uses of pressure input from multiple digits (i.e., all 4 fingers and the thumb) of one hand squeezing a mobile device: multiple digits may provide multiple inputs. The potential advantages for mobile interaction include freeing the second hand for other tasks, and providing access to multiple functions simultaneously. A range of possible interactions is discussed including the benefits and challenges posed by complex pressure-based input on mobile devices. An example usage scenario is described and tested: pressure-based input for simultaneous zooming and rotating in a map task. Results suggest multi-digit pressure input may be a useful means of interaction with mobile devices.
