Abstract

The task of list selection is fundamental to many user interfaces, and the traditional scrollbar is a control that does not utilise the rich input features of many mobile devices. We describe the design and evaluation of zoofing---a list selection interface for touch/pen devices that combines pressure-based zooming and flick-based scrolling. While previous flick-based interfaces have performed similarly to traditional scrolling for short distances, and worse for long ones, zoofing outperforms (and is preferred to) traditional scrolling, flick-based scrolling, and OrthoZoom. We analyse experimental logs to understand how pressure was used and discuss directions for further work.
