Zoofing!: Faster List Selections with Pressure-Zoom-Flick-Scrolling. OZCHI'09

The task of list selection is fundamental to many user inter-faces, 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 selec-tion 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, zoof-ing outperforms (and is preferred to) traditional scrolling, flick-based scrolling, and OrthoZoom. We analyse experi-mental logs to understand how pressure was used and dis-cuss directions for further work. Author Keywords Zooming, scrolling, flicking, list selection, pressure
