Abstract

Tilt operations with audio feedback can enable data input using handheld device, single handed and eyes free. This paper presents a prototype using 5 tilt positions for numeric and symbol input for calculator applications. Two tilt positions are mapped into a single digit or one operation symbol. Users click one physical key to indicate a tilt position and hear audio feedback. Controlled experiments showed that the tilt-click input technique is feasible and promising for small mobile devices.
