Characterizing non-visual target acquisition tasks with the aid of a tactile display: investigating factors beyond the classical Fitts’ theorem

Abstract

Interaction in most non-visual environments is limited to discrete units of input and feedback, such as keyboard and sound. The purpose of this study is to use the classical Fitts’ law to characterize target acquisition in a non-visual environment with continuous input devices and haptic feedback. Two groups of 21 severely visually impaired volunteers were… (More)
