SmartKey

摘要

SmartKey is a new virtual keyboard animation for handheld devices designed to make key selection easier for people with situational and motor impairments. The nearest key to cursor expands in four directions using the available space of nearby keys. Target expansion is accomplished with an occlusion factor of 0% and without any sideways motion. The two studies conducted with able-bodied and motor-impaired users showed that subjects performed better with SmartKey than with traditional virtual keyboard.
