A comparative investigation into two pointing systems for use with wearable computers while mobile

Target selection is a task carried out by many wearable computer users. Conventional desktop pointing devices such as mice are not appropriate for the wearable user as they are designed for use within the conventional desktop paradigm. Although many pointing systems have been devised for use with wearable computers, little empirical research has been carried out. This research investigates two different target selection systems: a touch screen stylus and an off-table mouse. This research takes a novel approach and evaluates users while moving and stationary. Twenty participants wore a wearable computer and selected targets while stationary and while mobile, input times and the participants' task load were recorded.
