ABSTRACT
Natural User Interface technology greatly changes the way we interact with computer systems, but does it perform as well as their traditional counterparts under pressure? By comparing a selection of user interface devices that provide a range of natural interaction systems, we explore how well the interface devices will perform in a command and control environment such as for a courier dispatcher. A Fitts' pointing experiment was used to make the comparisons and we found that a Multi-touch system performed the best in pointing and selection tasks, followed by mouse, Track-pad and lastly the Leap Motion hand tracking and gesture controller. It was noted that in order for any of the devices to operate at their optimum, then the graphical user interface and the hardware interface needs to be tightly bound together in order to optimize user task performance.
