Abstract
Previous studies have measured the speed and accuracy of voice input versus devices such as keyboards and mice. Other studies have shown that users will naturally provide input via simultaneous channels. While these studies indicate that voice might be used to improve the efficiency of a human-computer interface, they provide little assistance in predicting how much difference would be made by adding voice as a parallel input channel for common tasks. This paper presents a user study which measures how long it takes users to create drawings with a graphical editor. Our control group used the mouse as an input device, and our experimental group used a discrete-word voice recognition system in combination with the mouse. The combination system reduced task completion time by as much as flfty-six percent, with an overall reduction of more than twenty-one percent. We used an existing graphical editor originally designed to receive mouse input; we expect that a system explicitly designed to use parallel input channels could significantly improve our results.
