Paper Abstract:
|
There are many situations when users operate multiple windows simultaneously on a computer, such as looking at web browsers while making documents or searching program codes while writing programs. Generally, users can use a mouse or keyboard to change the focus among windows. However, when users frequently switch between typing and operating a mouse, they can be annoyed by having to move to shift devices, such as releasing a hand from the home position of a keyboard for mouse operation. In this paper, we propose an interface to reduce workload by enabling users to operate inactive windows when switching between typing and pointing. The interface recognizes hand gestures by using a depth sensor that images a keyboard entirely and uses the hand gestures for window operation. We implemented a prototype, evaluated task workload, and compared operation time of the proposed interface with mouse operation when typing and pointing are frequently switched between. The results suggest that using the proposed interface significantly reduces the task workload and operation time. |
