Abstract

To find ways to improve users' performance of tasks that involve both scrolling and pointing, we studied three dual-stream input methods, with one stream for pointing and one for scrolling. The results showed that a mouse augmented with a tracking wheel did not outperform the conventional single stream mouse. Two other methods, a mouse with an isometric rate-control joystick and a two handed system significantly improved users' performance.
