Abstract

We present Adaptive Pointing, a novel approach to addressing the common problem of accuracy when using absolute pointing devices for distant interaction. The intention behind this approach is to improve pointing performance for absolute input devices by implicitly adapting the Control-Display gain to the current user's needs without violating users' mental model of absolute-device operation. First evaluation results show that Adaptive Pointing leads to a significant improvement compared with absolute pointing in terms of movement time (19%), error rate (63%), and user satisfaction.
