Abstract

Research on pointing devices has shown that rate control is appropriate for isometric and elastic devices but not effective when input control is purely isotonic. Human hand has been generally considered as an isotonic device. Therefore, pointing devices that are directly controlled by hand movements (e.g., the mouse) are based on position rather than rate control. In this work, we study the relevance of rate control in low-resolution input. Taking into account elastic properties of the human wrist, this work explores designs that mix position and rate control when input is handled by constrained hand movements.
