Dynamic Mouse Speed Scheme Design Based on Trajectory Analysis

摘要

Windows GUI allows user to define pointer speed and precision, however, the settings are fixed and not adaptive to different pointing tasks in real time. This study proposes a dynamic mouse speed (DMP) scheme that dynamically changes the pointer speed by calling SPI_SETMOUSESPEED. Results show that DMP setting, on average, outperformed some commonly used Windows built-in settings. However, the advantage of DMP setting occurred more significantly for longer moving distance. For short moving distance, the advantage was not clear. In addition, the advantage of DMP was not on all directions. For some directions, especially when moving distance was short, Windows built-in settings outperformed DMP setting.
