Abstract
A dual pointing device and method based on 3-D motion and touch sensors are provided. The dual pointing device includes a sensor including a first sensor sensing a motion in a space and a second sensor sensing a touch input, a movement-mode-determining unit determining a movement mode type using signals of the first and second sensors, and a pointer-moving unit moving a pointer on a display screen using at least one of the signals of the first sensor and the second sensor according to the determined movement mode type.
