Abstract

This utility model discloses a computer peripheral device utilizing photoelectric conversion communication, including a mouse and a mouse pad. The mouse, in addition to basic buttons, a scroll wheel, and a 2D mouse movement sensor, also includes a light emitter and a magnetic element. The mouse pad includes a photosensitive receiver and a magnetic induction chip. The magnetic induction chip, in conjunction with the magnetic element, detects the mouse's specific position on the mouse pad. Simultaneously, based on the mouse's position, the photosensitive receiver directly below the mouse's projection is activated, while photosensitive receivers in other areas (not below the mouse's projection) are in standby mode. This avoids interference from other external light sources, as only the photosensitive receiver below the mouse's projection is active. This ultra-short-range photoelectric conversion wireless method eliminates the need for radio waves, fundamentally solving the problem of co-channel interference inherent in traditional radio waves. It also offers high transmission speeds. A similar design applies to the keyboard.
