  • Patent number: 10120464
    Abstract: An optical touch system includes two touch devices, two optical sensing devices, and a processing module. When the optical touch system is in use according to an optical touch method, the two touch device are used to touch a touch surface and emit first light and second light with different wavelengths respectively. The two optical sensing devices are disposed at the circumference of the touch surface and individually receive the first light and the second light to generate an optical sensing signal. The processing module receives the two optical sensing signals and determines a touch position on the touch surface for each touch device according to the two optical sensing signals. Therefore, the touching by each touch device is independent, so the optical touch system and the optical touch method can allow touch operations for different purposes to be performed simultaneously.

  • Patent number: 9665189
    Abstract: A touch stylus capable of detecting pressure on its tip is disclosed in the present disclosure. The touch stylus includes a body, a tip, and a pressure sensing module disposed between the body and the tip for detecting a pressure on the tip. The pressure sensing module includes a lighting unit, a pressure sensing unit connected to the tip, and a controller electrically connected to the lighting unit and the pressure sensing unit. The pressure sensing unit detects a movement of the tip relative to the body, and generates a corresponding electrical signal. The controller receives the electrical signal to drive the lighting unit for generating a corresponding optical signal. A scintillating frequency of the optical signal and a value of the electrical signal are in direct proportion, and an optical detector can transform the optical signal into the pressure on the tip.
