Touching object and optical touching assembly using the same |
摘要 |
An optical touching assembly, including a display device, a sensing device, and a touching object, is provided. The display device has a touching area. The sensing device is electrically connected to the display device. The touching object is adapted to enter the touching area, such that the sensing device senses the motion of the touching object to control the display device. The touching object has an optical controlling element that generates light along with the motion of the touching object. The sensing device senses a characteristic variation of the light to trigger at least one operating function of the display device. |

1. An optical touching assembly, comprising:
a display device comprising a touching area; a sensing device electrically connected to the display device; and a touching object adapted to enter the touching area, and the sensing device sensing a motion of the touching object to control the display device, wherein the touching object comprises an optical controlling element that generates a plurality of first lights along with a variation of the motion of the touching object, and the sensing device senses a characteristic variation of the first lights to trigger an operating function of the display device, wherein the optical controlling element comprises a plurality of optical controlling elements that are arranged around a center axis of the touching object, and the characteristic variation of the first lights generated by the optical controlling elements ascends or descends gradually in sequence around the center axis based on the motion of the touching object in a clock wise or a counter clock wise direction. |
