摘要： In a sensing system and a method for obtaining a position of a pointer, the sensing system includes a sensing area, a reflective mirror, an image sensor and a processing circuit. The reflective mirror is configured for generating a mirror image of a pointer when the pointer approaches the sensing area. The image sensor is configured for sensing the pointer and the mirror image thereof when the pointer approaches the sensing area. When the pointer approaches the sensing area, the processing circuit calculates a coordinate value of the pointer according to an image sensed by the image sensor and a predetermined size of the pointer. The pointer forms an imaginary orthographic projection in the sensing area, the processing circuit regards the imaginary orthographic projection as a round projection, and a radius of the round projection is the predetermined size.

摘要： An optical sensing system includes a sensing area, a reflective mirror, a first image-sensing device, a second image-sensing device, and a processing circuit. The sensing area is an area in which a plurality of pointing objects may execute touch operation. The reflective mirror generates a mirror image of the sensing area. The first image-sensing device and the second image-sensing device respectively capture images including all or part of the pointing objects in the sensing area, and all or part of the pointing objects in the reflective mirror. The processing circuit generates candidate coordinates according to the images captured by the first and the second image-sensing devices, and obtains the locations of the pointing objects from the candidate coordinates by means of the symmetric relationship between the point objects and the corresponding mirror images with respect to the reflective mirror. In this way, the optical sensing system can perform multi-touch operation.
