Abstract
In a sensing system and a method for obtaining a location of a pointer, the sensing system includes a sensing area, a reflective mirror, a first image sensor and a second image sensor. The reflective mirror is configured for generating a mirror image of the sensing area. The sensing system utilizes the above two image sensors to sense the pointer disposed in the sensing area and a mirror image of the pointer for obtaining two coordinate values. And then the sensing system endues each of the two coordinate values with a weighting factor for calculating the location of the pointer.
