Claim Text:
1. A hand-held pointing device, comprising: a main body comprising an axial direction, a first surface and a second surface, wherein the hand-held pointing device can be hold along the axial direction, the first surface and the second surface comprise a first transparent area and a second transparent area, respectively, the second surface is parallel to the axial direction and for lying on an operating surface; a first image sensing device disposed in the main body and configured to sense a first image through the first transparent area; a light emitting device disposed in the main body and configured to emit a light source through the second transparent area; a second image sensing device disposed in the main body and configured to sense a second image through the second transparent area; and a processing circuit configured to activate the second image sensing device to sense the second image for generating a second determination result when a first luminance of the first image lower than a first luminance threshold or activate the first image sensing device to sense the first image for generating a first determination result when a second luminance of the second image lower than a second luminance threshold, and determine and operate the hand-held pointing device either in a remote controller mode or in a mouse mode according to the first determination result or the second determination result.
