Abstract: An optical touch device with a detecting area includes light guide components, a light source module, a light detecting component and an auxiliary light guide component. Each light guide component includes a first light emitting surface. The light guide components includes a first light guide component and a second light guide component. The auxiliary light guide component and the light detecting component are disposed between two neighboring ends of the first light guide component and the second light guide component, and the light detecting component includes a light detecting end. The auxiliary light guide component is positioned between the light detecting component and the detecting area and includes a first light incidence surface, a second light incidence surface and a second light emitting surface connected between the first light incidence surface and the second light incidence surface. The optical touch device can effectively avoid the blind zone problem.

Abstract: An optical pointing device includes an illumination system, an imaging system and at least one diffraction element. The illumination system includes a light source for providing a light beam to a reflective surface outside the optical pointing device. The imaging system includes an image sensor disposed on a transmission path of the light beam after being reflected by the reflective surface. The at least one diffraction element is disposed in the illumination system and/or the imaging system and disposed on the transmission path of the light beam to change the transmission path of the light beam. The present optical pointing device can achieve the advantage of small volume.
