Zusammenfassung:An optical touch device includes a foldable frame assembly, two image sensing units and two light emitting units. The foldable frame assembly comprises a first frame, a second frame, a third frame and a fourth frame. The two image sensing units are disposed on opposite ends of the fourth frame respectively. The two light emitting units are disposed on opposite ends of the fourth frame respectively and adjacent to the two image sensing units respectively. The frames of the foldable frame assembly are pivotally connected to each other such that the frames can rotate with respect to each other so as to be folded or expanded.
