An apparatus for detecting spatial movement of an object, includes a rotatable light emitting diode, first and second camera modules, and an image processor. The light emitting diode is configured for emitting light to the object. The first and second camera modules are arranged on opposite sides of the light emitting diode and configured for capturing the light reflected by the object, thus respectively forming a first image signal and a second image signal associated with the object. The image processor is configured for processing the first and second image signals and analyzing spatial position of the object relative to the first and second camera modules based on the first and second image signals, thereby determining spatial movement of the object.
