An input system includes an input device including at least one of a first reflecting section having a reflectance varying in a longitudinal direction, and a second reflecting section having a reflectance varying in a rotational direction, a detection section adapted to detect reflected light from at least one of the first reflecting section and the second reflecting section, and a processing section adapted to obtain at least one of movement amount information of the first reflecting section in the longitudinal direction, and rotation amount information in the rotational direction of the second reflecting section, based on the detection result in the detection section. |
