Abstract
An input device includes an optical sensor which senses an object on a plane where the emitted light travels, an optical member which changes a path of the light emitted from the optical sensor, and a processing unit which performs input processing based on sensing results of the optical sensor; the optical sensor and the optical member form a first sensing surface consisting of a planar region in which the light emitted from the optical sensor travels and a second sensing surface that is farther from the optical sensor than the first sensing surface, and the processing unit performs the input processing based on a first sensing result of the optical sensor on the first sensing surface and a second sensing result of the optical sensor on the second sensing surface.
