Abstract

See full text

A haptic sensing device, including a light source, an optical waveguide, a photoelectric sensor, and a housing. The optical waveguide includes a waveguide layer and a cladding, the cladding encloses the waveguide layer, and a refractive index of the waveguide layer is greater than a refractive index of the cladding. The waveguide layer includes a plurality of paths, the light source is disposed at an input end of each path, and the photoelectric sensor is disposed at an output end of each path. The light source, the optical waveguide, and the photoelectric sensor are accommodated in the housing. A plurality of contacts are distributed on the housing. When a contact is pressed, the contact is in contact with one path, and the path is deformed. When any two contacts are pressed, the two contacts are in contact with different paths.
