| 摘要 |
The invention relates to a sensor module comprising: a plurality of optical emitters (5a, 5b) configured to emit light beams (9a, 9b) towards a detection space (E); a plurality of optical sensors (7) configured to capture the light of the light beams (9a, 9b) that is diffused by a control element (M) used by a user in order to perform a gesture intended to trigger the execution of a command; and a contact surface (19) that is at least partially transparent to the light of the light beams (9a, 9b) and placed upstream of the optical sensors (7). According to the invention, part of the optical emitters (5b) is configured to emit short-range light beams (9b), of which the light diffused by the control element M is captured by the optical sensors (7). |
