Claim 13:
14. A method for hand detection on a steering wheel, with at least one light source, at least one light sensor and a detection unit coupled to the at least one light sensor, the method comprising:
at least one light source emitting an emitted signal of light so that the emitted signal is directed from inside the steering wheel to a detection area, which is a portion of a surface of the steering wheel;
at least one light sensor detecting a reflected signal, which is a portion of the emitted signal that is reflected from the detection area into the inside of the steering wheel; and
the detection unit detecting a hand of a user on the steering wheel based on a detection of the reflected signal,
wherein the at least one light source comprises a first light source and a second light source, and the detection unit is configured to control the first light source and the second light source to emit the emitted signal alternatingly, so that only one of the first light source and the second light source emits the emitted signal at a time.
