Claim 0:
1. A system for hand detection on a steering wheel, comprising:
at least one light source adapted to emit an emitted signal of light so that the emitted signal is directed from inside the steering wheel to at least one detection area of a surface of the steering wheel, the detection area being at least partially transparent for the emitted signal;
at least one light sensor adapted to detect a reflected signal, which is a part of the emitted signal that is reflected from the detection area into the inside of the steering wheel; and
a detection unit coupled to the at least one light sensor and adapted to detect 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.
