Patent ID: 7898436

Claim:
An on-vehicle position detection system, comprising: a radiation emitting device for producing at least one beam which is appropriate to be reflected by a human body seated in the vehicle; a sensor device configured for detecting reflection of the at least one beam produced by the radiation emitting device and reflected by the human body including the torso, and for generating an output signal responsive to a reflection state of the at least one beam; and a control device coupled with the sensor device, the control device configured for receiving the output signal from the sensor device, and for determining whether the output signal corresponds with a first value indicative of a first position of the human body including the torso, or a second value which is different from the first value; wherein the control device is further configured for generating a control signal that is provided to a display device, the display device having an operation mode that includes simultaneously displaying a first view in a first viewing region of a display screen and a second view in a second viewing region of the display screen, wherein the control signal is adapted for switching on, switching off, or changing at least one of the functions of the operation mode when the control device determines that the output signal corresponds with the second value, wherein the first position corresponds to a normal position of the human body including the torso relative to the display device, and the second value corresponds to a position that deviates from the normal position by a predetermined amount.
