A control system comprising: a panel display configured to display information to a user, the displayed information including a control region; a light sensor (12, 14) configured to receive light as it is reflected by an object approaching the control region and to provide an output signal in response to the received light; a processing circuit configured to receive a signal based on the output signal from the light sensor, and process the received signal to determine whether the control region has been actuated, characterized in, that the displayed information further includes a non-control region, that the light sensor (12, 14) is configured to receive light as it is reflected by an object approaching the non-control region, that the processing circuit is configured to differentiate between the control region and the non-control region, record a time at which the light sensor (12, 14) receives the reflected light and compare the recorded time to a time at which pixels corresponding to the control region are illuminated, and determine whether the object is approaching the control region or the non-control region, and that a characteristic of the light received by the light sensor is a phase of light or a timing of light. a panel display configured to display information to a user, the displayed information including a control region; a light sensor (12, 14) configured to receive light as it is reflected by an object approaching the control region and to provide an output signal in response to the received light; a processing circuit configured to receive a signal based on the output signal from the light sensor, and process the received signal to determine whether the control region has been actuated, receive a signal based on the output signal from the light sensor, and process the received signal to determine whether the control region has been actuated, characterized in, that the displayed information further includes a non-control region, that the light sensor (12, 14) is configured to receive light as it is reflected by an object approaching the non-control region, that the processing circuit is configured to differentiate between the control region and the non-control region, record a time at which the light sensor (12, 14) receives the reflected light and compare the recorded time to a time at which pixels corresponding to the control region are illuminated, and determine whether the object is approaching the control region or the non-control region, and that the displayed information further includes a non-control region, that the light sensor (12, 14) is configured to receive light as it is reflected by an object approaching the non-control region, that the processing circuit is configured to differentiate between the control region and the non-control region, record a time at which the light sensor (12, 14) receives the reflected light and compare the recorded time to a time at which pixels corresponding to the control region are illuminated, and determine whether the object is approaching the control region or the non-control region, and that a characteristic of the light received by the light sensor is a phase of light or a timing of light.
