1. A system comprising:
- a two-dimensional (2D) touch detection system comprising a plurality of capacitive touch sensors coupled with a 2D touch detection controller and being operable to be activated and de-activated;
an additional three-dimensional (3D) gesture detection system comprising a 3D gesture detection controller and additional capacitive sensors arranged around the plurality of capacitive touch sensors and further comprising a touch detection electrode covering a touch sensor area of the 2D touch detection system being further configured to detect a touch on a touch sensor area of the 2D touch detection system, wherein the 3D gesture detection controller is communicatively coupled with the 2D touch detection controller, and the 3D gesture detection system being operable to be activated and de-activated;
wherein the 3D gesture detection system is configured to determine a gesture performed by an object in a 3D sensing space defined by said additional capacitive sensors and touch events with said touch detection electrode and to activate the 2D touch detection system and de-activate the 3D gesture detection system if a touch event has detected by the 3D gesture detection system.

Abstract
A system has a two-dimensional (2D) touch detection system operable to be activated and de-activated and an additional sensor operable in communication with the 2D touch detection system. The additional sensor is capable to determine whether a touch event has occurred or is about to occur and to activate the 2D touch detection system if a touch event has occurred or is about to occur.
