1. A method for controlling an input mode of a touch screen of an associated electronic device comprising a condition detection system, the method comprising:
- monitoring humidity in an area surrounding the associated electronic device using the condition detection system by detecting a first signal from an associated humidity sensor indicating a level of humidity in the area surrounding the associated electronic device and detecting a second signal resulting from an input on the touch screen indicating a presence of water on the touch screen;
determining, based on the humidity in relation to one or more predetermined humidity threshold values, if a first input mode (I) using only a capacitive sensing for the touch screen is to be used, or if a second input mode (II) using only a Z-force sensing for the touch screen is to be used for pressure detection, or if a third input mode (III) being a combination of the first and second input modes for the touch screen is to be used, andusing the determined input mode for receiving an input on the touch screen from an associated user of the associated electronic device.

11. An electronic device comprising:
-
a touch screen; at least two touch detection systems comprising a capacitive touch detection system and a Z-force touch detection system; a condition detection system, wherein the touch screen is configured for operation in one of a first input mode, a second input mode, or in a third input mode being a combination of the first and second input modes, a memory, wherein the condition detection system is configured to determine humidity in an area surrounding the electronic device by detecting a first signal from an associated humidity sensor indicating a level of humidity in the area surrounding the electronic device and detecting a second signal resulting from an input on the touch screen indicating a presence of water on the touch screen, the electronic device further comprising a humidity condition handling and processing unit configured to; determine, based on the humidity in relation to one or more predetermined humidity threshold values, if the first input mode (I) using only the capacitive touch detection system for the touch screen is to be used, or if the second input mode (II) using only the Z-force touch detection system for the touch screen is to be used for pressure detection, or if the third input mode (III) being the combination of the first and second input modes for the touch screen is to be used, and to set the determined input mode to be used by the touch screen for receiving an input on the touch screen from an associated user of the electronic device. - View Dependent Claims (12, 13, 14, 15)
