Finger detection on touch screens for mobile devices

摘要

A method for dynamically controlling an input mode of a touch screen (10) for an electronic device (1) comprising at least one condition detection system (4), wherein the method comprises monitoring humidity in the surrounding of the electronic device (1) by means of the condition detection system (4), and determining, based on the monitored humidity in relation to predetermined values, which input mode is to be used for the touch screen and using the determined input mode for the touch screen.

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, and using the determined input mode for receiving an input on the touch screen from an associated user of the associated electronic device.
