1. A method for processing signals of a touch-operable touchscreen of a portable device, wherein the method comprises:
- detecting a first touch signal indicating a first touch on the touchscreen;
identifying a touch region of the touchscreen corresponding to an area of the first touch on the touchscreen;
differentiating, on the basis of the detected first touch signal, between an input touch for at least one of inputting information and controlling the portable device and a gripping touch as a result of the portable device being gripped in the touch region of the touchscreen, wherein differentiating comprises determining a first touch parameter from the detected first touch signal, and comparing the determined first touch parameter with a corresponding first comparative parameter;
rejecting the detected first touch signal as an input touch when the first touch signal is attributed to a gripping touch;
altering the display of the touchscreen, wherein altering comprises reducing one of the display around the touch region and the entire display;
increasing the touch region;
detecting a second touch signal associated with a second touch on the touchscreen, wherein the second touch takes place within the increased touch region;
differentiating, on the basis of the detected second touch signal, between an input touch and a gripping touch, wherein differentiating comprises determining a second touch parameter from the detected second touch signal, and comparing the determined second touch parameter with a corresponding second comparative parameter, the second comparative parameter being more restrictive than the first comparative parameter; and
rejecting the second touch signal as an input touch when the second touch signal is attributed to a gripping touch.

Abstract
A technique is disclosed for processing touch signals of a touch-operable touchscreen. One aspect of the method comprises detecting a touch signal indicating a touch on the touchscreen, differentiating, on the basis of the detected touch signal, between an input touch for inputting information and/or for control purposes on the one hand and a gripping touch resulting from a user gripping the touchscreen on the other, and rejecting of the detected touch signal as an input touch if the touch signal is attributed to a gripping touch.

12. A non-transitory computer-readable medium encoded with a computer program for carrying out, when the computer program is run on a computer device, a method for processing signals of a touch-operable touchscreen of the computer device, wherein the method comprises:
-
detecting a first touch signal indicating a first touch on the touchscreen; identifying a touch region of the touchscreen corresponding to an area of the first touch on the touchscreen; differentiating, on the basis of the detected first touch signal, between an input touch for at least one of inputting information and controlling the portable device and a gripping touch as a result of the computer device being gripped in the touch region of the touchscreen, wherein differentiating comprises determining a first touch parameter from the detected first touch signal, and comparing the determined first touch parameter with a corresponding first comparative parameter; rejecting the detected first touch signal as an input touch when the first touch signal is attributed to a gripping touch; altering the display of the touchscreen, wherein altering comprises reducing one of the display around a region of the touch on the touchscreen and the entire display; increasing the touch region; detecting a second touch signal associated with a second touch on the touchscreen, wherein the second touch takes place within the increased touch region; differentiating, on the basis of the detected second touch signal, between an input touch and a gripping touch, wherein differentiating comprises determining a second touch parameter from the detected second touch signal, and comparing the determined second touch parameter with a corresponding second comparative parameter, the second comparative parameter being more restrictive than the first comparative parameter; and rejecting the second touch signal as an input touch when the second touch signal is attributed to a gripping touch.

13. An apparatus for displaying content, comprising:
-
a touchscreen for displaying content and for use by means of touch within an input region; and a processor system which is designed to carry out a method for processing signals of the touchscreen, wherein the method comprises; detecting a first touch signal indicating a first touch on the touchscreen; identifying a touch region of the touchscreen corresponding to an area of the first touch on the touchscreen; differentiating, on the basis of the detected first touch signal, between an input touch for at least one of inputting information and controlling the portable device and a gripping touch as a result of the apparatus being gripped in the touch region of the touchscreen, wherein differentiating comprises determining a first touch parameter from the detected first touch signal, and comparing the determined first touch parameter with a corresponding first comparative parameter; rejecting the detected first touch signal as an input touch when the first touch signal is attributed to a gripping touch; altering the display of the touchscreen, wherein altering comprises reducing one of the display around a region of the touch on the touchscreen and the entire display; increasing the touch region; detecting a second touch signal associated with a second touch on the touchscreen, wherein the further second touch takes place within the increased touch region; differentiating, on the basis of the detected second touch signal, be-tween an input touch and a gripping touch, wherein differentiating comprises determining a second touch parameter from the detected second touch signal, and comparing the determined second touch parameter with a corresponding second comparative parameter, the second comparative parameter being more restrictive than the first comparative parameter; and rejecting the second touch signal as an input touch when the second touch signal is attributed to a gripping touch. - View Dependent Claims (14, 15)
