Claim Text:
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.
