Abstract: A method performed by a device having a touch-sensitive panel includes detecting touch coordinates of a touch on the touch-sensitive panel and measuring a current though at least a portion of the touch-sensitive panel. The method further includes comparing the measured current with a threshold current and identifying the touch as a multiple touch based on the comparison of the measured current with a threshold current. The method may also include generating a command signal corresponding to the multiple touch.

Abstract: In an embodiment, a mobile electronic device is provided which is equipped with one or more pressure-sensitive areas. In an embodiment, pressure or force acting on said pressure-sensitive areas is converted to an electric signal and evaluated by a control unit to control functions of the mobile electronic device.

Abstract: A passive pointer device, in shape of a stylus, for being used in conjunction with a capacitance sensitive touch screen for pointing, writing, drawing or others on the touch screen.

Abstract: A method performed by a device having a touch-sensitive display may include displaying an image on the touch-sensitive display; detecting a touch on the touch-sensitive display; determining a type of the touch; associating a location of the touch with the image displayed on the touch-sensitive display; and generating a command signal based on the type of touch and the location of the touch on the touch-sensitive display.

Abstract: An electronic device includes a touch panel interface that receives information from a touch panel indicating sensed movement between two user touch positions on the touch panel, and identifies that at least two time-overlapping touches have occurred at different positions on the touch panel in response to at least a threshold speed of the movement. The touch panel interface identifies that at least two time-overlapping touches have occurred on the touch panel in response to a speed of movement from one touch coordinate position to another exceeding the threshold speed. The touch panel interface also identifies that a single touch has occurred with subsequent sliding while pressed against the touch panel from one touch coordinate position to another in response to the movement having less than the threshold speed.

Abstract: The invention relates to an input device comprising a first conductive layer, a second conductive layer, and a piezoelectric material layer arranged in between the first conductive layer and the second conductive layer.

Abstract: A portable communication device is equipped with a touch input display that includes a source of non-visible light integrated within touch input display and a plurality of photodetectors integrated within the touch input display, wherein the photodetectors are configured to detect non-visible light. The portable communication device is configured to detect touch of the display without additional touch-sensitive layers disposed over the display, as well as to detect touch in dark environments and/or with dark images or backgrounds on the display.
