Abstract: Method and apparatus for displaying a view of an application on a touch-sensitive display include detecting a touch on the touch-sensitive display. When the touch is at a first force, first feedback is provided and a first function is performed. When the touch is at a second force, second feedback is provided and a second function is performed. The first function and the second function are different. The first force and the second force are different.

Abstract: A handheld electronic device having a touchscreen and a method of using a touchscreen of a handheld electronic device are provided.

Abstract: A display screen is capable of having regions having different switching speeds as well as regions that are not switched. One region having a first switching speed may be for colour mode display and the other region having a second switching speed different from the first may be for monochrome mode display. Other regions may be off and not switched. In alternative versions, three or more switched regions may be established on a display screen. For example, a monochrome region may be nested inside a colour region, in which the colour region may be nested between off regions.

Abstract: A method comprises searching in a video stream a first frame and a second frame that each has enough point correspondence with a image model, wherein the first frame is the nearest previous frame prior to a third frame, and the second frame is the nearest subsequent frame to follow the third frame. The method further comprises calculating an interpolation between a first mapping matrix of the first frame and a second mapping matrix of the second frame to obtain a third mapping matrix of the third frame that has insufficient point correspondence with the image model.

Abstract: A method of determining input at a touch-sensitive input surface of a portable electronic device includes detecting a touch event at the touch-sensitive input surface, sampling touch attributes during the touch event, determining an actual touch location and determining at least one shift in touch location based on the touch attributes sampled during the touch event, and determining an input based on the actual touch location and the direction of shift of the touch location.
