Abstract: A method (300 or 400) of key press prediction on a touch-based device or an apparatus (501) can entail registering (302, 402) a position of a touch press attempt on an icon among a plurality of icons presented on the touch-base device, calculating (304, 404) a distance from a center of the icon, calculating (306, 406) a psychomotor probability for each icon in the plurality of icons, calculating (312, 408) a linguistic probability for each icon in the plurality of icons, calculating (314, 410) a predictive index for each icon in the plurality of icons based on the psychomotor probability and the linguistic probability, and registering (310,416) as a user selected icon, an icon with one among a highest predictive index (316, 412) or a probability higher than a predetermined absolute value (308).

Abstract: A method (FIG. 1 ) and apparatus (205) for user interface adaptation determines (110) a handedness of a user who is operating the handheld device, and changes (115) physical aspects of at least one touch target of a user touch interface of the handheld device to adapt to the handedness of the user when the handedness of the user is different than a current handedness of user touch interface of the handheld device.

Abstract: A scrolling user interface comprises proportional scrolling responsive to contact in a proportional zone of a scrolling strip and multi-mode scrolling in response to contact in a multi-mode zone of the scrolling strip. Multi-mode scrolling can include proportional scrolling, continuous scrolling, or stepped scrolling.

Abstract: Methods (800, 1000) and a corresponding system (100, 200) are configured for mitigating effects of motion induced variability caused by a user or the environment while the user interacts with a device. One method includes determining whether stabilization of input data is required and if so applying stabilization and outputting or displaying the stabilized data. Another method includes monitoring input data and moving a display element as well as a target element based on the input data.
