Abstract: A method and system in a data-processing system having a touch-sensitive display unit wherein touch-sensitive icons displayed within the touch-sensitive display unit may be calibrated according to physical characteristics associated with a particular user. Touch-sensitive icons are displayed within a touch-sensitive display unit, such that upon activation by a user, the touch-sensitive icons initiate data-processing operations. Thereafter, a user is prompted to enter a particular sequence of data utilizing the touch-sensitive icons. Physical characteristics associated with the user are then analyzed while the user is entering the particular sequence of data utilizing the touch-sensitive icons. Finally, in response to analyzing the physical characteristics, the touch-sensitive icons are configured such that the sensitivity of the touch-sensitive display may be raised or lowered according to the physical characteristics associated with the user. The touch-sensitive icons may be composed of touch-sensitive keys.

Abstract: One embodiment of the writing instrument described herein comprises a pen-like device containing three accelerometers and three gyroscopes. Data from these sensors are processed via an Euler transform. Prior to using the writing instrument, the user holds the writing instrument in multiple predefined positions and sensor readings are taken. The sensor readings are mapped to the corresponding predefined positions. In addition, the sensor readings are compared to expected sensor readings to compensate for environmental variations such as altitude or temperature as well as for the possible tilt of a writing surface. The sensor readings are interpolated to map sensor readings other than those at the predefined positions to other writing instrument positions. When the user writes with the writing instrument, sensor outputs are used to track the writing instrument to define strokes made by the user.

Abstract: This invention is directed to a method and apparatus for producing video signal timing for a display device that has a display format different from the input video format. It also provides a method and apparatus for producing video signal timing in cases where the input video line rate and display output line rates are not the same.

Another aspect of the present invention provides a method and apparatus for synchronizing display output timing to input video timing such that both are locked in terms of frame rate, but skewed in terms of frame phase, in order to accommodate latency incurred by processing of source video data to generate the display video data.
