Abstract: Encoding data in a pattern of symbols on a surface. A processor separates an ordered sequence of digits representative of the encoded data into a plurality of sequential windows. Each of the sequential windows includes a partial sequence of the ordered sequence of digits. The processor further transforms the partial sequence included in each sequential window into a series of digits. A symbol is arranged within a plurality of surface windows on the surface. Each surface window corresponds to one of the sequential windows. The symbol is positioned within each surface window based on one of the transformed series of digits. And the position of the symbol within the surface window is indicative of the encoded data.

Abstract: In a computer system, a touch sensitive input device having touch sensitive auxiliary controls system can be used to anticipate a user's action. When a user's hand approaches a touch sensitive input device, feedback can be displayed on a display screen. A user can receive feedback without activating the input device. The feedback may take the form of status information related to the feature controlled by the input device and can vary depending upon the application open. Likewise, when the hand of a user is moved away from the touch sensitive input device, the feedback brought on by sensing the user's hand may disappear.
