Abstract: The invention provides a digital painting apparatus and method that captures the natural textures in physical painting tools. It is comprised of a plurality of sensors below a painting surface and a light source arranged such that reflective objects near the sensors are imaged, with the nearer parts of the objects forming brighter parts of those images.

Abstract: Alternating touchscreen conductors in each layer of a touchscreen display are connected to separate touchscreen controllers. Each controller completely and separately resolves a location anywhere on the display so that a failure of either controller, or the failure of conductors connected to either controller, do not degrade touchscreen usability. Conductors in separate layers, connected to separate controllers may be isolated via insulators to prevent undesirable shorts. Conductors are shaped to minimize the area covered by insulators and maximize the area of useful conductor overlap.

Abstract: A method of generating symbols from a chording keyboard is described. A unique feature of this method is accepting a sequence of chords from the keyboard without either an intervening chord or a requirement that all keys be released between chords. Another unique feature is that the chord map is independent of chords before or after a particular chord, for a particular symbol. That is, a user need only memorize one chord for each symbol, and then may transition directly from exactly that chord to any other chord. There are no special transition requirements. The number of keys on a keyboard for this method may be 4 to 10, inclusive. Such a keyboard may be operated with one hand. Specific attributes of embodiments or chord tables are described.
