Abstract
Methods, hardware, and software establish surfaces for graphics processing by setting a position of the capture device fixed on or relative to that surface. A user may hold the device against the surface or through other means. Ambient setting, potentially including the surface itself, is visually captured at the position. Using that position the surface is established—readily known by position, size, shape, etc. within the surroundings. Stable positioning can be determined in any way, using any data. Motion of the device may be known via internal or external sensors, and stable surface touching can be detected with a lack of motion. A user may input when the device is steady. Abutment can be measured from visual input or impact sensors. All such input may determine and/or verify a stable position. Visual input from the stable position may thus be used to establish the surface for graphical processing.
