Optical Stylus Interaction

摘要: Optical stylus interaction techniques are described. In an implementation, a display of computing device includes optical sensors capable detecting images projected by stylus. A may include projection system to project various used convey information that be interpreted the device. Based on recognition different images, context for ascertained and corresponding operations performed This resolving spatial position relative as well movement defines stylus-based gestures. addition, environment enables writing mode emulates natural mapping projectable changes in pressure applied when contact with display.
