Optical Stylus Interaction
First Claim
1. A computing device comprising:
- a display device including one or more optical sensors configured to detect images projected onto a surface of the display device by a stylus;
an image decoder module configured to;
decode a detected image to ascertain a context for interaction with the computing device using the stylus; and
cause performance of one or more actions by the computing device that are associated with the ascertained context.

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

9. A method implemented by one or more modules at least partially in hardware of a computing device, the method comprising:
-
detecting one or more images projected onto a display device associated with the computing device using a stylus; decoding the one or more projected images to resolve a spatial position of the stylus relative to the display device; and performing one or more actions corresponding to the spatial position that is resolved by the decoding of the one or more images. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17)

18. A stylus comprising:
-
a projection system; one or more image elements embodying image information for corresponding images to enable projection of the images via the projection system to a target computing device; and a mode manager module configured to cause the projection system to project different images using the image information embodied by the one or more image elements in response to manipulation of the stylus to convey interaction information for the stylus optically for decoding by the target computing device, the different projected images interpretable by the target computing device to recognize one or more of a spatial position of the stylus, an activated mode for the stylus, or a gesture produced by manipulation of the stylus. - View Dependent Claims (19, 20)
