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.

International Classification:

G06F 9/45
G06F 9/48

Abstract:

An aspect includes optimizing an application workflow. The optimizing includes characterizing the application workflow by determining at least one baseline metric related to an operational control knob of an embedded system processor. The application workflow performs a real-time computational task encountered by at least one mobile embedded system of a wirelessly connected cluster of systems supported by a server system. The optimizing of the application workflow further includes performing an optimization operation on the at least one baseline metric of the application workflow while satisfying at least one runtime constraint. An annotated workflow that is the result of performing the optimization operation is output.

Abstract:

Global and local light detection techniques in optical sensor systems are described. In one or more implementations, a global lighting value is generated that describes a global lighting level for a plurality of optical sensors based on a plurality of inputs received from the plurality of optical sensors. An illumination map is generated that describes local lighting conditions of respective ones of the plurality of optical sensors based on the plurality of inputs received from the plurality of optical sensors. Object detection is performed using an image captured using the plurality of optical sensors along with the global lighting value and the illumination map.
