Abstract:
PROBLEM TO BE SOLVED: To provide a method, apparatus and system for tracking movement of a device. SOLUTION: The method includes steps of implementing a first tracking subsystem for tracking positions of a device against a surface, determining whether to implement a second tracking subsystem for tracking positions of the device against the surface, capturing data corresponding to a location on the surface and determining a position of the device against the surface based on the captured data. The position of the device can then be transmitted to a host computer and used in an application program. The first and second tracking subsystems may be a relative and an absolute tracking subsystem respectively. COPYRIGHT: (C)2006,JPO&NCIPI
Abstract:
Embodiments include a smart personal gateway device (SPGD) that augments the capabilities of smart personal devices (SPDs) connected in a personal area network (PAN). The SPGD implements services for the SPDs using computing resources of the SPGD. In some embodiments, the SPGD provides carrier-grade voice services to SPDs lacking hardware to support such services (e.g., SPDs supporting Wi-Fi only).
Abstract:
Light guide techniques are described. In one or more implementations, an apparatus includes a housing, a light guide supported by the housing, a light engine disposed within the housing and optically coupled to the light guide, and one or more modules disposed within the housing and implemented at least partially in hardware. The one or more modules are configured to cause the light engine to output a user interface for display using the light guide along an image plane focused at infinity.
