Abstract: A method and system for human computer interaction using hand gestures is presented. The system permits a person to precisely control a computer system without wearing an instrumented glove or any other tracking device. In one embodiment, two cameras observe and record images of a user's hands. The hand images are processed by querying a database relating hand image features to the 3D configuration of the hands and fingers (i.e. the 3D hand poses). The 3D hand poses are interpreted as gestures. Each gesture can be interpreted as a command by the computer system. Uses for such a system include, but are not limited to, computer aided design for architecture, mechanical engineering and scientific visualization. Computer-generated 3D virtual objects can be efficiently explored, modeled and assembled using direct 3D manipulation by the user's hands.

Abstract: A remotely provisioned proxy within a wireless/mobile phone that proxies a wireless communication path between a disconnected piconet (e.g., BLUETOOTH™) device and a network resource such as a universal resource locator (URL) via a mating mobile phone. Thus, an application proxy module embodied within the mobile phone provides managed access of a piconet device connected to the mating mobile phone to remote services. A disconnected piconet device uses the full data bandwidth available to a wireless phone, without the need for the disconnected piconet device to include its own separate wireless front end, or to require use of a modem within the mobile phone. Thus, using a mobile phone with application proxy, the user need not pay for the luxury of a tethered data plan.
