摘要： This invention describes a universal pointing and interacting (UPI) device that is configured to interact with objects of interest, where interacting means identifying objects of interest pointed at by the UPI device, providing information about such objects and activating such objects by the user of the UPI device. Objects of interest are geographical, topographical, urban, commercial and other types of objects in the surroundings of the user of the UPI device, that their features, such as their location parameters, visual descriptions and other useful information about these objects of interest, are obtainable from accessible databases. Objects of interest may also be moving objects that estimate their location parameters and make that information public, or may be virtual objects that are generated with known location parameters in the surroundings of the user of the UPI device. The UPI device, supported by a handheld device for its operation, operates to identify an object of interest that is pointed at, based on the obtained location parameters and visual description of that object. Based on the identification of the object of interest, output about that object is provided to the user of the UPI device by the UPI device itself or by the handheld device. Some of the identified objects of interest may execute an action and such objects of interest may be activated by commands from the user of the UPI device. Objects of interest may also be screens, such as computer, TV or presentation screen, which may be activated by the UPI device similarly to the operation of a mouse, stylus or remote control unit.
