VISION-GUIDED MODEL-BASED POINT-AND-CLICK INTERFACE FOR A WIRELESS HANDHELD DEVICE

摘要

Aspects of the invention overcome the problem of establishing communications with devices for which the communication protocol is unknown. One aspect of the invention involves the use of a discovery registration in which a portable device is provided with information describing the physical appearance characteristics figure 2) of objects or devices that may be used to identify an object of interest. Another aspect of the invention involves the use of sensing techniques for establishing the identity of an object for which more information is sought by comparing the sensed physical characteristics of an object with data describing the physical characteristics of the objects located within an environment of the network. Aspects of the invention further involve associating the information describing the physical characteristics of objects or devices with additional information regarding the object, which may include the communication protocol for the device or object with which communication is desired.
