CONTEXT SENSITIVE WEB SERVICES

摘要

The context sensitive web services method enables a mobile phone or wireless device to use context inference techniques to sense the user's environment and in response, to provide useful information to the user that is appropriate to the user's perceived environment. The method includes the steps of receiving sensor signals characterizing a current environment of the wireless device; processing the sensor signals with a context inference engine; outputting a current context result from the processing by context inference engine; and providing useful information to the user in response to the current context result. A further aspect of the method provides user control of access by application programs to the user's private data, including private data in a server. Still further, this can also include providing user control of access by application programs in a web server, to the user's private data. Another aspect of the method is providing the current context result to an application program in response to the user control and receiving the useful information from the application program. The invention enables the user to grant access permission to the application program to access the current context result. This can be performed in the user's wireless device or in the network server. The network server can carry out the control of access by application programs in web servers, in response to a user privacy profile received from the user's wireless device.
