Abstract

The present invention describes a method for superimposing prespecified locational, environmental, and contextual controls on user interactions, including interactions of mobile users, with computational resources. A system is described for electronically monitoring contextual information concerning users and machines, including state and locational information including proximity. Interaction policies, including user specified interaction policies, may be registered on an identifiable address path. Methods are described for detecting, selecting and controlling computercontrolled devices, based on the proximity of the device to the user, the current context of the user, the location of other nearby users and devices, and the current state of the devices. Temporary transfer of control, including exclusive control, of particular computers and computer controlled devices to individual users based on the context and environment in proximity to those computing devices is also described.

Claims

1. A method for superimposing prespecified locational, environmental, and contextual controls on user interactions, including interactions of mobile users, with computational resources of a distributed computer system for performing a multiplicity of operations and with processes running on equipment residing on said system, each device of the distributed computer system having a location and at least one allowable operation, the method comprising the steps of:

registering interaction policies, including user specified interaction policies, on an identifiable address path;

registering user and equipment locations, including dynamically updated indications of the locations of mobile users;

registering interaction requests, each interaction request including a requested operation;

identifying locational and contextual attributes of each of said interaction requests by reference to contextual information, including registered locations;

for each interaction request, identifying a device having locational attributes consistent with the locational attributes of the interaction request and an allowable operation consistent with the requested operation of the interaction request;

granting interaction requests that have locational and contextual attributes that are consistent with said interaction policies and for which a device has been identified whose allowable operation is consistent with the requested operation; and

denying interaction requests that have locational or contextual attributes that are inconsistent with said interaction policies.

2. The method of claim 1, wherein said user specified interaction policies include specification of priority of interaction necessary to grant an interaction request.

3. The method of claim 1, wherein said user specified interaction policies include specification of acceptable resource types for use to grant requested interactions of particular privacy levels.

4. The method of claim 3, wherein said interaction request is granted when said contextual attributes include coincidence with other users consistent with said particular privacy levels.

5. The method of claim 1, wherein said registered interaction requests may include type definitions for requested resources, coincidence with other users, and specification relative to location.

6. The method of claim 1, wherein said contextual attributes may include coincidence with other users.
