Abstract

A computing system includes an access prevention module that selectively locks use of one or more system resources of that computing system. A vision-based input module is configured to recognize a data-encoded tag while the access prevention module locks use of the one or more system resources. A lookup module is configured to receive a usage profile identified by the data-encoded tag, and a login module is configured to unlock use of some to all of the one or more system resources in accordance with terms of the usage profile.

Claims

1. A computing system, comprising:

an access prevention module to selectively lock use of one or more system resources;

a vision-based input module configured to recognize a data-encoded tag while the access prevention module locks use of the one or more system resources;

a lookup module to receive a usage profile identified by the data-encoded tag;

a login module to unlock use of some to all of the one or more system resources in accordance with terms of the usage profile.

2. The computing system of claim 1, where the login module unlocks use of some to all of the one or more system resources up to a maximum duration specified by the usage profile.

3. The computing system of claim 1, where the login module unlocks use of some to all of the one or more system resources during a time period specified by the usage profile.

4. The computing system of claim 1, where the lookup module sends an identifier derived from the data-encoded tag to a remotely-located usage profile server and receives the usage profile from the remotely-located usage profile server.

5. The computing system of claim 1, further comprising a usage profile database, where the lookup module receives the usage profile from the usage profile database based on an identifier derived from the data-encoded tag.

6. The computing system of claim 1, where the login module automatically sets an active-user as a user identified by the usage profile.

7. The computing system of claim 1, further comprising a shell module, where the login module automatically sets the shell module in a simple-use mode of operation specified by the usage profile.

8. The computing system of claim 1, further comprising one or more digital cameras to capture an image of the data-encoded tag and pass the image to the vision-based input.

9. The computing system of claim 8, further comprising a rear-projector and a rear-projection display surface, where the one or more digital cameras are configured to capture the image of the data-encoded tag when the data-encoded tag is positioned on the rear-projection display surface.

10. The computing system of claim 1, further comprising a mobile telephone module, where the access prevention module selectively locks use of the mobile telephone module and the login module unlocks use of the mobile telephone module in accordance with terms of the usage profile.

11. The computing system of claim 1, further comprising a communications module, where the access prevention module selectively locks use of the communications module and the login module unlocks use of the communications module in accordance with terms of the usage profile.

12. The computing system of claim 1, further comprising a game module, where the access prevention module selectively locks use of the game module and the login module unlocks use of the game module in accordance with terms of the usage profile.

13. A method of rationing computing access, the method comprising:

specifying a computer usage allowance;

sending the computer usage allowance to a remotely-located usage profile server;

saving the computer usage allowance as part of a usage profile;

tying the usage profile to a data-encoded tag;

outputting a computer-readable token including the data-encoded tag;

selectively locking use of one or more system resources;

recognizing the data-encoded tag while the one or more system resources are locked;

receiving the usage profile tied to the data-encoded tag; and

unlocking use of some to all of the one or more system resources in accordance with terms of the computer usage allowance specified by the usage profile.

14. The method of claim 13, where outputting the computer-readable token includes printing the data-encoded tag.

15. The method of claim 13, where recognizing the data-encoded tag includes capturing an image of the data-encoded tag with one or more digital cameras.

16. The method of claim 13, where unlocking use of some to all of the one or more system resources includes unlocking use of some to all of the one or more system resources during a time period specified by the usage profile.

17. The method of claim 13, where unlocking use of some to all of the one or more system resources includes unlocking use of some to all of the one or more system resources up to a maximum duration specified by the usage profile.

18. The method of claim 13, further comprising automatically setting a shell module in a simple-use mode of operation specified by the usage profile.

19. The method of claim 13, further comprising automatically setting an active-user as a user identified by the usage profile.

20. A data-holding subsystem holding instructions executable by a logic subsystem to:

selectively lock use of one or system resources;

recognize a visually-input data-encoded tag while use of the one or more system resources is locked;

receive a usage profile identified by the data-encoded tag; and

unlock use of some to all of the one or more system resources in accordance with terms of the usage profile.
