Switching an application, user and security context based on device orientation
A computer is adapted for changing one or more of the application, security, or user contexts based on the orientation of a component, such as a monitor. Changing the context responsive to the reorientation allows two or more users to use the same hardware to complete a transaction requiring at least two perspectives, for example, buyer and seller. In the background, transaction end points may be changed as well as establishment of a secure channel for supporting confidentiality of a user and their personal information. The computer so equipped may be applicable to many situations involving two parties, such as hospitals, personnel/human relations, banking, government benefits, and retail.
1. A computer supporting a plurality of user contexts comprising:
a component adapted for use in a plurality of orientations;
a memory for storing data corresponding to a plurality of contexts, each of the plurality of user contexts corresponding to a respective unique user;
a sensor for reporting an orientation of the component; and
a processing unit coupled to the sensor, wherein the processing unit selects a first one of the plurality of user contexts from the plurality of user contexts responsive to a first orientation of the component and a second one of the plurality of user contexts responsive to a second orientation of the component.
2. The computer of claim 1 , wherein both the first and second user context comprises one of a human user identity and a function-defined user identity.
3. The computer of claim 2 , wherein the human user identity comprises one of a customer, a clerk, a supervisor, a data entry person, a client, and an administrator.
4. The computer of claim 1 , wherein the processing unit interprets the sensor data to determine a first user zone and a second user zone for the component.
5. The computer of claim 4 , wherein the processing unit interprets the sensor data to determine a transition zone between the first and second user zones.
6. The computer of claim 1 , wherein the component is a display.
7. A computer-readable memory device adapted to store executable instructions comprising:
a first module for monitoring the orientation of a display logically coupled to a computer; and
a second module for changing between a first security context to a second security context of the computer responsive to a change in the orientation of the display.
8. The computer-readable memory device of claim 7 , adapted to store executable instructions wherein the security context comprises at least one of a secure communication channel for communicating with a remote process and a digitally signed application presenting a user interface.
9. The computer-readable memory device of claim 7 , adapted to store executable instructions further comprising:
a third module for activating a user context responsive to a change in the orientation of the display of the computer.
10. The computer-readable memory device of claim 7 , adapted to store executable instructions further comprising:
a fourth module for activating an application responsive to a change in the orientation of the display of the computer.
11. The computer-readable memory device of claim 7 , adapted to store executable instructions wherein the second module further comprises executable instructions for establishing a secure communication channel between the computer and a server.
12. The computer-readable memory device of claim 7 , adapted to store executable instructions wherein the application is one of a data entry application and an approval application.
13. A method of adapting a computer for use in multiple contexts comprising:
providing a component of the computer adapted for use in a plurality of orientations;
associating an operating environment with the each of the plurality of orientations of the component;
determining a current orientation from the plurality of orientations of the component of the computer;
selecting the operating environment associated with the current orientation of the component; and
establishing a first operating environment associated with a data entry context when the component is in a first orientation of the plurality of orientations and a second operating environment associated with an approval context when the component is in a second orientation of the plurality of orientations.
14. The method of claim 13 , wherein the determining the current orientation of the component comprises monitoring data from a sensor, the data corresponding to a position of the component.
15. The method of claim 13 , wherein the data entry context comprises a first environment for a first user and the approval context comprises a second environment for a second user, each of the operating environments comprising an application context and a security context.
16. The method of claim 13 , wherein the operating environment comprises a user identity, the user identity comprising one of a human user and a function-defined user.
17. The method of claim 13 , wherein establishing the first and second operating environments comprises establishing a data entry user when establishing the first operating environment and establishing an authorization user when establishing the second operating environment.
18. The method of claim 17 , wherein establishing the second operating environment comprises performing an implicit login process.
