Abstract

A system and method are provided wherein a user of an interconnected computer system can identify a specific piece of data and then access this data from another computer in the network. This is extremely useful since it is often desirable for data to be capable of being displayed and manipulated from another system during meetings, discussions and the like. The user who wishes to transfer a file to another system simply points an untethered stylus to a representation of a file, such as a filename, icon, or the like and then selects the file to be transferred. The user then carries the stylus to a remote interconnected computer and points the stylus at the remote computer which verifies the identity of the stylus and obtains a path to the selected file. The data file is then transferred from the user'"'"'s computer to the remote computer through the network.

Claims

1. A method of transferring data between interconnected data processing systems, the method comprising the steps of:

assigning a user to a portable stylus which contains an identification of the user that is detectable by each of the data processing systems;

selecting, with said portable stylus, data from a first one of the data processing systems for transfer to an unidentified one of the data processing systems;

detecting the identification at a second one of the data processing systems via the portable stylus; and

transferring, in response to the detection of the identification, the selected data to the second data processing system.

2. The method of claim 1 wherein said step of selecting includes the step of:

creating a table entry including an identification code of the portable stylus, an identification of the first data processing system, and the name of the selected data.

3. The method of claim 2 wherein the step of transferring includes the steps of:

obtaining, in response to detecting the identification, the table entry from the first data processing system;

determining the location of the selected data using the table entry; and

transferring the selected data to the second data processing system.

4. In a network of computers, a method of providing control over a computer program, executing on a first one of the computers, with a second one of the computers, the method comprising the steps of:

assigning a user to a portable stylus which contains an identification of the user that is detectable by each of the data processing systems;

selecting, with the portable stylus, the computer program for control thereof by an unidentified one of the computers;

detecting the identification at a second one of the computers via the portable stylus; and

linking, in response to detecting the identification, the second computer to the first computer, thereby providing control of the computer program to the second computer.

5. The method of claim 4 wherein the step of selecting includes the step of:

creating a table entry including an identification of the portable stylus, an identification of the first computer, and the name of the computer program.

6. The method of claim 5 wherein the step of linking includes the steps of:

obtaining, in response to detecting the identification, the table entry from the first computer;

determining the location of the computer program using the table entry; and

linking the second computer to the first computer, thereby providing control over said computer program.

7. An apparatus for transferring data between interconnected data processing systems, the apparatus comprising:

means for assigning a user to a portable stylus which contains an identification of the user that is detectable by each of the data processing systems;

means for selecting, with the portable stylus, data from a first one of the data processing systems for transfer to an unidentified one of the data processing systems;

means for detecting the identification at a second one of the data processing systems via the portable stylus; and

means for transferring, in response to the identification, the selected data to the second data processing system.

8. The apparatus of claim 7 wherein said means for selecting includes:

means for creating, in response to detecting the identification, a table entry including an identification code of the portable stylus, an identification of said first data processing system, and the name of the selected data.

9. The apparatus of claim 8 wherein the means for transferring includes:

means for obtaining, in response to detecting the identification, the table entry from the first data processing system;

means for determining the location of the selected data using the table entry; and

means for transferring the selected data to the second data processing system.

10. The apparatus of claim 9 wherein the means for selecting includes:

means for creating a table entry including an identification of the portable stylus, an identification of the first computer, and the name of the computer program.

11. The apparatus of claim 10 wherein the means for linking includes:

means for obtaining, in response to detecting the identification, the table entry from the first computer;

means for determining the location of the selected data using the table entry; and

means for linking the second computer to the first computer, thereby providing control over the computer program.

12. In a network of computers, an apparatus for providing control over a computer program, executing on a first one of said computers, with a second one of said computers, said apparatus comprising:

means for assigning a user to a portable stylus which contains an identification of the user that is detectable by each of the data processing systems;

means for selecting, with the portable stylus, the computer program for control thereof by an unidentified one of the computers;

means for detecting the identification at a second one of the computers via the portable stylus; and

means for linking, in response to detecting the identification, the second computer to the first computer, thereby providing control of the computer program to the second computer.
