Abstract

A method of simultaneously executing one or more computer application programs in one or more host computer system under the control of a second computer system, where the second computer system performs operations on data and instructions and the host computer systems generates presentation information based on the application programs, involves establishing selected parameters in the host computer presentation information, interpreting selected portions of the host computer system'"'"'s presentation information, providing the interpreted selected portions of the host computer system'"'"'s presentation information as input to a computer program resident in the second computer system, examining the host computer system presentation information at the second computer system to detect the presence therein of one or more the selected parameters, continuing operation of the second computer system during the examining for the selected parameters, and generating an indication to the second computer system of the detection of one or more of the selected parameters in the host computer system presentation information.

Claims

1. A method of simultaneously executing one or more computer application programs in one or more host computer systems under the control of a second computer system, where said computer application programs may be dissimilar to each other, and said host computer systems may be dissimilar to each other, said second computer system including a human user interface and performing operations on data and instructions, said host computer systems generating presentation information based on said application programs, said method comprising the steps of:

establishing a plurality of relevant selected parameters in said host computer presentation information;

said relevant selected parameters having a variable time of occurrence and context in said presentation information;

providing said relevant selected portions of said host computer system'"'"'s presentation information as input to a computer program resident in said second computer system;

examining and interpreting selected portions of said host computer system presentation information, in said application programs being executed at said second computer system to detect the presence therein of one or more of said selected parameters;

said examination of said host computer system presentation information being dependent on the time of occurrence and the context of said selected parameters in said host computer presentation information;

continuing said operation of said second computer system during said examining for said selected parameters; and

generating an indication to said second computer system of the detection of one or more of said relevant selected parameters in said host computer system presentation information.

2. A method of simultaneously executing one or more computer application programs in one or more host computer systems under the control of a second computer system, where said computer application programs may be dissimilar to each other, and said host computer systems may be dissimilar to each other, said second computer system including a human user interface and performing operations on data and instructions, said host computer systems generating presentation information based on said application programs, said method comprising the steps of:

establishing a plurality of relevant selected parameters in said host computer presentation information;

said relevant selected parameters having a variable time of occurrence and context in said presentation information;

interpreting selected portions of said host computer system'"'"'s presentation information, in said application programs being executed;

providing said interpreted selected portions of said host computer system'"'"'s presentation information as input to a computer program resident in said second computer system;

examining said host computer presentation information at said second computer system to detect the presence therein of one or more said selected parameters;

said examination of said host computer system presentation information being dependent on the time of occurrence and the context of said selected parameters in said host computer presentation information; and

generating an indication to said second computer system of the detection of one or more of said relevant selected parameters in said host computer system presentation information.

3. A method in accordance with claim 2 including the step of:

generating a user'"'"'s interactions at said user interface to at least some of said interpreted selected portions of said host computer system'"'"'s presentation information.

4. A method in accordance with claim 2 in which said examining for a given selected parameter continues for only a predetermined length of time.

5. A method in accordance with claim 4 including the step of generating at said user interface an indication of the lack of the detection of a selected parameter during said predetermined length of time.

6. A method in accordance with claim 2 in which any one of said selected parameters can be detected only once in said presentation information.

7. A method in accordance with claim 3 including the step of:

providing said user'"'"'s interactions at said user interface as input to said resident computer program in said second computer system.

8. A method in accordance with claim 7 including the step of:

generating information from said resident computer program in response to said user'"'"'s interactions.

9. A method in accordance with claim 8 including the step of:

transmitting said generated information to said host computer system.

10. A method in accordance with claim 8 in which at least one of said selected parameters is based on the position of said parameter in said presentation information.

11. A method in accordance with claim 9 in which said presentation information is arranged in rows and columns.

12. A method in accordance with claim 11 in which said selected parameter is located in a given one of said rows.

13. A method in accordance with claim 11 in which said selected parameter may be located in any of said rows and any of said columns.

14. A method in accordance with claim 11 in which said selected parameter is located in a given one of said columns.

15. A method in accordance with claim 12 in which said selected parameter can be detected only once in any given one of said rows.

16. A method in accordance with claim 11 in which said selected parameter is located in a given one of said rows and a given one of said columns.
