Abstract

Performance of a device manipulated by a user is controlled essentially by at least one control module having an input-output relationship regulated by control parameters. Optimization of overall characteristics of the performance can be conducted by (a) preselecting values of the control parameters and activating the device; (b) changing values of the control parameters within predetermined ranges under predetermined coding rules; (c) evaluating the performance of the device based on signals indicative of the performance; (d) displaying to the user the evaluation outcome in the form of intuitively recognizable symbols which are preselected to represent various evaluation outcomes; and (e) selecting values of the control parameters based on the selected symbol(s) by the user. By repeating steps (b) through (e) while operating the device, the at least one control module is optimized.

Claims

1. A method for controlling performance of a device manipulated by a user, which performance is controlled essentially by at least one control module having an input-output relationship regulated by control parameters, said method comprising the steps of:

(a) preselecting values of the control paralmeters and activating the device;

(b) on-line changing values of the control parameters within predetermined ranges under predetermined coding rules;

(c) on-line evaluating the performance of the device based on signals indicative of the performance;

(d) on-line displaying to the user the evaluation outcome in the form of single picture symbols which is preselected to intuitively represent evaluation outcomes;

(e) on-line repeating steps (b) through (d), thereby providing multiple picture symbols to the user for selection;

(f) on-line selecting values of the control parameters based on the selected symbol(s) by the user; and

(g) repeating steps (e) through (f) while operating the device until desired performance of the device is demonstrated, wherein the at least one control module is optimized.

2. The method according to claim 1, wherein, in step (a), the values of the control parameters are preselected by the user using a picture symbols which is preselected to intuitively represent the control parameters'"'"' outcome.

3. The method according to claim 1, wherein the display of the symbols changes in accordance with the number of repeating cycles of steps (b) through (d).

4. The method according to claim 1, wherein the display is indicated by visual signals.

5. The method according to claim 1, wherein step (b) is conducted using heuristic processes programmed to change values of the control parameters toward a direction of obtaining rewards which are defined by the result of selection by the user in step (e).

6. The method according to claim 1, wherein the control module comprises at least one neural network, the input-output relationship of which is regulated by coupling coefficients used as the control parameters.

7. The method according to claim 1, wherein the device'"'"'s performance is characterized by at least two elements, and each control module is related to a different characteristic element.

8. The method according to claim 7, wherein optimization by steps (a) through (f) is conducted on each control module in repetitive sequence.

9. The method according to claim 1, wherein the device is a control module for controlling another device.

10. The method according to claim 1, wherein the device is a motor.

11. The method according to claim 1, wherein in step (e), the multiple picture symbols are displayed as options, and in step (f), the selected potion and non-selected options are displayed, thereby showing to the user a decision tree.

12. The method according to claim 11, wherein the non-selected options are displayed in smaller size than the selected option.

13. The method according to claim 1, wherein in step (e), the multiple picture symbols are pictures of different species of fish.

14. The method according to claim 1, wherein in step (e), the multiple picture symbols are pictures of fishes having different body types.

15. A method for controlling performance of a device manipulated by a user, which performance is controlled essentially by at least one control module having an input-output relationship regulated by control parameters, said method comprising the steps of:

(a) preselecting values of the control parameters and activating the device;

(b) on-line changing values of the control parameters within predetermined ranges under predetermined coding rules;

(c) on-line evaluating the performance of the device based on signals indicative of the performance;

(d) on-line displaying to the user the evaluation outcome in the form of symbols which are pre-selected from the group consisting of fish to represent various evaluation outcomes;

(e) on-line selecting values of the control parameters based on the selected symbol(s) by the user; and

(f) repeating steps (b) through (e) while operating the device until desired performance of the device is demonstrated, wherein the at least one control module is optimized.
