Abstract

A guidance message display control system for displaying a guidance message on terminal equipment, such as multi-media communication terminals. The system maintains and updates a skill level which corresponds to the length of delay occuring before the display of the guidance message. The system awaits a choice selection by a users. If within a predetermined time delay the user has not input a valid selection, then the guidance message is displayed and the skill level is decreased. On the other hand, if a valid selection is made within the predetermined period, then the skill level is increased. Thus, guidance messages are displayed based upon user skill. That is, the messages appear for the unskilled user, but only appear as needed for the skilled user.

Claims

1. A display control unit of a guidance message display control system in terminal equipment for displaying a guidance message, the guidance message display control system also including an input unit, a display unit and a storage memory containing coordinate and status control tables, said display control unit comprising:

input data analyzing means, operatively connected to the input unit, for analyzing input data corresponding to an input operation based on the coordinate control table stored in the storage memory;

status control means, operatively connected to said input data analyzing means, for controlling display timing of the display unit based on the status control table stored in the storage memory;

timer means, operatively connected to said status control means, for counting an elapsed time and for setting a guidance display interval at every input operation, the guidance display interval corresponding to a skill level;

skill control means, operatively connected to said status control means, for controlling the skill level by increasing or decreasing the skill level at each input operation based on the elapsed time, the guidance display interval and correctness of the input operation, through a skill control table stored in the storage memory; and

display control means, operatively connected between said status control means and the display unit, for controlling a display status of the guidance message on the display unit,

wherein said status control means sends a request for the guidance display interval, prior to displaying the guidance message, to said skill control means, sends a command to set the guidance display interval given by said skill control means to said timer means, sends a request for an increment of the skill level to said skill control means when the input operation is correct, and sends a request for a decrement of the skill level to said skill control means when the input operation is incorrect.

2. A display control unit as claimed in claim 1, wherein said skill control means increases the skill level based on the skill control table when receiving an increment request, decreases the skill level based on the skill control table when receiving a decrement request, informs said status control means of a first guidance display interval based on said skill control means when receiving the request for the guidance display interval prior to displaying the guidance message, informs said status control means of a second guidance display interval when receiving a request for the guidance message on the display, and informs said status control means of the guidance message when receiving the request for the guidance message.

3. A display control unit as claimed in claim 2, wherein the first guidance display interval is determined based upon a learning curve and the skill level in the skill control table.

4. A display control unit as claimed in claim 2, wherein the second guidance display interval is determined by multiplying a time for reading one character by a number of characters displayed.

5. A display control unit as claimed in claim 2, wherein the control of the display timing in said status control means and said display control means is performed for the same guidance message.

6. A display control unit as claimed in claim 2, wherein the control of the display timing in said status control means and said display control means is performed for different guidance messages in accordance with the display status of the display unit.

7. A display control unit as claimed in claim 1,

wherein said timer means comprises

a first timer, having a set time, for counting a key-in time elapsed from a key-in operation;

and

a second timer, having a set time, for counting a read time from the display of the guidance message until a next key-in operation, and

wherein the display timing of the guidance message is adjusted by controlling the set time of said first timer in response to the key-in time elapsed from the key-in operation, and the display timing of a next guidance message is adjusted by controlling the set time of said first timer in response to the read time elapsed from the display of the guidance message until the next key-in operation.

8. A display control unit as claimed in claim 7, wherein said first timer counts the time elapsed between key-in operations, when the time elapsed reaches the guidance display interval, said display control means commands the display of the guidance message, said first timer sets the guidance display interval for a next display of the guidance message as smaller than the guidance display interval previously set, and said second timer sets the time interval from the key-in operation until a guidance message display as shorter than the time elapsed.

9. A display control unit as claimed in claim 7, wherein the guidance display interval of said first timer is set to a larger value when the next key-in operation is performed before the count in said first timer is finished, and the guidance display interval from the next key-in operation to the guidance message display is made shorter.

10. A display control unit as claimed in claim 7, wherein the guidance display interval of said first timer is set to a large value when the key-in operation is performed before the count of the read time by said second timer reaches a predetermined value after the display of the guidance message, and the guidance display interval for the next key-in operation to the display of the guidance message remains the same as before the key-in operation.

11. A display control unit as claimed in claim 7, wherein the display timing is set faster when the key-in operation is performed after a count of the predetermined value in said second timer is completed.

12. A display control unit as claimed in claim 7, wherein said first and second timers are set at every input operation, and the display of each guidance message is controlled by a corresponding said first and second timer.

13. A display control unit as claimed in claim 7, wherein said second timer counts a time determined by a number of characters displayed on the display unit.

14. A display control unit as claimed in claim 7, wherein the guidance message is displayed when said second timer finishes a count of the timer value.

15. A display control unit as claimed in claim 7, wherein the guidance message is erased when a key-in operation is performed after displaying the guidance message.
