Abstract

PURPOSE:To decrease the malfunctions due to misinputs and at the same time to secure the key operating feeling in response to the degree of expertness of an operator, by changing the weighting of the input key according to the accurateness as well an the input speed. CONSTITUTION:A CPU 241 detects the key input given from an input device 230 according to a key input processing program stored in an input processing memory 243a. Then the CPU 241 counts the key inputs (input speed) and the wrong key inputs per unit time in accordance with the detected key input. Based on these count values, the weighting of a weighting processing table 243b is changed. Thus the weighting of the key input is changed in response to the expertness of an operator, i.e., the input speed and the input accurateness. As a result, the system malfunctions due to misinputs can be decreased and at the same time the key operating feeling is secured in response to the expertness of the operator.

It is stored in the boot ROM 242 and is set by a program at the initial time after the power is turned on.

FIG. 3 is a block diagram of the input device 230 and the key manual control section 247.

The input device 230 connects the signal bus 2 to the key human control unit 247.
The key human control unit is composed of a selector circuit 231 connected to the switch 70 and used for extracting a switch-on point, a decoder circuit 232, and a switch matrix 233 connected to the other terminal of the selector circuit 231 and the decoder 232. CPU24 via I10 port of 247

By focusing on the output signal of the processing selector circuit 231 and configuring it to indicate that the switch is on when the output signal is at a high level, the address signal when the output signal is at a high level indicates that the switch is on. It represents an address.

When the CPU 241 detects the high level of the output signal via the key control unit 247, the CPU 241 stores the switch-on address represented by the address signal as input key information in the input data storage memory 243c, and stores the switch-on address represented by the address signal in the input data storage memory 243c. pass it on.

Next, a key manual processing program (stored in the input processing memory 243a) which includes the features of the present invention among the operating programs of the CPU 241 will be explained with reference to FIG.

The key human power processing program is in charge of the overall key human control of this system, and operates constantly at regular intervals.

It serves to pass key input from the outside to another document editing processing program via the input data storage memory 243c.

The key manual processing program is the weighting processing table 24.
Input key extraction processing 110 performed with reference to the weighting information corresponding to each key set in 3b, operator input speed, ie, number of inputs per unit time, and input accuracy, ie r input data correction. An input state detection process 120 that monitors the number of inputs of keys having the "function" and a weighting change process 130 that refers to the monitoring data of the input state detection process 120 and rewrites the weighting process table 243b are performed.

Next, the manual key extraction process 110. The input state detection process 1201 and the weighting change process 130 will be described in detail.

In process 111, a signal from the switch matrix 233 input via the key manual control section 247 is processed to detect whether or not the key is manually operated.

In process 112, if the key force is detected, the process goes to process 113, and if the key force is not detected, the process goes to process 111 again.

In process 113, the key human power detected in process 111 is
It is determined whether or not the detection is continuous by the detection operation of the CPU 241. If the detection is continuous, a counter C(X) indicating how many times the detection is consecutive is updated in step 114, and if it is discontinuous, it is cleared in step 115.

In process 116, information on the weighting of the key corresponding to the key whose key was manually detected in process 111 is referred to from the weighting process table 243b (shown in FIG. 3), and the counter C is
(R).

In process 117, the counter C(X) and the counter C(
R), and if C(X) < C(R), that is, when the number of consecutive key detections has not reached the predetermined value, process 1.
To 11, the standing tachi (C(X)=C(R)) is processed to 11
Move to 8.

In process 118, the key whose input was detected in process 111 is
It is regarded as an input confirmation key, and the input key information of the key is stored in the input data storage memory 243c and passed to another document editing processing program.

Here, the main control device 240 in FIG.
The value of the counter C(R) set with reference to the weighting process table 243b in process 116 determines the key press time required to recognize and confirm the key force applied from the process 116.

Next, the concept of the counter C(R) will be explained in detail with reference to FIGS. 4 and 5.

The switch matrix 233 provided to the input device 230 has a key arrangement as shown in FIG.

The manual keys A group 233A are for character input, and are alphanumeric.

It is equipped with a key for entering kana. Human power key group B 233
The input keys B and C group 233C are for inputting function instructions, and in this embodiment are provided with keys such as "execute", "cancel", and "backward", and are used to control the operation mode of document editing processing performed by the CPU 241. Among these, the human key A group 233A requires a light key touch due to its character input function, and the human key B group 233B is more susceptible to system malfunctions due to incorrect input than the input key C group 233C. When this occurs, if the degree of fatality is set to be high, it is desirable that the manual key B group 233B has a heavier key touch feel than the input key C group 233C.

Weighting processing table 2 set to achieve this
43b is the 0 weighting processing table 243b shown in FIG.
has a one-to-one correspondence with the input key, and weighting information is set according to the type or function of each input key. In this embodiment, the table area 243b (A)
, 243b (B).

243b (C) is the manual key A group 233A.

Weighting information “5” and “12” according to the type of keys of input key B group 233B and input key C group 233C.

"10" is set. Further, if the cycle at which the CPU 241 performs the detection operation for one key switch is To, then each input key is monitored from either the on or off state at intervals of 1 hour T0. Here, by the input key extraction process 110, the manual key A
The input key belonging to group 233A is not recognized as a key input (not determined) unless the input key is kept pressed for (5xTo) time. In other words, the operator cannot receive a response such as a screen display from the system side. Similarly, the input keys belonging to the manual key group B 233B and the input key group C 233C are (12X
T, ) time # (10XTa) If the input key is not pressed continuously for a period of time, the system does not recognize the input key as manual input. This state is shown in FIG. 6, and state F is C
The detection operation timing for one key of the PU 241 is shown, and states A, B, and C are for the manual key A group 233, respectively.
A.

It represents the minimum time required for input from keys belonging to input key group B 233B and input key group C 233C to be recognized as input confirmation.

Further, in this embodiment, a method is adopted in which key detections are counted at the period T0, but the same effect can be obtained by making the period T variable.

As explained above, the fact that the response time of the system after pressing the input key is different gives the operator the feeling that the key touch is heavy or light. In other words, the longer it feels, the heavier it feels, and the shorter it feels, the lighter it feels.

Next, the input state detection processing 120 will be explained.

In the process 121, the number of keys determined to be input confirmed by the input key extraction process 110 is counted by the counter C1(X). That is, C1(X) represents the number of inputs per unit time, and the larger the number, the faster the manual speed.

Processing 122 determines whether or not the input key, which has been recognized as a confirmed input by input key extraction processing 110, has a function to correct the data input immediately before. or the cancel key, and if so, counter Cc
Update (x). In other words, the counter Cc (X) represents the accuracy of the key manual effort, and the smaller it is, the more accurate the manual effort is.

Process 123 is for determining the period of input state detection, and in this embodiment, the period is set as T8, and the period of input state detection is T8.
If T is less than T, the process goes to process 111, and if they are equal, the process goes to process 124.

In the process 124, the boot ROM 2 as shown in FIG.
42 or speed level data 701 set in advance on the program memory 243 and C1(X) set in process 121, select the latest value, and set the speed level index 702 around period T8 to "O". ~ is stored in the speed level storage area 243d as data of "N". In other words, "0" indicates the highest input speed, and "N" indicates the slowest input speed.
”, and if there is no input, it is configured to be N/2.

In the process 125, the boot ROM 2 as shown in FIG.
42 or the accuracy level data 703 set on the program memory 243 and the C set in the process 122.
c(X), selects the most recent value, and stores the accuracy level index 704 per period Tx in the speed level storage area 243e as data of 40'' to 41 NH.

In other words, if it is the most accurate, set it to "N", if it is considered to have the most incorrect inputs, set it to "O", and if there is no input, set it to 'N/'.
The configuration is such that 2″′ is set.

In process 126, the speed level index 702 and accuracy level index 704 set in processes 124 and 125 are read from the speed level storage area 243d and accuracy level storage area 243e, respectively, and the weighting level index 705 in period Tx is The data is stored in the weighting level storage area 243f as data "0" to "N"'.

Here, in this embodiment, 1 weighting level index 705 is calculated from the speed level index 702 and the accuracy level index 704.
We will explain the thinking behind determining the

(1) If the accuracy level index 704 is equal to or greater than the average value (N/2), the speed level index 702 is set as the weighting level index 705.

(n) If the accuracy level index 704 is equal to or less than the average value (N/2), the accuracy level index 704 is set as the weighting level index 705.

With this method, for operators who make accurate inputs, the weight of the key touch is adjusted according to the input speed, and for operators who often make incorrect inputs, the weight of the key touch is adjusted according to the degree of incorrect input. It can make you feel heavy. In addition, the speed level data 701 and accuracy level data 703 serve as comparison standards, and are based on the purpose, size, and
Optimal data can be set according to the operation mode.

Next, the weighting change processing 130 will be explained.

In process 131, the weighting level index 705 determined in the process 126 is stored in the weighting level storage area 243.
Preparations for rewriting the 1-weighting processing table 243b are made with reference to f.

In the process 132, as shown in FIG. 8, a weighting data group 8 set in advance on the boot ROM 242 or the program memory 243 corresponding to each weighting level index is used.
The weighting process table 243b is rewritten according to the data corresponding to the weighting level index 705 (a=c) referenced in process 131 from among 01a to 801C. In this example, the weighting level index is the average value (=N/
In the case of 2), the contents of the weighting processing table 243b are made to match the initial data after the power is turned on, and when the weighting level is greater than the average value (=N/2), the key touch feeling is relatively reduced. The structure is such that the key touch feeling is lightened when the key touch is heavy and below the average value (=N/2). Moreover, the setting values of the weighting data groups 801a to 801c are based on the purpose and size of the system.

A greater effect can be obtained by setting the optimum value according to the operation mode.

Further, in this embodiment, the weighting data group is provided in the data table, but the same effect can be obtained even if the weighting data group can be calculated using an appropriate calculation formula.

Process 133 is the last process of the input state detection cycle,
Counters Ci (X) and Cc (X) are cleared to prepare for the next input state detection process.

According to this embodiment, data corresponding to the key human force detection time is stored in the weighting processing table 243b on the program memory 243, the input response time is changed according to the value, and the input key is weighted. By rewriting the weighting processing table 243b as needed by a program according to the input speed and accuracy of the operator, the weighting of input keys is made optimal for the operator at regular intervals. It has the effect of being able to

In addition, according to this embodiment, even when the same system is used by multiple operators, the feel of the key touch automatically changes according to the skill level of the operator. It can provide beginners with a stable key touch feeling.

Furthermore, even if the operator is the same, if the input mode of the system is different (for example, "Kana character input" and "Alphabetic character input"), the operator will be better at that mode.

Even if you are not good at it, you can change the key touch feeling in this embodiment.

Therefore, malfunctions of the system due to erroneous input by the operator can be reduced, which has a significant effect in improving operability for the operator.

〔Effect of the invention〕

According to the present invention, the weighting of input keys can be adjusted to the optimum value at any time during the input operation according to the proficiency level of the operator, that is, the input speed and input accuracy, so that the system malfunctions due to erroneous input. This has the effect of not only improving operability but also providing a key operation feel that is appropriate for the operator's skill level.
