It has functions for controlling an input time control section 3, an input data judgment section 6, an input key size determination section 4, and an input screen display section 5.

FIG. 2 is an elliptic diagram showing a configuration example of a user adaptive input key size setting device according to the second invention. In the figure, a touch panel 12 overlaid on a flat display 13 is an information input device, which is connected to the computer main body 1l.

As for the overall process, in order to determine the key size suitable for the user, first, the appropriate size key and instructions for the key to be pressed are displayed on the flat screen display [3], and the user gives the instructions. When a key is pressed, the time until the key is pressed and a comparison between pressed key information and instruction information are detected as information, and the size of the key is determined to suit the user.

FIG. 3 is a diagram showing the structure of the user-adaptive input key size setting device according to the third invention. In the figure, a video camera 22 is set above the flat display 23,
Both are connected to the computer main body 21. As for the overall process, in order to find a key of a size suitable for the user, first, a key of an appropriate size and an instruction of the key to be pressed are displayed on the flat screen display 23, and the user follows the instructions. When a key is pressed, the video camera 22 located at the top records the movement, detects the time until the key is pressed and a comparison between pressed key information and instruction information as information, and adjusts the size of the key to suit the user. Determine.

In determining the key suitable for the user of the second and third inventions,
There are two possible methods: directly touching the switch using a touch panel or the like, and determining the size of the key without touching the switch using a video camera or the like.

FIG. 4 is a flowchart for determining the key size suitable for the user in the embodiment of the first invention. This corresponds to the flow in the input key size determining section 4 in FIG. Regarding reading information, input time data from input instruction to actual input is collected in step 3.
In step 1, judgment data indicating whether the input data is correct or incorrect with the instruction is read in step 32.

Based on these data, first, in step 33, the input time data and the input time guide value are compared. The input time guide value represents the maximum allowable time it takes to input.If you need detailed operations that take longer than that, increase the size of the keys. It is necessary to think about how to input data more quickly.

Further, regarding the judgment data, a judgment is made in step 34 as to whether the answer is correct or incorrect.

If the input time data is larger than the input time guide value or if the judgment data is an incorrect answer, the size of the key is increased in step 35 to make it easier to input.
The data obtained from this series of operations is then written as input key size data into the input key size data storage section 7 of FIG. 1 in step 36.

FIG. 5 is a flowchart for setting the screen presented to the user according to the first invention. This corresponds to the flow in the input screen display section 5 of FIG. Regarding reading of information, in step 41, data of the key size used for display obtained by the input key size determination unit 4 of FIG. 1 and the process of FIG. 3 is read.

In order to display ρ on the actual screen, first, in step 42, the content of the key to be used for the next input instruction from the user is determined. Then, in step 43, each data for display in which keys are arranged according to the input key size data is generated. Then, in step 44, actual drawing is performed.

Finally, in step 45, the display data obtained from this series of operations is written into the display data storage section 8 of FIG.

FIG. 6 is an explanatory diagram showing an example of the input keys of an actual user-adaptive input key size setting device. FIG. 6(a) shows an input screen when the size of the keys is relatively small. In this state, input is performed by selecting and pressing the key specified at the top of the screen from the set of keys at the bottom. FIG. 6(b) shows an input screen when the size of the key is large.

If the key size is small as shown in Figure 6(a), it may take a long time to input or input errors may occur, so if it is determined that it is difficult to input, the key size may be gradually increased. Revitalize the screen. FIG. 6(c) shows a similar input screen, but the display is arranged freely so as to be relevant to the work content. By doing so, it becomes possible to determine the key size that is more suited to the work content and physical characteristics.
