JPH0667831A - Selective input system - Google Patents

Abstract

PURPOSE:To enable an operator to surely check a message by changing and displaying a message sequentially or at random in each selection and changing an input method in each change. CONSTITUTION:In a selective input system for executing required selecting processing by executing prescribed input operation in accordance with a displayed message instruction, plural kinds of messages 1 to 4 are prepared correspondingly to a certain selecting processing and the contents of a message to be displayed are changed sequentially or at random in each execution of the selecting processing to change the input operation method.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a selective input system for a device having a display section and an input section.

More specifically, the present invention relates to a selection input method for executing a desired selection process by performing a predetermined input operation in accordance with an instruction of a displayed message.

[0003]

2. Description of the Related Art In a device having a display section and an input section,
It is common to make a selection by operating the input unit in accordance with the message displayed on the display unit. A conventional example of this message is shown in FIG.

The example shown in FIG. 4 is an information processing device such as a personal computer, and after the file is deleted (file name'ABC '), it is checked whether the file is really a file to be deleted. It is something to confirm.

Here, if "Y" is input, the file "ABC" is deleted, and if any other input is made, the file is not deleted. This is to avoid deleting another file due to an erroneous operation or the like.

[0006]

However, the operator repeatedly remembers the message for the selection so as to remember the message and to get accustomed to it. rear,
The file name, in this example, has a drawback that "Y" is immediately input without looking at the message in which "ABC" is described.

This does not serve the purpose of the message of avoiding deleting another file due to an erroneous operation or the like.

Therefore, an object of the present invention is to provide a selection input method in which an input operation for selection is performed after always confirming a displayed message.

[0009]

In order to achieve the above object, the present invention provides a selection input method for executing a desired selection process by performing a predetermined input operation in accordance with an instruction of a displayed message. A plurality of types of messages are prepared for one selection process, and the contents of the message to be displayed are changed sequentially or randomly each time the selection process is executed, thereby changing the input operation method.

[0010]

According to the present invention, a plurality of types of messages are prepared for one selection process, and the messages are sequentially or randomly changed and displayed for each selection, and the input operation method is changed each time. As a result, the operator always checks the displayed message in order to know how to perform the input operation.

EXAMPLES Examples of the present invention will be described in detail below.

Embodiment 1 FIG. 1 is a drawing explaining a display mode in an embodiment of the present invention. In the figure, 1 to 4 are examples of messages after a file deletion instruction similar to the conventional example shown in FIG. Here, 'ABC' indicates the file name for which deletion has been instructed.

After the first file deletion instruction, message 1 is displayed, and if'Y 'is input, the file is deleted, and for other inputs, the file deletion is stopped.

After the next file deletion instruction, message 2 is displayed, and when "G" is input this time, the file is deleted.

Further, after the next file deletion instruction, message 3 is displayed, and when'D 'is input,
Make sure to delete the file.

After the next file deletion instruction, message 4 is displayed, and when "E" is input, the file is deleted.

After the next file deletion instruction, the process returns to the message 1.

In this way, if the message is changed every time and the input method is changed, the operator will see the message to confirm the input method, and it is possible to avoid accidentally deleting another file. .

FIG. 2 shows a flow chart when a file deletion is instructed. Here, in step S1, "message
"pointer" is assumed to be set to zero in the initialization routine. Further, “modulo” in step S6 represents a modulo remainder.

Second Embodiment In the first embodiment described above, the contents of the message are sequentially changed. However, it is also possible to change the display contents at random so that the operator's attention can be called.

That is, in the second embodiment, messages 1 to 4 are randomly selected and displayed for each file deletion instruction. For that purpose, an integer of 0 to 3 may be randomly generated in step S21 of the flowchart shown in FIG.

As described above, if the displayed message is randomly changed every time and the input method is changed, the operator will see the message to confirm the input method, and it is possible to delete another file by mistake. Avoided.

In step S21 shown in FIG.
“Random” represents a function that randomly generates an integer of 0 to 3 as described above.

[0024]

As described above, according to the present invention,
By changing and displaying the message sequentially or randomly for each selection and changing the input method each time, the operator always confirms the message.
