Abstract

PURPOSE:To enable smooth key operations by touching a key top display picture element with a pen for input, afterwards further touching a non-display part and executing the move and display of the key top display picture element. CONSTITUTION:When a key arrangement setting mode is designated, a virtual keyboard KB composed of all key top display picture elements KP is fixedly displayed, the position information of each key top display picture element KP is stored, and the key top display picture element KP is touched by a digitizer pen DP. Next, the desired non-display part to move the key top display picture element KP is touched by the digitizer pen DP. This coordinate position is detected and temporarily stored and afterwards, the key top display picture element KP is displayed at the storage position. The position information of the newly displayed key top display picture element KP is updated and stored in relation to peculiar input information in place of the position information stored last time. Afterwards, it is discriminated whether all the key top display picture elements KP are completely changed or not.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a screen touch type key input device used as a manual input means for a notebook type word processor or the like.

[0002]

2. Description of the Related Art Such a screen touch type key input device has a virtual keyboard KB for displaying a screen on which key tops are arranged as shown in FIG.
When the target keytop display pixel KP on the virtual keyboard KB is directly touched by the digitizer pen DP for coordinate reading, the coordinate position is detected, and position information corresponding to the coordinate position is detected. The input information peculiar to the keytop stored in association with is read and input processing is performed.
This screen touch type key input device has an advantage that handwritten characters can be recognized and input.

[0003]

By the way, each key top display pixel KP in the above-mentioned virtual keyboard KB is
It is fixedly displayed in an arrangement conforming to a general JIS arrangement or in a Japanese syllabary arrangement. This layout just follows the layout of the original type keyboard. Therefore, for an operator who is unfamiliar with the operation of the type keyboard, it cannot be said that the arrangement is optimal, and it takes time to select a target key, and there is a problem that a smooth operation cannot be performed.

Therefore, it is a technical object of the present invention to provide a screen touch type key input device which can be used by arbitrarily changing the arrangement of keys.

[0005]

According to the present invention, as a technical means for achieving the above-mentioned object, a screen touch type key input device is constructed as follows. That is, in the screen touch type key input device in which each key top display pixel on the keyboard display screen is touched with the input pen to detect the position of the key top display pixel and input information unique to the pixel, A mode setting means for the mode, a selection means for position information and input information specific to the key top display pixel touched by the input pen in the key layout setting mode, and then touched by the input pen Moving display means for displaying the selected keytop display pixel by moving the selected keytop display pixel as an image unit from the original position to the detection position where the position of the non-displayed portion is detected, and the keytop display displayed by the moving display means. And a position information updating unit that updates and stores the position information of the pixel.

[0006]

In the case of changing the key layout, first, after setting the key layout setting mode by the mode setting means, when a certain key top display pixel on the keyboard display screen is touched by the input pen, the touched position is changed. Is detected and specific input information stored in association with the key top display pixel is selected by the selection means from that position. Next, when the input pen is touched on the site where the selected key top display pixel is to be moved, the touched position is detected by the moving display means, and the selected key is detected at the detected position. The top display pixel is displayed and the original display of the key top display pixel is erased. After that, the position information updating means updates and stores the position information in which the key top display pixel is newly displayed, instead of the position information stored in association with the input information unique to the key top display pixel. After that, by repeating the same operation for all the key-top display pixels, the key arrangement can be arbitrarily changed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of the present invention will be described in detail below with reference to the drawings. FIG. 1 is a flow chart showing a program of a key layout setting mode for changing a key layout according to an embodiment of the present invention. Next, an operation based on this is shown in a schematic plan view showing a process of changing the key layout in order. This will be described in detail with reference to FIG. First, the key layout setting mode is designated. This mode designation may be performed by individually providing mode setting keys, but may also be performed by touching a plurality of specific existing keys in a predetermined order.

When the key layout setting mode is designated, initialization is performed and the virtual keyboard KB of all the key top display pixels KP is fixedly displayed on the display device as shown in FIG. 2A. The position information of each key top display pixel KP is stored in association with the input information unique to each key top display pixel KP (step S1). Next, as shown in FIG. 7A, a certain keytop display pixel KP is touched with the digitizer pen DP. Now
The case where the key top display pixel KP of "R" is touched is illustrated. Then, the coordinate position touched by the digitizer pen DP is detected, and the key top display pixel KP whose unique input information stored in association with the position information is “R” is selected (step S2), and As shown in FIG. 2B, the display of the selected keytop display pixel KP is reversed (step S3) to display the selection.

Next, as shown in FIG. 2 (b), the non-display portion to which the selected keytop display pixel KP is to be moved is touched with the digitizer pen DP. After detecting the touched coordinate position and temporarily storing the position information (step S4), the selected input information is "R" at the stored position as shown in FIG. 2C.
The key top display pixel KP is displayed, and the original display of the key top display pixel KP disappears. That is, it is moved and displayed (step S5). Then, the position information of the newly displayed key-top display pixel KP is associated with the input information "R" unique to the key-top display pixel KP and updated and stored instead of the position information stored up to the previous time. (Step S6). After that, it is determined whether or not the change of all the keytop display pixels KP is completed (step S7), the process is jumped to step S2, and the routine of steps S2 to S7 is executed to change all the keytop display pixels KP. By repeating until the end, the keyboard layout can be arbitrarily changed, for example, as shown in FIG.

In the above embodiment, the case where the keytop display pixels KP of the initial display are directly moved and displayed at the positions to be changed has been described. However, in the present invention, each keytop display pixel KP is displayed on the virtual keyboard. Since it can be moved and displayed at an arbitrary position on the KB, if the key top display pixel KP is temporarily saved and displayed at a position other than the desired position, the initial display arrangement is destroyed, and then the arrangement is changed again, the operation is performed. Will be easier.

[0011]

As described above, according to the screen touch type key input device of the present invention, after a certain key top display pixel is touched with the input pen in the key arrangement setting mode, the non-display portion to be moved is input. The key top display pixel is moved and displayed by touching it with a writing pen, and the moved position information is automatically updated and stored. Therefore, the user can arbitrarily arrange the key layout to suit his or her preference. It can be changed and smooth key operation can be performed.
