DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to relates to a suitable data waveform display how especially when displaying waveforms of EEG data on the computer screen.

[0002]

2. Description of the Related Art In general, when recording and storing electroencephalogram measurement data, there is a means for printing out the waveform of the electroencephalogram data on a recording paper or recording it on a recording medium such as a floppy disk and converting it into an electronic file. The analysis and analysis of such electroencephalogram data has been conventionally used because it is easy to read on recording paper. On the other hand, when reading the waveform of the electroencephalogram data displayed on the display screen of the computer, the entire length of the waveform usually cannot be accommodated on the display. For this reason, it is difficult to grasp the entire shape of the waveform every time the screen is switched, and it is unacceptable for a user unfamiliar with interpretation because of the cumbersome operation. In this regard, it has been commonly used because it is easy to observe and perform analysis and analysis on the electroencephalogram data waveform on the printed recording paper. That is, in the case of recording paper, if printing is performed on continuous paper with folds, a long waveform can be observed at a glance, and waveforms of distant pages can be easily compared.

[0003]

By the way, even in such a screen display system using a display, the emphasis has been placed on how to make it easier to observe the waveform and take advantage of the electronic file. I hate not using the convenience of using paper.

It is therefore an object of the present invention has combined two parties benefit from the recording paper and the display representation, provides a data waveform display how to enhance the convenience when performing, especially analyzed EEG data screen observed Is to do.

[0005]

A data waveform display method according to the present invention is particularly for reproducing brain wave data and displaying the data on a screen, wherein the data is displayed before and after the waveform of the data of one page currently displayed on the display screen. The subsequent waveforms for a plurality of pages (hereinafter, referred to as front and rear waveforms) are three-dimensionally virtually drawn by the thickness of the pages and displayed at both ends of the display screen, respectively, so that each page is folded. It is possible to visually recognize the data amount of a waveform like a recorded recording paper.

[0006] In this case, for each page of a plurality of pages displayed at both ends of the display screen where the preceding and following waveforms are well-divided, a fold portion of the page is colored with different color layer pixels to obtain a search guide. Alternatively, the waveform of the desired portion of the preceding and succeeding waveforms is opened and displayed on the screen by setting the waveform having the maximum amplitude at the fold portion of the page as a reference for the search.

Further, when comparing two waveforms of different pages, when the pages are flying apart, a thickness portion corresponding to the number of flying pages is arranged at the center of the screen,
The two different waveforms can be simultaneously displayed on the left and right sides of the screen.

[0008] In the above, a desired portion of the front and rear waveforms can be selectively displayed on the screen by clicking on a target page as a target.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, as an embodiment of the data waveform display how according to the present invention, the brain wave data waveform display method
The realized brain wave data waveform display system will be described in detail with reference to the drawings.

FIG. 1 is a block diagram showing a configuration of an electroencephalogram data waveform display system according to the present embodiment. The measured brain waves are written as data using the recording medium 1 such as a floppy disk. It has data reading means 2 for reading brain wave data from the recording medium 1, and the brain wave data passed therefrom is processed in a processing unit 3 for processing as a normal two-dimensional waveform so as to be displayed in a predetermined format.

As shown in FIG. 2, a waveform signal 10 output from the two-dimensional waveform processing unit 3 is displayed at the center of a display screen 4 which is a display output unit, and is a print output unit (not shown). You can print on a printer.

Further, the present system has a virtual waveform drawing processing unit 5 which calculates the data amount (length) passed from the data reading means 2 and determines how many pages are displayed on the display screen 4. Is calculated. As a result, the waveform signal (waveform before and after) output therefrom 1
Numerals 1 and 12 are displayed on both ends 4A and 4B of the display screen 4 in a drawing manner by densely calculating the waveform data amounts obtained by the calculation.

In this case, both ends 4 of the display screen 4
As for the waveform signals 11 and 12 displayed on A and 4B, for each well-divided page of a plurality of pages, a coloring portion of a fold portion of the page may be colored with a different color layer pixel as a guideline for search. it can. Thus, a desired portion of the waveform signals 11 and 12 can be opened and displayed on the screen.

In addition, instead of the coloring process, a waveform having the maximum amplitude is located at a fold portion of each page of a plurality of pages having good breaks, which is used as a reference for retrieval. Thereby, the waveforms of the desired portions of the waveform signals 11 and 12 are opened and displayed on the screen.

By selectively searching for a target waveform signal by a click operation using a mouse with a target page as a target, a target waveform can be efficiently opened and displayed on a screen.

That is, in the case of using recording paper by conventional continuous paper feeding, the waveform of long electroencephalogram data is recorded over several pages or several tens of pages at each fold of the recording paper. The amount of waveform data corresponding to the “thickness” of the recording paper by the plurality of sheets is determined by the both end portions 4A of the display screen 4,
4B, the waveform signals 11 and 12 are displayed.

Therefore, the waveform signal 10 from the two-dimensional waveform processing unit 3 and the waveform signal 1 from the virtual waveform drawing processing unit 5
1, 1 and 12 are displayed on one display screen 4 by being connected to a central portion and both ends thereof, and it can be visually recognized as a three-dimensional stereoscopic waveform display to a user. Note that the waveform signal 10 displayed at the center of the screen is added.
Before and after, the waveform signals 11 and 12 of the data amount of several to several tens of pages are respectively seen to be continuous. As a result, the user can clearly recognize at a glance that the data of the measured electroencephalogram "exists" before and after the screen display portion. This has the same meaning that the data amount can be visually recognized by the number of sheets folded on the recording paper by continuous paper feeding.

Here, the virtual waveform drawing processing section 5 can draw and display the thickness corresponding to the calculated number of pages, and can operate the data reading means 2 by another task in order to draw a heading waveform. Has become. The data reading means 2 which executes an operation by another task sequentially reads out the electroencephalogram data from the recording medium 1 using the idle time of the processing. The read brain wave data is notified to the virtual waveform drawing processing unit 5, and the calculated waveform amount is subjected to waveform processing as the thickness (of the number of screen pages).
Are displayed at both ends 4A and 4B. When the electroencephalogram data read from the recording medium 1 is completed, the data reading means 2 ends the operation.

The switching of the screen page to be sent to the display screen 4 is performed by clicking a thickness portion of a plurality of pages with an instruction device or the like.

As shown in FIG. 3, in the case where two different brain wave data are compared and displayed while the page is flying away from the waveform signals 11 and 12 drawn and displayed at both ends 4A and 4B, The thickness of the distant pages is displayed at the center of the screen, and two left and right brain wave data are compared.

It should be noted that the present invention is not limited to the waveform display of the electroencephalogram reproduction shown in the above-described embodiment, but may be used for the waveform display (recording / reproduction / editing, etc.) of general induction and the like. It is possible.

[0022]

As described above, according to the present invention, the data waveform display how according to the present invention, recording paper and has combined two-party advantage of display representation, convenience in performing, especially analyzed EEG data screen observed Is enhanced. That is, by rendering a long waveform signal virtually on the page thickness referred to on the display screen and displaying it at both ends of the display screen, a three-dimensional display continuous with the waveform signal displayed at the center of the screen can be performed. The user can observe the data amount of the waveform signal on the display as if recognizing the thickness of the page of the recording paper, and it is effective to improve the efficiency of analysis and analysis of various waveform data signals converted into electronic files. It is.
