Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a training display device useful for various training such as foreign language pronunciation training.

(Conventional technology) Conventionally, for example, to teach yourself how to pronounce a foreign language,
It is common to practice by imitating images and sounds from language broadcasts on TV, radio, etc., language cassette tapes, language video tapes, etc.

In this type of training, the pronunciation of the model and the pronunciation of the trainee are compared by ear, and on TV or video tape, it is better to compare the movements of the vocal organs such as the lips, tongue, and jaw at the same time. Effective. In this case, generally, a mirror is placed next to the display device, and the movement of the model vocal organ displayed on the display device is compared with the movement of the trainee's pronunciation organ reflected in the mirror.

(Problems to be Solved by the Invention) However, according to the above-mentioned method, the movement of the line of sight fluctuates greatly due to the alternating comparison between the mirror and the display device, which distracts attention and makes it difficult to make accurate comparisons. Furthermore, especially when a cathode ray tube is used as a light-emitting display device, there is a serious problem of eye strain since high-intensity images are viewed from a close distance.

SUMMARY OF THE INVENTION An object of the present invention is to provide a training display device that eliminates these conventional disadvantages.

(Means for Solving the Problems) In order to achieve the above-mentioned object, the first invention of the present application provides a half-mirror via a shutter facing the screen of a light-emitting display device that projects a model image on the entire screen or a part of the screen. The shutter is capable of being opened and closed by a controller, and is characterized in that it blocks light from a portion of the image on the screen other than the model image. It consists of a light-emitting display device that projects divided images, and a half mirror installed opposite the screen.
The dark area of the image is characterized in that it has a size that allows the movement of the trainee's generating organ to be visually recognized.

(Function) As shown in Fig. 1, when viewed from the trainee located on the left side of the half mirror 1, the space on the right side is darker than the left side, the half mirror 1 acts as a mirror, and the second half mirror 1 acts as a mirror.
As shown in the figure, if the space on the right side is brighter than the left side, the trainee can see through the half mirror 1 to the right side.

The first invention of the present application uses the above-mentioned principle to view a model image, for example, an image of a model vocal organ, on a display device through a half mirror, and to view the vocal organ of the trainee through a portion of the half mirror opposite to the shutter. The movements of both are compared within the range of the screen of the display device.

The second invention of the present application allows a model image, for example, an image of a model vocal organ, to be seen through a half mirror in an image on a screen of a display device, and a portion of the half mirror opposite to a dark area in the image on the screen of the display device is mirrored. The trainee's vocal organs are looked at as if they were the same, and the movements of the two are compared within the range of the screen of the display device.

(Example) Embodiments of the present invention will be described below with reference to the drawings.

FIG. 3 shows an exploded perspective view of one embodiment of the invention.

The half mirror 1 faces the screen 3 of the light emitting display device 2, and is attached to the light emitting display device 2 with a light shield (not shown) interposed around it so that light does not enter between the half mirror 1 and the screen 3. The light-emitting display device 2 uses, for example, a cathode ray tube or a plasma display, and is adapted to display a model image, for example, an image of the movement of a model vocal organ, from the entire surface of the screen 3 or, for example, from the right side. A shutter 5 made of, for example, a liquid crystal and whose opening and closing are controlled by a controller 4 is disposed between the light emitting display device 2 and the half mirror 1. This shutter 5 allows the trainee 6 to visually recognize the movement of the vocal organ, for example, of the model displayed on the screen 3.
It has a size that allows the movement of the vocal organs of the person to be visually recognized through the half mirror 1.

Thus, when viewing an image such as a model image on the entire screen of the light emitting display device 2, the controller 4 applies voltage to the shutter 5 made of liquid crystal to open it.

Next, when comparing the movement of the model vocal organ with the movement of the trainee's vocal organ, close the shutter 5 and display the movement of the model vocal organ on the screen corresponding to part A of the half mirror 1. By projecting the image, the trainee can understand the movement of this vocal organ and the B of half mirror 1.
You can compare the movements of your own vocal organs reflected in the parts.

FIG. 4 shows an exploded perspective view of another embodiment of the invention.

This embodiment does not use the shutter 5 and controller 4 as in the embodiment shown in the third figure, but instead imposes restrictions on the image displayed on the screen 3 of the light emitting display device 2. That is, when it is desired to compare the movement of the vocal organ of the model with that of the trainee, the video signal of the vocal organ of the model having a dark area on the left side is reproduced as shown in FIG. 5, for example. Thus, the part of the half mirror 1 facing this dark area acts as a mirror because the light emitted in the dark area is extremely low, so the movement of the vocal organs of the trainee can be seen in this part, and the movement of the vocal organs of the trainee can be seen through the remaining part. You can see the movement of the vocal organs of the model on screen 3.

In the embodiments described above, the light emitting display device 2 is not limited to one that displays images of a language videotape, but may also be a television receiver that displays images of language broadcasts on television.

Incidentally, instead of the shutter of the embodiment shown in the third figure, a shutter whose light shielding can be controlled mechanically may be used.Also, a transparent touch panel switch can be used as the controller 4 shown in the third figure, and this can be used as the half mirror 1. It may be attached to the surface of the half mirror 1 to form an integrated structure.

(Effects of the Invention) As explained above, according to the present invention, a half mirror is installed facing the screen of a light emitting display device, and a part of the half mirror is interposed between the screen and a shutter. Alternatively, by providing a dark area in the image on the screen, it is made to act as a mirror, so that the model image on the screen, for example, the image of the movement of the model vocal organ, and the trainee's vocal organ can be combined within the range of the screen of the light emitting display device. As a result, the movement of the line of sight becomes smaller and the user's attention can be focused on the screen, making the training more effective.
Furthermore, since the half mirror also has the function of an optical filter, it passes a high-brightness image while softening the brightness. Therefore, it also has the effect of reducing eye strain even when staring at it from a close distance with concentrated attention.
