Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of an artificial eye for enhancing an emotional expression function and a robot using the artificial eye, and to express an emotion by substituting an eye function with an electronic display element. Features include industrial robots, pet robots, nursing and auxiliary robots, guide boards,
It can be applied to a large number of devices in which emotional expression plays an important role, such as acceptance work, portraits, and mannequins.

[0002]

2. Description of the Related Art The eyes of living things are extremely important for expressing emotions, and emotions such as emotions are largely due to facial expressions centered on the eyes. Therefore, it is important for robots to have similar eyes to living things as much as possible in order to give them familiarity, familiarity, and cuteness.

The eyes of living beings usually have a shape and size peculiar to living things, but they are generally close to a round shape or an elliptical shape. The visible parts are the cornea covered with the eyelids, the iris, and the pupil. There is a lens, retina, macula, etc. It is usually convex outward, and the brightness is adjusted by opening and closing the pupil, the line of sight is determined by the rotation of the crystalline lens, the eyelids are opened and closed, and the pupil size, crystalline lens position, eyebrow shape, tears, etc. Together they are in charge of emotional expression.

In the past, various robots have been developed and put into practical use as substitutes for human superior functions and as high-tech toys.

Japanese Unexamined Patent Publication No. 2000-070557 describes "a doll whose eye part is a display device such as a liquid crystal and the display of this display device is changed to change the facial expression of the doll".

Further, Japanese Patent Laid-Open No. 2001-215940 proposes an intelligent robot capable of expressing emotions of emotions by projecting an image in which a whole part corresponding to a face is displayed on a display element such as liquid crystal.

[0007]

However, it must be said that the robots so far have been mainly primitive in motions and gestures, and the eyes that are important for emotional expression are extremely primitive and expressionless. I can communicate more in the future,
A cute and friendly robot is required, and the eyes are extremely important for communication. Emotions and emotions largely depend on facial expressions (especially eyes), and robots that can express emotions will be indispensable in the future from the viewpoint of coexistence between humans and robots, instead of expressionless robots.

However, in the conventional robot or high-tech toy, the function corresponding to the eyes is merely using the blinking of the LED and the display with a limited pattern, and it is extremely effective in terms of facial expression, friendliness, and communication. It was insufficient.

In Japanese Patent Laid-Open No. 2000-070557, the structure of the artificial eyes and the specific means are not clarified merely by displaying the emotional pattern with the conventional liquid crystal or LED, and no consideration is given to curved surfaces or atypical shapes. It could not be a high emotional expression.

Further, in Japanese Unexamined Patent Application Publication No. 2001-215940, the size of the robot becomes large and it cannot be applied to stuffed animals, pet toys, and cordless robots. In addition, when the whole face is used, the shape of the screen becomes complicated, and it is difficult to always match the projected image with the shape of the screen when the facial expression is changed, which is rather unnatural.

Therefore, the present invention is an artificial eye characterized in that a transparent convex body is provided on an electronic display element so as to be as similar as possible to the eyes of living beings, and the pattern displayed on this artificial eye makes it possible to realize reality. The objective is to provide an artificial eye that achieves high emotional expression and a robot that uses the artificial eye.

[0012]

In an artificial eye and a robot using the same according to the present invention, an electronic display element provided with a transparent convex body is used, and a pattern similar to the eye is obtained according to an electric signal corresponding to an emotion. The display is configured to express emotions.

According to the present invention, an electronic display element provided with a transparent convex body so as to be as similar as possible to the eyes of a living being is used, and an artificial eye which achieves highly realistic emotional expression by the pattern displayed on the electronic display element and the artificial eye. The used robot is obtained.

Further, the artificial eye configured as described above is far more complicated than the conventional simple pattern display using a flat-plate liquid crystal or LED, mechanical eyelid opening / closing, and rotation of the crystalline lens. You can display delicate patterns,
It enables richer emotional expression. This will enable many future electronic devices such as personal computers, PDAs, mobile phones,
Electronic pets, watches, audio-visual equipment, electronic game consoles, character goods, etc. can now have emotions and playfulness, and become more familiar than ever.
It provides relaxation, fun, personality, and usability.

FIG. 1 shows an embodiment of the present invention.
4 to FIG.

(Embodiment 1) FIG. 1 is a front view of an electronic display device for artificial eyes according to a first embodiment of the present invention, and FIG.
FIG. 3 is a side view of the electronic display element.

As shown in FIGS. 1 and 2, the artificial eye according to the first embodiment of the present invention has a transparent convex body 2 made of glass or plastic having a surface provided with an antireflection film. Liquid crystal, electrophoretic display panel, variable mirror display panel, etc. can change the reflection pattern, or EL (Select)
It is characterized in that it is configured by providing an electronic display element 1 capable of changing a light-emitting pattern such as a roluminance), and that its display pattern is changed by an electric signal corresponding to an emotion. Here, the transparent convex body 2 has a shape similar to the structure of an eye of a living being, and has a feature that not only the appearance but also the movement of the eyeball, the opening and closing, etc. can be more realistically expressed by the lens effect.

Naturally, the artificial eyes can express delicate emotions by increasing the types of patterns that can be displayed by the display patterns. That is, in general, an electronic two-dimensional display element has X
The Y-matrix electrode configuration is adopted, and the larger the number of both electrodes is, the larger the number of gradations is, and the more complicated and delicate patterns can be displayed so that multicolor display can be performed. If the electrodes are composed of a plurality of segments, the structure of the display element and the driving circuit are simple, but the types of patterns that can be displayed are restricted. Which of the electrode configurations should be used may be selected according to the purpose.

Human emotional expression is not simply determined by pupil size and lens position, but eyebrow shape, mouth shape, shape and wrinkle formation due to expansion and contraction of facial muscles, crystalline lens, capillary tube,
The color of the eyes and skin is comprehensively expressed. Therefore, in order to construct a more realistic artificial eye,
It is desirable that it is full-colored and the unevenness of the display surface has a shape peculiar to the creature. If all of this can be reproduced, it will be the most realistic emotional expression, but it is difficult to achieve all of these with the current technology. However, the size of the pupil, the position of the crystalline lens, the degree of eyelid opening, the shape of the eyebrows, etc. can be simulated to some extent by the pattern displayed on the display element.

A film liquid crystal panel using a polymer film substrate has already been put to practical use as a mobile phone or a watch. The film liquid crystal panel has a feature that, unlike a rectangular and flat glass liquid crystal panel, it is easy to display irregular shapes or curved surfaces.

As shown in FIG. 1, on the electronic display element 1 which is an elliptical XY matrix type black-and-white film STN liquid crystal panel, a transparent convex body 2 made of plastic whose surface is anti-reflection treated with an adhesive. The basic shape of the artificial eye can be formed by pasting.

FIG. 3 is an explanatory view showing the one-eye portion on the right side of the electronic display element.

The electrodes of the STN liquid crystal panel have an XY matrix structure as shown in FIG. 3, and are composed of, for example, 64 vertical electrodes (row electrodes 8) and 128 horizontal electrodes (column electrodes 9). Is used, and gradation display of about 8 gradations is possible by applying a drive signal called a normal voltage averaging method. Two eyes are usually present at a certain distance, but the scanning electrodes can be shared by the two eyes, and only the signal electrodes need to be separated for both eyes. Note that reference numeral 7 in FIG. 3 represents a seal.

If the resolution is about 64 × 128 pixels, it is easy to drive both eyes with a one-chip LSI, and an FPC (Flexible Printed Ci)
rcuit) and TAB (Tape Automated)
Bonding) flexible circuit board 6, liquid crystal drive LSI 5, terminals of liquid crystal panel column electrodes 9 and FPC
For example, HSC (Heat Seal Conn)
connector) (not shown) or the like.

Although it is simplified in FIG. 1, it is possible to form the row and column electrodes so as to be drawn out on the same surface by using a well-known resin ball for vertical conduction.

FIG. 4 shows a side view of a display element in which electronic display elements for both eyes are integrally joined. The feature of the film liquid crystal panel is that it is easy to form an arbitrary shape,
As shown in FIG. 4, it is easy to form the display element 10 in which the electronic display elements for both eyes are integrated. In this case, the scanning electrodes can be made common, and only the liquid crystal cell of the signal electrode portion can be separately provided, and it is easy to configure both eyes with one liquid crystal cell. A curved surface is preferable to a flat surface for a highly realistic artificial eye. To make a curved type liquid crystal panel, in addition to manufacturing the panel with a flat surface and then sticking it to a convex structure to form a convex shape, in advance when manufacturing a liquid crystal cell, for example, by bonding the upper and lower sides of the substrate and curing it, it is curved. Alternatively, it is possible to use a method in which it is placed on a flat surface, or is formed on a flat surface and heat-treated in a curved state using a mold or the like.

In the above example, the black-and-white STN reflective liquid crystal panel has been described as an example. However, a known transflective or transmissive panel structure is used.
If a film-like back light source such as EL is provided or the structure itself is configured as a back light source, the artificial eye can be seen even in a dark place. Color S that has already been put to practical use
With the TN configuration, color display is possible, and it is possible to configure artificial eyes with higher reality. ST
Not only N mode but TN, guest-host liquid crystal, cholesteric liquid crystal, ferroelectric liquid crystal, PD (Polymer Di)
Modes such as sperse (polymer dispersion) can also be used as a film liquid crystal panel.

The structure of the XY matrix electrodes is selected according to the purpose such as the usual orthogonal type, the elliptical type as shown in FIG. 3, the number of electrodes, the electrode pitch, etc., such as the required resolution, size and cost.

(Embodiment 2) Although the liquid crystal panel has been described in the first embodiment, the drawback of the liquid crystal panel using the polarizing plate is that the reflectance is 50% or less and the display is dark. Similarly, there is an electrophoretic display technology as a well-known electronic display method capable of displaying curved surfaces and having excellent reflectance (see 2001 for details).
(See Chapter 8 of "Handbook of Electronic Information Display", published by Baifukan in July 2012). In order to construct the curved-type electronic display device of the present invention, a dispersion system for electrophoretic display is encapsulated between a film substrate having an ITO transparent electrode and a FPC substrate having segment electrodes designed to express a facial expression. Or, it is sandwiched in the form of individual cells and a voltage of a predetermined polarity is applied between the segment electrode and the ITO electrode to provide a reflective expression display element excellent in brightness and viewing angle.

(Embodiment 3) The eyes of a living being are of a reflective type. However, if the light-emitting display element that emits light by itself is used in the artificial eye of the present invention, the facial expression can be read even in a dark place, and a toy or a mannequin or the like can have an artificial eye with an impact.

For this purpose, a dispersion type EL in which phosphor particles are dispersed in a polymer or an organic EL in which a thin film light emitting layer is sandwiched between electrodes can be used. Flexible organic ELs of each color using a polymer substrate have already been developed. It is possible to form the artificial-eye electronic display device of the present invention by utilizing a substrate such as a glass substrate, a polymer film, a metal thin film, or an FPC.

As described above, in the first to third embodiments,
So-called simple matrix or static drive display elements using liquid crystal, electrophoresis, variable mirror display elements, EL, etc. as display elements have been described. However, an active matrix realizes a display of higher quality such as resolution, contrast, response speed, viewing angle, and number of colors.

As a method of forming an electronic display element by a film type active matrix, there are mainly the following means. (1) A two-terminal or three-terminal inorganic active matrix is formed on the film by a low temperature process that the substrate film can withstand. (2) The active matrix formed on a rigid substrate such as glass is transferred onto a film substrate. (3) An organic TFT or the like that can be formed at low temperature is directly formed on the film. (4) An active matrix is formed by a high temperature process on a heat-resistant substrate such as a stainless steel film coated with an insulating film that can be easily curved.

If a display element such as liquid crystal, electrophoresis, variable mirror display element or EL as shown in FIG. 1 is constructed by using the flexible active matrix substrate, an electronic device with a higher impact and capable of expressing abundant emotions can be obtained. It becomes a display element.

Particularly suitable as a small-sized flat panel type electronic display device is a so-called silicon-based display device which directly utilizes a crystalline Si substrate, that is, LCOS (Liquid Cr).
It is called as the "ystal on Silicon", and is characterized in that it can utilize Si semiconductor technology and equipment already highly developed as an active matrix.
Micro processing is possible, it is easy to make a high density, high resolution display element, the drive circuit can be integrally formed, so the size of the display element including the drive circuit can be made minute, and an ultra-compact, high-definition one is realized at low cost. You can, and so on. For example, a display capacity (8
52 × 3 × 600 dots) 15.6 mm diagonal (pixel pitch 15 μ) full-color display, Zight 4.8 mm diagonal 320 × 240 dots (pitch 12)
μ) liquid crystal displays are already in practical use. If these high-definition microdisplays are used, it is possible at present to make an artificial eye using the electronic display element of the present invention in a size corresponding to a human eyeball. It is also easy to use an integrated type in which both eyes are built in close proximity to each other, and an optical system may be used to project the image on the screen while separating the two eyes. When a Si substrate itself is used as a silicon-based display element, since it is light opaque, only a reflective structure is possible.
A type in which an active matrix formed on a substrate is transferred to a transparent substrate such as glass can be used as a transmissive flat panel type electronic display element. A transmissive liquid crystal display with a diagonal size of 6 mm and a number of pixels of 320 × 240 manufactured by Kopin Co., Ltd. in the US can also be used, and full color can be realized by a field sequential method. High temperature p-Si formed on quartz or glass substrate similar to silicon-based active matrix
And low-temperature p-Si is also a widespread a-Si TFT that can form a small high-definition display with a built-in drive circuit.
Needless to say, can also be used as a transmissive and reflective electronic display device. Silicon-based display device, p-Si
Alternatively, as the display medium for an a-Si-based active matrix display element, many ones such as liquid crystal, electrophoretic dispersion system, variable mirror display element, organic and inorganic EL can be used.

By providing the artificial eyes according to the first to third embodiments to various robots for guidance and other purposes, this robot can express a variety of emotions, so that there are variations in operation. Can be increased.

The artificial eye of the present invention has been described above focusing on the electronic display element, but another important function of the artificial eye is the correspondence of the facial expression to the external stimulus. The ability of the artificial eye to properly respond to external stimuli such as light, sound, and temperature is important as a friend and more familiar being to humans.

That is, since the artificial eye of the present invention and the robot using the artificial eye are highly realistic, if one or more sensors for light, sound, and temperature are provided in or near the artificial eye itself, a person can approach. You can judge the direction, distance and strength by speaking and direct your gaze to that direction, be surprised, act mesmerizing and respond appropriately to the external stimulus, and you will be even more familiar Will increase. If the eyes of an actual living being are captured by one or one CCD camera for both eyes and this signal is sent to the artificial eye of the present invention and displayed, emotions, blinks, winks, and other movements that change moment by moment. The target expression is displayed, and it is possible to have a dramatic effect with a mannequin, an advertisement man, a receptionist, etc.

The artificial eyes in the present invention may mean only eyeballs, or may be a general term for the vicinity of the eyes that affect emotional expressions including eyelids, eyelashes, eyebrows, etc., and robots are similar to the eyes of living things. It is a general term for things that express expressions.

In general, the expression "artificial eye" often refers to an artificial sensory device that stimulates the cranial nerve system by an electric signal through a stimulation electrode embedded in the body to restore the vision of a blind person. That is, a TV camera captures the surrounding scene, image processing such as feature extraction is performed to create image data, and MEMS (Micro-Ele) embedded in the body is used.
Critical Mechanical System
m: Wired or wirelessly transmits image data and power for driving the MEMS to a micromachine equipped with an electronic circuit. M
The EMS produces an electric pulse signal similar to a nerve signal based on the transmitted data and transmits the signal to the cranial nervous system through the stimulation electrode. It is thought that lost vision can be restored by artificially sending a visual signal into the brain in this way.

On the other hand, an artificial retina LSI has already been developed and put into practical use, and is an LSI having an image processing function simulating a human retina, which has a higher speed and higher image processing function than a conventional CCD, It works effectively as a signal source sent to the MEMS.

The artificial eye of the present invention described so far only displays a display imitating the true eye, and does not have the visual sense of the true eye. However, the actual vision is the above MEM
If S controls and changes the display of the artificial eye of the present invention in response to the action (movement of the line of sight, opening / closing of the pupil, etc.) according to the visual information sent to the brain, conventional facial expressions are not involved. It is possible to express emotions much closer to the true eyes than the artificial eyes.
