Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an operation for displaying and sensing spatial / temporal tactile information such as character codes or iconographic information on a user's finger and writing and inputting character codes or other information (hereinafter, input operation). The present invention relates to a tactile information device and an operation support device for controlling communication means for a person with a disability or the like, and in particular, to enable the finger of a wearer to input character code information at a free position and obtain tactile information. The present invention relates to a tactile information device and an operation support device for operating a remote operation target in a model manner.

[0002]

2. Description of the Related Art Needless to say, tactile sensation of a finger is effective as a communication means used by a visually impaired person or a hearing impaired person in place of sight or hearing. 2. Description of the Related Art Conventionally, six-point code braille by the tactile sensation of a finger is known. Furthermore, based on this, as a communication means devised so that two people can immediately communicate, a finger character encoding system that conveys which one of three fingers, one finger and six fingers, both fingers are touched. It has been devised. When a visually impaired person or the like receives iconographic information, the shape of the icon can be recognized by rubbing the edges of the icon with his or her fingers.

Conventional devices that display information (also referred to as presentation) by giving a tactile stimulus to a visually impaired person or the like include a tactile indicator for giving six points of tactile stimulus to a finger using the above-mentioned finger character encoding system. In addition, there is a dynamic indicator that applies a force to a finger as if there is an object fixed there according to the spatial position of the finger, and displays the force using an artificial inertial force. Each of the displays was fixed to a desk or the like. In addition, a keyboard device used as an input device is also fixed and installed.

[0004] Even when the display and the input device are usually provided separately from each other to some extent or provided close to each other, since both devices are independent from each other, their functions are operated separately. Will be.

[0005] Even for sighted persons, there is a case where the operation with fingers is effective in daily communication.

Alternatively, in a case where a sighted person operates a certain operation target (remote operation of a robot device or a monitoring target in the case of monitoring) while looking at the display of the model image, for example, It has been clarified that it is important to give a finger a sense of contact with an operation object in order to perform operations such as grasping and moving with more realism.

[0007]

As described above, since all of the conventional devices for displaying tactile information are fixedly installed on a desk or the like, the user of the device restricts the movement of fingers to a narrow range. However, there has been a problem that there is a great limitation in the form of use. In addition, the keyboard of the input device and the like also restrict the movement of the user by restricting the position of the finger to a fixed position, and there is a problem that it is very difficult to use the keyboard if visual information cannot be obtained.

Further, since the display unit and the input unit are provided separately from each other, it is not possible to perform input driving and display reading in parallel as in the case where there is visual information, and the user himself inputs the data. There has been a problem that it is not possible to read information immediately to confirm input contents.

Further, when displaying an icon image using the above-described conventional tactile display device, if tactile information is obtained from only one fingertip without performing inertial force display, when the fingertip is in contact with the icon image, Information can be obtained, but information cannot be obtained if the fingertip deviates from the icon image. Therefore, the search must be performed until the icon is again touched, and even if the icon is touched again, the connection with the contact point until the touch is not released cannot be recognized, and the information of the contour is lost. It has been found that in order to recognize the shape of the iconic image, it is necessary to rub the outline thereof. As a result, there is a problem that the conventional device cannot recognize the accurate shape of the iconic image or the uneven object.

Therefore, the present invention has been made to solve the above-mentioned problems of the prior art, and a first object of the present invention is to allow a user to drive and read at an arbitrary position,
Another object of the present invention is to provide a tactile information device capable of immediately reading and confirming its own input.

[0022]

Embodiments of the present invention will be specifically described below with reference to the drawings.

(First Embodiment of Tactile Information Device) FIG. 1 is a block diagram showing a system configuration of a first embodiment of a tactile information device according to the present invention, and FIG. 2 is an explanatory view of a main part of the device. .

In FIG. 1, reference numeral 1 denotes a tactile indicator, which generates a stimulus to a tactile receptor and displays information (also referred to as presentation). Reference numeral 2 denotes a motion detector for detecting the movement of a finger. Here, a piezoelectric vibrator was used as the tactile indicator 1, and a strain sensor was used as the motion detector 2.

The tactile indicator 1 and the motion detector 2 are shown in FIG.
Are arranged on the finger cot 20 in pairs as shown in FIG. The finger cot 20 has a cylindrical shape through which one finger can be inserted,
In the mounted state, the motion detector 2 is positioned on the dorsal side of the finger across the first joint 21 and the second joint 22, and the tactile indicator 1 is positioned on the finger pad side ahead of the first joint 21. I have. The motion detector 2 detects and outputs a distortion signal according to bending or stretching of each joint of the finger. The tactile indicator 1 is driven and vibrates as described later, and can apply a predetermined vibration stimulus to the finger pad. A pair of the tactile indicator 1 and the motion detector 2 indicated by a broken line is provided for six fingers including one finger and three fingers.

The tactile indicator 1 and the motion detector 2 are worn on a back of a finger or a wrist like a wristwatch by a belt-like member (not shown), for example, as shown in FIG.
And are electrically connected by signal cables 23 and 24.
The control unit 3 includes, for example, an infrared communication unit (not shown), and sends out a detection signal of the motion detector 2 to an IR port of the work station main body 6 via an infrared wireless path. The work station body 6 transmits a character code signal converted from a voice or a character code signal from another character information generator to the control unit 3 in an infrared manner in a character-by-character time series.

The encoding method of the character code signal transmitted from the work station body 6 is extended from the braille format of six points, and the character is identified based on which one of the three fingers of one hand and the fingers of six fingers is touched. The finger character encoding method as described above is used. The control unit 3 generates a drive signal corresponding to the character code signal from the work station main body 6, and thereby vibrates the tactile indicator 1 of each finger. By determining this stimulus, the wearer can read the transmitted character string. At this time, information other than the three fingers of each finger using the character code can be used for another identification code.

Alternatively, by stimulating only one hand by converting the signal given to the six fingers of both hands by the above-described method into two time-series signals and stimulating only one hand, it is also possible to discriminate with one finger. Further, in addition to the five fingers of one hand, by using a code having one wrist or instep of the one hand, a total of six parts are stimulated so that one finger can determine six pieces of code information. You can also.

On the other hand, when the wearer strikes and sends out character information, he or she moves his or her finger in the same manner as a striking operation using a keyboard by bending and stretching each finger in accordance with the same finger character code to be read. The motion detector 2 detects the motion of each finger, and this detection signal is input to the work station body 6 via the control unit 3, and the character information by the driving operation is decoded here.

As described above, according to the present embodiment, the tactile indicator 1 and the motion detector 2 can be mounted on a finger in pairs, and transmission and reception with the work station body 6 can be performed wirelessly. Information can be transmitted and received in a state where the position and position are not restricted by these devices. That is, the wearer can strike and read at an arbitrary position. In addition, it is possible to eliminate the inconvenience of driving and reading due to the restriction of the movement of the finger when installed on a desk or the like.

Further, in the above configuration, the character code input and inputted can be simultaneously turned back and displayed on the vibrator 1 by either the control section 3 or the work station main body 6. Here, signals other than the finger of the finger character code can be used as various operation codes. In the case of the above-described embodiment using a six-point code with one finger, a strain sensor can be attached to a finger or the like to send a code with one bending motion of the finger or the like.

By doing so, there is an effect that the information input by the wearer himself can be immediately read and the input content can be confirmed.

It is to be noted that a small motor type vibrator may be used as the tactile indicator 1 instead of the piezoelectric vibrator, and a magnetic sensor may be used as the motion detector 2 instead of the strain sensor in a non-magnetic field environment. It is also possible.

The pressure sensor 34 omitted in FIG. 4 is provided so as to be able to detect the pressure of the pneumatic pliers 33, thereby detecting the inflation and contraction of the pneumatic pliers 33 in accordance with the bending and stretching of each joint of the finger and the like. A detection signal is output through 43.

The pump 32 omitted in FIG. 4 is of a small type, and can be worn like a wristwatch, for example, by a belt-like (not shown) around the back of the finger or the wrist. The air sent from the pump 32 is sent to the pneumatic bag 31 through a thin air tube 44. Therefore, the pneumatic pouch 31 is driven by the above-mentioned air sent from the pump 32 driven by the drive signal from the control section 35.
Can be expanded and contracted, and a predetermined pressure stimulus that changes according to the character code can be applied to the finger pad.

The pair of the pneumatic slats 31 and the pneumatic slats 33 indicated by the broken lines is provided for six fingers including one finger and three fingers.

The display element 60 includes vibrators 61 to 66 two-dimensionally arranged like the display element 50.

When one finger on which the display element 60 is mounted is moved substantially along the broken line, and the outline of the graphic is searched in the order of, for example, 60 → 60a → 60b, each of the vibrators 61 to 66 becomes an object as follows. The vibration amplitude changes according to the amount of unevenness of the image.

In the display element 60, the vibrators 61, 62, 64,
65 is not driven, and vibrators 63 and 6 of small black circles are not driven.
6 is driven with a small amplitude. Next, in the display element 60a, the vibrators 61, 64, 65, and 66 are not driven, and the normal black circle vibrators 62 and 63 are driven with normal amplitude. In the display element 60b, the vibrators 64, 65, and 66 are not driven, the small black circle vibrator 61 is driven with a small amplitude, and the normal black circle vibrators 62 and 63 are driven with a normal amplitude. .

The optical mark piece 80 does not restrict the position or movement of the wearer, but has different shapes and colors for each finger. For example, a label-like mark piece with one side coated with an adhesive for sticking to the finger is applied, and the other side is colored with high reflectivity. (It is better to be able to distinguish them.) The camera 8 sets various parameters such as an installation position and an angle of view so that the entire movement range of the finger of the wearer can be imaged. This does not apply to a camera having a tracking function and capable of coping with the movement of a finger to be imaged.

The control section 83 can omit the function of processing the detection signal, and this function is changed for the image picked up by the camera 8. Therefore, the control unit 83 can be simplified and downsized, and the physical burden on the wearer can be reduced. Also, if the function of driving the display 1 is omitted, the control unit 83
The body itself can be deleted, and the physical burden on the wearer can be further reduced.

With the above arrangement, the position / movement of the finger is detected from the characteristics of the image of each of the captured mark pieces as described later. Alternatively, it is conceivable to take an image of the finger itself without attaching the optical mark piece in particular, and measure the position / movement using the characteristics of the finger itself from the characteristics of the video.

Next, several methods for detecting the position / motion of a finger will be described.

Since the position of the third joint of each finger is substantially the same except for the bending and stretching motion of the finger except for the thumb, for example, a point-shaped optical mark piece is attached to these third joints to obtain the reference position information. Source. The relationship between other fingers and the reference position is initially set. Each finger is photographed by one camera 8 and collation is performed to detect the position and movement of each finger.

Two cameras are provided at appropriate positions. The optical mark piece attached to the back of the first joint of each finger is
Take an image with one camera. The position is measured from the captured image according to the principle of triangulation.

A finger image is detected from an image picked up by one camera, and its position is measured by comparing its shape with a preset finger motion model. Hand image detection
Focus on the difference between skin color and background color.

The positions of all the images captured by the plurality of cameras are measured in accordance with the principle of triangulation, and the finger image is separated based on the difference between the distance between the background image and the finger image in each captured image, and finally the position is measured.

(One Embodiment of Operation Supporting Apparatus) Each of the above embodiments implements a tactile information device for a disabled person or the like, but in this embodiment, a sighted person operates an operation target such as a robot. A device for realizing easy operation with real feeling when operating is realized.

FIG. 9 is a block diagram showing a system configuration in an embodiment of the operation support apparatus according to the present invention.
1 shows a configuration in which an operation target robot 90 is added to the configuration of FIG. 1. The display 1 can be omitted depending on the necessity, but the image monitor 7 is an essential element for displaying a CG image or the like.

In the station main body 6, for example, a code by an operation of grasping an object by a thumb and an index finger is made to correspond in advance to an operation of grasping and moving the object, and an operation target image displayed on the image monitor 7 when the operation is detected. Can be newly set according to the operation to control the icon image.

Then, as shown in FIG.
The image 120 of the finger and the finger is modeled by computer graphics and displayed on the image monitor 7, and a control signal corresponding to the above operation is sent to the robot 90 for control. Further, the display device 1 is driven so as to stimulate the tactile sensation in accordance with the above-mentioned operation, and the physical property of the operation target is given to the finger, so that the image monitor 7 is displayed.
The spatial position operation of the icon image can be performed by giving a sense of realism that the wearer is actually operating the upper CG image.

In order to reliably detect the movement of the finger, a planar electronic switch is provided at the tip of the finger on the finger band.
Thereby, the operation code may be generated by the contact of the finger.

The function of the pointing device in the multimedia information display screen can also be realized by using a signal from the detector 2 for detecting a finger movement for cursor movement.
