Description

【0001】
【発明が属する技術分野】
本発明は、視覚障害者を対象とした周辺情報の認識装置の構造及び情報伝達方法に関している。
【0002】
【従来の技術】
従来の認識装置は実際に手で持って使う構造、メガネ型の構造、ペンダント型の構造、白杖型の構造で作られている。
【0003】
メガネ型の構造は普通のメガネより重くなり、使用者に負担をかける。
【0004】
また、ペンダント型の構造の場合、認識したい個所に体を向ける必要があり細かい場所の認識は不可能である。又、手で持って使う場合には手がふさがり不自由になる。
【0005】
また、白杖型の構造は、白杖を動かすたびに測定場所も白杖と一緒に動いてしまって測定個所が定まらない。
【0006】
また、周辺情報を伝達する手段は音と振動があり、音では音程の変化、振動では回転数の変化で伝達していた。
【0007】
音程の変化は人ごみなどの雑音の中では聞き取り難い場合が多く、振動回転数の変化や音程による距離の情報伝達法は、習得に時間が掛かる。
【0008】
【発明が解決しようとする課題】
解決しようとする課題は、周辺情報の認識装置を手で持つことなく安定に装着できる事。
【0009】
上記装置から出力される距離情報を振動で伝達する場合において、上記装置のどの部分が振動しているのかが、明確にわかること。
【0010】
また、装置から得られた周辺情報を人間の直感に合った伝達手段で伝えられる事。
【0011】
【課題を解決するための手段】
上記目的を達成するために、例えば超音波、赤外線を用いた周辺情報の認識する手段と認識した情報を人に伝達する手段を有する小型な装置を手の甲に装着することによって手で装置を持つ必要がなくなる。
【0012】
また安定して装着するために、上記装置の底面(1)を手の甲の曲面に合わせ装置を湾曲させ、手の甲に密着させる構造にする。
【0013】
振動子を取り付ける際、振動吸収材(5)を介してケース(8)に取り付けることで、取り付け側の振動は、振動吸収材(5)で吸収され、目標とする部位の振動のみを可能としている。
【0014】
また、距離情報を伝達する手段として、上記装置に振動子を1個又は2個以上、手の甲側の親指から小指方向に配置し、例えば認識した距離が遠い場合は小指側の振動子(2d)を振動させ、距離が近い場合は親指側の振動子(2a)を振動させる。それにより、認識した情報に従って振動子を振動させる組み合わせや、振動パターンを変えることにより、人間の直感に合った情報伝達が可能になる。
【0015】
【発明の実施の形態】
本発明では、周辺情報の認識手段として、赤外線よりも指向性が広い超音波を選び、視覚障害者が歩行補助でも使えるように携帯型で実現した。振動子(2)は、小型振動モータを使用。また認識装置(4)を装置固定具(9)で手の甲に固定してある。
【0016】
【実施例】
図1は、本発明の実施例であり、視覚障害者が白杖と併用して歩行補助に本装置を手の甲に装着し歩行している様子を示している。

[Technical field to which the invention belongs]
The present invention relates to a structure of an apparatus for recognizing peripheral information intended for a visually impaired person and an information transmission method.
[0002]
[Prior art]
Conventional recognition devices are made with a structure that is actually used by hand, a glasses-type structure, a pendant-type structure, or a white cane-type structure.
[0003]
The glasses-type structure is heavier than normal glasses and places a burden on the user.
[0004]
In the case of a pendant type structure, it is necessary to turn the body to a place to be recognized, and it is impossible to recognize a fine place. Moreover, when using it with a hand, a hand is blocked and becomes inconvenient.
[0005]
Also, with the white cane structure, the measurement location moves with the white cane each time the white cane is moved, and the measurement location is not determined.
[0006]
In addition, there are sounds and vibrations as means for transmitting the peripheral information. The sound is transmitted by changing the pitch, and the vibration is transmitted by changing the rotation speed.
[0007]
Changes in pitch are often difficult to hear in noises such as crowds, and it takes time to learn the information transmission method for distances based on changes in vibration speed and pitch.
[0008]
[Problems to be solved by the invention]
The problem to be solved is that it can be worn stably without having to hold a peripheral information recognition device by hand.
[0009]
When the distance information output from the device is transmitted by vibration, it is clear which part of the device is vibrating.
[0010]
In addition, the peripheral information obtained from the device can be transmitted by means of transmission suitable for human intuition.
[0011]
[Means for Solving the Problems]
In order to achieve the above object, it is necessary to hold a device by hand by mounting a small device on the back of the hand, which has means for recognizing peripheral information using, for example, ultrasonic waves and infrared rays and means for transmitting the recognized information to a person Disappears.
[0012]
In order to wear it stably, the bottom surface (1) of the device is aligned with the curved surface of the back of the hand so that the device is curved and is in close contact with the back of the hand.
[0013]
When attaching the vibrator, by attaching it to the case (8) via the vibration absorbing material (5), the vibration on the attachment side is absorbed by the vibration absorbing material (5), and only the vibration of the target part can be made. Yes.
[0014]
Further, as a means for transmitting distance information, one or more vibrators are arranged in the above-mentioned apparatus in the direction of the little finger from the thumb on the back side of the hand. For example, when the recognized distance is far, the vibrator on the little finger side (2d) If the distance is short, the vibrator (2a) on the thumb side is vibrated. As a result, it is possible to transmit information that matches human intuition by changing the combination of vibrating vibrators or the vibration pattern according to the recognized information.
[0015]

The vibrator (2) uses a small vibration motor. The recognition device (4) is fixed to the back of the hand with a device fixture (9).
[0016]
【Example】
FIG. 1 is an embodiment of the present invention, and shows a visually impaired person walking with a white walking stick wearing this apparatus on the back of a hand for assisting walking.
[Brief description of the drawings]
FIG. 1 is a view of a visually handicapped person walking together with a white cane while wearing this apparatus on the back of a hand for walking assistance.
FIG. 2 is a view of the apparatus mounted on the back of the hand with the apparatus fixture (9). FIG. 3 is an external view of the apparatus.
