【０００９】

【００１４】
【発明の実施の形態】
本実施の形態の概要
ここでは、６点点字出力機能を有した指装着型６指点字情報提示装置について説明する。
【００１５】
本実施の形態では、視覚障害者や盲ろう者がパーソナルコンピュータなどの情報機器から何時でも、何処でも点字情報を入手するために用いる指装置型６指点字情報提示装置を提供する。６指点字とは、点字を構成する６個の点それぞれを６本の指に対応させる点字提示手法であり、６本の指に与える触覚刺激の組み合わせにより点字１文字を表現する。
【００１６】
本実施の形態は、６点点字情報を提示する機能を有する情報機器が、６本の指の皮膚に異なった触覚刺激を直接あるいは間接的に与える装置を提供する。しかし、６本の指に装着した全ての触覚刺激素子が同じ刺激を指に与えた場合、刺激する指の組み合わせによっては、どの指が刺激されているか認識できなくなる現象が生じる。そこで、本実施の形態では、刺激されている指の組み合わせの誤認識を軽減させるため、６本の指それぞれに異なった感覚の触覚刺激を与える指装着型６点点字情報提示装置を提供する。
【００１７】
本実施の形態の詳細な説明
以下、図面を参照しながら、本実施の形態を詳細に説明していく。
【００１８】
図１は、触覚刺激素子１を指に装着した状態の俯瞰図を示す。触覚刺激素子１は、駆動回路２からの駆動信号によって異なった触覚刺激を指に与える。６本の指に取り付けた触覚刺激素子１それぞれが異なった刺激を指に与える。指に触覚刺激を与える触覚刺激素子１には、
▲１▼振動する触覚刺激を与える振動型触覚刺激素子（以下、触覚刺激素子Ａという）、
▲２▼装着した指の皮膚へ直線的な仮現運動刺激を与える触覚刺激素子（以下、触覚刺激素子Ｂという）、
▲３▼指の皮膚に直接撫でるような刺激を与える触覚刺激素子（以下、触覚刺激素子Ｃという）がある。
【００１９】
これらの刺激素子の動作条件を変えることにより、どの指が刺激されているかを利用者が知覚し易くなる。また、触覚刺激素子Ａ，触覚刺激素子Ｂ，触覚刺激素子Ｃを６本の指それぞれに配置するなど、指ごとに異なった触覚刺激素子を装着することによっても、どの指が刺激されているかを利用者が知覚し易くなる。
【００２０】
触覚刺激素子Ａには、図２に示すように回転軸３から一定の距離Ｌに錘４を設置し、駆動モータ５の回転によって振動刺激を発生させる回転型振動刺激素子と、図３に示すように先端に取り付けた錘８が微小移動距離Ｌ1を往復運動する往復運動型振動刺激素子がある。なお、図３において、９は電磁石、１０はバネ、１１は支点である。
【００２１】
図２に示した回転型振動刺激素子、あるいは図３に示した往復運動型振動刺激素子による触覚刺激素子Ａを取り付けた指に対し、異なった触覚刺激を与えるには、それぞれの触覚刺激素子Ａを異なった振動周波数もしくは振幅で動作させればよい。
【００２２】
図４は、異なった触覚刺激を与える指と振動周波数の関係を示す。図２に示した回転型振動刺激素子の場合、駆動モータ５の回転数をそれぞれ周波数ｆ１〜ｆ６で回転させることにより、指１３ａ〜１３ｆに異なった周波数の振動刺激を与えることができる。また、触覚刺激強度を変化させる場合は、回転軸３に取り付けた錘４の質量・形状、回転軸３と錘４の重心との間の距離Ｌの組み合わせを変えることにより触覚刺激強度を変化させることができる。
【００２３】
他方、図３に示す往復運動型振動刺激素子の場合、錘８を往復運動させるための電磁石９の駆動周波数を各指ごとに変えることにより、異なった周波数の振動刺激を指に与えることができる。また、刺激強度を変えるには、錘８の質量・形状、支点１１からの距離Ｌ2、電磁石９の磁力に抗する反力を発生させるバネ１０のバネ定数のいずれかを変化させることにより、異なった触覚刺激を指に与えることができる。
【００２４】
このように、回転型振動刺激素子または往復運動型振動刺激素子を用いた触覚刺激素子Ａが、各指に対し振動周波数や刺激強度など異なった触覚刺激を与えることで、どの指が刺激されているかを利用者が知覚し易くなる。
【００２５】
触覚刺激素子Ｂは、指の表面を叩くような刺激を順次指に与えることにより、指の表面に直線的な仮現運動刺激を作用する触覚刺激素子である。６本の指に与える仮現運動刺激の速度や指の皮膚を叩く強さを変化させることにより、どの指が刺激されているか利用者が知覚し易くなる。触覚刺激素子Ｂは、上下移動量Ｌａ，Ｌｂ，Ｌｃの刺激子１５ａ，１５ｂ，１５ｃを図５のように配置し、刺激子１５ａ，１５ｂ，１５ｃの連続した協調動作によって仮現運動を指に与える触覚刺激素子である。図５において、１６は打ち込み量を、１７ａ〜１７ｃはバネを示す。
【００２６】
なお、図５に示した例では、刺激子１５ａ，１５ｂ，１５ｃを３個配置したが、仮現運動が知覚できる範囲内において刺激子の個数に制限はない。
【００２７】
図６は、図５の如く３個配列した刺激子１５ａ〜１５ｃの駆動信号波形を示す。仮現運動を発生させるため、それぞれの刺激子１５ａ，１５ｂ，１５ｃの動作を制御する駆動信号１８ａ，１８ｂ，１８ｃは、基準となる駆動信号１８ａに対し、遅延時間１９ａ，１９ｂだけ遅れさせる。触覚刺激素子Ｂを装着した利用者が仮現運動を認識する範囲内において、遅延した駆動信号で触覚刺激素子を駆動させることにより、仮現運動速度を変化させることができる。
【００２８】
また、上下する刺激素子１５ａ，１５ｂ，１５ｃが皮膚１３に対する打ち込み量１６や打ち込み速度を変化させるバネ１７ａ，１７ｂ，１７ｃのバネ定数を変化させることにより、触覚刺激強度を変えることができる。触覚刺激素子Ｂの場合、６本の指それぞれに取り付けた触覚刺激素子の駆動信号１８ａ，１８ｂ，１８ｃ、打ち込み量１６、打ち込み速度を変化させるバネ１７ａ，１７ｂ，１７ｃの条件を変えることにより異なった触覚刺激を与えることができる。
【００２９】
図７に示す触覚刺激素子Ｃは、指の皮膚１３上を直線的に撫でるような刺激を与える触覚刺激素子である。触覚刺激素子Ｃの場合、らせん状軸２０の回転方向によって直線的に往復移動する刺激子２１の移動速度Ｖや、皮膚１３に対して撫でるような触覚刺激を与える刺激子２１の材質を柔らかい材質，硬い材質，粘度の高い材質・低い材質など、刺激子２１の物理的な特性を変えることにより、どの指が刺激されているかを利用者が知覚し易くなる。
【００３０】
【発明の効果】
以上説明した通り本発明によれば、複数の指に装着した触覚刺激素子がそれぞれの指に対して異なった触覚刺激を与えることにより、どの指が刺激されているかを利用者が知覚し易くなる。
【００３１】
また、本発明によれば、触覚刺激の認識を妨げる要因が多い屋外での使用でも６点点字が認識し易くなるので、何時でも何処でも、デジタル放送受信機，パーソナルコンピュータ，ワードプロセッサなどの情報機器から認識し易い６点点字情報等の入手が可能となる。

Therefore, in this embodiment, in order to reduce misrecognition of a combination of stimulated fingers, a finger-worn 6 Braille information presentation device that provides tactile stimulation with different sensations to each of the six fingers is provided.
[0017]
Detailed description of the present embodiment Hereinafter, the present embodiment will be described in detail with reference to the drawings.
[0018]
FIG. 1 shows an overhead view of a state in which the tactile stimulation device 1 is attached to a finger. The tactile stimulation element 1 gives different tactile stimulations to the finger according to the drive signal from the drive circuit 2. Each of the tactile stimulation elements 1 attached to the six fingers gives different stimulations to the fingers. The tactile stimulation element 1 that applies tactile stimulation to the finger includes:
(1) A vibration-type tactile stimulation element (hereinafter referred to as a tactile stimulation element A) that gives a vibrating tactile stimulation,
(2) A tactile stimulating element (hereinafter referred to as a tactile stimulating element B) that gives a linear apparent movement stimulus to the skin of a finger that is worn.
(3) There is a tactile stimulation element (hereinafter referred to as a tactile stimulation element C) that gives a stimulus such as stroking the finger skin directly.
[0019]
By changing the operating conditions of these stimulating elements, the user can easily perceive which finger is being stimulated. Also, which finger is stimulated by attaching different tactile stimulation elements for each finger, such as placing the tactile stimulation element A, the tactile stimulation element B, and the tactile stimulation element C on each of the six fingers. It becomes easier for the user to perceive.
[0020]
As shown in FIG. 2, the tactile stimulation element A has a rotary vibration stimulating element in which a weight 4 is installed at a fixed distance L from the rotating shaft 3 and a vibration stimulation is generated by the rotation of the drive motor 5; Thus, there is a reciprocating vibration stimulating element in which the weight 8 attached to the tip reciprocates a minute movement distance L 1 . In FIG. 3, 9 is an electromagnet, 10 is a spring, and 11 is a fulcrum.
[0021]
In order to give different tactile stimuli to the finger attached with the tactile stimulating element A by the rotary vibration stimulating element shown in FIG. 2 or the reciprocating vibration stimulating element shown in FIG. May be operated at different vibration frequencies or amplitudes.
[0022]
FIG. 4 shows the relationship between the finger giving different tactile stimuli and the vibration frequency. In the case of the rotary vibration stimulating element shown in FIG. 2, vibration stimuli of different frequencies can be applied to the fingers 13a to 13f by rotating the rotational speed of the drive motor 5 at frequencies f1 to f6, respectively. When changing the tactile stimulus intensity, the tactile stimulus intensity is changed by changing the combination of the mass and shape of the weight 4 attached to the rotating shaft 3 and the distance L between the rotating shaft 3 and the center of gravity of the weight 4. be able to.
[0023]
On the other hand, in the case of the reciprocating vibration stimulating element shown in FIG. 3, by changing the driving frequency of the electromagnet 9 for reciprocating the weight 8 for each finger, vibration stimuli of different frequencies can be given to the finger. . In order to change the stimulation intensity, by changing any of the mass and shape of the weight 8, the distance L 2 from the fulcrum 11, and the spring constant of the spring 10 that generates a reaction force against the magnetic force of the electromagnet 9, Different tactile stimuli can be applied to the finger.
[0024]
In this way, the tactile stimulation element A using the rotary vibration stimulation element or the reciprocating vibration stimulation element gives different tactile stimulations such as vibration frequency and stimulation intensity to each finger, which finger is stimulated. It becomes easier for the user to perceive.
[0025]
The tactile stimulation element B is a tactile stimulation element that applies a linear apparent motion stimulus to the surface of the finger by sequentially giving the finger a stimulus that strikes the surface of the finger. The user can easily perceive which finger is being stimulated by changing the speed of the apparent motion stimulus given to the six fingers and the strength of tapping the finger skin. The tactile stimulation element B arranges the stimulators 15a, 15b, and 15c of the vertical movement amounts La, Lb, and Lc as shown in FIG. 5, and the apparent movement is performed by the continuous cooperative operation of the stimulators 15a, 15b, and 15c. It is a tactile stimulation element to be applied. In FIG. 5, 16 indicates the driving amount, and 17a to 17c indicate springs.
[0026]
In the example shown in FIG. 5, three stimulators 15a, 15b, and 15c are arranged. However, the number of stimulators is not limited within a range in which the apparent motion can be perceived.
[0027]
FIG. 6 shows drive signal waveforms of the three stimulators 15a to 15c arranged as shown in FIG. In order to generate the apparent movement, the drive signals 18a, 18b, and 18c for controlling the operations of the respective stimulators 15a, 15b, and 15c are delayed by the delay times 19a and 19b with respect to the reference drive signal 18a. The apparent movement speed can be changed by driving the tactile stimulation element with a delayed drive signal within a range in which the user wearing the tactile stimulation element B recognizes the apparent movement.
[0028]
Further, the intensity of tactile stimulation can be changed by changing the spring constants of the springs 17a, 17b, and 17c that change the driving amount 16 and the driving speed of the stimulating elements 15a, 15b, and 15c moving up and down. In the case of the tactile stimulation element B, the driving signals 18a, 18b, 18c of the tactile stimulation elements attached to the six fingers, the driving amount 16, and the conditions of the springs 17a, 17b, 17c that change the driving speed are changed. A tactile stimulus can be applied.
[0029]
The tactile stimulation element C shown in FIG. 7 is a tactile stimulation element that gives a stimulus such as stroking the finger skin 13 linearly. In the case of the tactile stimulating element C, the moving speed V of the stimulator 21 that reciprocally moves linearly according to the rotation direction of the spiral shaft 20 and the material of the stimulator 21 that gives tactile stimuli such as stroking the skin 13 are soft materials. By changing the physical characteristics of the stimulator 21, such as a hard material, a material with high viscosity, or a material with low viscosity, the user can easily perceive which finger is being stimulated.
[0030]
【The invention's effect】
As described above, according to the present invention, the tactile stimulation elements attached to a plurality of fingers give different tactile stimulations to each finger, so that the user can easily perceive which finger is being stimulated. .
[0031]
In addition, according to the present invention, it becomes easy to recognize six-point braille even when used outdoors, where there are many factors that hinder recognition of tactile stimuli. Therefore, information equipment such as digital broadcast receivers, personal computers, word processors, etc. It becomes possible to obtain information such as 6-point braille information that is easy to recognize.
