项目摘要

本研究課題は申請書で提案した，「超解像触覚の基盤技術」を1,2年度で確立し，最終的に，「触覚を用いた高精度の記号的情報伝達」という新たな分野を切り拓く内容であった．開発したエッジ刺激法は局所的で鮮明，強烈な振動感覚を，数ミクロン程度の微小振幅で実現するものである．本手法により省パワーで小型の振動子，例えば剛性の高いピエゾ素子などを，触覚ディスプレイに使用し易くする．さらに，触覚ディスプレイ表面を凹凸の無い平面に製作することが可能であり，映像の投影や，デバイスの平面部分への埋め込み等，様々なアプリケーションに応用できる．今日まで「点」の組み合わせで形状を提示していたのに対し，エッジ刺激法は用いて2次元描画のプリミティブである「線」を皮膚に提示し，「線」の組み合わせで形状を作るというコンセプトである．本手法を確立するために，1. 基礎的な特徴と2. メカニズムを調査した．1. では心理物理実験を用いて，感覚強度と触覚像の広がりをいくつかの機械的パラメータに対して調査した．結果から，振動子を隙間なく密に配置し，5-50 Hz 程度，振動面同士は逆位相の振動を用いた場合に最も振動知覚閾値が降下し，強烈な振動感が得られることが明らかとなった．また線を提示する際の，二線弁別域は4.2 mmであった．2. では有限要素変形解析を用いて，エッジ刺激条件下でのヒト皮膚内部のひずみの時空間的な分布を調査した．またヒト指型ひずみセンサを開発し，ひずみの広がりを調査した結果，単一の振動子を用いる刺激法と比較してひずみが振動面の境界に集中して発生しており，局所的な触覚像に寄与していることが分かった．得られた知見を用いて，3×3 の振動子アレイ型触覚ディスプレイを開発し，エッジ刺激による線形状の提示を行った．結果，95%の高い弁別率が得られ，エッジ刺激法を用いた線形状提示の有効性が明らかとなった．

In this study, we proposed a proposal, "Super-contact Technology", which was confirmed in the second year of this study, and the most important one, "contact with high-precision record marks." the content of this new research field is very important. Open the information provided by the Department of Environmental stimulation, and strengthen the sense of vibration. This technique saves the number of small vibrators, such as the high temperature of the vibrator, the contact between the elements, the use of the device, the contact with the surface, the concavity and convexity of the surface, and the projection of the image. In the plane part of the box, the plane part is embedded, and so on, and so on. Today, the point group combines the shape prompt and the second meta-drawing is used to draw the image. The "line" system combines the shape of the system to make sure that the shape is correct, 1. The special features of the base 2. I don't know what to do. 1. The psychophysical device is used, and the sensory strength is similar to that of the machine. The results show that the gap between the vibrators is in a tight configuration, at the level of 5-50 Hz, the vibration surface is the same as the reverse phase vibration machine, and the most effective vibration machine is used to lower the vibration level. If you have a strong sense of vibration, you will have a strong sense of vibration. You will be prompted by a strong sense of vibration, and you will be prompted by a strong sense of vibration. 2. The second line is 4. 2 mm. The distribution of the time and space of the engine under the condition of the stimulation of the finite elements, the distribution of the time and space of the engine under the condition of stimulation, the distribution of the time and space of the engine under the stimulation of the finite elements, the distribution of the time and space of the engine, the distribution of the time and space under the stimulation of the finite elements, the distribution of the time and space of the engine under the condition of stimulation, the results of the experiment, the results of the simulation results, the results of the finite element analysis, the distribution of the time and space of the engine, the distribution of the temperature and the space under the stimulation condition. The contacts sent by the bureau are in contact with each other. You can be informed that you are using the device, the 3 × 3 vibrator is in contact with the device, and the contact shape is used to stimulate the contact line shape to prompt the bank to do so. As a result, 95% of the samples have a high recognition rate, and the lead stimulation method uses the cable shape to indicate that there is an error.
