In order to get students in engineering courses to acquire a good command of English, a coursework named “English for Engineers” has been offered to senior students in the department of mechanical engineering of Mie University. The authors place much value on the coursework from the viewpoints of acquiring the ability of (1) accurate pronunciations in accordance with phonetic symbols, and (2) a series of translations from a word-for-word translation to a free one. To make the coursework more effective, the authors have developed an e-learning system. The system supports teachers in engineering departments who are normally non-professionals in English education. The results showed that the proposed system is effective for comprehending the importance on the above-mentioned two viewpoints.
There are motor point maps as index of stimulation points to move each muscle for functional electrical stimulation (FES). However we'll usually have to search detailed motor points by trial and error when arranging electrodes since individual differences are large. In this research, we developed a system aids searching motor points of fingers and wrist muscles. It contains 12 × 10 electrodes which cover a forearm and sensors which catch movement of each finger and wrist. It chooses a pair of electrodes in order and stimulates a subject. When the response was measured, it records the response movement and the position of electrode pair. As a result, we obtained the generated motor point map.

The objective of this study is to develop a novel finger-tactile interface employing “active wheel”: the wheel is rotated around its central axis, and the central axis is swiveled around in a vertical axis with any speeds and duration times. The swivel and the rotation, respectively, result in the direction and the speed of slippage on finger-pad skin. The peripheral surface of the wheel provides the slippage, the skin-stretch, the curvature and the edge stimulus to the finger-pad skin, where the push-in quantity of the wheel peripheral surface into skin is considered to be important for the slippage perception and to be dependent on the wheel thickness. Therefore, for improving the slippage perceptual characteristics, we examined an effect owing to a wheel thickness factor, of which levels are a disc or a drum. In addition, we introduced raised-dots on the wheel peripheral surface: the raised-dot creates a sinkage. The dotted wheel rotation provides a dislocation stimulus of the sinkage, which is expected to be effective for slippage perception. Thus, in order to determine the slippage perceptual characteristics, and to select the better wheel configurations with respect to the wheel-thickness and the raised-dots, psychophysical experiments were conducted by introducing four kinds of wheels: “Dot‣Drum”, “Dot‣Disc”, “Smooth‣Drum” and “Smooth‣Disc” wheel. As a result, we found the followings: (1) Dot‣Drum, i.e., the thick wheel with raised dots, is better than the other three wheels for the systematic errors not for the random errors in length perception, (2) Dot‣Drum and Dot‣Disc, i.e., the two dotted wheels are better than the other two smooth wheels for the random errors not for the systematic errors in direction perception.

ビデオオンデマンド講義配信システムでは,学生は遠隔から,あるいは自由な時間に講義シーンを視聴できる.これにより,復習や欠席のリカバーなどの形で,実際の講義を補完することができ,大きな教育効果が期待できる.昨年度は,デジタルスチルカメラ画像を利用して,高解像度を確保しながら,デジタルビデオカメラ画像から指示棒動作のみを抽出して,これをデジタルスチルカメラ画像に重畳する方式を開発し,有効性を確認した.しかしながら,デジタルスチルカメラ画像における文字情報のコントラストの低下,さらには講師映像がデジタルスチルカメラ画像とは別の小動画として表示されていることによる臨場感の欠如などの課題が残っていた.今年度は,この方式についてさらに検討を進め,実際の講師映像を電子ファイルによって生成されたパソコン画面に重ね合わせるシステムを開発した.これにより,低容量でありながら,電子ファイル固有の画像の高精細さを保存し,しかも講義の臨場感(一種の仮想現実感)を伝えることのできる,新しい講義映像形態を実現することができる.さらに,本システムを用いて,実際の講義との比較実験を行った.その結果,理解度を確認するための小テストでは本システムは実際の講義と同等以上とあった.さらに,文字は十分に読め,講師の動きもある程度は伝わってきた,との回答を得た.さらに,利用方法についても,期待したとおり,講義を補完する形での使用について高い支持を得た.
