近年,タブレット端末利用の需要が高まっており,市場も拡大傾向にある.しかし,タブレット端末を使用する際に不便だと感じたことの調査では,文字入力がしにくいという回答が多数存在する.市場で流通している入力装置では,価格や可搬性の低下といった問題があるためAR技術とタブレットPC内臓のカメラを用いた入力装置を提案する.

本稿では阿波踊りの動作の定量評価の一手法を提案する.我々の大学がある徳島県には伝統的な踊りとして「阿波踊り」がある.阿波踊りの基本動作は,手と足の調和,2拍子のリズムに合わせるといったコツがあるが,踊り手の微妙な手足の動き,重心位置の変化,リズム等の違いにより見た人の受ける印象は異なる.本稿では阿波踊りの基本動作をモーションキャプチャにより,計算機に取り込み,踊りのうまさを定量化する手法を提案する.これは,取得したデータ波形とお手本となるデータ波形を比較することで,動作特徴を抽出し,踊りのうまい,へたの評価を行うものである.本稿では更に踊りの名手との比較により,阿波踊りを得点化する実験を示し,本手法の有効性を検証する.

"AWA ODDRI" dance is one of the traditional dance festival of Tokushima Prefecture in Japan. Basic operation of "AWA ODORI" dance needs harmony of hands and legs, and the rhythm of duple time, but it is not possible that the beginners do these actions completely. We have already developed the method of quantifying evaluation of the skill of "AWA ODORI" dance. But the three dimensional movements are not able to be evaluated by image squences. In this paper, the authors proposed a method of quantifying evaluation of the skill of "AWA ODORI" dance by using the three dimensional data. In this method, the image sequence of dance scenes is obtained by a stereo camera with a simple of structure. The dynamics of motion is detected by three dimensional data calculated by the stereo camera. The input data and model data of excellent dancers are compared. In this paper, we describe the algorithm of quantifying evaluation of the skill using the stereo view and show some experimental results obtained by using a simple experimental system to verify effectiveness of the proposed method.

In this paper, we propose a method for recognizing phoneme by using a sequence of color lip images. The mouth images are obtained in series by using the color camera set at the front of the face. First, among the sequence of the images, each object image for processing is detected by using mouth movement information. Next step, in each image, the mouth region is detected by the color information. Then, the four shapes which are outside line of lip, the inside line of lip, the tangue and the center line of lip are extracted by using the change in distribution of gray level. Finally, the recognition of phoneme is carried out by the method based on the subspace method. As the training, the subspace method needs the 20 features extracted from the above four shapes. In this paper, the authors describe the results of the experiments which were performed to demonstrate the effectiveness of the proposed method.

As well known, human sensing is useful for our life. But, the development of the human sensing system is not easy, because the shape and the movement of human are complicated and Indistinct; the environment of obtaining image is not always constant and so on. We have developed some methods of identifying individuals using facial image, counting passing people, observing of human behave and so on. In this paper, human sensing and its applications are introduced. In addition, examples of application are shown.
