“An Educational Software for Novices in Basic Pencil Drawing”

Saeko Takagi, Masato Soga, Hirokazu Taki, Fujiichi Yoshimoto, Takashi Shima

Journal of the Institute of Image Electronics Engineers of Japan 32 ( 4 ) 386 - 396 2003年 [査読有り]

A picture is one of important research subjects in order to make our life spiritually rich. Most studies on pictures, however, only propose some substitute functions of actual drawing or painting materials. There is no system that evaluates pictures drawn by users and gives advice about them. We propose an educational software for beginners in basic pencil drawing. Our system receives a subject (motif) data set and an image of a user's sketch and returns advice to the user. The processing is composed of the four functions: feature extraction of motifs, feature extraction of sketches, error identification, and generation and presentation of advice. We developed and experimented a prototype system limited to treat a basic motif and some principal advice. As a result, the validity of the proposed system was confirmed. © 2003, The Institute of Image Electronics Engineers of Japan. All rights reserved.

現在,心を豊かにすることに関する研究がさまざまな分野で行われている.その対象の1 つとして絵画がある.絵画に関する研究は数多く行われているが,実際の画材の代替機能に関するものが主流であり,描かれた絵画を評価し,描き方を指導するシステムは存在しない.そこで,絵画の基本であるデッサンに対象をしぼり,初心者が画用紙に鉛筆で描くデッサンの学習支援システムを提案する.提案システムは,デッサン画像とモチーフ情報とを入力とし,評価およびアドバイスをユーザへ返すものである.その処理は,デッサンの特徴抽出,モチーフの特徴抽出,デッサンの誤りの同定,アドバイスの生成と提示の4 つの機能で行われる.モチーフを皿とジョッキに限定し,構図や形状に関する主要なアドバイス11 項目の処理を行うプロトタイプシステムを作成して試用実験を行い,提案システムの有効性を確認した.

筆者らは,インターネットを介して学習者がライブ映像により天体の観察学習を行うことのできる,リモート望遠鏡システムの構築をこれまで行ってきた.リモート望遠鏡システムを利用すれば,夜の天体のライブ映像を,時差を利用して昼の学校教育の時間帯に見ることができ,天文教育に観察学習をとり入れることが可能になる.本研究では,仮想プラネタリムや仮想望遠鏡,月面インタフェースなど,これまでのリモート望遠鏡システムに比べ,初心者にもわかりやすく,かつ,教育的効果の高いシステムを構築し,その評価を行った.また,授業によるシステムの利用を想定し,多人数でも円滑に望遠鏡の操作が行えるような管理システムを構築した.

絵画教師には,特殊な知識や技能が必要であり、そのため、絵画教師の数は少なく、絵画学習の機会は少ない.しかし,絵画の描き方を教えるようなコンピュータシステムは存在していない.そこで,絵画学習を支援するコンピュータシステムの構築を目的としたプロジェクトが立ち上がった.本論文では,そのプロジェクトのアドバイス生成部について,および,試作システムの評価についてアドバイス生成の視点から述べる.

Remote meteorological observation system and interactive data publishing on web with XML for science education

M. Soga, K. Ninobe, Y. Morimoto, M. Fujigaki, A. Nakajima, H. Tanikawa, M. Miwa, H. Yamada, K. Kato

Proceedings - International Conference on Computers in Education, ICCE 2002 ( Institute of Electrical and Electronics Engineers Inc. ) 860 - 864 2002年 [査読有り]

We developed a remote meteorological observation system and interactive data publishing system on the web. Meteorological sensors collect data and send it to the DBMS. When students retrieve past data on the web, the data are brought with XML. Therefore the data can be transformed by XSLT with XSL style format in accordance with students' demand. The system has flexible GUI by using XML. Also the system can generate some pairs of problem and answer automatically to learn meteorology. This system will contribute to science education.

When we do aerial photography and an environmental research, a remote control helicopter (R/C helicopter) is excellent tool in the next point. For example, the cost of aerial photography and an environmental research work by R/C helicopter are low, also R/C helicopter pilot reservation fee are low price, and free from aviation law in Japan. But, R/C helicopter maneuvering and aerial photographing skills are necessary, and these are difficult to learn. Additionally, if the visibility of R/C helicopter is getting bad when it goes far away, operation is getting difficult. These problems are caused by the badness of autonomous stability on R/C helicopter system. In this study, we propose a new angle detection sensor for 3 axial rotations which is based on the development of the easy and safe steering system for the operation person.

The proposal of the technique of error visualization for a learner's pencil drawing

N. Kajimoto, N. Matsuda, H. Taki, M. Soga, S. Takagi, F. Yoshimoto, T. Shima

In a pencil drawing class, a teacher explains often the differences between a drawing and a motif by many ways
even so, it is difficult for most learners to understand the existence of errors in his/her drawing. When a learner watches the 3D model of his/her drawing from appropriate viewpoints, he/she is immediately aware of the errors. This paper describes the technique of error visualization from a learner's erroneous drawing. We developed a drawing advice system that consists of a 3D model converter from a 2D image and an evaluation function to estimate the effect of the 3D model. We designed a geometrical formula that expresses the relation between the geometrical feature and the error expression in the teacher's advice.

Hue algorithm for plant healthiness monitoring using multispectral infrared camera system

Motoharu Fujigaki, Masafumi Miwa, Atsushi Nakashima, Masato Soga, Hiroki Tanikawa, Koji Kato

Environment preservations of the forest become world-widely close-up. The remote sensing technologies by satellite have been used for observation of the forest. However, the observation system on the ground is also needed because the remote sensing by satellite is seriously hindered by atmospheric phenomena and detailed data are necessary for precise analysis of the state of forest. Therefore we developed a multispectral infrared camera system for plant healthiness monitoring. The infrared camera system has five infrared bandpass filters. A hue is defined from the five infrared images. We performed several experiments to confirm that the hue changes according as the plant healthiness decline. In this paper, we propose a plant healthiness evaluation method by detecting hue changes with time. Experimental results of observation of hue changes of a plant through a day using the multispectral infrared camera system are shown. The results show that hue in healthiness parts of plants are more stable than in weak pans when the circumambient conditions such as the sunshine condition are changed.
