An e-Mail Environment with handwriting using the handsdraw digital ink format
Systems and Computers in Japan, 2002Co-Authors: Naoki Kato, Hiroshi Tanaka, Masaki NakagawaAbstract:This paper proposes a handwriting-based e-Mail Environment system, including the HandsDraw format, whose facilities include the reading and writing of handwritten massages, their transmission and reception, annotations or comments by recipients, confirmation of the author and time of writing, and reproduction of handwriting. The system has a user interface which is friendly even to a beginner, and can handle more expressive massages on the Internet. The system is regarded as an advanced mobile communication terminal of the kind which has been fashionable recently. Considering the advantages and disadvantages of pen input, encircling (lasso) selection and a button interface are used for dialogue. Users' opinions (collected by questionnaires, on the Internet, and from laboratory use of the system for 2 1/2 years) confirm all of the functions of the system. Some respondents have suggested the conversion of handwritten characters to a type font (rather than sending them directly) by using the character-recognition facility in this system. © 2002 Wiley Periodicals, Inc.

E-Mail Environment with Handwriting Using Digital Ink Format 'HandsDraw'
2001Co-Authors: Naoki Kato, Hiroshi Tanaka, Masaki NakagawaAbstract:あらまし 本論文は,手書きメッセージの読み書き,送受信,重ね書き,筆記者・筆記時刻確認,筆記再生など の機能を有する手書き電子メール環境について述べる.我々は,初心者にも自然な手書きを UIに採用し,簡単 に表現豊かなメッセージをインターネット上で送受信できるシステムを実現した.本システムは手書きメッセー ジが送受信できる点で,近年急成長している携帯型情報通信端末に先行するものである.更に,手書きの筆跡や 図形,コード文字を表現できるように提案したフォーマット HandsDrawに従い,手書きのメッセージを読み書 き,送受信する機能はもちろん,受信メールへの上書き,筆記者・筆記時刻確認機能,そして,筆記再生機能を 提供する.対話技法としては,ペン入力の良さを生かした囲み選択と,ペン入力の弱点を解決したボタンインタ フェースを採用した.本システムを実際に使用してもらった上でアンケート調査を行い,また,2年半にわたる インターネットでの公開や研究室内での使用によって多くの意見を収集した.その結果,提供するすべてに機能 に対して総じて肯定的な意見が得られた.その一方で,手書きの文字をそのまま送りたくないとの意見も得られ, 文字認識機能の必要性が示された. キーワード ペン入力,手書き,電子メール,インクフォーマット

A Comparative Study of Distributed Learning Environments on Learning Outcomes
Information Systems Research, 2002Co-Authors: Maryam Alavi, George M. Marakas, Youngjin YooAbstract:Advances in information and communication technologies have fueled rapid growth in the popularity of technology-supported distributed learning (DL). Many educational institutions, both academic and corporate, have undertaken initiatives that leverage the myriad of available DL technologies. Despite their rapid growth in popularity, however, alternative technologies for DL are seldom systematically evaluated for learning efficacy. Considering the increasing range of information and communication technologies available for the development of DL Environments, we believe it is paramount for studies to compare the relative learning outcomes of various technologies.In this research, we employed a quasi-experimental field study approach to investigate the relative learning effectiveness of two collaborative DL Environments in the context of an executive development program. We also adopted a framework of hierarchical characteristics of group support system (GSS) technologies, outlined by DeSanctis and Gallupe (1987), as the basis for characterizing the two DL Environments.One DL Environment employed a simple e-Mail and listserv capability while the other used a sophisticated GSS (herein referred to as Beta system). Interestingly, the learning outcome of the e-Mail Environment was higher than the learning outcome of the more sophisticated GSS Environment. The post-hoc analysis of the electronic messages indicated that the students in groups using the e-Mail system exchanged a higher percentage of messages related to the learning task. The Beta system users exchanged a higher level of technology sense-making messages. No significant difference was observed in the students' satisfaction with the learning process under the two DL Environments.

Issues in enterprise e-Mail management
IEEE Communications Magazine, 1996Co-Authors: Deokjai Choi, Taesang Choi, A. TangAbstract:The existing e-Mail management standards are all proposed for specific e-Mail technologies. Unless everyone agrees on a common backbone e-Mail technology and its management, it will be difficult to tackle enterprise e-Mail management. The authors provide management solutions to the following problems in an enterprise e-Mail Environment: message transfer agents (MTAs) and e-Mail gateway monitoring; e-Mail tracking; and congestion management. When an e-Mail manager evaluates an e-Mail protocol, it should examine how the protocol tackles these problems.
