International Forum on Information and Documentation, 15(4), 32-38. Abstract: The present paper reviews the human factors issues pertinent to the design and use of hypertext documents. It is argued that many of the claims for the new medium are based largely on subjective impressions of its advocates rather than empirical demonstrations of its advantages. Hypertext applications are presented here as a structured subset of an information world that the user can access though an interface. Research relevant to all aspects of reading from screens is reviewed and conclusions for the development of more usable electronic documents are presented. Postscript: Many of the arguments expressed in this paper are dealt with in much more detail in the book Hypertext in Context, by C. McKnight, A. Dillon and J. Richardson.

隨著WWW從單純的資訊傳播管道演進到可作為企業應用的平台，以Web為導向的電腦應用已被企業視為是最具競爭力的武器。基於WWW潛在的龐大商業利益，有越來越多的組織或個人想建立自己的網站，在Internet上發展企業對企業或企業對個人的應用程式。如何設計Web應用系統已成為最重要的課題。然而目前Web程式的開發方法混亂而且沒有標準化，有些建置方式並沒有依循系統分析與設計的原則。簡而言之，我們需要特別的方法與工具來支援超文件系統的開發。所以本研究希望找到一個結構化的步驟與流程來開發以資料庫為核心的超文件應用系統，此外還會製作一套可以支援超文件應用系統設計流程的工具軟體雛形。 / As World Wide Web has evolved from the simple delivery mechanism to a platform for complex business applications, Web-based business computing is already seen as a new competitive business weapon. The potential commercial payoff of WWW results in more and more organizations or people want to construct their own web sites, developing business-to-business or business-to-consumer applications upon the Internet. Designing Web applications has become the serious issue. However, current methods of designing and modeling hypertext applications are still in chaos and keeps ad-hoc nature. Some of the development methods lack serious system analysis and design. In a word, we need special methods and tools to support the development of hypertext applications. Therefore, this research intends to present a structured approach, a step-by-step procedure for developing database-centric hypertext applications. In addition, this paper will implement a tool kit system prototype to support the process of design hypertext applications.

Genre conventions emerge across discourse communities over time to support the communication of ideas and information in socially and cognitively compatible forms. Digital genres frequently borrow heavily from the paper world even though the media are very different. This research sought to identify the existence and form of a truly digital genre. Preliminary results from a survey of user perceptions of the form and content of web home pages reveal a significant correlation between commonly found elements on such home pages and user preferences and expectations of type. Results suggest that the personal home page has rapidly evolved into a recognizable form with stable, user-preferred elements and thus can be considered the first truly digital genre.

(1991) Requirements analysis for hypertext applications: the why, what and how approach. Applied Ergonomics, 22(4), 458-462. Abstract: The present paper presents a simple task description procedure for text usage aimed at supporting human factors input to the specification stage of hypertext and electronic document design. The need for such techniques is outlined and the approach is described in the context of designing hypertext versions of software manuals. Applications and limitations of this procedure are discussed.

Published in: M.Sharples (Ed) Computer Supported Collaborative Writing. (London: Springer-Verlag) 1993. pp 69-86. INTRODUCTION: Psychologists have been taking an increasing interest in the writing process over the last decade and models of human cognition and task behaviour during writing are emerging (see e.g., Hayes and Flower 1980, Sharples et al 1989). Though we are far short of a complete model of this process several basic components have been identified and most theorists allude to these at some stage in their description. For example, it is reckoned (as much from common sense as experimental analysis) that most writing proceeds through a basic sequence of actions from a rough plan through a draft to a revision stage which may occur cyclically until the writer believes the document is ready. Plans can be considered as either detailed or vague, influenced by expectations of the readerâ s knowledge, the typical form of the document being produced and so forth. The drafts may vary from the extremely sketchy to the almost complete depending on the writerâ s experience, knowledge of the subject, preferred writing style etc. and revisions include such acts as minor spell checking, proofreading or complete re-writes.

A number of references in the Human-Computer Interaction literature make the common-sense suggestion that the animated zooming effect accompanying the opening or closing of a folder in the Apple Macintosh graphical user interface aids in a user's perception of which window corresponds to which folder. We examine this claim empirically using two controlled experiments. Although we did not find a statistically significant overall difference resulting from the presence or absence of the zooming effect, a post hoc analysis revealed a highly significant interaction between the experience of users with the Macintosh user interface and the zooming effect. This individual difference suggests that users become attuned to the informational content of the zooming effect with experience.
