We describe two applications that illustrate the idea of computational wear in the domain of document processing. By graphically depicting the history of author and reader interactions with documents, these applications offer otherwise unavailable ...

In this paper, we discuss issues in design and usability of the IBM Computer Sciences Electronic Magazine (CSEM). The CSEM is an interactive multimedia translation of a paper magazine. It contains articles describing Computer Sciences projects at the ...

At EuroPARC, we have been exploring ways to allow physically separated colleagues to work together effectively and naturally. In this paper, we briefly discuss several examples of our work in the context of three themes that have emerged: the need to ...

Collaborations in organizations thrive on communication that is informal because informal communication is frequent, interactive, and expressive. Informal communication is crucial for the coordination of work, learning an organization's culture, the ...

This paper reports on the first of a series of analyses aimed at comparing same room and video-mediated conversations for multiparty meetings. This study compared patterns of spontaneous speech for same room versus two video-mediated conversations. One ...

HCI research at Georgia Tech is found in three cooperating groups: the Engineering Psychology and Experimental Psychology Programs in the School of Psychology, the Center for Human-Machine Systems Research in the School of Industrial and Systems ...

An interface for software that creates a natural environment for engineering graphics students to improve their spatial reasoning and 3D visualization skills is described. The skills of interest involve spatial transformations and rotations, ...

A fisheye lens is a very wide angle lens that shows places nearby in detail while also showing remote regions in successively less detail. This paper describes a system for viewing and browsing planar graphs using a software analog of a fisheye lens. We ...

We describe an interface prototype, the Hierarchical Video Magnifier, which allows users to work with a video source at fine-levels of detail while maintaining an awareness of temporal context. The technique allows the user to recursively magnify the ...

Computer support for group work is a technological innovation receiving considerable attention from developmental researchers. This paper reports the preliminary results from two surveys which assessed user perceived needs for various types of group ...

We studied CAD system users to find out how they use the sophisticated customization and extension facilities offered by many CAD products. We found that users of varying levels of expertise collaborate to customize their CAD environments and to create ...

A belief in the efficacy of imitating face-to-face communication is an unquestioned presupposition of most current work on supporting communications in electronic media. In this paper we highlight problems with this presupposition and present an ...

Increasing use of automation in computer systems, such as advanced cockpits, presents special challenges in the design of user interfaces. The challenge is particularly difficult when automation is intermittent because the interface must support smooth ...

Although computer tools for 3-D design applications are now widely available for use on personal computers, they are unnecessarily difficult to use. Conventions for establishing and manipulating views of 3-D objects require engineering-oriented ...

Models of human-computer interaction (HCI) can provide a degree of theoretical unity for diverse work in computing for users with special needs. Example adaptations for special users are described in the context of both implementation-oriented and ...

Moctec is a set of interactive mockups of an interface for programming search and replace tasks by example. The user guides inference by pointing at relevant features of data.

We formulated a model of visual search by conducting a work flow study and task analysis of art directors as they searched for images to use in an advertisement. The analysis revealed the presence of artistic and image concepts, flexible structures ...

Browser-Soar models the perceptual, cognitive, and motor operators of a user searching for information in an on-line help browser. The model accounts for 90% of the browsing behavior observed in ten episodes. This result suggests that much of browsing ...

This paper investigates to what extent task-oriented user support based on plan recognition is feasible in a highly situation-driven domain like information retrieval (IR) and discusses requirements for appropriate task models. It argues that ...

The motivation for our work is that even though user interface guidelines and style guides contain much useful knowledge, they are hard for user interface designers to use. We want to investigate ways of bringing the human factors knowledge closer to ...

We have augmented user interface objects (i.e. windows, menus, buttons, sliders, ets.) with preconditions that determine their visibility and their enabled/disabled status and postconditions that are asserted when certain actions are performed on the ...

This paper reports on the results of a survey of user interface programming. The survey was widely distributed, and we received 74 responses. The results show that in today's applications, an average of 48% of the code is devoted to the user interface ...
