Workspace awareness is knowledge about others’ interaction with a shared workspace. Groupware systems provide only limited information about other participants, often compromising workspace awareness. This paper describes a usability study of several widgets designed to help maintain awareness in a groupware workspace. These widgets include a miniature view, a radar view, a multiuser scrollbar, a glance function, and a “what you see is what I do ” view. The study examined the widgets’ information content, how easily people could interpret them, and whether they were useful or distracting. Observations, questionnaires, and interviews indicate that the miniature and radar displays are useful and valuable for tasks involving spatial manipulation of artifacts.

Kinetic typography – text that uses movement or other temporal change – has recently emerged as a new form of communication. As we hope to illustrate in this paper, kinetic typography can be seen as bringing some of the expressive power of film – such as its ability to convey emotion, portray compelling characters, and visually direct attention – to the strong communicative properties of text. Although kinetic typography offers substantial promise for expressive communications, it has not been widely exploited outside a few limited application areas (most notably in TV advertising). One of the reasons for this has been the lack of tools directly supporting it, and the accompanying difficulty in creating dynamic text. This paper presents a first step in remedying this situation – an extensible and robust system for animating text in a wide variety of forms. By supporting an appropriate set of carefully factored abstractions, this engine provides a relatively small set of components that can be plugged together to create a wide range of different expressions. It provides new techniques for automating effects used in traditional cartoon animation, and provides specific support for typographic manipulations.

Kinetic (dynamic) typography has demonstrated the ability to add significant emotive content and appeal to expressive text, allowing some of the qualities normally found in film and the spoken word to be added to static text. Kinetic typography has been widely and successfully used in film title sequences as well as television and computer-based advertising. However, its communicative abilities have not been widely studied, and its potential has rarely been exploited outside these areas. This is partly due to the difficulty in creating kinetic typography with current tools, often requiring hours of work to animate a single sentence. In this paper, we present the Kinedit system, a basic authoring tool that takes initial steps toward remedying this situation and hence promoting exploration of the communicative potential of kinetic typography for personal communication. Kinedit is informed by systematic study and characterization of a corpus of examples, and iterative involvement and validation by designers throughout the development process. We describe the tool and its underlying technology, usage experiences, lessons learned, and next steps.

This video illustrates three distortion-oriented displays as novel ways of providing awareness of others within groupware. These displays employ magnification lenses and fisheye view techniques to show global context and local detail within a single window, providing both peripheral and detailed awareness of other participants’ presence, location, and actions. The head-up lens uses a transparent interface, showing local detail in the foreground and an overview in the background. The offset lens allows a person to magnify a region of the overview. Finally, the fisheye text viewer displays multiple focal points, one for each participant in the conference.

A month-long quasi-experiment was conducted using a distributed team responsible for modeling, simulation, and analysis. Six experiments of three different time durations (short, medium, and long) were performed. The primary goal was to discover if synchronous collaboration capability through a particular application improved the ability of the team to form a common mental model of the analysis problem(s) and solution(s). The results indicated that such collaboration capability did improve the formation of common mental models, both in terms of time and quality (i.e., depth of understanding), and that the improvement did not vary by time duration. In addition, common mental models were generally formed by interaction around a shared graphical image, the progress of collaboration was not linear but episodic, and tasks that required drawing and conversing at the same time were difficult to do.

Group awareness has become important in improving the usability of real-time, distributed, collaborative writing systems. However, the current set of implemented awareness mechanisms is insufficient in providing extensive and comprehensive awareness in collaborative authoring. Certainly, current mechanisms, such as telepointers and multi-user scrollbars, have contributed greatly in providing awareness support in collaborative writing. Yet, given the shortcomings of these mechanisms and the difficulty in providing rich interaction found in face-to-face collaboration, much more support needs to be provided for group awareness during authoring. This research extends the pool of all known awareness mechanisms (including those that have been discovered before but have yet to be implemented).

this paper we propose that distortion-oriented visualization techniques are a natural candidate for providing collaborative workspace awareness. In single-user systems distortion-oriented visualizations such as magnification-lenses, zooming functions and fish-eye views ease the transition between high-levels of detail in a local area of interest and the global context of the information space. In groupware environments they can be used to provide tailorable levels of awareness of coworkers while maintaining a focus on the local region of personal work. Our previous work (Greenberg et al., 1996a; Greenberg et al., 1996b; Greenberg et al., 1996c) has demonstrated several styles of distortion-oriented workspace awareness using point systems, but it has fallen short of evaluation. In this paper we describe a fully functional and robust distortion-oriented multi-user editor called DOME,and

Fisheye views are well-known visualisation techniques that provide a sense of global context as well as local detail. We have developed a prototype system that differs from traditional fisheye views in two ways. First, the user can create, edit, and move objects in the fisheye workspace. Second, our system is groupware, so several people can see and manipulate the data at the same time, using individual focal points. These differences raise usability questions concerning interactive fisheye views for groupware. These include a user's difficulty in maintaining layout fidelity as objects and focal points change, and the difficulty of showing where others are working and what they can see.

This paper describes a prototype system that displays synchronous workplace awareness information using the ambient technology paradigm. It focuses on making people aware of the nature and volume of interactions that have taken place within a workgroup. The visualisation uses simple graphics based on a maritime flags metaphor, is displayed in the Windows Active Desktop and is designed to be as nonintrusive as possible. The information used in the visualisation is drawn from a database which stores information about the type and frequency of interactions by the users of the co-operative environment. The system uses lightweight technologies and it should be easy to add features to support delivery of the information to standard client applications, smart boards, PDA’s and mobile phones.
