In this paper, we describe a range of audio problems that impact the effectiveness of audio conferences and detail the solutions we have devised to address these problems. We conducted an audio quality assessment to determine how differences in quality impact audio clarity, a remote person's experience connecting to a conference room, and social presence. Based on the results of this assessment, we examine the costs and benefits of increasing audio fidelity with respect to the network resources needed to support high-fidelity audio conferencing.

Out-of-band communication during audio conferences can improve the effectiveness of distributed meetings. It provides a means for people to privately consult with one another, supports breakout sessions, and allows individuals to resolve problems without interrupting the discussion. Conversely, off-topic chat and poorly timed interruptions can degrade meeting effectiveness. We considered these trade-offs in adding a private text chat capability and a novel, multi-channel voice chat feature to the Meeting Central collaboration suite. In this paper, we explain the motivation behind adding these features and then describe our initial implementation, the usability and field testing we conducted, and the changes that we made as a result of that user research.

Using Office Central, remote workers can "advertise" their presence in public spaces within offices, such as break areas, lounges or cafeterias. The design concept is to encourage informal, unplanned interactions between remote workers and those who pass through the public spaces. In this prototype installation at the Computer History Museum in Mountain View, CA, we set up a lounge area with an Office Central picture window display (Figure 1). The local people in the lounge, wearing RFID tags for identification, could chat informally with remote people using a high-fidelity, CD-quality audio channel. The virtual meeting places included audio and video content, designed to be experienced jointly by the local and remote people. Some content was also tailored to the local people, updating as they approached the picture window display.

The Meeting Central prototype is a suite of collaboration tools designed to support distributed meetings. The tools' minimalist design provides only those features that have the most impact on distributed meeting effectiveness. The collaboration suite is built on top of a distributed, extensible, and scalable framework.

Begole, James, Tang, John C., Smith, Randall B. and Yankelovich, Nicole (2002): Work rhythms: analyzing visualizations of awareness histories of distributed groups. In: Churchill, Elizabeth F., McCarthy, Joe, Neuwirth, Christine and Rodden, Tom (eds.) Proceedings of the 2002 ACM conference on Computer supported cooperative work November 16 - 20, 2002, New Orleans, Louisiana, USA. pp. 334-343.

We examined records of minute-by-minute computer activity coupled with information about the location of the activity, online calendar appointments, and e-mail activity. We present a number of visualizations of the data that exhibit meaningful patterns in users' activities. We demonstrate how the patterns vary between individuals and within individuals according to time of day, location, and day of the week. Some patterns augment the schedule information found in people's online calendars. We discuss applications for group coordination (especially across time zones) plus opportunities for future research. In light of the popularity of instant messaging, this research identifies some of the benefits and privacy risks associated with the uses of online presence and awareness information.

Tang, John C., Yankelovich, Nicole, Begole, James, Kleek, Max Van, Li, Francis and Bhalodia, Janak (2001): ConNexus to Awarenex: Extending Awareness to Mobile Users. In: Beaudouin-Lafon, Michel and Jacob, Robert J. K. (eds.) Proceedings of the ACM CHI 2001 Human Factors in Computing Systems Conference March 31 - April 5, 2001, Seattle, Washington, USA. pp. 221-228.

We explored the use of awareness information to facilitate communication by developing a series of prototypes. The ConNexus prototype integrates awareness information, instant messaging, and other communication channels in an interface that runs on a desktop computer. The Awarenex prototype extends that functionality to wireless handheld devices, such as a Palm. A speech interface also enables callers to make use of the awareness information over the telephone. While the prototypes offer similar functionality, the interfaces reflect the different design affordances and use context of each platform. We discuss the design implications of providing awareness information on devices with varying interface and network characteristics.

Proceedings of the ACM CHI 95 Human Factors in Computing Systems Conference May 7-11, 1995, Denver, Colorado. pp. 369-376.

SpeechActs is an experimental conversational speech system. Experience with redesigning the system based on user feedback indicates the importance of adhering to conversational conventions when designing speech interfaces, particularly in the face of speech recognition errors. Study results also suggest that speech-only interfaces should be designed from scratch rather than directly translated from their graphical counterparts. This paper examines a set of challenging issues facing speech interface designers and describes approaches to address some of these challenges.

The Envoy Framework addresses a need for computer-based assistants or agents that operate in conjunction with users' existing applications, helping them perform tedious, repetitive, or time-consuming tasks more easily and efficiently. Envoys carry out missions for users by invoking envoy-aware applications called operatives and inform users of mission results via envoy-aware applications called informers. The distributed, open architecture developed for Envoys is derived from an analysis of the best characteristics of existing agent systems. This architecture has been designed as a model for how agent technology can be seamlessly integrated into the electronic desktop. It defines a set of application programmer's interfaces so that developers may convert their software to envoy-aware applications. A subset of the architecture described in this paper has been implemented in an Envoy Framework prototype.

With the advent of multimedia technology, hypertext has evolved into hypermedia, in which the elements that are linked together can include animations, video clips, music recordings, and database queries. The critical hypertext function of link traversal must undergo a parallel evolution to support the dynamic aspects of these new types of information. This paper introduces the concept of active anchors within dynamic information and explores the design issues involved in linking to active anchors. Scenarios from our hypermedia system, Intermedia, illustrate the use of active anchors in a university setting. General conclusions recommend characteristics that may facilitate the implementation of this concept in other hypermedia systems.

Based on three years of user feedback, a design team at IRIS embarked on a project to enhance Intermedia to better support small groups of collaborators, particularly those involved with document review and revision. Towards this end, we defined user-level requirements for the new functionality. The result of this process was the design and implementation of InterNote. One aspect of InterNote involves a fundamental extension to Intermedia's navigational linking paradigm. Instead of simply being able to traverse links, users are now also able to transfer data across the links using a technique we call warm linking. In this paper we describe extensions to our hypermedia framework to support annotative collaboration, including the user interface of the new linking functionality and the InterNote extension. Finally, we discuss our plans for future work.

Utting, Kenneth and Yankelovich, Nicole (1989): Context and Orientation in Hypermedia Networks. In ACM Transactions on Information Systems, 7 (1) pp. 58-84.

The core of hypermedia's power lies in the complex networks of links that can be created within and between documents. However, these networks frequently overwhelm the user and become a source of confusion. Within Intermedia, we have developed the Web View - a tool for viewing and navigating such networks with a minimum of user confusion and disorientation. The key factors in the Web View's success are a display that combine a record of the user's path through the network with a map of the currently available links; a scope line that summarizes the number of documents and links in the network; and a set of commands that permit the user to open documents directly from the Web View.
