Burke, Moira, Amento, Brian and Isenhour, Philip (2006): Error correction of voicemail transcripts in SCANMail. In: Proceedings of ACM CHI 2006 Conference on Human Factors in Computing Systems 2006. pp. 339-348.
Despite its widespread use, voicemail presents numerous usability challenges: People must listen to messages in their entirety, they cannot search by keywords, and audio files do not naturally support visual skimming. SCANMail overcomes these flaws by automatically generating text transcripts of voicemail messages and presenting them in an email-like interface. Transcripts facilitate quick browsing and permanent archive. However, errors from the automatic speech recognition (ASR) hinder the usefulness of the transcripts. The work presented here specifically addresses these problems by evaluating user-initiated error correction of transcripts. User studies of two editor interfaces-a grammar-assisted menu and simple replacement by typing-reveal reduced audio playback times and an emphasis on editing important words with the menu, suggesting its value in mobile environments where limited input capabilities are the norm and user privacy is essential. The study also adds to the scarce body of work on ASR confidence shading, suggesting that shading may be more helpful than previously reported.

Ganoe, Craig, Somervell, Jacob P., Neale, Dennis C., Isenhour, Philip, Carroll, John M., Rosson, Mary Beth and McCrickard, D. Scott (2003): Classroom BRIDGE: using collaborative public and desktop timelines to support activity awareness. In: Proceedings of the 16th annural ACM Symposium on User Interface Software and Technology November, 2-5, 2003, Vancouver, Canada. pp. 21-30.
Classroom BRIDGE supports activity awareness by facilitating planning and
goal revision in collaborative, project-based middle school science. It
integrates large-screen and desktop views of project times to support
incidental creation of awareness information through routine document
transactions, integrated presentation of awareness information as part of
workspace views, and public access to subgroup activity. It demonstrates and
develops an object replication approach to integrating synchronous and
asynchronous distributed work for a platform incorporating both desktop and
large-screen devices. This paper describes an implementation of these concepts
with preliminary evaluation data, using timeline-based user interfaces.

People working collaboratively must establish and maintain awareness of one
another's intentions, actions and results. Notification systems typically
support awareness of the presence, tasks and actions of collaborators, but they
do not adequately support awareness of persistent and complex activities. We
analysed awareness breakdowns in use of our Virtual School system -- stemming
from problems related to the collaborative situation, group, task and tool
support -- to motivate the concept of activity awareness. Activity awareness
builds on prior conceptions of social and action awareness, but emphasizes the
importance of activity context factors like planning and coordination. This
work suggests design strategies for notification systems to better support

MOOsburg is a community-oriented multi-user domain. It was created to enrich the Blacksburg Electronic Village (BEV) by providing real-time, situated interaction and a place-based model for community information. Three versions of MOOsburg have been developed: a classic text-based MOO, a MOO extended to drive a Web-browser, and a Java-based system. The most recent version of MOOsburg is fundamentally different from classic MOOs, supporting distributed system development and management and a direct manipulation approach to navigation. We are currently developing a variety of community-oriented applications, including a virtual science fair and a dispersed natural history museum.

Isenhour, Philip, Rosson, Mary Beth and Carroll, John M. (2001): Supporting Interactive Collaboration on the Web with CORK. In Interacting with Computers, 13 (6) pp. 655-676.
The World Wide Web has served as a medium for collaboration since its inception. Web-based collaboration has, however, been dominated by systems supporting asynchronous activities such as sharing documents and participating in discussion forums. Supporting interactive, synchronous collaboration on the Web has proven much more challenging. In this paper we describe three of the challenges encountered in the context of supporting network-based collaboration among middle and high school science students: integrating synchronous and asynchronous modes of interaction, minimizing consumption of bandwidth, and adapting non-collaborative software components for collaborative use. We then present the Content Object Replication Kit, a toolkit for building interactive Java-based collaborative systems for use on the Web.
