Notification systems attempt to deliver current, important information to the user in an efficient and effective manner. Examples of familiar notification systems include instant messaging systems, system and user status updates, email alerts, and news and stock tickers. With the popularity of these systems skyrocketing in recent years, our group explores the effects of incoming notifications on ongoing computing tasks, creating models for their design, implementation, and evaluation. Please feel free to contact us with questions or comments about our work.
Selected Designs
seeVT
Leverages location-based technology for on-the-go handheld and Tablet users, providing appropriate notification of nearby events of interest.
See also: Mobile Spatial Interaction workshop paper, Sampat thesis
Online Enlightenment
Leverages instant messenger data in an off-the-desktop semi-public display showing online presence data and history.
See also: CSCW 2006 note
ClassroomBRIDGE
Notifies middle- and high-school teachers of progress on cross-classroom group science projects using large displays of aggregate project data in the classroom.
See also: UIST '03 overview paper, SEKE '04 design case study
Methods and Toolkits
LINK-UP
Provides a web-based development environment for notification systems; targeted for use in classrooms for educating students about HCI, by interface designers developing notification systems, and across disciplines by a variety of researchers.
See also: CADUI '03 paper on the design vision, E-Learn '04 paper on its potential use in education
Claims Library
Captures knowledge about notification systems in designer-digestible packets called claims, that can then be searched, augmented, and otherwise used by tools like LINK-UP.
See also: IRI '03 paper on the original vision, HICSS '05 paper detailing usage case studies, HCII '05 paper on envisioned future directions
Real World Interfaces toolkit
Supports the creation of off-the-desktop displays with any pluggable electronic device using X10 technology.

Lab News

January 2008 kicks off our NSF-sponsored partnership with Meridium, targeted at integrating our "Agile usability" methodology into the Meridium product development plans--toward an Agile usability tool for use by Meridium and its clients. Lab member Jason Lee is taking the lead on the project, splitting his time between Virginia Tech and Meridium.

Summer 2008 will mark the third year of the Center for HCI's NSF-sponsored Research Experience for Undergrads program led by Scott McCrickard and Woodrow Winchester. Prior years we have hosted students from North Carolina A&T, Norfolk State, Hollins, Jackson State, and UPRM, and also from Georgia Tech, Wellesley College, Oberlin, TCNJ, and (of course) Virginia Tech. Visit the REU website for more details.

Ph.D. student Shahtab Wahid presented a full paper at CHI titled "Task and Social Visualization in Software Development: Evaluation of a Prototype" co-authored with Jason Ellis, Catalina Danis, and Wendy Kellogg. The paper was nominated for best paper. (See the lab publications page for access to this and other papers from lab members.) Seven members of the lab attended CHI, and around twenty members and alums of VT and the Center for HCI were in attendance.

Lab alum Christa Chewar was appointed Academy Professor at West Point, acknowledging her extensive contributions to the educational and military missions of West Point and the Army. Visit the lab alumni page to catch up with other alumni activities.
