Loren Terveen

Professor of Computer Science and Engineering

Loren Terveen is a professor of computer science at the University of Minnesota. Before joining the University of Minnesota, he received his PhD in Computer Sciences from the University of Texas at Austin, and then spent 11 years at AT&T Labs / Bell Labs. Terveen is an expert in the areas of human-computer interaction and social computing. He has published more than 90 scientific papers, holds nine patents, has consulted on intellectual property cases and advised several startup companies, and has been invited to give talks at a number of leading research institutions. He has held many leadership positions in his professional community, including co-chairing the CHI 2002 Conference and the IUI 1998 Conference, serving as program chair for CSCW 2004 and CSCW 2013, chairing the CSCW Steering Committee, and serving on the SIGCHI Executive Committee. Within his department, he has served as director of graduate studies and chair of the faculty search committee. He is a Distinguished Scientist of the Association for Computing Machinery

Research Description

Terveen currently is involved in a number of projects analyzing social media data and designing and evaluating social computing systems. His two major projects are Cyclopath and CitizenSense.

Cyclopath is an interactive bicycle routing site and geographic wiki. Users can get personalized bike-friendly routes. They can edit the transportation map itself, monitor the changes of others, and revert them if necessary. Discussion forums let users geolink topics to objects on the map. Cyclopath has been available to Twin Cities cyclists since August 2008 and has more than 2500 registered users. Users have entered over 85,000 ratings and made more than 12,000 edits to the map. Each day during riding season, several dozen registered users and a hundred or more anonymous users visit the site and request more than 150 routes. Terveen's group is in the process of extending Cyclopath to cover the entire state of Minnesota. In addition, they've created a set of extensions to Cyclopath called “Cycloplan” that let transportation planners share planned routes with the public and get public feedback, and let users request officially approved routes if they choose. Terveen and his students have published about a dozen papers on Cyclopath, covering topics such as the system design and rationale, the routing algorithm, and various analyses of user behavior.

CitizenSense is a software infrastructure for creating and managing participatory sensing campaigns. We are particularly motivated by the needs of local government and non-profit agencies to gather data. Representative campaigns include:

  • Gathering data on the use of public transit to inform transit planners' decisions concerning issues like whether and where new bus stations and bus routes are needed
  • Monitoring the health of trees on public land, so that foresters can cut down diseased trees
  • Counting bicycle and pedestrian traffic to enable cities to add new paths and trails where they are most needed

A prototype version of CitizenSense has been implemented, and collaborations are underway to deploy several campaigns.
