A Twitter-Based Graphing Tool
Carnegie Mellon University
Carnegie Mellon University (CMU) Human-Computer Interaction Institute Ph.D. student Ian Li (pictured) has developed Grafitter, a Twitter-based program that lets users create and see a graph of their behavior. Grafitter won the 2009 Carnegie Mellon University Smiley Award, which recognizes CMU student innovation in technology-assisted person-to-person communication. Last year, Li's Web-based Moodjam application, which tracks users' emotional states, received an honorable mention.
"I create technologies that help people collect and see information about themselves," Li says. "Grafitter is only as useful as you make it. If there is something about your life that you are curious about, start recording it and study your graphs." Li says Grafitter could be used to record a user's weight, the amount of exercise they receive, and the food they eat, by sending Twitter messages with special tags. The messages can be viewed as graphs and shared with a community of friends if desired. Grafitter is fun and easy to use, says CMU professor Scott Fahlman.
