In the summer of 2014, I visisted the Microsoft Research lab in Bangalore to work with Bill Thies and Ed Cutrell of the Technology for Emerging Markets research group. With them, I designed and evaluated a few new methods for deterring dishonest behavior (cheating, lying, etc.) in online contexts. We were particularly interested in discouraging students from cheating on online quizes and exams, but we looked at Mechanical Turk and other online settings as well.
The project involved a mix of techniques from the fields of human-computer interaction and computer security. While I was there, I learned a lot about how to design user studies and how to make sense of the data that such studies produce.
Our TOCHI paper has more details on the project.
