The Project ...

This was a semester-long project meant to introduce students to the basic practices in human computer interaction design. With an initial concept in mind, we performed interviews, observations and user testing sessions to develop an interface. The course also partnered with Nokia Research and used Nokia N93 and N95 phones as a platform to develop a mobile interface.

The Solution ...

I worked with two other students, Jim Ratcliffe (a fellow LDT student) and Wes Mateo (Class of '08 Computer Science student), to develop a program for the Nokia N95 that would allow teachers in developing countries to author and share classroom presentations. We used Python to take advantage of the mobile platform, in order to add interactive functionality to presentations. Teachers can create slides that are quiz questions, which students can text answers to in real time, thus allowing teachers to have an instantaneous feedback mechanism in their classrooms. We demonstrated the project using a low-cost Mitsubishi Pocket Projector.
