A group of engineers are finding a way to help universities with large classes be a little more like, well, Union College.
A lecture hall with hundreds of students provides little opportunity for interaction between professor and student. That got five Union engineers thinking about how they might help others get the kind of small-class interaction that they enjoy.
They have adapted a wireless network technology known as Bluetooth to enable students to use their notebook computers or personal digital assistants (PDAs) to ask questions of a lecturer or teaching assistant. The network also would allow the presenter or assistant to answer questions or survey the audience.
Matt Abrams '01, computer systems engineering; Nelson Abramson 02, electrical engineering; Mahir Aydin '01, CSE; Eric Giang '03, EE; and Andrew Stone '02 CSE are to present their project – “Bluetooth-Enabled Wireless Presentation System” – in a poster session at the 11th annual Steinmetz Symposium on Saturday from 1:30 to 3 p.m. in the Nott Memorial. Their advisors are David Hemmendinger, John Spinelli and Cherrice Traver.
A tiny Bluetooth chip, soon to be available in a many personal computing devices, transmits a radio signal that can be received by another Bluetooth chip within 10 meters. A room full of Bluetooth chips provides a low-cost solution, with no network setup, anywhere a presentation is given.
The group developed the project over two terms as part of the IEEE Computer Society International Design Competition. Seventy-five teams from institutions around the world submitted proposals employing the Bluetooth chip. Later this month, IEEE will invite the top 10 to present their projects at the finals in Washington.
The hardest part of the project, say the students, was figuring out the best use for the technology. “The technology is so new and applicable to so many different problems, it was difficult choosing one specific application that is original, interesting, and something that we could accomplish in the given time frame,” says Abrams.
“Anytime you have a large room filled with students, people are reluctant to ask questions,” says Abrams. And, says Spinelli, students who wait until after class to ask a question may ask it anonymously during class.
