Musical Table Teaches Basics of Computer Programming
Coasters can be moved along TuneTable's projection surface to make music using elements of computer programming
Museums are the next places K-12 students will have a chance to learn about computer programming. As part of a $3 million grant from the National Science Foundation, researchers at the Georgia Institute of Technology and Northwestern University have built a musical, interactive tabletop exhibit that teaches the basics of computer coding.
It’s called TuneTable. Students move coasters along the table’s projection surface to make a musical piece using elements of computer programming. Then they tap the surface to play a series of beats, beeps and samples. The table will be installed at the Museum of Design Atlanta in early 2017 and Chicago’s Museum of Science and Industry in the summer.
The project addresses a national need to make major strides in computer programming literacy for K-12 students.
“It’s also about changing the attitude about computation and exposing it to people that might not have sought it out otherwise,” said project lead Brian Magerko, an associate professor in Georgia Tech’s Ivan Allen College of Liberal Arts. “Hopefully some of them will think it is a cool, new way to express themselves.”
The table includes basic computing programming elements that people would use when learning programming formally for the first time, such as iteration and go-to statements.
TuneTable’s interactive surface uses computer vision to detect printed markers — officially they’re called fiducials — on the coasters. Each coaster is assigned a sound or programming command, such as a splitter or repeater. People link them together to form a chain of electronic and hip hop sounds.
“Manipulating notes, chords and rests requires a lot of music theory knowledge,” said Magerko, who also leads Georgia Tech’s Adaptive Digital Media lab. “Instead, we’re opting to manipulate music samples with code. And certain genres, such as electronic and hip hop, map very well computationally.”
“The table allows us bring the basics of computer programming out of the classroom and into more informal settings such as museums,” said Freeman, a co-principal investigator on the NSF grant. “Kids can be playful and social, just by walking up and giving it a try.”
Once the exhibit arrives in museums, people will be able to create their own music and email it to themselves. They can continue tinkering with the code when they get home using EarSketch or a tablet version of the software, which is being designed by Northwestern’s Mike Horn.
