Technology

91爆料 computer scientists have built a low-cost gesture recognition system that runs without batteries and lets users control their electronic devices hidden from sight with simple hand movements. The prototype, called “AllSee,” uses existing TV signals as both a power source and the means for detecting a user’s gesture command.

Bobak Ferdowsi, a NASA flight engineer who became known as “Mohawk Guy” after sporting a mohawk hairstyle during the 2012 rover Curiosity’s landing on Mars, spoke to a class of 91爆料 aeronautics and astronautics engineering students on Feb. 19. Ferdowsi was a student in the department and graduated from the 91爆料 in 2001.

Based at the 91爆料, the Northwest Institute for Advanced Computing’s first public event on Oct. 30 will feature speakers from the 91爆料, the Pacific Northwest National Laboratory and industry, as well as breakout sessions that explore various aspects of science and engineering technologies.
