REU Summer Intern: Summer intern Gary Wong (REU via CENSSIS) and MS student Zheng Zhou worked through July 2011 to convert the voice-controlled wheelchair of Capstone-April-2011 to a brain-controlled wheelchair. The chair receives one of four commands (turn lef or right, go forward, and stop) every second from the brain interface. Each checkerboard on the screen correspond to one command and the operator conveys intent by looking at the checkerboard for the desired command. The checkerboards follow unique 31-bit long m-sequence flickering patterns.

RSVP Keyboard: Our NIH-funded P300-based brain computer interface for typing was featured at local Oregon news following a paper presentation at a computational linguistics conference in Portland, where we also presented a live demo with one of our locked-in user consultants. The direct and regular input from the users help us improve the system design to fi their needs better early in the development process.

Capstone Projects: At the beginning of this academic year, I gave project ideas to three capstone teams. These teams designed (1) a voice controlled wheelchair which received the 1st place in the 2011 ECE Department Capstone Project Competition, (2) a gaze-controlled mobile robotic manipulator that received the 2nd place, and a brain-controlled flight simulator that received the 3rd place. The flight simulator project built on the concept and experience of the brain controlled iCreate project from the previous year.

April 2010
Capstone Project: I advised and closely worked with a group of capstone students on their brain controlled iCreate platform. The project won the first place in the 2010 ECE Department Capstone Project Competition. The team designed everything from data acquisition driver for the amplifier to signal processing and classification algorithms. They attended at NCUR 2010 with support from NSF. The brain interface is based on the SSVEP signal from the visual cortex. Please see the publications page for relevant papers.
