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.

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.
