there and could be used, then why not use it?  Theoretically, the
Cyberlink could be operated by brain activity alone, but if I remember the
location of the electrodes right (forehead, I think?) then there is not a
lot of opertunities for picking up the type of EEG signals typically used
for BCIs.  I suppose it is possible that your subject may have some
residual EMG in the forehead that could be used, or that the remaining eye
movements could be useful with the Cyberlink.  But, unless Cyberlink
provides a lot of support, I think the Wadsworth group in Albany might be
your best option. They are doing in-home testing of BCIs now, so they
could potentially provide your patient with a system for every-day use.

I had a clients who had very little facial movement- couldn't operate a
P-Switch.  Had no success using the Cyberlink- tried for several months (and
she was a lifelong practitioner of meditation, so theoretically, she should
have been a good candidate.) It led me to think that the Cyberlink was
activated by muscle movements.

Subject: [Assistive Technology] Cyberlink Brainfingers

Has anyone has success using the Cyberlink device with the brain way
detection?  (Not eye blinks or eyebrow movements.)  I am working with a
patient who has very slow side to side eye movement only - no other
movements.  So she would be using the brain wave detection, not EMG.

Any other leads would be appreciated.

(We are going to look into the BCI research being done out of Albany as
well.)

Thanks in advance,
