<div> <font size="2"><font face="Arial, Helvetica, sans-serif">Hi Reinhard, suspend your disbelief , it really does what it says on the tin. It reads both facial and eye movement signals from the forehaed, but decodes brainwave activity from its eeg sensors.<br>
These signals are then FFT decoded and used to train a nueral net. The end result is that a specific thought pattern is detected and converted into a PC event.<br>

<pre style="font-size: 9pt;"><tt>hi alex,<br>
<br>
i do not believe that this device really read thought patterns. all<br>
the consumer devices i know read only the electric activity of the<br>
skull muscles.<br>
<br>
try the following: take a video of your face during using the device<br>
and take a close look at your face musculature. i'm sure (99,9%+) that<br>
you unconsciously move your face by trying to move the robot arm. the<br>
electric activity of this moving is very much higher than the activity<br>
of your brain (through the skull). the device read this activity and<br>
not the activity of your brain.<br>
<br>
best regards<br>
<br>
