I am currently testing various ThinkGear addons for OpenFrameworks. A desirable one is the ofxThinkGear from Ampontang. The ThinkGear bundle functions as a programming interface to simplify coding and at the same time bypass the 0.5 second sampling restriction of the ThinkGear connector.
There is another addon ofxThinkgear from Laurent Bedubourg that uses the primitive serial interface to retrieve the data from the Neurosky mindset. Nevertheless, it cannot obtain the eye blink event from this interface.
