# Key Points from IRC Log

• Utopiah wondered if anyone was using real-time face recognition patterns with webcam and OpenCV to rate browsing sessions based on facial expressions, suggesting an interest in emotion-tracking technology for web browsing.

• kanzure shared links to open-source projects including ISO 15926 equipment inventory management (http://sourceforge.net/projects/cat15926/) and open-source transcranial magnetic stimulation projects (http://open-rtms.sf.net/ and http://transcenmentalism.org/OpenStim/).

• qDot_ discussed the Emotiv EPOC headset and the "Emokit" project that decrypted its signals, noting they had added a new encryption key and got the drivers working on OS X, raising questions about whether encryption is per unit type or per individual device.

• A discussion about consumer EEG devices compared Emotiv EPOC with Neurosky, with qDot_ noting that while Neurosky has fewer sensors and is "flakey," they treat developers better than Emotiv, which encrypts raw signals and charges more for research editions.

• augur inquired about research into using ambient microwaves as a power source for small devices, with JayDugger mentioning anecdotal examples of this being done with AM radio receivers.
