The ESP: Emotional Social Intelligence Prosthetic enables a speaker to detect boredom in a listener via a vibrating belt. While not a true mind-reading device since it only infers affective-cognitive mental states via facial signals, it clearly shows that MIT is working on invading people's minds to learn their secrets. From the ESP mission statement:
In psychology, theory of mind or "mind-reading" describes our ability to attribute mental states to others from their behavior and to use that knowledge to guide our actions and predict those of others.
Of course, this touchy-feely device is only being released to condition public acceptance of wearable mind-reading doodads. Presumably their more invasive psychotronics-based MR technology -- technology that would, coincidentally, be rendered useless with wide-spread adoption of deflector beanies -- is only being shared with their partners in the Military-Industrial Complex (the ESP project is funded by the National Science Foundation, a government agency in league with DARPA).
Of note: the founder of Media Lab, Nicholas Negroponte, is the brother of John Negroponte, Director of National Intelligence, who oversees all US intelligence agencies including the CIA, FBI, NSA, NGA, NRO, and others interested in either reading or altering your mind.
Nicholas' current project with Media Labs is a universal mind-control delivery platform targeted at the Third World. I am working on getting one of these devices from undercover paranoid agents to see if MindGuard can be made to run on it. Hopefully the underprivileged children of the world won't have to fall victim to the nefarious schemes of the Negroponte brothers.
