Gadget Tracks Brainwaves As You Watch TV

Taking a cue from A Clockwork Orange, San Francisco neuromarketing firm EmSense has launched what it says is "the first ever scalable, non-invasive psychological and brainwave measurement technology — made specifically for market research." The EmBand measures your brain activity, your emotional responses, and your level of engagement in what you are watching on TV. The collected data is then sold to marketers who can come up with more interesting ads to be skipped over with your DVR.
