Measuring Viewer Response with Wristbands

Elliott Hedman of the MIT Media Lab is demonstrating a cute wristband with built-in sensors for measuring viewer response to entertainment. The sensor detects changes in skin properties. The data is wirelessly fed to software he has developed on a one-laptop-per-child computer (unit in background of photo). He can measure attributes related to the levels of viewer involvement.

Note: The wire under the wristband goes into the laptop, not the wristband

This technology would be good for measurements on children, since it is very non-threatening. It could also be used on adults.
