A robot that acts out your dreams

I spent a night at The Albany Regional Sleep Disorder Center in Albany, NY. There they wired me up with a variety of sensors, recording everything from EEG to EKG to eye positioning data. We then took that data and interpreted it in two ways:

The eye position data we simply apply to the position the robot's heads is looking. So if my eye was looking left, the robot looks left.

The use of the EEG data is a bit more complex. Running it through a machine learning algorithm, we identified several patterns from a sample of the data set (both REM and non-REM events). We then associated preprogrammed robot behaviors to these patterns. Using the patterns like filters, we process the entire data set, letting the robot act out each behavior as each pattern surfaces in the signal. Periods of high activity (REM) where associated with dynamic behaviors (flying, scared, etc.) and low activity with more subtle ones (gesturing, looking around, etc.). The "behaviors" the robot demonstrates are some of the actions I might do (along with everyone else) in a dream.
