Recognizing User's Context from Wearable Sensors

Brian Clarkson, Kenji Mase, and Alex Pentland
March, 2000

We describe experiments in recognizing a personís situation from only a wearable camera and microphone. The types of situations considered in these experiments are coarse locations (such as at work, in a subway or in a grocery store) and coarse events (such as in a conversation or walking down a busy street) that would require only global, non-attentional features to distinguish them.
