Monitoring Attention Using Ambient FM Radio Signals

The authors investigate the classification of FM radio signal fluctuation for monitoring the attention of individuals moving toward a static object. In particular, they distinguish between an empty and populated corridor and, for the latter, determine whether the individuals are moving or standing still and whether they're directing their attention toward a particular poster. This information can provide some hint whether a person is paying attention to a specific poster as well as the location of the particular poster. This article is part of a special issue on managing attention.
