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.
