This paper considers the problem of recognizing spontaneoushuman activities from a robot's perspective. We present a novel dataset,where data is collected by an autonomous mobile robot moving aroundin a building and recording the activities of people in the surroundings.Activities are not specified beforehand and humans are not prompted toperform them in any way. Instead, labels are determined on the basisof the recorded spontaneous activities. The classification of such activi-ties presents a number of challenges, as the robot's movement affects itsperceptions. To address it, we propose a combined descriptor that, alongwith visual features, integrates information related to the robot’s actions.We show experimentally that such information is important for classify-ing natural activities with high accuracy. Along with initial results forfuture benchmarking, we also provide an analysis of the usefulness andimportance of the various features for the activity recognition task.
