    Interpretation of pointing gestures

    Oliver Herbort

    When we want to direct the attention of another person to a specific location or object, we often use pointing gestures. Pointing gestures are ubiquitously in the communication between humans and get increasingly relevant in human-computer and human-robot interaction. They facilitate interactions by complementing or replacing speech when it is difficult to indicate objects verbally (e.g. pointing at a specific star in the night sky). To understand such pointing gestures, an observer has to determine – among other things – which spatial location a pointer wants to indicate. Interestingly, how people extract the pointed-at position from another person’s pointing gesture is not well understood. With the proposed project, we systematically examine how important variables affect the spatial interpretation of pointing gestures in a highly controlled virtual reality environment. We expect that this enables to predict accurately how a given pointing gestures will be interpreted by a specific observer and which pointing gestures is best suited to single out a specific object or location. The results may be applied to improve embodied interaction in real-life, virtual or robotic systems, and provide a testbed for basic mechanisms of human perception. This research is partly supported by the German Research Council (DFG).
