In ongoing work on spatial relations and scene interpretation, we present a system that linguistically describes the motion of an object in a temporal sequence. This description, called the dynamic linguistic description, is inferred from a sequence of static linguistic descriptions explaining the relative position, at different instances, between a moving object and a stationary object. In this preliminary work, the moving object is assumed to be moving in a straight path at a constant velocity. The scene is monitored from a fixed pose with a constant frame rate. The proposed system is potentially useful as a low-bandwidth remote observation system capable of linguistically reporting relative position and motion in a scene.
