This paper presents a method to represent two-person interactions at a semantic level with a natural language description. A human interaction is composed of two singleperson actions, which in turn are made up of torso and arm/leg motions. We adopt the 'verb argument structure' in linguistics to represent human action in terms of triplets. Various two-person interactions are represented at a detailed level using multiple triplets aligned along a time line according to the spatial/temporal
