An ontology of human walk for autonomous systems

Increasing the intelligence level of path planning for autonomous systems and for their interaction with human walkers requires higher level representations for the humans displacement and the design of the corresponding ontologies. The paper proposes a sketch of an ontology of human movements for use by robots in assessing the displacement of humans in its environment and for correspondingly planning the path. The main purpose of the paper is to contribute to knowledge representation for a specific, narrow task in robotics, namely the formal representation of the knowledge about human walk, as needed for the safe and convenient displacement of autonomous systems in crowded spaces.
