Paper describes the concept and implementation of automated models of everyday activities (AM-EvAs), a novel technical tool for the perception, interpretation, and analysis of everyday manipulation tasks and activities of daily life. AM-EvAs are defined as detailed, comprehensive models describing human actions at various levels of abstraction from raw poses and trajectories to motions, actions, and activities. They integrate several kinds of action models in a common, knowledge based framework to combine observations of human activities with a priori knowledge about actions. AM-EvAs enable robots and technical systems to analyze actions in the complete situation and activity context. They make the classification and assessment of actions and situations objective and can justify their probabilistic interpretation with respect to the activities from which the concepts have been learned. In the context of assistive technology, AM-EvAs could be specifically adapted in order to enable a system to infer whether the sequence of actions it observed is typical with respect to the activity being carried out, or whether the patient observed has missed steps that were expected. Example results of AM-EvA implementations in scenarios involving setting a table are presented.
