Situation modeling layer
CHIL Services require observation of human activity. Observation of humans and their activities is provided by perceptual components. For most human activities, there are a potentially infinite number of entities that could be detected and an infinite number of possible relations for any set of entities. The appropriate entities and relations must be determined with respect to a task or service to be provided. This is the role of the situation model. Situation models allow focusing attention and computing resources to determine the information required for operation of CHIL services. In this chapter, we introduce concepts and abstractions of situation modeling schema used in the CHIL architecture.
