This document discusses activity theory and context-based design. It notes that activity theory focuses on the unity of consciousness, actions, and activities. It also references Vygotsky's concept of mediational means and Engestrom's analysis of instruments within a subject-object-community framework. An example is given of a grandmother visiting her grandchild's home to illustrate these concepts.
