The plain old television in a smart apartment

Our GO (www.go-outside.org) project focuses on community access for the cognitively impaired population. In addition to devising new facilities, we are interested in using existing appliances found in an apartment to interact with a user to help with a specific task, e.g., making a trip to the doctor. This requires establishment of collaboration protocols between the appliances (and smart agents) and user to be established. These protocols must enforce certain safety properties, e.g., that the user get timely information to start a task. We will show how we use a light-weight formal modeling toolkit to reason about a protocol's ability to meet safety properties
