We proposed the notion of Reality-Based Interaction (RBI) as a unifying concept to tie together a large subset of emerging interaction styles. Interfaces should adhere to reality-based principles unless designers explicitly choose to make a tradeoff where they sacrifice reality in order to gain other positive qualities. When a reality-based interface has been designed, and the reality tradeoffs ... read morehave been carefully considered, it is very difficult to determine whether or not the reality-based principles or reality tradeoffs resulted in a 'good' interface. To address this problem, we use functional near infrared spectroscopy (fNIRs), a new, non invasive brain imaging technique, to complement standard usability experiments. We demonstrate an experimental protocol and data analysis algorithms which can help evaluators of RBI systems to acquire objective, real time metrics of users' workload, and other states while working with a given interface.read less
