DAZE: a real-time situation awareness measurement tool for driving

A driver's situation awareness (SA) while on the road is a critical factor in his or her ability to make decisions to avoid hazards, plan routes and maintain safe travel. Understanding SA can therefore be a great help when designing or evaluating new interfaces intended to support these decisions. However, existing tools for measuring SA in simulated environments require halting the simulation currently in-progress to question participants or administering post-drive questionnaires. Through our experience developing interfaces for autonomous vehicles in both simulated and on-road environments, we have found a need for real-time SA measurement designed specifically for both simulation and on-road driving scenarios. We are developing a tool, inspired by the Waze [tm] driving app, to measure SA through real time on-road event questions. The system has been tested in lab and will be further evaluated against current SA measurement tools.
