The initial target application for this work is to support astronaut training operations. MonitAR will enable astronauts to operate and maintain numerous systems that might unexpectedly break or provide emergency first aid without support from Earth. By adding AR-enabled look-ahead capability in monitoring procedure performance, MonitAR will provide timely guidance to keep astronauts on task. Other potential applications for MonitAR include situations where users are under stress, required to follow procedures to accomplish certain tasks, and train to maintain proficiency in them. Examples include maintenance operations on complex systems like airplanes, ships, industrial control systems, and so on. MonitAR could also be used for providing first aid in the field when a medical doctor is not present. Potential customers include DoD's Telemedicine and Advanced Technology Research Center (TATRC), FEMA for relief/response operations, and the Center for Disease Control (CDC) for epidemic control procedures. In the private sector, companies that provide industrial control systems would find MonitAR useful in handling abnormal situations in refineries, electrical and nuclear facilities, and manufacturing settings.
