Behavior-based authentication methods are actively being developed for XR. In particular, gaze-based methods promise continuous authentication of remote users. However, gaze behavior depends on the task being performed. Identification rate is typically highest when comparing data from the same task. In this study, we compared authentication performance using VR gaze data during random dot viewing, 360-degree image viewing, and a nuclear training simulation. We found that within-task authentication performed best for image viewing (72%). The implication for practitioners is to integrate image viewing into a VR workflow to collect gaze data that is viable for authentication. 

Nuclear reactor safety is unique in that even after an incident is identified and the reactor shut down, the possibility of damage to people and environment does not stop: there is a long tail to the incident due to decay heat and potential for radiation leakage, which must also be contained properly, as exemplified in Fukushima where most radiation releases happened after initial earthquake and plant shut-down. Nuclear reactors generate close to 20% of the energy required by our nation. There is increasing interest in nuclear power as a low emissions alternative to fossil fuel-based power. Investments in the next generation of nuclear power plants include many nuclear startups such as NuScale and high-profile investments by Bill Gates’ Terra Power. Nuclear reactor operators are critical personnel who operate nuclear reactors, monitor the health of the operation, and are the first line of defense in case of an incident. Though the Nuclear Regulatory Commission creates and maintains standards and procedures for nuclear safety, their programmatic mandate involves are focused on existing technology, in the form of commercial nuclear power plants and other uses of nuclear materials through licensing, inspection and enforcement activities. This report summarizes the collected thoughts and insights from a diverse working group on the intersection of next generation technology with the training of future nuclear reactor operators.
