In safety- and security-critical applications like video surveillance it is crucial that human operators detect task-relevant events in the continuous video streams and select them for report or dissemination to other authorities. Usually, the selection operation is performed using a manual input device like a mouse or a joystick. Due to the visually rich and dynamic input, the required high attention, the long working time, and the challenging manual selection of moving objects, it occurs that relevant events are missed. To alleviate this problem we propose adding another event selection process, using eye-brain input. Our approach is based on eye tracking and EEG, providing spatio-temporal event selection without any manual intervention. We report ongoing research, building on prior work where we showed the general feasibility of the approach. In this contribution, we extend our work testing the feasibility of the approach using more advanced and less artificial experimental paradigms simulating frequently occurring, basic types of real surveillance tasks. The paradigms are much closer to a real surveillance task in terms of the used visual stimuli, the more subtle cues for event indication, and the required viewing behavior. As a methodology we perform an experiment (N=10) with non-experts. The results confirm the feasibility of the approach for event selection in the advanced tasks. We achieve spatio-temporal event selection accuracy scores of up to 77% and 60% for different stages of event indication.
