In expert video analysis, the selection of certain events in a continuous video stream is a frequently occurring operation, e.g., in surveillance applications. Due to the dynamic and rich visual input, the constantly high attention and the required hand-eye coordination for mouse interaction, this is a very demanding and exhausting task. Hence, relevant(More)
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(More)
In this paper, we show how recordings of gaze movements (via eye tracking) and brain activity (via electroencephalography) can be combined to provide an interface for implicit selection in a graphical user interface. This implicit selection works completely without manual intervention by the user. In our approach, we formulate implicit selection as a(More)
Moving target acquisition is a challenging and manually stressful task if performed using an all-manual, pointer-based interaction technique like mouse interaction, especially if targets are small, move fast, and are visible on screen only for a limited time. The MAGIC pointing interaction approach combines the precision of manual, pointer-based interaction(More)
Coping with threats such as terrorism, crime, natural hazards or industrial accidents requires early detection and correct assessment of critical situations, followed by appropriate actions to avoid potential damage to person or property. We here focus on threat prevention in closed properties of traffic infrastructures (railway stations, harbours ,(More)
