    Assisting Mouse Pointer Recovery in Multi-Display Environments
    (Mensch und Computer 2015 – Proceedings, 2015) Fortmann, Florian; Nowak, Dennis; Bruns, Kristian; Milster, Mark; Boll, Susanne
    Recovering the mouse pointer in a multi-display environment after it got lost, e.g., because the user shifted his or her visual attention to another task, can be very annoying and frustrating. The reason is that the user has to oversee a large display space requiring sequential sampling actions. These actions consume psycho-physiological effort for moving the eyes and head around, and increase the time needed to recover the mouse pointer. In this paper, we present an assistant system to support users to recover their mouse pointers in multi-display environments. A preliminary user study showed no significant improvement of mouse pointer recovery time, but usability and satisfaction were assessed positive. This work was carried out as part of a course on human-machine interaction at the University of Oldenburg.

    SA-Based Guidance to Aid UAV Swarm Supervisory Control: What do Experts Say?
    (Mensch & Computer 2013: Interaktive Vielfalt, 2013) Fortmann, Florian
    Accident reports reveal that incorrect Situation Awareness (SA) is often the cause of human errors in context of supervisory control of Unmanned Aerial Vehicles (UAV). Many of these errors can be attributed to inadequate scanning behaviour. In the future, the number of UAVs human operators have to supervise at the same time will increase. Thus, methods are needed, which could aid deficits in the scanning behaviour and SA. Our work focuses on the development of an assistance system for UAV swarm supervisory control, which optimizes the scanning behaviour of a human operator based on the analysis of actual SA needs. In this paper, we present the design of the assistance system and results of an early prototype evaluation performed with three experts from the perspectives usability, human factors and UAV manufacturing to get an impression of the expectable user acceptance, safety impact and market potential.
