Switch and Deliver: Display Layouts for MOMV (Multiple Operator Multiple Video feed) Environments

‘Switch and Deliver’ is a research project directed to design and develop tools/techniques and procedures to aid operators in handling Multiple Operator Multiple UAV (unmanned aerial vehicles) environments. It aims to identify what information and which tools and layouts will decrease switch-costs and improve overall mission performance. Nevertheless, most tools/techniques can be generalized to any Multiple Operator Multiple Video feed (MOMV) environments, where control of multiple video sources, task switching and/or coordination with other operators are necessary for mission success. In a paper , to be presented shortly in COGSIMA 2011, we describe a study conducted on proficient operators, examining three display layouts.where we examined how the operating interface facilitates handoffs and video feed switching among operators.

Here are examples of the Layouts we have been examining:

  • In the Baseline layout (far left), contains  four equal sized windows: three windows show 3 different video feeds, and one window shows the C2 map. The payloads which were controlled by the user had an icon of a person on the top left side of the video.
  • In the Adaptive layout (center) window sizes change automatically according to user’s operations (i.e., time spent on window and performing operations in the window). Thus, in any defined time, the window that was most ‘active’ was larger than the other three windows.
  • In the User Controlled layout (right) , window sizes changes as well, except not automatically.  The user selected which window to enlarge. Thus, the large window was the one the user selected to enlarge.

Success rate, detection times, payload ‘energy’ (i.e., how much movement was done by the payload)  and Subjective evaluations and workload of the very experienced operators that participated in this study raised some interesting issues regarding fixed versus adaptive window size in MOMV environments.

  • This  study is only one of the many studies performed in the framework of this research project. The necessity and importance of tools in reducing operators’ workload and improving mission performance was again reinforced.   In  future studies, we plan to further explore the interactions that emerged.
