Here is the abstract of one of my latest studies. It appears in a special issue of JCEDM “Improving Human-Robot Interaction in Complex Operational Environments: Translating Theory into Practice”

This study investigated scalability of unmanned vehicle displays for dismounted warfighters. Task performance, workload and preferences for three display devices were examined in two operational settings: tele-operation of an unmanned ground vehicle and intelligence gathering from a remote unmanned vehicle. Previous research has demonstrated variability in operational needs with regard to active tele-operation versus passive intelligence gathering. Thus, it was important to identify whether there was actually a dichotomy between the two in terms of screen space requirements and whether this difference stems from task differences or other factors. Thirty-one soldiers participated in a field study at Ft. Benning, GA. They were required to perform tele-operation and intelligence gathering tasks. Results reconfirmed our hypothesis that display type influences performance in intelligence-related tasks that require the use of video feed and digital map. No significant differences among display types were found in the UGV tele-operation task. In conclusion, dismounted warfighters can adequately perform both active and passive duties with a hand held device where the video window is as small as 4.3 inches in diameter. However, monocular HMDs for robotic displays can be problematic and should be carefully assessed before use in dismounted warfighters missions.
