Novel patterns of visual-vestibular intersensory stimulation often result in symptoms simulator sickness, raising health and safety concerns regarding virtual environment exposure. Two experiments investigated the effect conflicting cues on subjective reports sickness during after a 30-min exposure to head-coupled interface. Virtual image scale factors (0.5, 1.0, 2.0 magnification, generated by varying geometric field view angle) were Experiment 1, additional system time delays (125, 250 ms)...

Remotely operated vehicles (ROVs) are vehicular robotic systems that teleoperated by a geographically separated user. Advances in computing technology have enabled ROV operators to manage multiple ROVs means of supervisory control techniques. The challenge incorporating telepresence any one vehicle is replaced the need keep human “in loop” activities all vehicles. An evaluation was conducted compare effects automation level and decision-aid fidelity on number simulated remotely could be...

A consortium of government, industry and academia is currently working to establish minimum operational performance standards for Detect Avoid (DAA) Control Communications (C2) systems in order enable broader integration Unmanned Aircraft Systems (UAS) into the National Airspace System (NAS). One subset these will need address DAA display requirements that support an acceptable level pilot performance. From a pilot's perspective, task maintenance self separation collision avoidance from...

Unmanned aerial vehicle (UAV) control stations feature multiple menu pages with systems accessed by keyboard presses. Use of speech-based input may enable operators to navigate through menus and select options more quickly. This experiment examined the utility conventional manual versus speech for tasks performed a UAV station simulator at two levels mission difficulty. Pilots continuous flight/navigation task while completing eight different data entry types each modality. Results showed...

The Air Force Research Laboratory's Human Effectiveness Directorate (AFRL/HE) supports research addressing human factors associated with Unmanned Aerial Vehicle (UAV) operator control stations. Recent research, in collaboration Rapid Imaging Software, Inc., has focused on determining the value of combining synthetic vision data live camera video presented a UAV station display. Information is constructed from databases (e.g., terrain, cultural features, pre-mission plan, etc.), as well...

Supervisory control of multiple unmanned aerial vehicles (UAVs) raises many questions concerning the balance system autonomy with human interaction for effective operator situation awareness and performance. The reported experiment used a UAV simulation environment to evaluate two applications levels across primary tasks: allocation (assignment sensor tasks vehicles) router (determining vehicles’ flight plans). In one application, level was same these tasks. other, differed, being more...

A method for determining the self-confidence of autonomous systems is proposed to assist operators in understanding state unmanned vehicles under control. sensing-optimization/verification-action (SOVA) model, similar perception-cognition-action human informational processing has been developed illustrate how interact with their environment and areas uncertainty affect system performance. LIDAR GPS were examined scenarios where sensed surroundings could be inaccurate, while discrete...

In complex UAV control stations, it is important to alert operators actionable information in a timely manner. Tactile displays may alleviate visual workload by transmitting through the skin, cueing high priority, unexpected events. The utility of tactile alerts (vibration on wrists) substitution for aural alerts, as redundant cue was examined. Participants responded critical events alerted with or cues, while performing multiple tasks simulated station. Results showed that there were no...

Supervisory control of multiple unmanned aerial vehicles (UAVs) raises many issues concerning the balance system autonomy with human interaction for optimal operator situation awareness and performance. A UAV simulation environment designed to manipulate application automation was used evaluate participants' performance on routing tasks under three levels automation. Trials also involved completion several mission-related secondary as participants supervised either one or UAVs. Both...

In complex systems, it is difficult to efficiently provide operators with timely and meaningful information. Tactile displays may alleviate visual workload by transmitting information through the skin. This study examined utility of active tactile alerts versus salient and/or auditory in an unmanned aerial vehicle ground control station simulation. Tactor location (right or left arm) number factors vibrating (one two) were used code three types alerts. Results showed that stimulation, when...

This paper provides a detailed description of concept demonstration that illustrates an adaptable operator-automation interface for applications involving multiple Unmanned Aerial Systems (UAS). Key hardware and software components are described, as well the changes made on previous prototype focused single UAS applications. The four control methods, ranging from manual (operator controls vehicle’s flight with stick throttle control) to high level “plays” (operator’s verbal command initiates...

Abstract Despite the continuing development of effective cognitive and behavioural interventions for Generalised Anxiety Disorder (GAD) less attention has been paid to important issue improving treatment accessibility affordability. Self-management approaches that utilise convenience Internet may provide a means by which more people can avail themselves treatments. To date, studies examining effectiveness such GAD lag behind work conducted with other clinical problems. This study describes...

Unmanned aerial systems (UAS) are starting to access manned airspace today and this trend will grow substantially as the number of UAS their associated missions expand. A key challenge safely integrating into National Airspace System (NAS) is providing a reliable means for sense avoid (SAA) other aircraft. The US Air Force addressing through Common Airborne Sense Avoid (C-ABSAA) program. C-ABSAA developing sophisticated “sense-and-avoid” capability that be integrated onboard larger UAS. This...

Tactile displays may alleviate visual workload in complex UAV control stations, cueing operators to high priority events via the haptic channel. Previous results suggest that tactile alerts (vibration on wrists) can substitute for aural alerts, as a redundant cue relatively short test sessions. The present experiment investigated whether are advantageous auditory loads during longer periods of vigilance. Participants responded alerted or cues, while performing multiple tasks simulated...

With advances in automation technologies, systems are now being considered wherein a single operator supervises multiple unmanned aerial vehicles. Supervisory control of highly autonomous will require new interface design. The present effort extends delegation concept to enable pilot flexibly change the role during course mission, seamlessly transitioning between four different modes ranging from manual (pilot controls vehicle’s flight with stick and throttle control) high level “plays”...
