“…Overall, results of the current study are consistent with automation research that operators may develop overreliance on the automatic system and this complacency may negatively affect their task performances (Parasuraman et al, 1993). Thomas and Wickens (2000) showed that, when participants had access to information gathered from automatically panning cameras, they tended to prematurely close the automatic panning feature prior to finishing examining the entire environment. Participants manually panning the cameras, on the other hand, had significantly higher target detection performance, which indicated more adequate panning.…”

In this study, we simulated a generic mounted crew station environment and conducted an experiment to examine the workload and performance of the combined position of gunner and robotics operator. Results showed that participants' gunnery task performances degraded significantly when he had to concurrently monitor, manage, or teleoperate an unmanned ground vehicle compared to the gunnery single task condition. For the robotics tasks, participants had the lowest performance when using the semi-autonomous robot, indicating overreliance on the aided target recognition capabilities available when task load was heavy (i.e., concurrent performance of the gunnery task). Participants' perceived workload increased consistently as the concurrent task conditions became more challenging. Individual difference factors such as spatial ability and perceived attentional control were found to correlate significantly with some of the performance measures. Implications for military personnel selection were discussed.The goal of this research was to examine whether gunners in a Future Combat System (FCS) vehicle such as the Mounted Combat System (MCS) were able to effectively maintain local security (i.e., perform their gunner's tasks) while managing unmanned assets. The current FCS concept for the MCS is that it will be operated MILITARY PSYCHOLOGY,

“…An improved user interface should benefit the operator's integration of information from different sources. It is worth noting, however, that integrating information from different frames of reference (e.g., exocentric and egocentric) can be challenging to the operator, and the potential human performance issues associated with such displays need to be carefully evaluated (Olmos, Wickens, & Chudy, 2000;Thomas & Wickens, 2000). In addition, operators may be susceptible to saliency effects and anchoring heuristic/bias.…”

The goal of this research was to examine the ways in which human operators interact with simulated semiautonomous unmanned ground vehicles (UGVs), semiautonomous unmanned aerial vehicles (UAVs), and teleoperated UGVs (Teleop). Robotic operators performed parallel route reconnaissance missions with each platform alone and with all three platforms. When given all three platforms, participants failed to detect more targets than when given only the UAV or UGV; they were also less likely to complete their mission in the allotted time. Target detection during missions was the poorest with the Teleop alone, likely because of the demands of remote driving. Spatial ability was found to be a good predictor of target-detection performance.

“…In addition to issues involving situation awareness, previous work has identified a number of other issues caused by a restricted field-of-view, such as cognitive tunneling-an individual failing to recognize landmarks, even those which are in view [39], errors in distance and depth judgments [47], and an impaired ability to detect targets or obstacles [3,43].…”

Robotic telepresence systems-videoconferencing systems that allow a remote user to drive around in another locationare an emerging technology for supporting geographicallydistributed teams. Thus far, many of these systems rely on affordances designed for stationary systems, such as a single, narrow-view camera to provide vision for the remote user. Teleoperation has offered some solutions to this via an augmented field-of-view, but how these solutions support task outcomes in collaborative mobile telepresence tasks has yet to be understood. To investigate this, we conducted a three condition (field-of-view: narrow (45°) vs. wide-angle (180°) vs. panoramic (360°)) between-participants controlled laboratory experiment. We asked participants (N = 24) to collaborate with a confederate via a robotic telepresence system while using one of these views in a redecoration task. Our results showed that wider views supported task efficiency and fewer collisions, but were perceived as more difficult to use.
