“…Perceived communicative effectiveness was measured using the modified version of the Gesture Perception Scale [40] previously employed by Williams et al [57,58], which was delivered along with the NASA TLX Survey at the end of each experiment block.…”

“…Finally, as described above, in our own work, we have investigated the use of AR augmentations as an active rather than passive communication strategy, generated as gestures accompanying natural language communication [18,57,58].…”

“…Our second independent variable, communication style, was manipulated through our secondary task. Following Williams et al [57] and Williams et al [58], we manipulated communication style by having the robot exhibit one of three behaviors:…”

“…Following Williams et al [57] and Williams et al [58], we did not examine the use of simple language without AR, as that communication style does not always allow complete referent disambiguation, resulting in the user needing to ask for clarification or guess at random between ambiguous options.…”

“…Williams et al [63] divides these new forms of non-egocentric visual gestures into allocentric visualizations that can be displayed in teammates' augmented reality head-mounted displays, and perspective-free visualizations that can be projected onto the ground. Recent work in this space has focused on allocentric gestures such as circles and arrows drawn over target objects [57,58], as well as ego-sensitive allocentric gestures such as virtual arms [17,18]. Williams et al [58], for example [see also 57], demonstrate that (non-ego-sensitive) allocentric virtual gestures, at least when tested in a simulated video-based experiment, have the potential to increase communication accuracy and efficiency, and, when paired with complex referring expressions, are viewed as more effective and likable than purely linguistic communication.…”

This paper explores the tradeoffs between different types of mixed reality robotic communication under different levels of user workload. We present the results of a within-subjects experiment in which we systematically and jointly vary robot communication style alongside level and type of cognitive load, and measure subsequent impacts on accuracy, reaction time, and perceived workload and effectiveness. Our preliminary results suggest that although humans may not notice differences, the manner of load a user is under and the type of communication style used by a robot they interact with do in fact interact to determine their task effectiveness
