Active Shadowing (ASD): Manipulating Visual Perception of Robotics Behaviors via Implicit Communication
<|reference_start|>Active Shadowing (ASD): Manipulating Visual Perception of Robotics Behaviors via Implicit Communication: Explicit communication is often valued for its directness during interaction. Implicit communication, on the other hand, is indirect in that its communicative content must be inferred. Implicit communication is considered more desirable in teaming situations that requires reduced interruptions for improved fluency. In this paper, we investigate another unique advantage of implicit communication: its ability to manipulate the perception of object or behavior of interest. When communication results in the perception of an object or behavior to deviate from other information (about the object or behavior) available via observation, it introduces a discrepancy between perception and observation. We show that such a discrepancy in visual perception can benefit human-robot interaction in a controlled manner and introduce an approach referred to as active shadowing (ASD). Through user studies, we demonstrate the effectiveness of active shadowing in creating a misaligned perception of the robot's behavior and its execution in the real-world, resulting in more efficient task completion without sacrificing its understandability. We also analyze conditions under which such visual manipulation is effective.<|reference_end|>
