Parallel Ping-Pong: Demonstrating Parallel Interaction through Multiple Bodies by a Single User

We explore a “Parallel Interaction”, where a user controls several bodies concurrently. Here we implemented “Parallel Ping-Pong” as a demonstration of such interaction. The user plays ping-pong by controlling 2 robot arms with a Virtual Reality controller, and while looking from the viewpoint of the robot arms with a Head-Mounted Display. The HMD view is composited by sliding and blending between the viewpoints according to the ping-pong ball direction. To keep the sense of agency over the robot arms (hindered by the system latency), the robot arms calculate the ball path and position themselves to hit the ball back ; all while integrating the controller motion. Throughout this demonstration, we investigate a real-life design of Parallel Interaction with multiple bodies by a single user.
