PointIt: A ROS Toolkit for Interacting with Co-located Robots using Pointing Gestures

We introduce PointIt, a toolkit for the Robot Operating System (ROS2) to build human-robot interfaces based on pointing gestures sensed by a wrist-worn Inertial Measurement Unit, such as a smartwatch. We release the software as open-source with MIT license; docker images and exhaustive instructions simplify its usage in simulated and real-world deployments.
