  We propose SlingDrone, a novel Mixed Reality interaction paradigm that
utilizes a micro-quadrotor as both pointing controller and interactive robot
with a slingshot motion type. The drone attempts to hover at a given position
while the human pulls it in desired direction using a hand grip and a leash.
Based on the displacement, a virtual trajectory is defined. To allow for
intuitive and simple control, we use virtual reality (VR) technology to trace
the path of the drone based on the displacement input. The user receives force
feedback propagated through the leash. Force feedback from SlingDrone coupled
with visualized trajectory in VR creates an intuitive and user friendly
pointing device. When the drone is released, it follows the trajectory that was
shown in VR. Onboard payload (e.g. magnetic gripper) can perform various
scenarios for real interaction with the surroundings, e.g. manipulation or
sensing. Unlike HTC Vive controller, SlingDrone does not require handheld
devices, thus it can be used as a standalone pointing technology in VR.
