Abstract
A virtual reality (VR) system tracks the position of a controller. The VR system includes an image tracking system comprising of a number of fixed cameras, and a headset worn by the user that includes an imaging device to capture images of a controller operated by the user. The controller includes a set of features disposed on the surface of the controller. The image tracking system provides a first view of the controller. The imaging device mounted on the headset provides a second view of the controller. Each view of the controller (i.e., from the headset and from the image tracking system) provides a distinct set of features observed on the controller. The first and second sets of features are identified from the captured images and a pose of the controller is determined using the first set of features and the second set of features.
