Abstract
Systems and methods for six-degree of freedom (6-DoF) pose estimation of a user input device, e.g., in a three-dimensional (3D) system rendering interactive augmented reality (AR) and/or virtual reality (VR) experiences include the user input device capturing, via a camera disposed at a forward-facing tip of the user input device, images in a direction the user input device is directed and providing the images to a computer system. The user input device provides inertial measurement unit (IMU) data to the computer system as well. The computer system may then determine pose information associated with the user input device based on the images and IMU data of the user input device. The determination of the pose information may be via usage of at least one of a neural network model, estimation model trained on a set of unique and identifiable patterns, and/or an estimation model trained on a dataset of images.
