摘要： A mixed reality system may comprise a base station, affixed to an object, that emits an electromagnetic field (EMF) and a head-mounted display (HMD) device with a location sensor and an EMF sensor mounted a predetermined offset therefrom. The base station and EMF sensor together may form a magnetic tracking system. The HMD device may determine a relative location of the EMF sensor based on sensing the EMF and determine a location of the base station in space based on the relative location, the predetermined offset, and the location of the location sensor. An optical tracking system comprising a marker and an optical sensor may be included to augment the magnetic tracking system based on captured optical data and a location of the optical sensor or marker. The HMD device may display augmented reality images and overlay a hologram corresponding to the location of the base station over time.

摘要： In embodiments of a camera-based input device, the input device includes an inertial measurement unit that collects motion data associated with velocity and acceleration of the input device in an environment, such as in three-dimensional (3D) space. The input device also includes at least two visual light cameras that capture images of the environment. A positioning application is implemented to receive the motion data from the inertial measurement unit, and receive the images of the environment from the at least two visual light cameras. The positioning application can then determine positions of the input device based on the motion data and the images correlated with a map of the environment, and track a motion of the input device in the environment based on the determined positions of the input device.
