Abstract: 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.

Abstract: Systems are provided that include a wireless hand-held inertial controller with passive optical and inertial tracking in a slim form-factor. These systems are configured for use with a head mounted virtual or augmented reality display device (HMD) that operates with six degrees of freedom by fusing (i) data related to the position of the controller derived from a forward-facing optical sensor located in the HMD with (ii) data relating to the orientation of the controller derived from an inertial measurement unit located in the controller.

Abstract: A mixed reality system may comprise a head-mounted display (HMD) device with a location sensor and a base station, mounted a predetermined offset from the location sensor, that emits an electromagnetic field (EMF). An EMF sensor affixed to an object may sense the EMF, forming a magnetic tracking system. The HMD device may determine a relative location of the EMF sensor therefrom and determine a location of the EMF sensor in space based on the relative location, the predetermined offset, and the location of the location sensor. An optical tracking system comprising a marker an optical sensor configured to capture optical data may be included to augment the magnetic tracking system based on the 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 EMF sensor over time.

Abstract: In embodiments of augmenting a moveable entity with a hologram, an alternate reality device includes a tracking system that can recognize an entity in an environment and track movement of the entity in the environment. The alternate reality device can also include a detection algorithm implemented to identify the entity recognized by the tracking system based on identifiable characteristics of the entity. A hologram positioning application is implemented to receive motion data from the tracking system, receive entity characteristic data from the detection algorithm, and determine a position and an orientation of the entity in the environment based on the motion data and the entity characteristic data. The hologram positioning application can then generate a hologram that appears associated with the entity as the entity moves in the environment.
