A method of tracking 3D position and orientation of an entity in a moving platform is described. The method comprises receiving data sensed by an inertial measurement unit mounted on the entity. Visual tracking data is also received, computed from images depicting the moving platform or the entity in the moving platform. The method computes the 3D position and orientation of the entity by estimating a plurality of states using the visual tracking data and the data sensed by the inertial measurement unit, where the states comprise both states of the moving platform and states of the entity.

Tracking in a moving platform

A computer implemented method includes capturing images of an environment via a camera, detecting image features in the environment based on the captured images, the image features including at least one web feature derived from a fiducial web formed of a collection of non-repeating intersecting lines applied to an object in the environment, and estimating a camera pose based on the detected image features including the at least one web feature.

Fiducial web for computer vision

In one embodiment, a user device may reestablish access to a user resource while forgoing use of a user credential during a system reboot. The user device may receive the user credential from a user during an initial login to access the user resource. The user device may create an ephemeral entropy to access the user resource. The user device may access the user resource using the ephemeral entropy.

Resumption of logon across reboots

Data sharing session techniques are described. In one or more implementations, a first user login session is initiated as running in a context of a first user profile of a first user with an operating system of a computing device. A request is received by the operating system to run the first user login session in a context of a second user profile of a second user. The second user profile is associated by the operating system with a shadow login session created within the first user login session of the operating system of the computing device such that interaction of the second user with the operating system is associated with the second user profile and interaction of the first user with the operating system is associated with the first user profile.
