Techniques for intelligently identifying what type of moving platform an MR system is operating on are disclosed. A display artifact that is associated with content displayed by the MR system is detected. A determination is made that a current configuration of a motion model used to display the content is causing the display artifact. Time-limited series of convoluted motion data is analyzed. The time-limited series of convoluted motion data is fed as input to a predictive ML algorithm. The predictive ML algorithm determines a particular category for the moving platform based on the time-limited series of convoluted motion data. Based on the determined category, either a reconfigured version of the motion model is used or a new motion model is used to display a hologram.

Automatic detection of the presence of a moving platform

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

Techniques for enabling a library of local maps to remain de-coupled from a global map are disclosed. An MR system is determined to be located on a platform that is currently moving or that has an ability to readily move. That platform's type is determined. Based on the determined type for the platform, a 3D boundary that approximates a shape for the platform's type is generated. The 3D boundary is imposed on the platform. Scanning data for the platform is acquired. The bounds for that scanning data is at least initially limited to that of the 3D boundary. The scanning data is used to build or supplement a library of local maps. The library is representative of the platform. That library is prevented from being coupled to a global map.

Enabling a local mixed reality map to remain de-coupled from a global mixed reality map

A method to control an output component of an electronic system comprises (a) receiving a transmission from an input component of the electronic system, the transmission including a time stamp and at least one input signal; (b) storing content of the transmission including the time stamp and the at least one input signal; (c) selecting one of a plurality of noise-filtered signals based on the time stamp and on a reference time index, the selected one of the plurality of noise-filtered signals having a greatest signal-to-noise ratio among the noise-filtered signals defined at the reference time index; and (d) controlling an output component of the electronic system based in part on the selected noise-filtered signal.
