Systems and methods are provided for using a user wearable device having a first radar array configured to perform elevation mapping of a three-dimensional environment and a second radar array configured to perform azimuthal mapping of the three-dimensional environment which is divided into a plurality of voxels. Based on a detected triggering condition of the radar arrays, systems and methods are provided for dynamically updating at least a sub-set of voxels of the plurality of voxels in the three-dimensional environment at a new voxel granularity configured to facilitate an improvement in a resolution of one or more features included in the three-dimensional environment.

Synthetic aperture radar for head mounted displays

Techniques include performing a calibration of the display with respect to the eye-tracking camera after usage. The calibration involves determining a current position of a reflected pixel of the display within a field of view of the eye-tracking camera and comparing that position with a calibration position, for example a position seen at the factory. The pixel may then be shifted according to the difference between the current position and the calibration position.

Examples are disclosed that relate to sensing a position of a surface proximate to a resonant LC sensor. One example provides a method on a sensing device comprising one or more resonant LC sensors each configured to output a signal responsive to a position of a surface proximate to the resonant LC sensor. The method comprises, for each LC sensor, generating an oscillating signal on an antenna of the resonant LC sensor and detecting a near-field response of the resonant LC sensor at a selected frequency.

Surface sensing via resonant sensor

To track an object with radar, and achieve greater than range resolution precision, the phase of a difference signal can be utilized and adjusted as the tracked object crosses between resolution ranges. Changes in the object's distance can be detected with greater than range resolution precision by utilizing the phase. Such changes can iteratively inform the determined distance across multiple phase cycles within a single distance range. As the movement of the object approaches, and then crosses, between resolution ranges, the phase as determined within an origin resolution range can be compared with a coincident phase within the destination resolution range and the difference can then be utilized to adjust the phase as the object then remains within the destination resolution range. Such phase adjustments can be applied across multiple resolution ranges, allowing for the tracking of an object, utilizing radar, while achieving greater than range resolution precision.

Radar tracking with greater than range resolution precision

Systems and methods are provided for tracking a passive controller system using an active sensor system within a mixed-reality environment. The passive controller system includes a body configured to be held in a hand of a user, as well as a plurality of retroreflectors that collectively provides at least 180 degrees of reflecting surface for reflecting a radar signal in at least 180 degrees of spherical range when the passive controller system is positioned within a predetermined distance from a source of the radar signal and with an orientation that is within the at least 180 degrees of spherical range relative to the source of the radar signal. Signals transmitted to the passive controller and reflected back from the passive controller are used to calculate the position and orientation of the passive controller system relative to the active sensor system.

A messaging gamification device. A messaging gamification device can include a customizable message provisioning system and a customizable display system. A method of operating a messaging gamification device can include controlling reproduction of content on a customizable display system of the gamification device according to how a user interacts with the gamification device and content presentation rules.

Examples of mixed reality computing devices that utilize remote sensors and local sensors as input devices are disclosed. In one example, a mixed reality computing device comprises an image sensor, a remote input device, a processor, and storage comprising stored instructions. The stored instructions are executable by the processor to perform object motion tracking and environmental tracking based on output from the image sensor, and in response to detecting that the remote input device is in use, adjust a parameter of the motion tracking while maintaining the environmental tracking.

Object motion tracking with remote device

A system determines the transmission strength of the magnetic field signal. The magnetic field signal is transmitted from a first magnetic-sensor device to a second magnetic-sensor device. The system then determines a first projected distance between the first magnetic-sensor device and the second magnetic-sensor device. Based at least in part on the first projected distance, the system calculates an adjusted transmission strength for the magnetic field signal. The system then causes the first magnetic-sensor device to transmit an adjusted magnetic field signal. The adjusted magnetic field signal comprises the adjusted transmission strength. The system receives, from the second magnetic-field device, the adjusted magnetic field signal. Based at least in part upon the received adjusted magnetic field signal, the system, computes a first pose of the first magnetic-sensor device in relation to the second magnetic-sensor device.

Dynamic transmitter power control for magnetic tracker

A mixed-reality system causes a magnetic transmission device to transmit a magnetic field signal. The mixed-reality system also causes a magnetic-field sensing device to determine a measurement of the magnetic field signal. The mixed-reality system then identifies, using one or more input devices, that a magnetically-interfering object is located within a same environment as both the magnetic transmission device and the magnetic-field sensing device. The mixed-reality system also determines one or more characteristics of magnetic field interference that the magnetically-interfering object is imparting on the magnetic transmission device or the magnetic-field sensing device. The mixed-reality system then computes an adjustment to a pose-estimation model based upon the one or more characteristics of magnetic field interference. The pose-estimation model is used to calculate a pose of at least one of the magnetic transmission device or the magnetic-field sensing device.

Magnetic interference detection and correction

A system of a transmitter and a receiver uses magnetic fields to determine the relative position and orientation, or pose, of the two devices. For example, the transmitter could be a handheld control device and the receiver could be an augmented reality or other computing solution. The transmitter transmits two magnetic fields of differing frequencies and differing amplitudes. The receiver selects the one of the magnetic fields with the higher signal to noise ratio to determine the relative pose of the transmitter. By using two magnetic fields of different amplitudes, the pose can be determined over a wider range of separations.
