An imaging method is provided for a modular mixed reality (MR) device having an MR calculation module, an MR optical path module and an MR posture module. The MR calculation module is configured to adjust display content according to data from the MR posture module. The MR optical path module comprises a virtual-image optical path and a mixed optical path. A semi-transparent semi-reflective mirror is provided in the mixed optical path. One surface of the mirror is a real-image introduction surface facing a real environment, while the other is a virtual-image introduction surface facing the virtual-image optical path. Virtual-image light is reflected by the virtual-image introduction surface onto an observation end and mixed with real environment light transmitted to the observation end by the real-image introduction surface to form a mixed reality image.

In one implementation, a non-transitory computer-readable storage medium stores program instructions computer-executable on a computer to perform operations. The operations include presenting, on a display of an electronic device, first content representing a standard view of a physical setting depicted in image data generated by an image sensor of the electronic device. While presenting the first content, an interaction with an input device of the electronic device is detected that is indicative of a request to present an enriched view of the physical setting. In accordance with detecting the interaction, second content is formed representing the enriched view of the physical setting by applying an enrichment effect that alters or supplements the image data generated by the image sensor. The second content representing the enriched view of the physical setting is presented on the display.

Head-mounted augmented reality (AR) devices can track pose of a wearer's head to provide a three-dimensional virtual representation of objects in the wearer's environment. An electromagnetic (EM) tracking system can track head or body pose. A handheld user input device can include an EM emitter that generates an EM field, and the head-mounted AR device can include an EM sensor that senses the EM field. EM information from the sensor can be analyzed to determine location and/or orientation of the sensor and thereby the wearer's pose. An improved or optimized pose can be provided by reverse-estimating a reverse EM measurement matrix and optimizing the pose based on a comparison between the reverse EM measurement matrix and an EM measurement matrix measured by the EM sensor.

A method which makes it possible to immerse a user in a virtual reality application is described. The method includes controlling the movement of an avatar of a user in a synthetic scene and controlling the movements of a video acquisition system depending on the detected movements of the head of the user. The method also includes playing back content on a screen of a virtual reality helmet of the user, the content being a video stream acquired by the video acquisition system if the position of the eyes of the avatar is in a synthetic object whose volume can be included in a volume in which the video acquisition system is likely to move.

A virtual or augmented reality display system can include a first sensor to provide measurements of a user's head pose over time and a processor to estimate the user's head pose based on at least one head pose measurement and based on at least one calculated predicted head pose. The processor can combine the head pose measurement and the predicted head pose using one or more gain factors. The one or more gain factors may vary based upon the user's head pose position within a physiological range of movement.
