IMAGE BASED DETECTION OF FIT FOR A HEAD MOUNTED WEARABLE COMPUTING DEVICE
A system and method of detecting display fit measurements and/or ophthalmic measurements for a head mounted wearable computing device including a display device is provided. An image of a fitting frame worn by a user of the computing device is captured by the user, through an application running on the computing device. One or more keypoints and/or features and/or landmarks are detected in the image including the fitting frame. A three-dimensional pose of the fitting frame is determined based on the detected keypoints and/or features and/or landmarks, and configuration information associated with the fitting frame. The display device of the head mounted wearable computing device can then be configured based on the three-dimensional pose of the fitting frame as captured in the image.
Force-Based Peripheral Control Toggle
A smartwatch is configured to be usable to control a peripheral device. The smartwatch can be toggled between a typical or usual operating mode for a smartwatch and a mode for controlling the peripheral device. The toggling function is bound to a virtual button. Force applied to the virtual button is measured so that multiple functions, including the toggling function, can be accessed by applying different amounts of force to the button for a predetermined amount of time.
WORLD LOCK SPATIAL AUDIO PROCESSING
A method for providing a world-locked experience to a user of a headset in an immersive reality application includes receiving, from an immersive reality application, a first audio waveform from a first acoustic source to provide to a user of a headset, determining a direction of arrival for the first acoustic source relative to the headset, and providing, to a speaker in the headset, an audio signal including the first audio waveform and intended for an ear of the user of the headset, wherein the audio signal includes a time delay and an amplitude for the first audio waveform based on the direction of arrival for the first acoustic source relative to the user of the headset. A non-transitory, computer-readable medium storing instructions which, when executed by a processor, cause a system to perform the above method, and the system, are also provided.
WAVEGUIDES WITH INTEGRATED OPTICAL ELEMENTS AND METHODS OF MAKING THE SAME
An example waveguide can include a polymer layer having substantially optically transparent material with first and second major surfaces configured such that light containing image information can propagate through the polymer layer being guided therein by reflecting from the first and second major surfaces via total internal reflection. The first surface can include first smaller and second larger surface portions monolithically integrated with the polymer layer and with each other. The first smaller surface portion can include at least a part of an in-coupling optical element configured to couple light incident on the in-coupling optical element into the polymer layer for propagation therethrough by reflection from the second major surface and the second larger surface portion of the first major surface.
METHOD AND SYSTEM FOR GAZE-BASED CONTROL OF MIXED REALITY CONTENT
Systems and methods are presented for discovering and positioning content into augmented reality space. A method includes forming a three-dimensional (3D) map of surroundings of a user of an augmented reality (AR) head mounted display (HMD); determining a depth-wise location of a gaze point of a user based on eye gaze direction and eye vergence; determining a visual guidance line pathway in the 3D map; guiding an action of the user along the visual guidance line pathway at one or more identified focal points; and rendering a mixed reality (MR) object along the visual guidance line pathway at a location corresponding to a direction of the user’s gaze.
NEAR-EYE DISPLAY BASED ON CONICAL DIFFRACTION
A near-eye display system that employs a volume holographic element containing distinct but overlapped planar volume gratings, each corresponding to a subset of pixels in the display. The volume gratings are illuminated using light incident from angles, and at wavelengths, that match the conical diffraction conditions for each grating, thereby achieving both high diffraction efficiency and a wide field of view. A single volume grating can thus be used to display thousands of pixels independently with high efficiency.
WEARABLE DISPLAY DEVICE AND METHOD FOR ADJUSTING IMAGING SURFACE THEREOF
The present application relates to the technical field of virtual reality. Disclosed are a wearable display device and a method for adjusting an imaging surface thereof. The motor drive assembly in the wearable display device can control the rotation of motors according to a rotation mode carried in a motor control instruction received by a processor, or adjust the rotation speed of the motors according to a speed control parameter carried in the motor control instruction received by the processor. Moreover, the rotation of the motors can adjust the position of an imaging surface, and a change in the position of the imaging face will change the distance between the imaging surface and a user wearing the wearable display device. Therefore, in addition to being used for watching movies or playing games, the wearable display device can also function as an eye protector, and the wearable display device has abundant functions.
DETECTING AND RESPONDING TO LIGHT SOURCE FAILURE
In various examples, a head-mountable display (“HMD”) may include a light source to emit light across a target region of a wearer, a light sensor, and a circuitry operably coupled with the light source and the light sensor. The circuitry may operate the light source to periodically emit light across the light sensor. Based on a determination that a time interval since the circuitry last received a signal from the light sensor satisfies a threshold, the circuitry may trigger a remedial action to cause the light source to cease emission of light across the target region of the wearer.
METHOD AND APPARATUS FOR IDENTIFYING OBJECT OF INTEREST OF USER
The present disclosure relates to methods and apparatuses for identifying an object of interest of a user. One example method includes obtaining information about a line-of-sight-gazed region of the user and an environment image corresponding to the user, obtaining information about a first gaze region of the user in the environment image based on the environment image, where the first gaze region is used to indicate a sensitive region determined by using a physical feature of a human body, and obtaining a target gaze region of the user based on the information about the line-of-sight-gazed region and the information about the first gaze region. The gaze region is used to indicate a region in which a target object gazed by the user in the environment image is located.
