Devices, methods, systems, and media are described for selecting virtual objects for user interaction in an extended reality environment. Distant virtual objects are brought closer to the user within a virtual 3D space to situate the selected virtual object in virtual proximity to the user's hand for direct manipulation. A virtual object is selected by the user based on movements of the user's hand and/or head that are correlated or associated with an intent to select a specific virtual object within the virtual 3D space. As the user's hand moves in a way that is consistent with this intent, the virtual object is brought closer to the user's hand within the virtual 3D space. To predict the user's intent, hand and head trajectory data may be compared to a library of kinematic trajectory templates to identify a best-matched trajectory template.

A head-mounted display device includes a see-though display providing both eyes of a user with a view of a physical object, a processor, and a non-volatile storage device holding instructions executable by the processor to: display an image that corresponds to the physical object to a first eye of the user at an offset to the physical object; display blocking light to a second eye of the user; in response to alignment user input, move a position of the image relative to the physical object; in response to completion user input, determine the inter-pupillary distance of the user; and calibrate the head-mounted display device based on the inter-pupillary distance.

A three-dimensional (3D) projector includes a 3D display device and a camera. The 3D display device includes a backlight, a display including a display surface, a barrier, and a controller. The camera has an imaging direction that may be a direction of the image light emitted from the display or may be different from the direction of the image light. With the imaging direction of the camera being different from the direction of the image light, the controller performs a process to correct distortion on a captured image output from the camera with reference to the direction of the image light.

A method of generating stereoscopic images for display with respect to a virtual display screen (VDS) position, includes setting a VDS position for a stereoscopic image for display such that the depth profile of one or more VDSs approximates the depth profile of one or more objects in a virtual scene to be displayed by that stereoscopic image, and generating the stereoscopic image for display having image parallax appropriate to the VDS position or positions set by the setting step.

A head-mounted device (HMD) is structured to include at least one computer vision camera that omits an IR light filter. Consequently, this computer vision's sensor is able to detect IR light, including IR laser light, in the environment. The HMD is configured to generate an image of the environment using the computer vision camera. This image is then fed as input into a machine learning (ML) algorithm that identifies IR laser light, which is detected by the sensor and which is recorded in the image. The HMD then visually displays a notification comprising information corresponding to the detected IR laser light.

A method for creating a temporal-spatial dissociation between an ambient visual process and a focal visual process of a user is provided. The method includes rendering, via a parallactic ambient visual-field enhancing (PAVE) module configured to execute on a computing device communicatively coupled to a head mounted display device worn by a user, a fixation target and a background located behind the fixation target displayed within the head mounted display device. The method further includes updating, via the PAVE module, the rendering of the background within the head mounted display device, wherein the update comprises a virtual movement of the background behind the fixation target.

In one embodiment, a computing system may determine, for a current frame to be displayed and using an eye tracking system, a current eye position of a viewer. The system may determine a first array of scaling factors based on the determined current eye position of the viewer. The system may retrieve one or more second arrays of scaling factors used for correcting one or more proceeding frames of the current frame. The system may determine a third array of scaling factors based on the first array of scaling factors determined based on the current eye position and the one or more second arrays of scaling factors used for correcting the proceeding frames. The system may adjust pixel values of the current frame based at least on the third array of scaling factors. The system may output the current frame with the adjusted pixel values to a display.

A three-dimensional display apparatus comprises a display panel (display element) and a parallax barrier (optical element). The display panel displays a left-eye image and a right-eye image respectively in first subpixels and second subpixels. The parallax barrier transmits at least part of the left-eye image toward the left eye, and at least part of the right-eye image toward the right eye. A first certain number of the first subpixels and of the second subpixels are each successively arranged in each column. A region in which the first subpixels are arranged and a region in which the second subpixels are arranged are displaced from each other by a second certain number between two adjacent columns. The first certain number is greater than the second certain number and is not a multiple of the second certain number.

A micro-light emitting diode device includes a backplane including drive circuits formed thereon, an array of micro-LEDs bonded to the backplane and electrically coupled to the drive circuits, an array of polarization diffraction micro-lenses bonded to the array of micro-LEDs and including a planar surface, and a cover glass bonded to the planar surface of the array of polarization diffraction micro-lenses. A center of each polarization diffraction micro-lens of the array of polarization diffraction micro-lenses aligns with a center of a respective micro-LED of the array of micro-LEDs.

A method is provided for the user-specific calibration of a display apparatus, wearable on the head of a user, for an augmented presentation, wherein A), in a basic calibration step, the position of the at least one eye is ascertained relative to the display apparatus in all three spatial directions in the state where the display apparatus is worn on the head of the user and said position is saved in the display apparatus as adjustment data in such a way that an image generating module of the display apparatus generates the image taking account of the adjustment data.
