Techniques are provided for measuring interpupillary distance (IPD) using a mobile device application that integrates with augmented reality (AR) eyewear. The mobile application guides users through a measurement process using the device's camera and sensors to capture facial data. Computer vision algorithms analyze the data to determine IPD measurements while considering facial geometry and depth perception. The system provides real-time positioning feedback and allows manual entry of known IPD values. Measurements are stored in user profiles rather than on AR devices, enabling cross-device synchronization. The integration of IPD measurement into the initial device setup process, combined with flexible measurement options and profile-based storage, provides an accessible solution that maintains accuracy while eliminating the need for specialized measurement hardware.

The invention relates to a three-dimensional face high-fidelity texture generation method based on a multi-view high-definition image, and the method comprises the steps: constructing a three-dimensional face triangular mesh model through employing a camera fusion weight and an external parameter based on the cosine square of a view angle, and solving a texture mixed weight of each camera to a mesh triangular patch; the cylindrical UV expansion method is used for adapting to the geometrical characteristics of the human face, so that the texture stretching distortion can be obviously reduced; high-frequency detail reservation and low-frequency hue smooth transition are achieved through a frequency-band-divided texture fusion strategy, a high-quality texture source is optimized in cooperation with view angle cosine square weight and depth shielding detection, and fusion joints and detail dilution are avoided.

A facemask assembly can include an interior air filter that is replaceable and / or contains biocidal elements. The filter can capture exhaled H2O to activate silver ions creating a biocidal environment. In some embodiments, at least part of the facemask is made via additive manufacturing. A facemask frame assembly can create a pleated filter to increase surface area and bring the filter material closer to the mouth and nose. The facemask can include a facial skirt customized to the facial geometry of the wearer. The facemask can have a permanently sealed filter than can withstand boiling and autoclaving temperatures so the mask system can be sterilized without disassembly. In some embodiments, the facemask has a visible display of how many times the facemask has been sterilized. In some embodiments, the mask includes a RFID device that can transmit how many times the facemask has been sterilized.

Systems and methods to custom-design gaskets for a virtual reality (VR) interface, wherein the VR interface includes a head mounted display (HMD) to be worn by users are disclosed. Exemplary implementations may obtain facial geometry information for a user's face; generate a representation of the surface of the user's face, based on the facial geometry information; align the representation with a representation of the HMD; generate a model of a three-dimensional gasket that fits between the representation of the surface of the user's face and the representation of the HMD; export and / or present the model of the three-dimensional gasket; and / or perform other steps. Such custom-designed gaskets may provide an improved fit with better optical alignment when compared to mass-produced gaskets.

A three-dimensional head model generation method based on 2D facial expression analysis includes four steps of expression analysis, occlusion processing, multi-angle image generation and 3D model optimization. First, the expression parameters are extracted by the expression recognition model, and the expression is neutralized to generate expressionless images. Then, the image segmentation and deep learning inpainting technology are used to automatically identify and remove the occlusion, and the facial texture continuity is maintained. Then, multi-angle views are generated from the unoccluded neutral expression images to ensure the consistency of facial geometry and texture. Finally, the differentiable rendering technology is used to optimize the shape and map of the 3D model, realizing high consistency with the 2D image, so as to obtain high-precision and high-fidelity 3D head model. The multi-angle optimization method combines differentiable rendering with deep learning to improve the accuracy and consistency of 3D model generation. The neutral expression generation reduces geometric distortion, and the automatic removal of occlusion effectively improves the accuracy of facial reconstruction. It has strong practical value.

Abstract A patient interface, such as a nasal cannula, for delivering breathable gas to a user is disclosed. The interface includes a body configured to be positioned on a user’s face and one or more nasal prongs fluidly connected to a gas supply for insertion into, or directing gas toward, the user’s nares. The body incorporates at least one force- or movement-responsive element configured to react to forces or movements experienced in a first region of the interface. The element is deformable or articulated and operates to isolate, absorb, dampen, or otherwise reduce transfer of such forces or movements to other regions of the interface. This localised response stabilises the position of the nasal prongs relative to the nares, maintaining a desired therapy delivery configuration despite external disturbances or changes in facial geometry. The responsive element may comprise hinges, pivots, joints, or regions of preferential flexibility or deformation, and may be arranged, for example, in a bridge region between body portions. Multiple elements may be combined to provide coordinated responses. The interface thereby enhances comfort and positional stability during use. Abstract

The present invention proposes a three-dimensional face reconstruction method based on a depth-guided two-stream network, constructs an end-to-end depth-guided two-stream network, and improves the robustness and generalization in complex environments. This method integrates image and depth prior information to enhance the performance of the reconstruction system under complex backgrounds, extreme lighting and large postures. Specifically: a facial geometry perception module is designed to generate accurate facial masks using image semantic features and depth priors to suppress background interference; a bidirectional cross-attention module is introduced to achieve efficient fusion of RGB and depth information and enhance feature representation capabilities; key modules work together to alleviate depth ambiguity problems, generate high-quality UV position maps and texture maps, and obtain high-precision three-dimensional face representations. This method outperforms mainstream methods in multiple evaluation indicators, especially in difficult scenes such as complex backgrounds, verifying the effectiveness, robustness and application potential of the framework, and providing technical innovation and practical value for face reconstruction in extreme environments.
