A wireless position tracking device, a display system, and a wearable device are provided. The wireless position tracking device includes a rigid body, point light sources, a motion sensor, and a wireless transmission module. The rigid body has an inner concave surface, a head, a connecting portion, and a tail. The connecting portion connects the head and tail. The point light sources are fixed to positions outside the inner concave surface. The motion sensor locates in the rigid body for sensing a motion thereof and generating motion information. The wireless transmission module locates in the rigid body and electrically connects the motion sensor for wirelessly transmitting the motion information to the head-mounted device. An image capturing module of the head-mounted device captures a pattern formed by the point light sources. The head-mounted device calculates a relative position of the wireless position tracking device according to the pattern and motion information.

Multiple head-mounted devices and/or other electronic devices can operate in concert to provide multiple users with shared experiences and content enjoyment. Such operations can be facilitated by a connection between multiple head-mounted devices and/or other electronic devices to allow different users to receive content. Such a connection can be made possible by a connector that directly and physically connects head-mounted devices and/or other electronic devices to each other and transmits signals there between. By providing a physical connection, the signals can be efficiently transmitted even when other types of connections (e.g., wireless) are not available

A head-mountable device can include modules that provide fit adjustment capabilities when assembled together. By providing a head-mountable device with modular features, certain modules can provide fit adjustment capabilities without requiring other modules to be custom designed or available in a wide variety of sizes and/or shapes. The head-mountable device and/or other electronic devices can be operated to guide a user to select the optimal light seal module for use with an HMD module. For example, the head-mountable device or another device can include sensors for detecting features of the user's face, forces distributed on the face when worn, and/or entry of light from an external environment.

While head-mountable devices can provide immersive experiences, a user wearing a head-mountable device can also benefit from activities that include body motion and promote the user's health. Because such activities may not be intrinsically necessary to the operation of head-mountable devices, it can be beneficial to provide additional or modified operations that allow a user to continue operation of a head-mountable device while performing the desired body motions. The head-mountable device can detect movement and/or stasis of the user and determine whether motion would be recommended. Upon determining that motion, an additional motion, or a different motion would be beneficial, the head-mountable device can provide an output to the user that promote such motions. The output can include a notification to the user and/or a modification of the user interface that encourages the user to move in a particular way.

An image processing device of an embodiment includes a control unit that generates a composite image and outputs the composite image to a display device, the composite image being acquired by combination of a first image captured in first exposure time and having first resolution, and a second image that is an image corresponding to a part of a region of the first image, and that is captured in second exposure time shorter than the first exposure time and has second resolution higher than the first resolution, the first image and the second image being input from an image sensor.

A headset apparatus configured to be worn by a user operating outdoor power equipment. The headset may include a noise cancelling system and/or enhanced glasses.

A lens specification for multiple lens layers of a lens structure is generated by one or more processors. A multifocal correction (MFC) component is assigned to at least one lens layer of the multiple lens layers. Parameters are generated for a display optics (DO) lens layer comprising an augmented reality (AR) display, the DO lens layer having a first side for facing an eye of the user and a second side for facing away from the eye of the user. Parameters are generated for one or more eye side (ES) lens layers of the multiple lens layers to be disposed adjacent to the first side of the DO lens layer, and for one or more world side (WS) lens layers to be disposed adjacent to the second side of the DO lens layer. The generated lens specification is provided for use in production of the lens structure for the user.

A system for displaying a stereo image is disclosed. The system includes a stereoscopic head up display (HUD) that includes a combiner and a display configured to display a stereo image. The system further includes either a head tracking sensor or an eye tracking sensor configured to generate a tracking dataset. The system further includes a processor and a memory with instructions that cause the processor to receive the tracking dataset, generate a distortion map based on the tracking dataset and a distortion function, receive a media stereo image, generate a stereo signal based on the distortion map and the media stereo image, and transmit the stereo signal to the display. The system is capable of conveying an image to an operator in the absence of a relay lens.

Some embodiments of the present disclosure relate to a heads-up display (HUD) system. The HUD system may include a transparent support structure, an electrochromic element, and a HUD controller. The electrochromic element may be affixed to a surface of a transparent material. The HUD controller may be electrically coupled to the electrochromic element and configured to control translucence of the electrochromic element via control signals.

An optical element includes a transparent layer, outcoupling elements, and a waveguide structure. The outcoupling elements are positioned across the transparent layer. The waveguide structure provides non-visible light to the outcoupling elements and the outcoupling elements outcouple the non-visible light as non-visible illumination light to illuminate an eye region.
