Head-mounted display systems may include an eye-tracking subsystem and a fixation distance prediction subsystem. The eye-tracking subsystem may be configured to determine at least a gaze direction of a user's eyes and an eye movement speed of the user's eyes. The fixation distance prediction subsystem may be configured to predict, based on the eye movement speed and the gaze direction of the user's eyes, a fixation distance at which the user's eyes will become fixated prior to the user's eyes reaching a fixation state associated with the predicted fixation distance. Additional methods, systems, and devices are also disclosed.

The present invention relates to a stereo eye tracking technique. The eye tracking device comprises a processing unit configured and operable for receiving at least one image being indicative of a user's eye; identifying in the image a first data being indicative of pupil's parameters; receiving a second data being indicative of an alternative eye tracking, wherein the second data is more accurate than the first data; and correlating between the first and second data and determining a three-dimensional position and gaze direction of the user's eye.

Three-dimensional models (or avatars) may be defined based on imaging data captured from a customer. The avatars may be based on a virtual mannequin having one or more dimensions in common with the customer, a body template corresponding to the customer, or imaging data captured from the customer. The avatars are displayed on displays or in user interfaces and used for any purpose, such as to depict how clothing will appear or behave while being worn by a customer alone or with other clothing. Customers may drag-and-drop images of clothing onto the avatars. One or more of the avatars may be displayed on any display, such as a monitor or a virtual reality headset, which may depict the avatars in a static or dynamic mode. Images of avatars and clothing may be used to generate print catalogs depicting the appearance or behavior of the clothing while worn by the customer.

An eye tracking device for tracking an eye is described. The eye tracking device comprises: a first diffractive optical element, DOE, arranged in front of the eye, an image module, wherein the image module is configured to capture an image of the eye via the first DOE. The first DOE is adapted to direct a first portion of incident light reflected from the eye, towards the image module. The eye tracking device is characterized in that the first DOE is configured to provide a lens effect.

The invention pertains to methods and apparatus for compensating the rendering of virtual content in an augmented reality scene as a function of the white point, spectral distribution, color or other optical parameter of the real content in the scene.

Systems and methods for controlling a head-up display (HUD) in a vehicle are disclosed herein. One embodiment deactivates the HUD in response to a command from a driver of the vehicle; assigns a level of urgency to an item of information associated with a current vehicular context; and activates the HUD to display the item of information to the driver, when the level of urgency exceeds a predetermined threshold.

A system and method capture a spatial orientation of a wearable device. The system has at least one capturing unit and at least one processor unit. The at least one capturing unit is designed to capture at least one first position parameter in relation to the wearable device and to capture at least one second position parameter in relation to a body part of a person on which the wearable device is arranged. The at least one processor unit is designed to determine a spatial orientation of the wearable device on the basis of the at least one first position parameter and the at least one second position parameter.

Systems and methods for depth plane selection in display system such as augmented reality display systems, including mixed reality display systems, are disclosed. A display(s) may present virtual image content via image light to an eye(s) of a user. The display(s) may output the image light to the eye(s) of the user, the image light to have different amounts of wavefront divergence corresponding to different depth planes at different distances away from the user. A camera(s) may capture images of the eye(s). An indication may be generated based on obtained images of the eye(s), indicating whether the user is identified. The display(s) may be controlled to output the image light to the eye(s) of the user, the image light to have the different amounts of wavefront divergence based at least in part on the generated indication indicating whether the user is identified.

A bicycle system with omnidirectional viewing having front-facing, stereoscopic video camera devices relying on computer vision. The front-facing, stereoscopic video camera devices positioned on the bicycle help identify, classify, and recommend a safe trajectory around obstacles in real-time using augmented reality. The bicycle system details safety-related and guidance-related information.

An HMD device is configured to vertically adjust the ground plane of a rendered virtual reality environment that has varying elevations to match the flat real world floor so that the device user can move around to navigate and explore the environment and always be properly located on the virtual ground and not be above it or underneath it. Rather than continuously adjust the virtual reality ground plane, which can introduce cognitive dissonance discomfort to the user, when the user is not engaged in some form of locomotion (e.g., walking), the HMD device establishes a threshold radius around the user within which virtual ground plane adjustment is not performed. The user can make movements within the threshold radius without the HMD device shifting the virtual terrain. When the user moves past the threshold radius, the device will perform an adjustment as needed to match the ground plane of the virtual reality environment to the real world floor.
