Various implementations disclosed herein include electronic devices, systems, and methods that detect reflections of light produced by a plurality of light sources reflected from an eye. An example electronic device may include a frame, an image sensor, a transparent substrate coupled to the frame, a waveguide coupled to the transparent substrate, and a processor coupled to the plurality of IR light sources. The transparent substrate may include a plurality of infrared (IR) light sources that may be configured in a spatial arrangement within the transparent substrate or on a surface of the transparent substrate. The waveguide may be configured to display a projected image. The processor may be configured to receive sensor data from the image sensor. The sensor data may correspond to a plurality of reflections of light produced by the plurality of IR light sources and reflected from an eye.

Eye reflections using IR light sources on a transparent substrate

A head-mounted display may include a display system and an optical system in a housing. The display system may have displays that produce images. Positioners may be used to move the displays relative to the eye positions of a user's eyes. An adjustable optical system may include tunable lenses such as tunable cylindrical liquid crystal lenses. The displays may be viewed through the lenses when the user's eyes are at the eye positions. A sensor may be incorporated into the head-mounted display to measure refractive errors in the user's eyes. The sensor may include waveguides and volume holograms, and a camera for gathering light that has reflected from the retinas of the user's eyes. Viewing comfort may be enhanced by adjusting display positions relative to the eye positions and/or by adjusting lens settings based on the content being presented on the display and/or measured refractive errors.

Head-mounted display device with vision correction

Hot word free adaptation, of function(s) of an automated assistant, responsive to determining, based on gaze measure(s) and/or active speech measure(s), that a user is engaging with the automated assistant. Implementations relate to techniques for mitigating false positive occurrences of and/or false negative occurrences, of hot word free adaptation, through utilization of a permissive parameter set in some situation(s) and a restrictive parameter set in other situation(s). For example, utilizing the restrictive parameter set when it is determined that a user is engaged in conversation with additional user(s). The permissive parameter set includes permissive parameter(s) that are more permissive than counterpart(s) in the restrictive parameter set. A parameter set is utilized in determining whether condition(s) are satisfied, where those condition(s), if satisfied, indicate that the user is engaging in hot word free interaction with the automated assistant and result in adaptation of function(s) of the automated assistant.

Techniques related to generating holographic images for a holographic heads up display are discussed. Such techniques include application of a machine learning model to the target image to generate data that is used to enable the determination of a phase pattern via an iterative propagation feedback model. The iterative propagation feedback model is used to generate a feedback strength value, which is then used to generate a phase diffraction pattern for presentation at a holographic plane of the heads up display.

Methods and apparatus for using polarized light (e.g., infrared (IR) light) to improve eye-related functions such as iris recognition. An eye camera system includes one or more IR cameras that capture images of the user's eyes that are processed to perform iris recognition, gaze tracking, or other functions. At least one polarizing element may be located in the path of the light which is used to capture images of the user's eye. The user's eye may be illuminated by IR light emitted by one or more LEDs. At least one of the LEDs may be an LED with a polarizing filter.
