摘要： Head-worn computers with eye-imaging systems include a camera system positioned in a head-worn computer, wherein the camera system is further positioned to capture eye-image light that originates as reflections from a user's eye, wherein the camera system is further positioned to capture eye-image light as a reflection from a partially reflective surface that is positioned in front of an image display in the head-worn computer, wherein image light, from the image display, is transmitted through the partially reflective surface. A processor is adapted to cause the camera system to capture the eye-image light. The processor is further adapted to cause a comparison of the captured eye-image light with a pre-stored eye image of a known user of the head-worn computer. In the event the comparison confirms the identity of the known user, the user is granted permission to view content to be presented in a display of the head-worn computer.

摘要： Systems, devices, media, and methods are presented for gaze-based control of device operations. One method includes receiving a video stream from an imaging device, the video stream depicting one or more eyes, determining a gaze direction for the one or more eyes depicted in the video stream, detecting a change in the gaze direction of the one or more eyes, and triggering an operation in a client device based on the change in the gaze direction.

摘要： A system for determining a skin tone of a user. Herein, a server arrangement obtains an input image capturing at least a face of the user; analyze the input image to identify at least one first region of the input image that corresponds to a sclera of the user; determine a representative pixel value of the sclera; determine at least one second region of the input image that corresponds to a skin of the user; normalize pixel values of pixels in the at least one second region; determine a representative pixel value of the skin from the normalized pixel values of the pixels in the at least one second region; and select, from amongst a palette of skin tones, a skin tone whose pixel value matches with the representative pixel value of the skin. Herein, the selected skin tone is determined as the skin tone of the user.

摘要： Disclosed is an electronic device including a camera module, a display that displays AR content or VR content, at least one processor operatively connected to the camera module and the display, and a memory operatively connected to the at least one processor and storing the AR content or VR content. The memory may store one or more instructions that, when executed, cause the at least one processor to obtain eye tracking data by using the camera module, to determine an eye fatigue level based on the eye tracking data, and to select one mode between a first mode for changing a setting of the display and a second mode for changing both the setting of the display and an output setting of the AR content or VR content, depending on the eye fatigue level. In addition, other various embodiments identified through the specification are also possible.

摘要： Described are various embodiments of a light field device, pixel rendering method therefor, and vision perception system and method using same. One embodiment describes a method to adjust user perception of an image portion to be rendered via a set of pixels and a corresponding array of light field shaping elements (LFSE), the method comprising: projecting an adjusted image ray trace between a given pixel and a user pupil location to intersect an adjusted image location for a given perceived image depth given a direction of a light field emanated by the given pixel based on a given LFSE intersected thereby; upon the adjusted image ray trace intersecting a given image portion associated with the given perceived image depth, associating with the given pixel an adjusted image portion value designated for the adjusted image location based on the intersection; and rendering for each given pixel the adjusted image portion value associated therewith.
