摘要： An electronic device may display, by using a viewfinder picture in an augmented reality (AR) application interface, an object that is in the real world in which a user is located and that is collected by a camera. The user may enable, by performing an operation, the AR application to generate a mask in an area in which a first object is located in the viewfinder picture to block the first object. Then, a three-dimensional representation of a second object is projected onto the mask, where the second object is in a field of view range of the area in which the first object is located.

摘要： A terminal with a line-of-sight tracking function is disclosed. The terminal with a line-of-sight tracking function includes a body, a camera, and at least two light emitting diodes. The camera and the at least two light emitting diodes are mounted on the body, so that the terminal can emit a ray by using the at least two light emitting diodes, to ensure that the emitted ray can be shined on an eye of the user when the user is at different angles. After the ray is reflected by the eye of the user, the terminal can collect the reflected ray by using the camera, obtain an eye image of the user, and track a line of sight of the user based on the eye image, thereby increasing a success rate of line-of-sight tracking.

摘要： The disclosure provides a display device for head mounting, in particular a Maxwellian display device, with an enlarged eye-box. The display device includes a light source emitting light beams for forming an image, an optical system for guiding the light beams to a beam forming element. The beam forming element is configured to converge each of multiple sets of the light beams into a different point of convergence, for example on an exit pupil of the display device. Each point of convergence is a convergent viewing point for a user. The eye-box is thus enlarged.
