Other embodiments may be disclosed and/or claimed.

A gaze-tracking system for use in a head-mounted display apparatus, and a method of tracking a user's gaze, via such a gaze-tracking system. The gaze-tracking system includes a plurality of illuminators for emitting light pulses to illuminate a user's eye when the head-mounted display apparatus is worn by the user, the illuminators including at least a first illuminator and a second illuminator; at least one lens positioned on an optical path of reflections of the light pulses from the user's eye, the at least one lens having no chromatic-aberration correction; at least one camera for capturing an image of the reflections of the light pulses; and a processor coupled with illuminators and the at least one camera, the processor being configured to control operations of the illuminators and the at least one camera, and to process the captured image to detect a gaze direction of the user.

Among other thing, the present invention provides solution to the problem, particularly, the present invention provides means to improve the sensitivity, speed, and easy-to-use of a colorimetric assay.

An optical display system and a head-mounted display electronics apparatus are disclosed. The optical display system comprises: an image-generating apparatus, which generates image light; and an image-viewing apparatus, which guides the image light to eyes of a viewer, wherein the image-viewing apparatus comprises an imaging optical assembly and a multifocal assembly placed, the multifocal assembly has at least two optical powers and is programmable to choose at least one of the optical powers at a given time.

The present disclosed subject matter relates to a display device for displaying an image to an eye, comprising a support mounting a light source and a mirror assembly. The light source is configured to emit a visible light beam carrying the image towards the mirror assembly, and the mirror assembly is configured to angularly oscillate and deflect the emitted visible light beam towards the eye. A light sensor is mounted on the support and configured to record return light received via said mirror assembly from the eye. The display device further comprises a processor connected to the light sensor and configured to detect a state of the eye from the recorded return light.

An image projection device includes: one light source unit emitting an image light beam, which forms an image, of visible light and a checking light beam of visible light; an optical system projecting the image light beam emitted from emitted from the one light source unit onto a first surface region of an eye of a user to project the image light beam onto a retina of the user, and projecting the checking light beam emitted from the one light source unit onto a second surface region, which is distant from the first surface region, of the eye of the user; a light detector detecting a reflected light that is the checking light beam reflected by the eye of the user; and a controller controlling at least one of the one light source unit and the optical stem based on a detection result of the reflected light by the light detector.

A foldable light box, including fourth profiles. The fourth profiles are assembled into a frame structure through profile connectors. The inner side walls of the fourth profiles at the upper end and the lower end of the frame structure are connected with lamp bead profiles. The inner side walls of the lamp bead profiles are stuck with LED lamp bead parts through a thermally conductive adhesive. The folding function of the entire light box is achieved by the cooperation of the foldable mechanism and the meshing mechanism provided by the present utility model. As the size is reduced, the light box is more convenient to place and transport, needs less transportation cost and space, and is more convenient to carry and display.

A gaze-tracking system for use in a head-mounted display apparatus, and a method of tracking a user's gaze, via such a gaze-tracking system. The gaze-tracking system includes a plurality of illuminators for emitting light pulses to illuminate a user's eye when the head-mounted display apparatus is worn by the user, the illuminators including at least a first illuminator and a second illuminator; at least one lens positioned on an optical path of reflections of the light pulses from the user's eye, the at least one lens having no chromatic-aberration correction; at least one camera for capturing an image of the reflections of the light pulses; and a processor coupled with illuminators and the at least one camera, the processor being configured to control operations of the illuminators and the at least one camera, and to process the captured image to detect a gaze direction of the user.

An inflatable light box includes securing plates and panels in association with upper and lower interior connecting planks when coupled to a cylindrical barrel in which an inflatable airbag is disposed, and encompassed by a decorative cover, form a housing for an inflatable light apparatus.
