A head-mounted display according to this embodiment includes a left-eye optical system configured to focus display light of a left-eye image from a display element unit on a left eye of a user wearing a head-mounted display, a right-eye optical system placed bilaterally symmetrically to the left-eye optical system and configured to focus display light of a right-eye image from the display element unit on a right eye of the user, and a viewing angle control sheet configured to restrict a spread angle of display light from the display element unit in a left-right direction, and the viewing angle control sheet is fixed to a display surface of the display element unit.

An audio-visual system is shown and describe. The audio-visual system comprises a soundbar and a television monitor assembly. The television monitor assembly comprises a television monitor, a first support and a second support. The first support comprises a first base member and a first vertical member, and the second support comprises a second base member and a second vertical member. The television monitor assembly has one or more free-standing configurations in which the lengths of the first and second base members are substantially perpendicular to the front and rear surfaces of the television monitor and one or more wall-mounted configurations in which the lengths of the first and second base members are substantially parallel to the front rear surfaces of the television monitor. An audio visual system may be provided by attaching a soundbar to the first and second base members in the free-standing configurations.

A display apparatus and an information alert method are disclosed. The method includes: while a first display is playing, controlling, according to acquired alert information, a second display to display an information alert interface, where the alert information displayed on the information alert interface is configured for indicating a state of at least one terminal device connected with the display apparatus.

A mountable video player apparatus for placing video content in photo albums, scrap books, year books, and art includes a housing having a housing front side, a housing back side, a housing top side, a housing bottom side, a housing left side, and a housing right side defining a housing inside. An adhesive layer is coupled to the housing back side to secure the apparatus to a page. A CPU is coupled within the housing inside. A memory chip and a battery are coupled within the housing inside and are in operational communication with the CPU. A display screen is coupled to the housing front side and is in operational communication with the CPU. A plurality of control buttons is coupled within the housing front side and is in operational communication with the CPU.

An observation optical system according to the present invention includes a reflective optical device (30), a first lens group (10), and a second lens group (20). The reflective optical device (30) includes at least one reflection surface (31). The first lens group (10) is disposed at a position closer to an entrance pupil (E.P.) than the reflective optical device (30). The first lens group (10) forms an intermediate image (40) of a virtual image on the reflection surface (31) or at a position closer to the entrance pupil (E.P.) than the reflection surface (31). The intermediate image (40) of the virtual image corresponds to an image displayed on an image display unit (2). The second lens group (20) is disposed on an optical path after light passes through the first lens group (10), the intermediate image (40), and the reflective optical device (30) in order in a case where ray tracing is performed from an entrance pupil (E.P.) side. The second lens group (20) is disposed to cause an image (50) of the entrance pupil (E.P.) to be formed on an optical path after light is reflected by the reflection surface (31).

According to one implementation, a system for supplementing entertainment content with ambient lighting includes a computing platform having a hardware processor and a memory storing a software code. The hardware processor is configured to execute the software code to receive an entertainment content, detect one or more attributes of the entertainment content that correspond to an artistic intent of a producer of the entertainment content, and interpret the artistic intent of the producer of the entertainment content using the detected one or more attributes. The hardware processor is further configured to execute the software code to compose an ambient lighting routine as a supplement to the entertainment content based on the interpreted artistic intent.

A conferencing assembly for sharing content from source devices includes a common display screen, a switcher controlling input to the screen, and a table assembly with a tabletop opening. A control cable assembly has a first end linked to the switcher, a second ends having a plug connectable to a source device communication port, and a first control cable located therebetween. A take up assembly including a first weight is disposed below the opening. The control cable assembly links to the first weight to apply a force tending to pull the second end of the control cable assembly toward the opening. A first user interface including a control button useable to send a signal to the switcher causing it to provide first content from a source device connected to the control cable assembly to the screen is integrated into the table assembly and is associated with the control cable assembly.

A rendering section renders an object in a virtual space to generate a computer graphics image. A post-process section post-processes the computer graphics image. A transmitting and receiving section transmits the post-processed computer graphics image together with depth information to a head mounted display for superimposing the post-processed computer graphics image on a captured image in a real space.
