An image projection apparatus includes a first image irradiation unit, a light guide plate unit, and a diffraction grating unit. The first image irradiation unit is configured to emit first light. The light guide plate unit includes a first light incidence unit, an optical waveguide unit, and a first light emission unit. The first light incidence unit on which the first light is incident. The optical waveguide unit is configured to guide a part of the first light as guided light while totally reflecting the part of the first light. The first light emission unit is configured to emit a part of the guided light in a viewpoint direction. The diffraction grating unit is provided in the first light incidence unit. The first light emission unit includes a beam splitter provided in the optical waveguide unit and a retroreflection unit provided at an end of the optical waveguide unit.

An intelligent television system provides an operating system and an application framework for controlling a user interface to handle user input events from a handheld remote control. The remote control includes color keys that are configured for triggering different functions in different application panels displayed on the television.

A display device includes a frame that includes a front portion, temple portions, and a pad portion, and is mounted on head of an observer, and an image display device attached to the frame. The image display device includes an image forming device, and an optical device on which light emitted from the image forming device is incident and from which the light is emitted toward the observer. One end portion of the optical device is fixed to a temple portion side of the front portion. Other end portion of the optical device is on a pad portion side of the front portion. A light shielding member that prevents external light from being incident on the other end portion of the optical device from above the other end portion of the optical device is attached to the pad portion side of the front portion.

A false window unit includes: a window frame which is disposed in a wall and includes an opening; an image display device which is disposed facing the opening of the window frame, and displays a landscape image toward the indoor space through the opening of the window frame; a light source which is disposed between the window frame and the image display device, and emits light simulating sunlight toward the indoor space through the opening of the window frame; and a sash frame which blocks part of the light from the light source.

A display control apparatus for controlling display of a display device that a user can wear acquires speech collected by a plurality of microphones, estimates a sound-arrival direction of the acquired speech, and generates a text image corresponding to the acquired speech. The display control apparatus determines an adjustment amount of a display position of the text image on the display unit of the display device based on a detection result of at least one of an operation by the user and a state of the display device. Then, the display control apparatus displays the generated text image at a display position in the display unit, the display position being determined in accordance with the estimated sound-arrival direction and the determined adjustment amount.

A wireless power transmitter includes a first inductive element featuring a planar coil occupying a first plane and having first and second terminals, a first capacitive element connected to the first terminal, an inverter configured to provide an oscillating voltage signal to the first inductive element, through the first capacitive element, such that the first inductive element generates an oscillating magnetic field for transmitting power in response to the oscillating voltage signal, and a layer of magnetic material, disposed over the planar coil in a second plane parallel to the first plane.

A virtual object display device comprises a display and a display control device configured to perform display control of the display. The display control device includes: a coordinate system calculation unit configured to detect movement and rotation of the virtual object display device in a real world, and use an inertial coordinate system in which a coordinate origin thereof follows the movement of the virtual object display device and an effective field of view of the display is rotated therein in accordance with the rotation of the virtual object display device so as to define an arrangement position of an inertial coordinate system virtual object; and a display control unit configured to, when the inertial coordinate system virtual object is included in the effective field of view of the display, display the inertial coordinate system virtual object within the effective field of view.

A display control apparatus for controlling display of a display device acquires speech collected by a plurality of microphones and estimates a sound-arrival direction of the acquired speech. Then, the display control apparatus causes a text image corresponding to the acquired speech to be displayed in a predetermined text display area in a display unit of the display device, and causes a symbol image associated with the text image to be displayed at a display position in the display unit, the display position corresponding to the estimated sound-arrival direction.
