Abstract: A head-mounted display comprises: a wearing body; a display; a communication module configured to perform communication connection with a mobile information terminal; a field of view(FOV) sensor configured to output status data used for determining whether the mobile information terminal is included in a user's FOV through the wearing body; and a controller connected to each of the display, the communication module, and the FOV detection sensor. The controller determines whether the mobile information terminal is included in the user's FOV based on the status data, and performs display control with respect to the display so as to display an application screen of the mobile information terminal on the display when determining that the mobile information terminal is not included in the FOV, and not to display the application screen on the display when determining that the mobile information terminal is included in the FOV.

Abstract: An HMD includes first and second batteries mounted therein, and includes a plurality of power receivers that receive power from the first and second batteries by wireless transmission, a power supply manager that monitors states of the first and second batteries, a communication interface that performs wireless communication with the first and second batteries, and a plurality of limiters that limit the power received by the plurality of power receivers. A controller causes the limiters to limit power, which is supplied to a load, according to a power use state of the load in the device, and the power supply manager acquires information of remaining power storage amounts of the first and second batteries through the communication interface and displays the acquired information on a display. Therefore, since it is possible to supply power required for driving the device while wearing the HMD, the HMD can be continuously used.

Abstract: The occlusion is faithfully expressed even in the binocular vision in the AR display by a head mounted display apparatus or the like. A head mounted display apparatus 10 includes a lens, a lens, a camera, a camera, and a control processor. A CG image for a right eye is displayed on the lens. A CG image for a left eye is displayed on the lens. The camera captures an image for the right eye. The camera captures an image for the left eye. The control processor generates the CG image for the right eye in which occlusion at the time of seeing by the right eye is expressed and the CG image for the left eye in which occlusion at the time of seeing by the left eye is expressed, based on the images captured by the cameras and projects the generated CG image for the right eye and CG image for the left eye onto the lenses and. A center of a lens of the camera is provided at the same position as a center of the lens. A center of a lens of the camera is provided at the same position as a center of the lens.

Abstract: An augmented reality (AR) display device includes a camera that captures a background image; a distance measuring sensor that measures a distance to a real object in the background image; a position and orientation sensor that detects the position of the camera and the shooting direction of the camera; a controller that recognizes the real object from the background image captured by the camera and associates the predetermined AR object with the recognized real object; a display displaying an image of the associated AR object; and a memory that stores data of the real object and the AR object associated with each other. The controller determines whether or not the real object is movable from the measurement result of the distance measuring sensor, and arranges the AR object according to the current position of the real object when the position of the real object associated with the AR object moves.

Abstract: There are provided a 3D AR content creation device, a 3D AR content playback device, and a 3D AR content creation system capable of performing 3D display in consideration of the depth relationship between a background image and a 3D AR object. For the purpose, the 3D AR content creation device includes a camera, a position information sensor that detects position information of the camera, and a controller. The controller measures depths of feature points of at least a part of a background image captured by the camera, gives position coordinates of a space corresponding to the background image to an AR object having the feature points of the background image and a 3D image from the position information of the camera and the measured depths of the feature points, and evaluates depths of the feature points of the background image and the AR object to obtain a composite image.
