Abstract: In a cooperative display system that connects a portable terminal and a head mounted display to display information in cooperation, the portable terminal displays information on a first display, and transmits at least a part of the information that is displayed to the head mounted display, and the head mounted display shares and displays the information transmitted from the portable terminal on a second display. Here, the information displayed on the portable terminal is hierarchical information, and the information displayed on the head mounted display is lower-level information in the hierarchical information. In addition, whether a user is stationary or moving is detected by a sensor of the portable terminal, and in a case where the user is stationary, the display of the information on the portable terminal is stopped, and the information is displayed only on the head mounted display.

Abstract: An HMD includes: a camera configured to image an external landscape; a camera abnormality detector configured to detect operation abnormality of the camera; a sensor group configured to detect a position, a distance, and the like of an object within the external landscape; a sensor abnormality detector configured to detect operation abnormality of the sensor group; an image generator configured to generate an image; and a mode switcher configured to switch a processing mode of the image generator. The image generator has an AR advanced processing mode of generating a high-accuracy AR advanced image by using image data captured by the camera and detection data detected by the sensor group, and an AR simple processing mode of generating AR simple image simpler than the AR advanced image. When an operation of the camera or the sensor group is abnormal, the mode switcher switches into the AR simple processing mode.

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: There are provided an HMD system capable of improving operability by realizing various input operations on a head mounted display (HMD), an HMD used therefor, and an operation method therefor. Therefore, in the HMD system, an HMD allowing an operation input from an external operation device is connected to a plurality of external operation devices. The external operation device is a device worn on the body of a user who uses the HMD, includes a sensor for detecting movement, and transmits operation information by moving the external operation device. The HMD includes a short-range wireless communication unit and an operation control unit. Operation information from the plurality of external operation devices is received through the short-range wireless communication unit. The operation control unit executes a predetermined operation based on the operation information received from the plurality of external operation devices.

Abstract: A modulator of a distance measuring sensor unit 102 has a photographing pattern that includes a plurality of patterns different from each other, and modulates intensity of light. A gesture detecting unit divides image data obtained by receiving light transmitted through the modulator by the image sensor; restores an image by calculation based on a developing pattern corresponding to the photographing pattern in a divided unit; and obtains an image for detecting gesture of a user. This makes it possible to obtain an image of an object in an outside world without using a lens for forming an image. Therefore, it is possible to reduce a load on a user when the user wears the apparatus.

Abstract: The MR display device includes a controller and a display unit. The controller recognizes a reality object from a reality video imaged by a camera and links a predetermined virtual object to the reality object based on an operation of an experiencing person. The display unit displays a video of the linked virtual object. The controller acquires a recognition result of a reality object generated by the other MR display device and data of the linked virtual object, via a communication unit, synthesizes the acquired data and the own data, and displays a video obtained by the synthesis on the display unit. In addition, the controller allows an edit of the virtual object linked to the reality object on the video displayed on the display unit, based on an operation of the experiencing person.
