A head mounted display for supporting improvement in an act of moving a body is provided. The head mounted display includes image display unit that transmits external scenery therethrough and forms an image, a body motion detection unit that detects motions of a body of a user and at least a part of a tool bundled with the body, a model moving image acquisition unit that accesses a model moving image storage unit which stores, as a model moving image, a moving image showing a motion of the body, used as a reference of the act and stores the model moving image for each type of act, and acquires one or a plurality of model moving images corresponding to a detection result from the body motion detection unit, and a display control unit that causes the image display unit to form the acquired model moving image.

Head mounted display, detection device, control method for head mounted display, and computer program

A head mounted display device that allows a user to visually recognize a content as a virtual image, includes a display part that displays the content in a predetermined display area, and a control part that determines a background color of the content and use environment brightness and adjusts brightness of the display area in response to the determination results thereof.

Network system

An order management system enables a customer to use a terminal device to order food, but can respond rapidly to changes and additions to the menu. When this system starts up, it transmits an operating program and image data from main management equipment to each of a number of order-taking terminal devices. Each order-taking terminal device stores the thus received operating program and image data and displays a menu screen on a display screen on the basis of the thus stored operating program and image data.

The order-taking terminal device stores the thus received operating program and image data and displays a menu screen on a display screen on the basis of the thus stored operating program and image data.

Terminal device

A projection type display system having an optical modulation unit which modulates light from a light source in response to preselected video signal data, a projection lens system for projecting the modulated light onto a display screen, and a focal adjustment device which is configured to alter the focal state of a resulting image which is focused onto the screen. The focal state is adjusted by translating the relative position of one or more lenses in the projection lens system with respect to the screen. The focal adjustment device further incorporates a range finding unit which determines the distance between the projection lens system and the targeted display screen, typically using a beam of invisible light, and an automatic adjustment element which adjusts the focal point of the projection lens system to optimally match the determined distance.

A video display for a liquid crystal display and a method for displaying a complex video signal thereon is provided. A line memory stores one line of video data of a complex video signal. A field memory stores one field of video data of the complex video signal. A signal driving circuit generates a signal driving signal in response to the video data stored in the line memory and the field memory. A multiplexer selectively transmits the video date from the line memory and field memory to the signal driving circuit. One horizontal period of the video signal is sequentially written in the line memory. During the first half of the horizontal period of the video signal, video data of the previous field which is stored in the field memory is transferred to the signal driving circuit. During the second half of the horizontal period, the video data stored in the line memory is transferred to the signal driving circuit. The signal driving circuit generates scanning driving signals for the liquid crystal display, each signal being divided into an odd and even field.
