Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a front-mounted image display device such as a face mount display (FMD) and a head mount display (HMD), and an operating device.

[0002]

2. Description of the Related Art Opportunities for viewing, on a personal computer, moving image contents obtained by distribution on the Internet and moving image contents reproduced from various recording media such as DVDs are increasing. Then, it is possible to view such a moving image content on a front-eye mounted video display device such as an FMD or an HMD, rather than using the display of a personal computer.

[0003]

The display resolution of FMD, HMD, etc. depends on the number of pixels of the liquid crystal display panel used. At present, many FMDs and HMDs are used for viewing video images, and use inexpensive liquid crystal modules having a relatively low resolution. When the state of the screen of the personal computer is directly displayed on the FMD or the like, the FMD or the like having a high display resolution is required.
By using an FMD or the like having such a high display resolution, not only the reproduced video of the moving image content but also the list screen of the moving image file can be clearly displayed. Therefore, the user can operate the mouse while wearing the FMD etc. to search the video content, select the video content, start the video content playback software, operate the video content playback software, and so on, until the video content is played back. You can perform a series of operations in.

However, an FMD having a high display resolution is expensive. On the other hand, in the low-resolution FMD, the characters and fine display on the screen cannot be recognized because of the low resolution, and only the reproduced video of the moving image content can be seen. It is difficult to continue as it is, and there is dissatisfaction with the viewing operation of the video content.

It is an object of the present invention to provide an in-eye mounted image display device capable of operating the moving image content reproduction software from the in-eye mounted image display device side and an operating device capable of being operated on the operating device side. And

[0006]

In order to solve the above-mentioned problems, an in-eye mounted image display device according to the present invention is connected to an information processing device equipped with software for reproducing moving image contents. An operation switch, and an interface for giving a signal corresponding to a shortcut key set in the software to the information processing apparatus in response to operation of the operation switch,
It is characterized by having.

With the above configuration, the user can operate the moving image content reproduction software of the information processing device with the operation switch provided on the front-eye wearable image display device while wearing the front-eye wearable image display device. it can.

The operation switch may be arranged in the main body of the image display apparatus in front of the eye. Further, the operation switch may be arranged in a housing provided on a cord connected to the information processing device from the front-eye wearable image display device main body.

It is preferable that the interface section is provided in a housing different from the main body of the image display apparatus mounted in front of the eye so that the weight of the main body can be reduced and the burden of mounting can be reduced. it can.

The user can give a desired command to the moving image content reproduction software by recognizing and operating the arrangement of the operation switches, but the shapes of the operation switches are made different from each other so that the user can feel it by touch. Is even better.

Further, the operating device of the present invention is an operating device connected to an information processing device having software for reproducing moving image content, and the operating switch is operated by the software according to the operation of the operating switch. An interface for giving a signal corresponding to the set shortcut key to the information processing apparatus. It is preferable that the operation switches have different shapes so that they can be recognized by touch.
