Description

1247231 V. Description of the Invention (1) Technical Field of the Invention The present invention relates to a head-mounted system and a device for adjusting the focal length of a keyboard of a device, and the present invention also provides a finger positioning device for key input. Action key test T through a [prior art] in the U.S. patent, the display device, to transmit a generated image 95" "proposed-head-mounted image combined with the external image; the production part is to fix the optical element in the The eve type 2 display device includes a housing escaping an image generator to provide a high erection and at least two cover occlusion units or an action squeezing image, the device further comprising a permeable type The lens is converted into a display 3|H, set to 'and the display screen can be mounted from the device to the device; the = can be converted in the f direction; the uniform glasses; and can still be allowed The user can use the transmission MD alone (for example, the power MD is separated), so that η is in the US Patent 6, β 1 丄, q =. The display system, the system includes _ 5 also proposed a wearable way Processed signal And the wearable: no panel to display a signal output from the display panel according to a predetermined one, and a display system includes a grating, so that a magnifying lens is placed to pass the guide to guide the letter via the grating. The signal is displayed to the user's eyes, and the signal is amplified by 1 degree, and the slope is guided. The light is formed according to the wearable display system ^^~ or a plurality of substrates> V can be adjusted and installed Waveguide 1223731 V. DESCRIPTION OF THE INVENTION (2) In order to meet the specifications and apply the least amount of time in the U.S. patent image display system, the large-light device is first enlarged into the plane of the large optical device domain, so that the light is made of components. a magnified surface with a corresponding transmissive surface, and a plurality of magnified virtual images are displayed in the U.S. system, and the display device is connected to the display casing portion so that the display of the display element is at least reversed. Reflecting/the virtual image, the reflection is reversed by the second image, and is viewed by the viewing system of the patent system; therefore, the first release of a delicate virtual surface and a reflective display a field of view/penetration surface provided in a region of the first venting surface, a first amplification target light, such as the reflection/light-through device in the large-light device; and a synthetic amplification of the large-light device The system has proposed three transparent surfaces, which show that the reflection of the light-emitting device is reflected to the source and is embedded in the display, and the input surface and the reflection/wearing second amplification device amplify the light. The device is further customized and the endeavor is made to manufacture the head 5,9 9 1,0 including a microdisplay display surface, such that the portion is enlarged on the radiation/penetration surface / Penetrate into the wear / shoot the amplified light to install the one. The light projects a second reflection of the second surface, and the second surface of the virtual surface of the object surface is opposite to the large angle of the received light of the source source, and the image of the guided image is transmitted back to the first incident angle. Amplifying the first image of the virtual image, and displaying the video to the viewer, using '683' 584. A camera has been proposed to display a matrix display element mounted on a housing portion to correspond to the user. At least one eye. The display or image sensor allows the user to see the information or image, and the display can be mounted to the outside to move the display ’ so that the display is hovering

Page 8 1247231 V. INSTRUCTIONS (3) Inside or outside the user's field of view. A single eye type head mounted display device has been proposed in U.S. Patent No. 6,6,8,8,2, which is quite elegant and suitable for the user to include a viewer and an elastic member; the viewer includes a L CD, a main cymbal, a through lens, a frame, and a microphone.
