Reference will now be made in detail to the present embodiments of the disclosure, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers are used in the drawings and the description to refer to the same or like parts. According to the embodiments, it will be apparent to those skilled in the art that various modifications and variations can be made to the structure of the disclosure without departing from the scope or spirit of the disclosure.
Reference is now made to
Therefore, with the structure described in the above embodiment, the user can adjust the optical assembly 300 to correspondingly align with the user's eye according to the position of the user's eye E so that the head-mounted display apparatus can provide images to the user, thus, the user will not feel uncomfortable during viewing, thereby increasing the willingness of the user to use the apparatus.
In this embodiment, the wearing apparatus 100 is used to be worn on a user's head. For example, the wearing apparatus 100 can be a visor cap that reveals the top of the user's head. However, the disclosure is not limited thereto. In other embodiments, the wearing device may be a baseball cap that hides the top of the user's head. Specifically, in the embodiment, the head-wearing portion 110, for example, is a strip body. The hat brim portion 120 includes a top portion 121 and a bottom portion 123 which are opposite to each other. The display screen 210 and the optical assembly 300 are commonly disposed on the bottom portion 123 of the hat brim portion 120.
The display screen 210 is equipped in the head-mounted display apparatus 10, and connected to an external computer (not shown in figures) via cables so as to be controlled by the external computer. Thus, the display surface 211 of the display screen 210 can provide images to the user's eye E through the optical assembly 300. The display screen 210 is, for example, a non-transmissive type display.
Furthermore, the head-mounted display apparatus 10 further includes a fixed frame 400. The fixed frame 400 is disposed on the bottom portion 123 of the hat brim portion 120. In the embodiment, the hat brim portion 120 is formed with an inner space 124. One part of the fixed frame 400 is received within the inner space 124, and other part of the fixed frame 400 extends outwards from the bottom portion 123 of the hat brim portion 120. For example, the fixed frame 400 includes a frame body 410, a separation plate 420 and a transparent area 430. The frame body 410 is fixedly disposed on a bottom portion 123 of the hat brim portion 120. The separation plate 420 is obliquely disposed on the frame body 410 so as to form an upper receiving portion 421 and a lower receiving portion 422 in the frame body 410, and the upper receiving portion 421 is located between the hat brim portion 120 and the separation plate 420. The display screen 210 is located in the upper receiving portion 421, disposed on the separation plate 420, and the display surface 211 of the display screen 210 exactly faces towards the transparent area 430. The lower receiving portion 422 is capable of receiving the optical assembly 300. The transparent area 430 is, for example, a through hole that penetrates through the separation plate 420, or a transparent acrylic sheet without through hole, connected to the upper receiving portion 421 and the lower receiving portion 422 for transmitting lights L of display surface 211 of the display screen 210 to the optical assembly 300 via the transparent area 430.
Also, the optical assembly 300 includes a loading frame 310 and a lens 320. The lens 320 is equipped in the loading frame 310. The loading frame 310 is disposed in the lower receiving portion 422, and is provided with a pivotal member 311 at the outer side of the loading frame 310. The frame body 410 of the fixed frame 400 is formed with a shaft-received hole 423 at an inner side of the frame body 410. The loading frame 310 is pivotally connected to the shaft-received hole 423 through the pivot member 311. Thus, the optical assembly 300 is rotatable relative to the fixed frame 400.
By rotating the optical assembly 300, the lens 320 of the optical assembly 300 can be adjusted at an angle relative to the user's eye E thereby properly directing the light L to the user's eye E.
In one embodiment, the lens 320 is, for example, a lens (e.g., a magnifying glass) for image enlargement, that is, the lens 320 can assist to provide magnifying images of the display screen 210 to the user's eye E. However, the disclosure is not limited thereto. In other embodiments, the lens 320 can also be a lens for providing upright virtual images, such as a convex lens, or the optical assembly can also be an optical assembly including a filter or other suitable one.
When the user prepares an external device D and slides the external device D into the upper receiving portion 421 through the opening 122, such that the screen S of the external device D exactly faces towards the optical assembly 300 in the lower receiving portion 422 through the transparent area 430. Thus, the images of the screen S of the external device D can be guided to the user's eye E through the optical assembly 300.
For example, the optical assembly 301 includes a loading frame 310 and a lens 320. The lens 320 is equipped in the loading frame 310. The loading frame 310 is disposed in the lower receiving portion 422, and is provided with a sliding block 312 at the outer side of the loading frame 310. The frame body 410 of the fixed frame 400 is formed with a sliding slot 424 at an inner side of the frame body 410. The loading frame 310 can be slidably engaged with the sliding slot 424 of the frame body 410 through the sliding block 312. Thus, the optical assembly 301 is slidable relative to the fixed frame 400. Therefore, by sliding the optical assembly 301 horizontally, the user can correspondingly adjust the gap distance between the optical assembly 301 and the user's eye E.
Although the disclosure has been described in considerable detail with reference to certain embodiments thereof, other embodiments are possible. Therefore, the spirit and scope of the appended claims should not be limited to the description of the embodiments contained herein.
It will be apparent to those skilled in the art that various modifications and variations can be made to the structure of the disclosure without departing from the scope or spirit of the disclosure. In view of the foregoing, it is intended that the disclosure cover modifications and variations of this disclosure provided they fall within the scope of the following claims and their equivalents.
