DETAILED DESCRIPTION OF THE INVENTION

(8) Exemplary embodiments of the present invention will be described below in detail with reference to the accompanying drawings. Wherever possible, the same reference numerals will be used to refer to the same elements throughout the specification, and a duplicated description thereof will be omitted. It will be understood that although the terms first, second, etc. are used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another element.

(9) As shown in FIG. 1A, the left and right supporting boards 2, 2a are supported by a hinge so as to be folded left and rightward by 90 based on a board 1 and the left and right fixing bars 3, 3a for fixing and separating a smart phone are provided on a rear surface of the left and right supporting boards 2, 2a.

(10) The left and right lens plates 6,6a are provided on the rear end of the board 1 as in FIG. 1(a) and FIG. 1(b) to be folded left and rightward by 90 based on the hinge 5 of the board 1 and the left and right lens 7,7a are provided on the left and right lens plates 6,6a, respectively. Here, the length of the board 1 is configured to be identical to the focal distances of the left and right lens 7,7a such that the focal distances of the left and right lens to reach on the surface of smart phone 200 that is mounted on the left and right fixing bars 3, 3a.

(11) According to the portable virtual reality device of the present invention, as shown in FIG. 2, the left and right supporting boards 2, 2a are deployed and the smart phones are mounted on the left and right fixing bars 3, 3a provided on a rear surface of the left and right supporting boards 2, 2a, and the left and right lens plate 6, 6a on a rear surface of the board 1 are deployed and the smart phones 200 and the left and right lens 7, 7a are arranged to be in parallel such that the focal distances of the left and right lens 7, 7a are adjusted automatically to the surfaces of the smart phones 200.

(12) That is, the board 1 is disposed at a center and the length of the board is formed to correspond to the focal distances of the left and right lens 7, 7a such that the focal distances are adjusted automatically.

(13) The reason that the board 1 is disposed at the centers of the left and right supporting boards 2, 2a and the left and right lens plates 6, 6a is because the left and right image of a smart phone correspond to an optical axis of the left and right lens 7, 7a such that a viewer views one 3D image.

(14) Further, the board 1 is disposed at the centers of the left and right supporting boards 2, 2a and the left and right lens plates 6, 6a so that a boundary between the left and right images of a smart phone is blocked by the board 1, thereby avoiding plural images which are viewed as 2-3 images in accordance with view angles.

(15) Meanwhile, since the left and right supporting boards 2, 2a is configured such that the surface of the smart phone is exposed, as shown in FIG. 2, a user can operate, change and drive a program while he/she views the images on the smart phone.

(16) The portable virtual reality device of the present invention may be folded to form a thin structure after using it as shown in FIG. 1B such that the left and right supporting boards 2, 2a are folded and then the left and right lens plates 6, 6a are folded, as shown in FIG. 1A and FIG. 1B.

(17) Assuming that a focal distance of a magnifying lens is 6 cm, it showed from experiments that the volume of the portable virtual reality device using the same lens when it is folded is expressed by 7 cm4 cm1.5 cm as widthlengththickness to form a thin film of 42 cm.sup.3, as shown in FIG. 1B. However, the volume of the conventional device, as shown in FIG. 5, reached to 2,040 cm.sup.3 by 12 cm17 cm10 cm as widthlengththickness.

(18) That is, the volume of the portable virtual reality device of the present invention is reduced remarkably to the volume 1/40 times as the volume of the conventional virtual reality device shown in FIG. 5.

(19) The weight of the portable virtual reality device of the present invention also is reduced noticeably to 60 g by more than times as the weight of the conventional virtual reality device of 400 g.

(20) Referring to the using method of the portable virtual reality device of the present invention, as shown in FIG. 2, the surface of the smart phone 200 is exposed inside the left and right supporting boards 2, 2a.

(21) Accordingly, according to the portable virtual reality device of the present invention, the surface of the smart phone is controlled frequently such that a user may change pictures, programs and operating the pictures while he/she views VR pictures, differently from the conventional VR device shown in FIG. 5, in which the smart phone is separated to control the smart phone screen separately, and then the smart phone is again mounted.

(22) Meanwhile, according to the present invention, an outer structure of the left and right supporting boards 2, 2a may be configured as a case type 300 as shown in FIG. 3, and when the main device 100 is embedded inside the case 300 when it is folded and carried, and the case 300 is deployed and the left and right supporting boards 2, 2a are deployed when it intends to use it.

(23) Further, according to the present invention, the left and right fixing bars 3, 3a may be configured as the cases that are separated to the left and right parts, or as various disclosed structure proper for mounting the smart phone.

(24) In addition, if necessary, a separate band may be provided on the board 1 or the left and right supporting boards 2, 2a to be arranged on a head of a user. In this case, the weight of the portable virtual reality device is light and thus it can be used for a long time. Accordingly, the portable virtual reality device of the present invention can be carried on a pocket since it can be folded to form a thin film.

(25) Meanwhile, various disclosed hinges including a hinge that is deployed and fixed may be used for the hinges 4, 5.

(26) Accordingly, when the portable virtual reality device of the present invention is used, the focal points of the pictures are corresponded, the smart phone 100 is mounted and separated simply, and it can be folded as a thin film thereby to reduce the volume and weight to be carried conveniently.

(27) Further, the portable virtual reality device of the present invention can be used simply and the manufacturing cost is low, and a user can control the picture of a smart phone while viewing the picture.

(28) While the invention has been shown and described with reference to exemplary embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. Therefore, the scope of the invention is defined not by the detailed description of the invention but by the appended claims, and all differences within the scope will be construed as being included in the present invention.
