Title: Three-dimensional image display glasses for smart device having touch function

Description:
TECHNICAL FIELD 
     The present invention relates to three-dimensional image display glasses for a smart device, and more particularly, to three-dimensional image display glasses for a smart device which have a touch function to indirectly touch and drag across a screen of a smart device by manipulating a touch button provided at an outer portion of the three-dimensional image display glasses, instead of directly touching the screen of the smart device installed in the three-dimensional image display glasses. 
     BACKGROUND ART 
     As interest in three-dimensional stereoscopic images and virtual reality has recently increased, a variety of devices, which enable a user to experience three-dimensional stereoscopic images and virtual reality through smart devices, have been developed. 
     In particular, three-dimensional image display glasses for a smart device that allow a smart device to be installed thereon and display a three-dimensional image through synthesis of left and right split images for 3D display to be displayed in a smart device have been developed and are commercially available. 
     However, these three-dimensional image display glasses are widely applied to applications for promotion of model houses and for gaining experience such as fire suppression experience. Accordingly, such three-dimensional image display glasses are provided to a variety of users for promotion and experience, are difficult to return, and are distributed to maximize promotion and experience. Thus, customers, who want to provide promotion and experience through three-dimensional image display glasses, require three-dimensional image display glasses with low manufacturing costs. 
       FIG. 1  is a perspective view illustrating a structure of general three-dimensional image display glasses for a smart device, which are used for distribution. The structure of the general three-dimensional image display glasses for a smart device will be described with reference to  FIG. 1 . The general three-dimensional image display glasses for a smart device include a main body  10 , a smart device fixing and mounting part  20 , and a smart device positioning part  30 . The main body  10  has a box shape with an opening at a front surface thereof, and includes a face contact part  13  having an oval shape that enables a user to position eyes thereof against a rear surface corresponding to the front surface and including lenses  40 - 1  and  40 - 2  to provide a 3D image through synthesis of images for 3D display, displayed on a screen of a smart device  100  placed in front of the glasses, to be viewed by a user. In addition, the main body  10  includes Velcro tapes  12 - 1  and  12 - 2  at a main body top part  11 . 
     The smart device  100  is positioned on the smart device positioning part  30  so that a screen thereof faces the front surface of the main body  10 . 
     The smart device fixing and mounting part  20  is configured such that, to fix the smart device  100  positioned on the smart device positioning part  30 , a front cover part  22  covers a rear surface (a surface opposite the screen) of the smart device  100  and a top cover part  21  extending perpendicular to the front cover part  22  is attached to a front portion of the main body top part  11 , thereby being coupled to the main body  10 . Velcro tapes  21 - 1  and  21 - 2  provided at opposite sides of the top cover part  21  of the smart device fixing and mounting part  20  are adhered to the Velcro tapes  12 - 1  and  12 - 2  of the main body top part  11  of the main body  10  so that the smart device fixing and mounting part  20  is attached to the main body top part  11 . The smart device  100  should be configured such that images for 3D display are being displayed before the smart device  100  is positioned on the smart device positioning part  30  or before the top cover part  21  of the smart device fixing and mounting part  20  is attached to the main body top part  11  of the main body  10 . 
     When the images for 3D display are being displayed on the smart device  100 , the smart device  100  is installed via the smart device fixing and mounting part  20 , and then a viewer positions a face thereof against the face contact part  13  such that eyes of the viewer can be placed on the two lenses  40 - 1  and  40 - 2  of the face contact part  13 , the viewer may view, as a three-dimensional image, the images for 3D display being displayed on the smart device  100  via the two lenses. 
     As described above, conventional three-dimensional image display glasses are produced for distribution. Thus, conventional three-dimensional image display glasses are used only for watching a simple 3D video, and thus a screen of a smart device cannot be touched, and, accordingly, it is impossible to control the functions of a smart device. Since the functions of a smart device cannot be controlled, as described above, images for 3D display have to be displayed before positioning the smart device  100  on the smart device positioning part  30 , resulting in user inconvenience. 
     In addition, in conventional three-dimensional image display glasses, to control the function of a smart device while a 3D image is displayed, a screen of the smart device  100  is clicked after the smart device fixing and mounting part  20  is detached from the top cover part  21 , and then the smart device fixing and mounting part  20  is attached to the top cover part  21 , or the screen of the smart device  100  should be touched with a finger via a gap between the glasses, resulting in high inconvenience. 
     To address these problems, three-dimensional image display glasses for a smart device in which a separate device is installed on a smart device to control functions of the smart device have been developed and are commercially available, but manufacturing costs are high and it is thus difficult to use such glasses for distribution.

     MODE 
     Hereinafter, the structure and operation of the three-dimensional image display glasses for a smart device which have a touch function according to the present invention will be described with reference to the accompanying drawings. 
       FIG. 2  is a view illustrating a structure of three-dimensional image display glasses for a smart device which have a touch function according to a first embodiment of the present invention.  FIG. 3  is a view illustrating a structure of three-dimensional image display glasses for a smart device which have a touch function according to a second embodiment of the present invention. In  FIGS. 2 and 3 , the same elements as those of  FIG. 1  denote the same reference numerals. Hereinafter, the structure and operation of the three-dimensional image display glasses according to the first and second embodiments will be described with reference to  FIGS. 2 and 3 . 
     Three-dimensional image display glasses  1  for a smart device which have a touch function according to the present invention include a main body  200 , a smart device fixing and mounting part  300 , and a smart device positioning part  400 . The main body  200  includes a main body top part  11 , a face contact part  13 , a left side surface portion  15 , a right side surface portion  16 , and a bottom surface portion  17 , and has a box shape with an opening at a front surface thereof. 
     As illustrated in  FIGS. 2 and 3 , rear ends of the main body top part  11  and the bottom surface portion  17  are portions into which a face of a viewer is inserted and have a curved shape. 
     The face contact part  13  may have a curved shape as in the first embodiment of  FIG. 2 , or have a rectangular shape as in the second embodiment of  FIG. 3 . 
     The face contact part  13  includes a nose insertion part  14  via which a nose is inserted, and a pair of lenses  40 - 1  and  40 - 2  inserted into portions corresponding to positions of eyes of a human to provide a 3D image through synthesis of images for 3D display being displayed on a screen of a smart device  100  positioned on the front surface of the main body to be viewed by a viewer. 
     The main body top part  11  includes one or more touch button insertion portions  110  positioned in the front thereof, a touch button  120  inserted into the one or more touch button insertion portions  110 , and a Velcro tape  12 . The size of the touch button insertion portions  110  may vary according to a method of fixing the touch button insertion portions  110 . For example, as illustrated in  FIGS. 2 and 3 , when a touch button  120 - 1  is inserted into a lower surface of the main body top part  11  of the main body  10 , it is required that only a touch electrode  113 , which will be described below, of the touch button  120 - 1  protrude outside, and thus the size of the touch button insertion portions  110  does not need to be large. In contrast, as illustrated in  FIG. 4 , when a touch button  120 - 2 , which will be described below, is hook-coupled to the inside of the touch button insertion portion  110  by a button hook shaft  112 , the size of the touch button insertion portion  110  has to be increased as in  FIGS. 2  and  3 . 
     As illustrated in  FIGS. 2 and 3 , the Velcro tape  12  may include two Velcro tapes on left and right sides or may also include a single Velcro tape at the center. 
     In addition, the touch button  120  may be provided in singular or plural at an arbitrary position in the front of the main body top part  11 . 
     The touch button  120  is configured such that an end of one side of the touch button  120  contacts the screen of the smart device  100  positioned on the smart device positioning part  400  and closely contacting an opening at the front surface of the main body  10  by the smart device fixing and mounting part  300 , and, as illustrated in  FIGS. 2 and 3 , an end of another side of the touch button  120  protrudes outside of the main body top part  11  and provides an effect as if, when a viewer touches the touch button  120  with a finger, the contact portion of the end of one side thereof is touched by static electricity of a human body. 
     Although  FIGS. 2 and 3  illustrate that the touch button  120  is provided on the left or right side of the main body top part  11 , the touch button  120  may also be positioned at the center or may be positioned only at the center according to the number of touch buttons. 
     The touch button  120  may also be configured on the left side surface portion  15  and the right side surface portion  16 . Detailed structure and operation of the touch button  120  will now be described in detail with reference to  FIGS. 5 and 6 . 
     However, touch buttons disposed on the left and right side surface portions  15  and  16  may be configured in a jog dial form including jog dial touch buttons  130 - 1  and  130 - 2  that provide an effect of dragging across a screen. The jog dial touch buttons  130 - 1  and  130 - 2  configured on the left and right side surface portions  15  and  16  provide an effect of dragging (touching) from up to down, or from down to up. 
     A jog dial touch button  130  may also be configured at the main body top part  11 , thereby providing an effect of dragging from left to right, or from right to left. Structure and operation of the jog dial touch button  130  will now be described in detail with reference to  FIG. 7 . The smart device positioning part  400 , on which the smart device  100  is positioned, extends from an edge of a lower end of the front surface of the main body  10  to correspond to the thickness of the smart device  100 . 
     The smart device fixing and mounting part  300  is configured in an integrated form perpendicular to the smart device positioning part  400  and includes the front cover part  22  to cover a rear surface of the smart device  100 , i.e., a battery cover part, and cover the front surface of the main body  10  and the top cover part  21  connected perpendicular to the front cover part  22  to cover a front portion of the main body top part  11  of the main body  10  and configured to be detached from the main body top part  11 . 
     The top cover part  21  may be provided, at a portion in which the touch button  120  is positioned, with a touch button insertion hole  310 , a touch button groove, or the like, through which the touch button  120  protruding outside of the main body top part  11  is exposed to the outside. Although not shown in the drawings, the touch button groove may have an uneven shape at an end portion of the top cover part  21 . 
     In addition, the top cover part  21  may include a Velcro tape as a detachable means, and, as illustrated in  FIGS. 2 and 3 , the Velcro tape may be disposed at a position that does not affect the touch button insertion hole  310 . 
     In the foregoing description, a case in which the top cover part  21  is configured to cover the front portion of the top part of the main body  10  has been described. However, the top cover part  21  may be connected to an end portion of the front surface of the main body  10  in an integrated form, or may not be configured as illustrated in  FIG. 4 , which will be described below. In the former, an opening may be formed in one or more sides of opposite side surfaces of the smart device positioning part  400  so that the smart device  100  can be inserted therethrough to be positioned on the smart device positioning part  400 . In the latter, an opening may be formed in a top portion of the smart device positioning part  400  so that the smart device  100  can be inserted therethrough and removed therefrom. 
     Although a case in which the smart device fixing and mounting part  300  is configured to cover the rear surface of the smart device  100  and the front portion of the main body top part  11  of the main body  10  has been described with reference to  FIGS. 2 and 3 , the smart device fixing and mounting part  300  may be configured as a holder to hold the smart device  100  in a state in which the smart device  10  positioned on the smart device positioning part  400  is placed on the front surface of the main body  10 , or the smart device fixing and mounting part  300  and the main body  10  may be configured in an integrated form, or the smart device  100  may be configured to be inserted into the smart device positioning part  400 . 
       FIG. 4  is a side view of the three-dimensional image display glasses for a smart device which have a touch function according to the first and second embodiments of the present invention.  FIG. 5  is a side view of three-dimensional image display glasses for a smart device which have a touch function according to a third embodiment of the present invention.  FIG. 6  illustrates a first example of a touch button structure of the three-dimensional image display glasses for a smart device which have a touch function according to the prevention.  FIG. 7  illustrates a second example of a touch button structure of the three-dimensional image display glasses for a smart device which have a touch function according to the prevention.  FIG. 8  illustrates a third example of a touch button structure of the three-dimensional image display glasses for a smart device which have a touch function according to the prevention.  FIG. 9  illustrates a fourth example of a touch button structure of the three-dimensional image display glasses for a smart device which have a touch function according to the prevention. Hereinafter, the above embodiments will be described with reference to  FIGS. 4 to 9 . The main body  10  according to the present invention may be made of paper, plastic, or the like having a constant thickness. 
     As described above, as illustrated in  FIG. 4 , the touch button  120  may be configured at the main body top part  11 , and the jog dial touch button  130  may be disposed at one or more of the left and right side surface portions  15  and  16 . 
     First, structure and operation of the touch button  120  will be described with reference to  FIG. 6 . As illustrated in  FIGS. 4 and 6 , the touch button  120  includes a “ ”-shaped button main body  111 , the touch electrode  113  protruding outside of the main body top part  11  so that a viewer can touch the touch electrode  113  with a finger, and a screen touch part  114  brought into contact with the screen of the smart device  100  fixed by the smart device fixing and mounting part  300 , and further includes the button hook shafts  112  protruding from opposite sides of the “ ”-shaped bent portion of the button main body  111  according to embodiment. The button main body  111  includes a first bar  1111  coupled in parallel to the main body top part  11  and a second bar  1112  coupled at 90 degrees or more with respect to the first bar  1111 . According to the first example, as illustrated in  FIG. 6 , the touch button  120  may include the first and second bars  1111  and  1112  configured in an integrated form. The button main body  111  may be made of a conductor and a semiconductor that allows static electricity formed in the human body to be transmitted to the screen (touch pad) of the smart device  100 , or a conductor or a semiconductor that connects the touch electrode  113  to the screen touch part  114  may be configured through the inside of the button main body  111 . However, for simplicity, the button main body  111  may be made of any one of a conductor and a semiconductor. The screen touch part  114  may be made of a silicon or the like similarly to a general stylus, or may be made of aluminum or the like. 
     As illustrated in  FIGS. 2 and 4 , the touch button  120  may be inserted into the touch button insertion part  110  of the main body top part  11  and fixed, or may be attached to a lower surface of the inside of the main body top part  11  and fixed. 
     In a case in which the touch button  120  is inserted into the touch button insertion part  110 , the button hook shafts  112  are hook-coupled to opposite sides of the inside of the touch button insertion part  110  and thus inserted into the touch button insertion part  110 . When the touch electrode  113  of the touch button  120  coupled in such a manner is touched by a viewer, the button main body  111  rotates about the button hook shaft  112  as an axis in a direction in which touch force is transmitted, and thus the screen touch part  114  may more strongly contact the screen of the smart device  100 . 
     In addition, the touch button  120  may be attached and fixed to the lower surface of the main body top part  11 . In this case, as shown in the insertion structure of the touch button  120 - 1  of  FIGS. 2 and 3 , the touch button insertion part  110  may be formed only to a size corresponding to the touch electrode  113 . 
     The touch button  120  according to the second example may include the first and second bars  1111  and  1112  configured in a separate form not in an integrated form such that the first and second bars  1111  and  1112  are hinge-coupled by a hinge  115 , and further include an elastic member  116  at a lower surface of the first bar  1111  and a rear surface of the second bar  1112 , on which the screen touch part  114  is configured. Since the first bar  1111  is fixed to the main body top part  11 , the elastic member  116  pushes the second bar  1112  in a direction in which the smart device  100  is positioned, and, accordingly, the screen touch part  114  may strongly contact the screen of the smart device  100 . Since the screen touch part  114  strongly contacts the screen of the smart device  100 , touch performance may be enhanced. The first bar  1111 , the hinge  115 , and the second bar  1112  may also be made of any one of a conductor and a semiconductor that allows static electricity of the human body to be transmitted to the screen of the smart device  100 , or separate conductor and semiconductor that connect the touch electrode  113  to the screen touch part  114  may be connected through the inside of the touch button  120 . 
     In addition, as illustrated in  FIG. 4 , in a case in which an opening is formed in a top portion of the smart device positioning part  400 , when the smart device  100  is inserted into the smart device positioning part  400 , the touch button  120  has to be configured such that the screen touch part  114  can be touched. In this case, the touch button  120  may be configured as illustrated in  FIG. 8 . The touch button  120  of  FIG. 8  may include the button main body  111  and an electrode part  140  adhered along an outer side of the button main body  111 . The electrode part  140  may be made of aluminum or the like. The electrode part  140  may have the same width as that of the button main body  111 , or may have a smaller width than that of the button main body  111 . 
     In such configuration illustrated in  FIG. 8 , as illustrated in  FIG. 4 , the touch button  120  may be configured in the touch button insertion part  110  of the main body top part  11  such that the electrode part  140  attached to the second bar  1111  of the button main body  111  protrudes farther than an end portion of the front surface of the main body top part  11  of the main body  200 . In this case, the touch button insertion part  110  may have an opening at a front surface thereof. 
     In a case in which the smart device  100  is inserted into the smart device positioning part  400 , the structure of the jog dial touch button  130  according to the fourth example will now be described with reference to  FIG. 9 . The jog dial touch button  130  includes a rotary shaft  131  arranged in parallel to the screen of the smart device  100 , a drag/touch part  133  coupled in perpendicular to the rotary shaft  131  and configured to touch and drag the screen of the smart device  100 , and a jog dial  132  connected to one end of the rotary shaft  131  and protruding from the left and right side surface portions  15  and  16  of the main body  200  as illustrated in  FIGS. 2 and 3  to be rotatable by a viewer. When the viewer rotates the jog dial  132 , the drag/touch part  133  touches the screen of the smart device  100  while moving from up to down, or from down to up according to the direction of rotation, whereby an effect of dragging from up to down or from down to up may be provided. The rotary shaft  131 , the jog dial  132 , and the drag/touch part  133  may be made of any one of a conductor and a semiconductor that allows static electricity of the human body to reach the screen of the smart device  100 . The drag/touch part  133  may be formed of general silicon to prevent the screen of the smart device  100  from being scratched. 
     Meanwhile, it will be easily understood by those of ordinary skill in the art that the present invention is not limited to the aforementioned typical exemplary embodiments and various modifications, changes, substitutions, or additions may be made without departing from the essence of the present invention. These modifications, changes, substitutions, or additions should be construed as being within the spirit of the present invention as long as they are within the scope of the appended following claims. 
     INDUSTRIAL APPLICABILITY 
     Three-dimensional image display glasses for a smart device which have a touch function include a touch button having one side brought into contact with a screen of a smart device and another side formed on an external portion of the three-dimensional image display glasses to be touched by a user, and thus an effect of touching the screen of the smart device may be obtained by simply touching a touch switch configured on an external portion of the three-dimensional image display glasses. In addition, the three-dimensional image display glasses include a jog dial touch button, and thus a drag/touch function may be used only by manipulation of a jog dial touch button without directly dragging across the screen of the smart device with a finger and, accordingly, an effect of controlling various functions may be obtained. Thus, the present invention is very useful and also highly industrially applicable.
