Definitions

  • the invention relates to an optical attachment for mobile display devices for virtual-reality- type reproduction of an audio-visual content played on the mobile display device, the attach- ment comprising an optical element transferring the image displayed on a display of the mobile device to the direct field of vision of a user, wherein the optical element is associated with at least a part of the display of the mobile display device on the one hand and with an eye of the user on the other.
  • Virtual reality viewers are increasingly widespread globally; in essence, they project the right and left sides of the image of the given mobile display device (e.g. mobile phone or tablet) to the right and the left eye, respectively, with the help of a pair of lenses of short focal length, creating thereby a sense of space in case of stereoscopic viewing on the one hand, and allowing wide-angle viewing due to the closeness of the sight on the other.
  • the given mobile display device e.g. mobile phone or tablet
  • the Present invention is based on the recognition that the structure of the virtual reality viewers is such that they can be of a small size and collapsible into plane format, and thus suitable for be- ing stored as part of a cover for the mobile device, resulting in more comfortable use by the user. Moreover, it has been realised that there is no need for excluding the ambient factors completely from the virtual reality viewer, so it is not absolutely necessary to shade the sides of the virtual reality viewer; consequently, the collapsible structure can occupy much less space and a manual control during operation also becomes feasible through the manually ac- cessible parts of the screen of the display device. Thus, it is an object of the present invention to provide an improved optical attachment showing said features that can universally used with different mobile display devices.
  • an optical attachment for mobile display devices for virtual-reality- type reproduction of audio-visual content played on the mobile display device comprising an optical element transferring the image displayed on a display of the mobile device to the direct field of vision of a user, wherein the optical element is associated with at least a part of the display of the mobile display device on the one hand and with an eye of the user on the other, wherein the optical element comprises two lenses arranged relative to each other at a distance adjusted to the eyes of the user, the lenses are arranged in a lens frame, the lens frame is movably connected to a support element holding the lens frame at a predetermined distance from display of the mobile display device, wherein the support element is foldably connected to the viewer device in the range of one edge of the mobile display device.
  • buffers keeping the lens frame in a plane parallel with the plane of display of mobile display device are formed on the support element, in the position of use of the optical attachment.
  • At least one spacer holding the lens frame in a plane parallel with, and at a predetermined distance from the plane of the display of the mobile display device is connected to the lens frame in the position of use of the optical attachment.
  • the support element is hingedly and foldably connected to the frame-like protective cover of the mobile display device.
  • the support element, the lens frame and the spacer are arranged jagging inward into the plane defined by the brim of the housing or protective cover of the mobile display device.
  • the support element, the lens frame comprising the optical element and the one or several spacer(s) unfolded into plane format forms a top covering sheet of the protective cover of the mobile device, protecting the display of the mobile display device.
  • a sharpness-adjusting lens is associated with at least one of the lenses of the optical element.
  • the lenses of the optical element are provided with an anti-reflective coating.
  • shading element elements at least restricting the incoming ambient light are associated with the lenses of the optical element.
  • the shading element elements are connected to the lens frame movably rela- tively to the plane of the lens frame.
  • the invention relates to a preferably collapsible virtual reality viewer optical attachment assignable to some portable or, with an equivalent term, mobile, viewer device, a tablet or a mobile phone; complementing its functionality; functioning as virtual reality viewer when used (in open position), held by the user to his eyes by hand, and collapsibly fitting to the external cover of the tablet or mobile phone in unused state, as its part or as screen pro- tector cover, as the case may be.

  • Figure 2 shows a perspective view of a possible embodiment of the optical attachment according to the invention in an operating, i.e. virtual reality viewing, open position;
  • Figure 3 shows the optical attachment according to Figure 2 in almost side view, before being closed from the open operating position
  • Figure 4 shows the optical attachment according to Figure 2 in closed, off, position

  • Figure 6 is the perspective view of another possible embodiment of the optical attachment according to the invention in an operating, i.e. virtual reality viewing, open position;
  • Figure 7 shows the optical attachment according to Figure 6 in closed, off, position
  • Figure 8 shows the optical attachment according to Figure 2, provided with optional shading elements.
  • FIG. 1 outlines a known scenario that is suitable for virtual reality viewing.
  • Display 2 is framed by a housing 3 of the display device 1.
  • One lens 5 of short focal length is fixed in some known way in front of each the symbolically represented eyes 4 of a user; the method of fixing is most frequently a stand-alone support structure of some kind in which the lenses 5 are arranged, or it may be spectacles worn by the user in the normal way.
  • the picture shown on display 2 is compiled into a virtually real picture 6 in the user's brain.
  • a support element 7 is fixed to a housing 3 of the display device 1 so that the support element 7 is fixed to one of the brims of display device 1 in a hingedly and foldable way.
  • This hinged connection can be created so that the support element 7 is made of the material of the housing 3 of the display device 1, integrally, and the connection between the brim of the housing 3 and the support element 7 is created through a weakening that provides for adequate mechanical stability.
  • the support element 7 can also be manufactured independent of the housing 3 and connected to the housing 3 through a hinge 8, maybe even detachably.
  • a shaped lens frame 9 is connected to the other end of the support element 7 .
  • the lens frame 9 connects to the support element 7 either through a weakening or, as in the example described here, through a hinge 10 and is dimensioned basically so that the lenses 5 arranged in it are at the empirically determined average distance from each other, so as to make the position of the optical axes of the lenses adequate for the highest possible number of users.
  • a cutting 11 is made on the lens frame 9 as shown in Figure 2, in the part between the lenses 5, to let the lens frame 9 be close enough to the eyes 4 of the user, that is, to prevent the lens frame 9 from bumping into the user's nose.
  • Lenses 5 are provided in a plane parallel with the plane of the display 2 and at a predetermined distance from the display 2 to obtain a sufficiently sharp and stereoscopic image when the picture being viewed on the display 2 is looked at through the lenses 5. To that end, it is to be ensured that the lens frame 9 be at the indicated predetermined distance from the display 2 during the use of the optical attachment. This can be ensured for example in the way shown in Figure 3, where two further spacers 12 are connected, also hingedly, to the lens frame 9.
  • spacers 12, unfolded from the plane of lens frame 9 abut with their other end on the display 2 of the display device 1, ensuring thereby that the lens frame 9 be at the predetermined distance from the display 2 at all times.
  • the material and the thickness dimension of spacers 12 is preferably adjusted to the similar corresponding parameters of the support element 7 and the lens frame 9.
  • buffers made of the material of support element 7 are formed on the support element 7 to ensure the right, preferably perpendicular, angle of the support element 7 unfolded from the housing 3 relative to the latter, and to secure the right, preferably also perpendicular, angle of the lens frame 9 relative to the support element 7.
  • These buffers may have the disadvantage of protruding from the receiving plane of display device 1 when the optical attachment is in idle state, hindering thereby the portability of display device 1.
  • the support element 7 of the optical attachment in its idle position can be folded back around hinge 10 to the back of the display device 1.
  • the lens frame 9 also smoothly covers the back 13, and the spacers 12 can also be folded onto the lens frame 9 so as to obtain the unused, closed, position shown in Figure 4, where the spacers 12 folded onto the lenses 5 fulfil also a lens protect- ing function. All things considered, this way the optical attachment only thickens the housing 3 of the display device 1 to an almost unnoticeable extent, and portability features of the display device 1 do not change significantly.
  • Figure 5 shows schematically the option that it is not absolutely necessary to split the entire display 2 of the display device 1 into a half left side part 2a and a half right side part 2b.
  • these areas 2c, 2d can also be made smaller than the size of the display 2, with the additional benefit that one or several control areas 14 can be formed on the display 2 (for a display 2 with a touch panel), that will offer a navigation option to the user also during the use of the optical attachment.
  • Figures 6 and 7 show a further possible embodiment of the optical attachment according to the invention in an open and in a closed position.
  • the support element 7 connects to the housing 3 through the hinge 8 formed on one of the longitudinal sides of the housing of display device 1, throughout the length of the brim of the housing 3, and the lens frame 9 comprising the lenses 5 has an identical longitudinal dimension with it.
  • the role of spacers 12 mentioned in the description of the previous embodiment is taken over by a further element, of the same size as the length of the support element 7 and of the lens frame 9, and its width dimension is such as to put the lens frame 9 of the optical attachment opened to operating position at the required distance from display 2 in the indicated way.
  • the right position of the lens frame 9 parallel with the display 2 is ensured by the width dimension and heeling angle of the support element 7. This design can be ensured by the proper choice of the width dimensions of support element, 7, lens frame 9 and spacer 12, respectively.
  • the optical attachment In open position, the optical attachment can be stabilised mechanically, manually, magnetically or by some other known mechanical arrangement.
  • This embodiment has the further advantage that it does not have to be folded back on the back 13 of the housing 3 of the display device 1 in idle state, but it can simply be closed, smoothly folded, on the display 2 of the display device 1, and it can be used as its protective cover.
  • the housing 3 of the display device 1, and in particular its hinge 10 holding brim can be designed so that the optical attachment would fold, in idle position, onto the display 2, so as to be in the same plane as the frame of the housing 3, without protruding from it, and without getting caught for example in other objects during the movement, carrying, of the display device 1.
  • Figure 6 shows symbolically a further possible embodiment where lenses 5 are not fixedly integrated into the lens frame 9 but they are inserted into mounting brackets 15 slidably in a direction parallel to the longitudinal axis of the display device 1.
  • This design makes it possible to slightly alter the optical axes of lenses 5 relative to each other, and the optical attachment can thus be set more precisely for its user ever to perceive the virtual reality picture 6 more per- fectly.
  • Lenses 5 can be made of glass or plastic and, similarly, the afore-mentioned elements of the optical attachment can also be made of plastic or metal, the last providing for more protection and a longer life span and more reliable operation.
  • hinge 8 connects to a U-shaped channel (not shown in the Figures), with the help of which the support element 7 can easily be clipped to or slid onto the housing 3 of the display device 1.
  • a hinge 8 may have a support element 7 comprising a permanent magnetic section, or the support ele- ment 7 can be clipped onto the housing 3 of the display device 1.
  • shading elements 16 are connected to the lens frame 9, for example as outlined in Figure 8, may be advantageous in particular in a light environment. Size and shape of the shading elements 16 is cho- sen, of course, so as to let the optical attachment fold smoothly on the display 2 of the display device 1 in unused state.
  • shading elements 16 are eye shades made of some elastic material, connected to the lenses 5, and due to their flexibility, they are also capable of folding smoothly onto the display 2.
  • One advantage of the invention is that, by providing for coilapsibiiity, the structure occupies very little space and it is essentially two-dimensional in closed position (i.e. it is a flat, plane structure), providing for easy packaging and transportation.
  • the invention has the further advantage that, due to its physical dimensions, it can be fixed to a mobile phone or a tablet; it does not disturb their use in closed position, so it enriches the basic functionality of the mobile phone or the tablet; virtual reality viewing with the help of the invention does not require special preparations, so utilisation frequency increases, and virtual reality can become a basic functionality.
  • a separate, typically 3D auxiliary frame is also needed besides the tablet or the mobile phone; the tablet or phone must be fixed on it causing inconveniency in many cases, thus, the viewer is often not promptly available.
  • Another advantage of the invention is that, due to easy usability, the tablet or mobile phone can be used basically simultaneously in a traditional way and as a virtual reality viewer, since the switch-over from one function to the other can be executed in a few seconds.
  • Another advantage of the invention is that, during utilisation, an interactive control option is provided by using the uncovered accessible touch screen surface, so this solution requires no special control device.
  • the invention can be used in many fields, from engineering design through therapy to education. It can be used well in any field where it is expedient to use the device as virtual reality viewer while retaining the traditional functionality of the tablet or mobile phone.
