Description

[0001] The invention relates to a display device with a device for the virtual display of image information for a user.

[0002] DE 1 715 730 U describes a device for moving one or more scale pointers for optical pantographs with a scale mounted below the drawing plane, wherein the bands moving the scale pointer run over one or more deflection rollers.

[0003] Furthermore, DE 1 706 356 U discloses an optical pantograph by which sections (25 × 25 cm) from transparent materials can be enlarged to any desired scale.

[0004] Furthermore, DE 959 411 B discloses an optical pantograph with a template wall movable in its own plane in all directions, wherein the template wall is adjustable by means of shafts and its actuating elements are located in such close proximity to the drawing surface that they can be operated from the front by the person drawing.

[0005] Furthermore, CH 689 904 A5 discloses an electro-optical apparatus for producing an image of a real scene, which is characterized by the fact that the image is arranged with respect to the scene in such a way that the directions up, down, left and right in the image correspond directly to the directions up, down, left and right of the scene and the normal direction of the image plane is directed towards the center of the scene and the said image contains information retrieved from a data storage device, the information of which is assigned to the position and orientation of the apparatus.

[0006] Furthermore, US 2013 / 0293447A1 describes a head-mounted display system comprising a frame that can be attached to the head of an observer, one or two eye-defined display positions positioned in front of the respective eye of the observer, a display element attached to one or two eye-defined display positions, such a display element providing a virtual image of a video display by means of a video signal from a video signal source in front of the respective eye of the observer, a motion sensor that detects the movement of the observer's head, a high-pass filter that generates a high-frequency component and a low-frequency component of the dictated movement according to a threshold frequency, and a control unit.which, depending on the movement of the observer's head as described above, moves the displayed image in the opposite direction. US 2018 / 0190031A1 discloses a portable device for displaying a "mixed reality" image, which enables the simultaneous viewing of VR or AR images and scenes from the real environment.

[0007] The object underlying the invention is the virtual representation of image information, which is solved by a device according to claim 1, wherein claims 2 to 15 are advantageous embodiments of the invention.

[0008] According to claim 1, the invention relates to a display device with a device for the virtual display of image information. Image information is displayed to the user's first eye via an optical unit, while simultaneously the user's second eye is directed at a more distant surface. This optical unit, preferably designed as described below, is itself held on the more distant surface by means of a movable mount, such as a scissor or gooseneck mechanism, and aligned relative to it. Thus, a desired distance between the second eye, which looks freely at a surface, and the distance between the first eye and the optical unit can be individually adjusted for each user.

[0009] In principle, the invention includes the possibility that the optical unit is arranged, for example, on the user's head via a head mount without a mechanical connection to the surface for the other eye, or that the optical unit is held freely with one hand by the user. However, in this case, the user must maintain the correct distances from the first eye to the optical unit and from the second eye to the surface, which requires considerable practice and, for example, a steady hand. In principle, a rigid mount is also possible.

[0010] Due to the physiology of vision or visual perception, the brain automatically and virtually projects the image presented to the user by their first eye, on which that eye is focused, onto a more distant surface. The second eye then focuses on this distant surface to clearly see the projection, which occurs only in the brain during visual perception. The user can then use one or both hands and appropriate drawing or painting tools, such as brushes, pencils, and the like, to trace or embellish this projected image on the distant surface.

[0011] This virtual projection is caused by the fact that the visual information from each eye is only sent to one hemisphere of the brain, but the hemispheres are connected to each other via a nerve tract called the corpus callosum. Therefore, the brain assumes that it should actually be seeing the same thing with both eyes, and the visual information for the other eye is mentally projected onto the empty space.

[0012] It is understood that the entire display device, comprising the optical unit, the movable mount, and the distant surface, is designed such that the optical unit can be positioned in front of either the left or right eye, according to the user's preference, so that the other eye—the right or left—can then view the distant, essentially blank surface. This also depends on whether the user is right- or left-handed and which eye is dominant when drawing or painting. Therefore, the terms "left eye" and "right eye" are interchangeable.

[0013] The surface onto which the user projects the virtual image in their brain can be designed in any way they like, for example, as a white plastic sheet, canvas, or similar material. Likewise, sheets of paper, cardboard, fabric, or canvases can be stretched on or around this surface for painting, decorating, and the like.

[0014] The system thus utilizes the interaction of the right and left hemispheres of the brain, which are connected by a nerve tract called the corpus callosum, to present visual information exclusively to one eye, specifically the left eye, of a user. This information is not correlated with the perception of the other eye, specifically the right eye. Based on the experience that both forward-facing eyes generally see and complement the same visual information, this data exchange between the left and right hemispheres allows the user to project the visual information perceived by one eye, specifically the left eye, onto a surface, specifically a screen, presented to the other eye, specifically the right eye. This projection occurs without the visual information actually being present on the screen, thus making the existing surface, specifically the screen, usable.to manually reproduce the projected image information and opens up the possibility of distorting and / or supplementing the image information that can be reproduced on the surface, especially on a canvas, by the user, so that an individual work can be produced using drawing methods based on the image information offered to one eye, especially the left eye.

[0015] The device comprises one or more combinable lenses, which preferably enable the magnification or reduction of the projected image information. Thus, depending on the magnification or reduction achieved by the lens and the user's distance from the device, the optimal size of the projected image information can be adjusted. The lenses may be diverging and / or converging lenses, or other optical elements such as apertures or similar devices may be used for focusing.

[0016] Preferably, the optical unit of the device is designed such that one or more of the optical elements it contains, such as lenses, magnifying glasses, apertures, or the like, can be pivoted into and out of a beam path. Thus, for example, pivoting one or more additional magnifying-like lenses into the beam path can increase the magnification factor as desired, while pivoting them out can decrease it. This also allows different formats of a template to be enlarged or adapted as desired, for example, to be viewed by a user across a surface. It is understood that the pivoting in and out of an optical element can be achieved either around a rotational axis or by a linear translational movement.

[0017] According to a further development, the invention provides for the device that the accommodation, i.e. the dynamic adjustment of the refractive power of an eye, can be adjusted by means of a lens so that the image information offered to one eye is perceived as sharp by the user.

[0018] Furthermore, in an advantageous embodiment, the invention provides that the at least one lens for accommodation is equipped with an adjustment mechanism, in particular a helical gear, so that the accommodation can be adapted to the respective visual acuity of a user.

[0019] According to a further development of the invention, the size of the projected image information can be adjusted to the available surface, particularly a screen, by changing the user's distance from the surface. The distance between the image information and the eye viewing the image information is always smaller than the distance between the projecting eye and the surface, especially the screen. Thus, the user can adjust the size of the projected image information to their own preferences or the available surface.

[0020] In a further advantageous embodiment, the image information can be displayed using a 2D image or a display, in particular a smartphone display. Thus, virtually all available media, especially from the internet, are available as image information.

[0021] Furthermore, the device includes a holder for receiving image information; in particular a 2D image or a display, especially a smartphone display, which is associated with the device or the optical unit. The holder allows, for example, a smartphone to be positioned on the optical unit in such a way that the image on the smartphone's display is sharply visible to the user, or to one of their eyes, via the lenses in the optical unit.

[0022] The invention also provides for the device to have a light source, in particular an LED lamp, so that optimal illumination of the image information offered to one eye by the device is ensured, regardless of the surrounding light conditions.

[0023] According to another embodiment, a cushion is provided for one eye, which lies flush against the eye area. The outer part of this cushion is preferably made of soft material, in particular leather, and the inner part of foam, in particular polyurethane foam. This prevents any potentially disturbing stimuli from reaching the eye facing the image information. Wearing comfort is also increased. It is understood that the cushion can be designed for the right or left eye and is preferably interchangeable.

[0024] In one embodiment, the movable bracket, which positions the device in front of the eye, can be controlled, for example, by an electric motor. This allows the device to be aligned to different positions relative to the surface, in particular a screen.

[0025] In a further advantageous embodiment, the invention provides that the device includes a clamping device, in particular clamping jaws. Thus, the device can be clamped, for example, at any point on the surface, on a stand for the surface, or on a table edge, depending on the desired orientation of the device relative to the surface. Alternatively, other mechanically releasable fastening means can be provided instead of clamping jaws. With such a clamping device, the device can also be attached, for example, to an existing lamp, such as a desk lamp. Thus, no additional movable support is necessary, and the surface can already be illuminated with an existing desk lamp.

[0026] Furthermore, in an alternative embodiment, the invention provides that a selfie stick with a smartphone holder can be used as a holder for the device.

[0027] In a further advantageous embodiment, the device includes a head mount, which allows the device to be preferably positioned on the head in front of one eye, either the left or right eye, according to the user's preference. This design thus offers the user maximum flexibility.

[0028] According to a further embodiment, the invention provides that the device can be used for training eye functions, in particular accommodation and binocular vision.

[0029] Furthermore, in an advantageous embodiment, the device is constructed from metal and / or plastic and / or natural material, in particular wood, natural rubber and rubber, so that the optimal properties, in particular stability and weight, can be adapted depending on the application and design.
