Description

 Three-dimensional display system

 The present invention relates to a three-dimensional display, and is not limited to a three-dimensional display that allows user interaction.

 Background technique

 Three-dimensional display systems are well known and fall into a variety of technical categories. The stereo system relies on displaying two different images to the viewer's eyes. This can be achieved by projecting two images onto the same screen and providing the viewer with polarized glasses or glasses with color filters, so that the first image can only be seen by the viewer's right eye, while the second image can only be seen Seen for the viewer's left eye. There is also a naked eye stereoscopic system that does not require glasses, which respectively displays a separated image to each eye through a parallax barrier or a lenticular lens array.

 In a stereoscopic system, the images displayed to the left and right eyes of the viewer are the same image regardless of the position of the viewer relative to the image. Therefore, the viewer cannot see the side or the back of the image, but simply displays a single perspective with parallax. Eye tracking devices have been used to follow the user's gaze and to adjust the image in real time. However, these systems are only suitable for viewing by a single audience.

 Body three-dimensional displays are also known in the art and include "body scanning" devices. Such displays quickly project a three-dimensional image slice onto a moving two-dimensional surface, relying on persistence of vision to display a three-dimensional image to the viewer. However, since the display body in such devices must contain a mechanical part that moves quickly, it is impossible to use the volume scanning display as an interactive device since it is impossible to touch the image without causing damage. These displays are also not suitable for use in mobile devices such as laptops, tablets and mobile phones.

 "Static body" devices are also known techniques that avoid the use of moving parts in the display body. An example static body display device concentrates the laser light into the air at a point where it ionizes the air to form a plasma ball. Such a display does not require a moving portion in the display body, but the displayed image is composed of relatively large pixels, so the display resolution is low. Such displays are also limited to a single color or a small number of colors.

 Three-dimensional images can also be produced by holography. However, known holographic displays do not provide user interaction.

Existing fog, air, and water screens are transmissive screens, where the camera and viewer are on the screen. On both sides, separated by a screen. When the projector throws an image onto the screen, these screens scatter the light of the image so that the viewer can see the image at different locations. However, such screens cannot display three-dimensional images.

 Many of the above-described types of three-dimensional displays produce virtual images or are limited to images inside the display. In contrast to reality, virtual images cannot be wormed and therefore cannot interact with the user.

 It is an object of the present invention to provide a three dimensional interactive display that reduces or substantially avoids the above problems.

 Summary of the invention

 According to a first aspect of the invention, a three-dimensional display system includes a display housing, a medium that scatters light, and a plurality of projectors for projecting a two-dimensional image into or onto the medium, each image The instrument has means for adjusting the distance from the projector to the projection image, and each projector is pivotally mounted to the display housing to adjust the horizontal and vertical position of the projected two-dimensional image relative to the projector.

 This medium can scatter the light that is put into it, or scatter or diffuse the light that is applied to the surface of the medium, such as a fog screen, an air screen, 7}: the screen can be projected onto the surface of the screen. The light of the image is scattered or diffusely transmitted, thereby expanding the visible area of the image. The medium can also be solid or otherwise, not limited to gases and liquids. The first aspect of the invention comprises three preferred examples: a three-dimensional interactive display with a transmissive fog screen array, a three-dimensional interactive display with a reflective fog screen array, and a combination of a fog screen array and a three-dimensional interactive display. A shape design.

 By using a plurality of projectors, it is possible to form a three-dimensional image from a plurality of two-dimensional image components. This provides a three-dimensional image that can be viewed from many angles like a real object. Since each image component has a small field of view, a method of constructing a three-dimensional image by combining small image components has a great advantage, and a small field of view will minimize aberrations.

 Ideally, small image components will be merged together to form a single three-dimensional image. However, even when the two-dimensional image is slightly separated, it is possible to obtain a three-dimensional effect that is noticed by the eye, and sometimes a plurality of disjoint three-dimensional images may be formed.

 The position of each 2D image component can be adjusted by a projector that can adjust the projection direction and pivot the instrument in the housing. It is therefore possible to display many different three-dimensional images and to form moving images. There is no moving part in the display, so the projected image can be safely touched. The image can be high resolution and multi-colored, and no special equipment is required to view the image. Multiple viewers can view the display at the same time.

Each instrument includes a light source, a display screen, and a zoom lens. Each projector also includes wavefront modulation Device. Since the space can be substantially saved compared to the conventional mechanical zoom lens and the time required to change the focal length is reduced, the efficiency is improved. A projector having a light source, a display screen, and a zoom lens operates in a conventional manner to project an image onto a display screen, converges to a point determined by adjustment of the zoom lens and the modulator provided there.

 The zoom lens can be a liquid zoom invitation. Since the conventional mechanical zoom lens can save substantially space, the liquid zoom is particularly suitable for use in mobile display devices.

 Each step of bulging includes a swelled outer casing that is in the shape of a rectangular prism. This shape is beneficial because many of these projectors are effectively mounted to the frame.

 Each i-mirror optionally includes a conical frustum-shaped outer casing with the display screen placed near the narrow end of the outer casing and the zoom lens placed near the wide end. This shape is advantageous because the outer wall absorbs the least amount of light, enabling efficient operation.

 At least one camera is provided that is connected to a computer having image processing software. The camera is mounted to the display body of the display device to detect the presence and location of the real object associated with the projected image.

 When a camera and computer are provided, digital or other symbols form part of each projected two-dimensional image component, and the image processing software is configured to detect the presence or absence of a number or from a video signal or a plurality of video signals of the camera or cameras Other symbols. In this way, the computer can recognize whether any portion of the projected image has been scattered by certain physical obstacles that are present, such as the user's hand.

 The numbers may be projected on portions of the electromagnetic spectrum that are invisible to the human eye, such as ultraviolet or infrared spectra. The first preferred example is a three-dimensional interactive display with a transmissive fog screen array, which is placed in an array on the ground or suspended from a roof canopy (not limited to the above), and some jets are controlled by a computer. The tube ejection medium and the projector throw image components, and the other ejection tubes do not eject the medium. When the projector throws an image to the screen position, the spray tube ejects the medium, causing the image to be scattered or diffusely spread to expand the viewable area.

The fog screen array consists of an array of injection tubes, each of which is (but not limited to) cylindrically connected to a three-dimensional display and controlled by a computer, each of which is free to move, when many injection tubes work with the three-dimensional display You can display complex 3D graphics. Each jet tube works or stops working under the control of the three-dimensional display. When some of the spray tubes work under computer control, the other spray tubes do not work, so that the entire array only displays the three-dimensional image that the user wants to display, avoiding More unnecessary fog reduces visibility or destroys image quality. There is a certain gap between the injection pipe and the injection pipe. The gap allows the spray tube to move freely. Different projectors project images onto different mist sprayed nozzles that combine to form a three-dimensional image.

 A second preferred example is a three-dimensional interactive display with a reflective fog screen array. Similar to the first preferred example, the fog screens are placed in an array on the ground or suspended from the roof ceiling, and each jet is controlled by a computer. The media and the projector throw image components, and the other jets do not eject the media. The fog screen array consists of an array of injection tubes, each of which is (but not limited to) cylindrically connected to a three-dimensional display and controlled by a computer, each of which is free to move, when many injection tubes work with the three-dimensional display You can display complex 3D graphics. Each jet tube works or stops working under the control of the three-dimensional display. When some of the spray tubes work under computer control, the other spray tubes do not work, so that the entire array only displays the three-dimensional image that the user wants to display, avoiding More unnecessary fog reduces visibility or destroys image quality. There is a certain gap between the injection pipe and the injection pipe so that the injection pipe can move freely. Different projectors project images onto different fog screens ejected by jet tubes, which together form a three-dimensional image.

 The difference from the first preferred example is that when the concentration of the mist sprayed by the plurality of spray tubes is sufficiently large, all the light projected onto the mist is diffusely reflected or scattered to form a two-dimensional or three-dimensional image, that is, the projector And the audience is on both sides of the screen, and the fog is thick enough to occupy a certain volume, so a three-dimensional image is formed and the visible area is enlarged.

 The third preferred example is the design of the shape. The fog screen array and the display are made into the shape of flowers and sand, which results in the effect of Q. It is also possible to add some spices to the mist to imitate the floral fragrance.

 It must be emphasized that the astigmatism medium is not limited to fog, but may be an air screen array, a water screen array, etc., and may be other substances such as solids or other astigmatism substances.

 According to a second aspect of the invention, a method of operating a computer comprises the steps of:

 (a) A three-dimensional display system comprising a display housing, a medium capable of 3⁄4 inch light and a plurality of projectors for projecting a two-dimensional image onto or into the medium, each projector having an adjustment From the projector to the components of the projected image, and each projector is pivotally mounted to the display housing to adjust the horizontal and vertical position of the projected two-dimensional image relative to the projector;

 (b) displaying a three-dimensional object on the three-dimensional display;

 (c) displaying symbols associated with programs, functions, data or equipment on the surface of the object;

(d) detecting whether the position of the user's hand is near the surface of the object, detecting whether there are other objects near the surface of the object; (e) Activate the function, activate the function, data, or activate the function associated with the device represented by the symbol based on the symbol displayed near the point at which the user's hand is detected.

 The method of the operation meter M1 further includes the following steps:

 (f) reducing the size of the object displayed in step (a);

 (g) Display a new object representing the contents of the device that has started the program function, the element that loaded the data, or the symbol that the user selected in step (c).

 The method of operating a computer provides highly visible human-computer interaction, and the user experiences the advantages of three-dimensional space to understand, for example, the data organization of his viewing. This allows users to quickly understand complex interrelationships and functions compared to traditional two-dimensional interfaces.

 According to a third aspect of the invention, a method of browsing the World Wide Web comprises the steps of:

 (a) A three-dimensional display system comprising a display housing, a medium that scatters light, and a plurality of projectors for projecting a two-dimensional image into or onto the medium, each projector having an adjusted projection The instrument is attached to the projection unit, and each projector is pivotally mounted to the display housing to adjust the horizontal and vertical position of the projected two-dimensional image relative to the projector;

 (b) displaying the first web page on the three-dimensional display;

 (c) detecting whether the position of the user's hand is near the displayed web page, detecting whether there are other objects in the vicinity of the displayed web page;

 (d) If it is detected that the user's hand is located near the hyperlink on the first web page, the first web page is zoomed out and the target web page of the hyperlink is displayed in a larger size.

 Similar to the method of the second aspect of the invention, this method provides the user with further perception and understanding of the interworking characteristics of the web pages they access. When accessing any particular page, the user is not only aware of where he will go from the page, but also where to get there. In this way, it is easier to implement non-linear browsing that includes backtracking to previously visited sites and the information is more easily absorbed by the user.

 Web pages can be written in a markup language that defines the three-dimensional position of each element. Therefore, such a web page is optimal for the display and interaction method according to the third aspect of the present invention.

 Optionally, a three-dimensional font defining the three-dimensional position of each page element is applied to an HTML or XHTML web page designed to be displayed in a standard two-dimensional browser.

Description of the crane embodiment

 Referring first to Figure 1, a three-dimensional display system is generally identified by 10. The display system 10 includes a plurality of projectors 12, a plurality of cameras 22, a display housing 24, and a fiber meter 26. The expander 12 projects the two-dimensional image component 102 into the space in front of the display system 10. The two-dimensional image component 102 is combined to form a three-dimensional image 100 in which the image 100, image component 102 is astigmatized by the substance 103, thereby enlarging the image visible area. The substance may be a gas screen, a mist screen, a 7 screen, etc., or a substance such as a solid state. This patent mainly applies gas screens and fog screens.

 The structure of each of the swells 12 is shown in FIG. Each projector includes a block housing 14, a two-dimensional display screen 16, a zoom lens 18, and a modulator 20. The housing 14 is a rectangular prism. The two-dimensional display screen 16 is at one end of the elongated casing 14 and the zoom lens 18 is at the other end. The modulator 20 is located substantially a quarter of the distance between the ends, and is closer to the zoom lens 18 than to the display screen 16.

 The two-dimensional display screen 16 is an LCD display controlled by the meter 26 in this embodiment. Display screen 16 is backlit. In use, an image component is displayed on the display screen 16, and the zoom lens 18 and the modulator 20 are adjusted to display a sharp image at a spatial point that is adjustable from the projector 12. The ± 夬 housing 14 is made of an opaque material so that light does not pass between the swells 12 mounted on the same frame, causing interference. The zoom lens 18 may be a liquid zoom lens, for example, disclosed in GB Patent 2432010 (Samsung).

 Modulator 20 and/or lens 18 may introduce an aberration of the image component 102. Distortion is a type of aberration that may be introduced that can be predicted by computer 26 and compensated by introducing inverse distortion of the image sent to two-dimensional display screen 16. The spherical aberration can also be corrected in this way, although in many cases the audience will not notice the spherical aberration.

 However, the image component 102 has a small visible area in which the eye 112a can see the image component 102, but the eye 112b and the eye 112c in this area do not see the image. Therefore, the fog screen in Figure 3 can solve this problem.

The fog screen is shown in Figure 3 to provide a cloud of suspended particles (astigmatism) 103 in the air to form a translucent mist. This allows the expander 12 to swell an image that floats in the air. The ship chooses a fog screen to create an unobstructed fog that is invisible to the viewer or barely visible. The camera can optionally be replaced by other devices capable of projecting points, pixels or image components in space. For example, a laser can be used to excite visible radiation in a gas.

 It is contemplated that some or all of the projectors constitute a structure capable of projecting a hologram, including a laser and a photographic film having a previously recorded hologram.

 Referring now to Figures 4 and 5, each of the apparatus 12 is mounted on the display housing 24 such that it can be rotated about either of two vertical axes AA and BB, the vertical axis being located at one end of the block 12 and with the display screen 16 Located in one plane, and each is perpendicular to the side of display screen 16. Each projector 12 can also be rotated 90 degrees along the major axis of the prism or frustum of the projector housing. The accessory is mechanical and can be controlled by computer 26 such that, in use, each projected image component 102 is moved in a horizontal X direction parallel to the surface of display system 10 by rotating projector 12 about axis AA, Each of the expanded image components 102 is moved in a vertical Y direction parallel to the surface of the display system 10 by rotating the expander 12 about the axis BB, and each projected image component is adjusted by adjusting the zoom lens 18 and the modulator 20. 102 moves in a Z direction perpendicular to the surface of display system 10. The choice of housing is beneficial because it enables more flexible placement of the image components 102 that form the three-dimensional image 100.

 In the present embodiment, the display screen 16 is square. However, other shapes of display screens can be used, and this is the case for 90 degree rotation trees having different aspect ratios of different two-dimensional image components 102.

 An arrangement of the projector 12 within the display housing 24 is shown. The arrangement of projector 12 can be selected to best accommodate the shape of the image on the display to be displayed on the display.

 In use, as shown in Fig. 7, the three-dimensional image 100 is projected by the display device 10 and is composed of a plurality of image components 102. Depending on the location of the viewer 112, part of the image component 102 will fall into the viewer's field of view, while others will not be visible. This is consistent with the user body of a real three-dimensional object: only parts that are not obscured by other parts are visible. In the figure, the eye 112a will see the image component 102, and the eyes 112b and 112c will not be visible. Each image component can be seen by an observer over a range of angles that the observer cannot see outside of the range of angles.

FIG. 8 shows that the three-dimensional image 100, under the action of the astigmatism medium 103, aligns the light of the image, thereby expanding the visible area of the image. From the glasses 112a up to the viewers of all positions of the glasses 112g to see. This astigmatism medium can be, but is not limited to, an air screen, a fog screen or a water screen, etc. It can also be other states such as solids. The fog screens are mainly introduced as an astigmatism medium 103 side by side in an array. From Fig. 9 to Fig. 19, the visible areas of the various fog screen arrays for expanding the three-dimensional image are described. Figure 9 illustrates one embodiment of generating a astigmatism material to expand the visual range of a three dimensional image: a fog screen array. The Jilong 26 controls the three-dimensional display 10 and the mist screen array 104. The three-dimensional display 10 includes a plurality of projectors 12 as described above, and the mist screen array 104 includes a plurality of freely movable spray tubes, which can be divided into two categories: Sprayed spray tube 105a and spray tube 105b without spray. When the projector 12 in the three-dimensional display 10 throws the image component 102 to a certain spatial position, the mist 103 ejected from the corresponding spray tube 105a scatters the image thereon to enlarge the visible area of the image, and the others do not work. The spray tube 105b is not sprayed to avoid affecting image quality. When these image components 102 are combined, a three-dimensional image 100 is formed, and the eyes 112 are visible at various positions. This figure shows a floor-mounted fog screen array 104. The fog screen array can also be hung on the ceiling, as shown in the figure below.

 Figure 10 shows a three-dimensional display 10 with a suspended fog screen array 104. The principle of fog-screen array imaging is completely the same as that of the floor-standing fog screen array. The only difference is that the fog screen array 104 is suspended from the sky. It is emphasized that the fog screen array 104 is not limited to the above two positions, and can be placed at other positions.

 Fig. 11 shows that the spray tube 105a of Figs. 9 and 10 is free to move and spray the mist 103. Figure 12 shows that in Figure 9 and Figure 10, under the control of the cage 26, the spray tube 105a is free to move to different positions and spray the mist 103. The projector 12 of the three-dimensional display 10 is free to move to different positions and throw the image component 102 to the mist. On screen 103, projector 12 and spray tube 105a may be placed on, but not limited to, a wall or ceiling.

 Figure 13 shows a three-dimensional interactive display 10 with an array of fog screens 104. Under the control of the computer 26, the three-dimensional display 10 throws the three-dimensional image 100 onto the fog screen 103, and the jet tube 105a ejects a very thick mist 103 to enlarge the image, thereby enlarging the visible area of the image. The remaining spray tube 105b does not work. The fog screen array 104 is on the ground.

 Figure 14 shows a suspended three-dimensional interactive display 10 with a reflective fog screen array 104. It must be emphasized that this patent only discloses two ways to prevent fog screen arrays, but is not limited to these two.

Figures 15 and 16 show that the spray tube 105a of Figures 15 and 16 ejects a very thick mist screen 103, while the projector 12 in the three-dimensional display 10 throws the image component 102 onto the fog screen 103 because the fog screen 103 is very Thick, all the light of the image component 102 is reflected or scattered back, so The viewable area of the image component 102 is enlarged so that it is visible from the eye 112a to the eye 112g. Figure 17 shows that the spray tube 105a of Figures 15 and 16 is free to move and spray the mist 103. FIG. 18 illustrates the disadvantages of displaying image component 102 with transmissive fog screen array 104. The spray tube 105a in the figure ejects the mist screen 103, the projector 12a needs to throw the image component 102a to the right as shown, and the camera 12b needs to throw the image component 102b to the left side of the figure, but the fog The position of the screen 103 and the transmissive manner, that is, the observer 112 and the expander 12 or the three-dimensional display 10 must be on both sides of the screen (see Fig. 10) such that the optical paths of their respective image components 102a and 102b are fogged to the screen 103. It was truncated, so it could not achieve the desired effect.

 Fig. 19 shows that the I-type fog screen array 104 solves this problem. The spray tube 105a in the figure ejects the mist screen 103, the projector 12a throws the image component 102a to the right as shown, the projector 12b throws the image component 102b to the left side of the image, and the fog screen 103 images the image. The components 102 are shot or scattered in such a way that the optical paths of their respective image components 102a and 102b are not intercepted by the fog screen 103, and the correct imaging is at the desired position to achieve the desired effect.

 Figure 20 shows a three-dimensional display 10 with a fog screen and a fog screen array 104 in the shape of flowers and sand. Corresponding to Fig. 1, the three-dimensional display system is generally identified by 10. The display system 10 includes a plurality of cameras 12, a plurality of cameras 22, a display housing 24, and a meter M16. Projector 12 projects a two-dimensional image component 102 onto a fog screen array 103 in front of display system 10. The two-dimensional image component 102 is combined to form a three-dimensional image 100, which enlarges the imaging visible area, and each projector 12 is formed into a flower-shaped shape. The display housing 24 is divided into three parts and has different shapes: a petal shape 24a, a disk and a receptacle 24b, and a sand grain 24c. The petals 24a are responsible for protecting the projector 12 and can be closed or opened. A plurality of cameras 12 are mounted on the faceplate and the receptacle 24b. When the needle-shaped three-dimensional display 10 is closed, the sand-shaped 24c chassis wraps the flower three-dimensional display 10 as shown in FIG. The built-in electric lift 106 is responsible for controlling the lifting of the flowers. Similarly, the fog screen array 104 is also formed in a flower shape, and the spray tube 105a sprays the mist 103 to frame the image component 102 and the three-dimensional image 100 to enlarge the visible area of the image, wherein the working spray tube 105a and the inoperative The spray tube 105b is made into a flower-like shape.

 Fig. 21 shows the sand-like 24c casing of Fig. 20 in the case where the entire flower is closed, on which a plurality of instruments 12 and a plurality of cameras 22 are mounted.

Figure 22 shows the three-dimensional display profile 10 of Figure 20 with the entire flower half open. Under the control of the computer 26, the lift 106 lifts the flower from the gravel-shaped casing 24c, and the disk and the receptacle are 24b. With a plurality of 3⁄4⁄4 instruments 12, the petals 24a are opening.

 Fig. 23 shows that in the case where the entire flower is fully opened, the three-dimensional display system of Fig. 20 has the outer shape 10, the petals 24a are completely open, the petals 24a are fully opened, and the stamens (the plurality of instruments 12) are stretched.

 Fig. 24 shows the flower-shaped mist screen array 104 of Fig. 20 closed, and the petals close the wrapped flower (spray tube 105b).

 Fig. 25 shows the flower-shaped mist screen array 104 of Fig. 20 with the petals fully open, the petals (spray tube 105a) ejecting the mist 103, and the other spray tubes 105b not working.

 The entire flowering process, that is, the process of starting the three-dimensional display with a fog screen in the shape of a flower and a gravel, is shown from Fig. 21 to Fig. 25. The flower 10 is closed in the grit 24c, then gradually rises from the grit 24c, and is opened, while the flower-shaped fog screen array 104 is also gradually opening the spray 103. When the flower 10 is completely in full bloom, the three-dimensional image 100 shows the flower in the flower 104. 105a sprayed on the fog screen 103.

 From Fig. 21 to Fig. 25, the process of closing the entire flower, that is, the process of closing the three-dimensional display of the flower-and-gravel-shaped misty screen, is completely reversed from the above-described opening process.

 The three-dimensional image 100 is capable of allowing a user to interact with the image 100 on the three-dimensional display 10 in response to the presence of a physical object.

 Figures 26 through 28 illustrate a number of example interactions. In Fig. 26, the projected image 100 is a curved thin plate. It can be seen that the three-dimensional image responds to the user's touch like a physical curved sheet. In Fig. 27, the projected image 100 is a fluid surface. When the user's hand 110 hits the image, it can be seen that fluctuations or ripples appear outward from the contact point. In Fig. 28, the projected image 100 is a surface of a soft and non-elastic material such as a sand body. When the user's hand 110 hits the surface of the swollen image, a groove is formed on the surface, and the hand no remains after being removed. In the figure, the hand no moves horizontally from the edge to the right to form a linear groove.

The three-dimensional interaction, not limited to the above examples in FIGS. 26 to 28, can be realized by using the camera 22. The camera 22 is placed on the area of the image 100 shadow. As shown in Figure 29, each image component 102 is digitally identified. The small number makes it non-occluded and nearly invisible to the user. The numbers can be projected in invisible parts of the electromagnetic spectrum, such as the ultraviolet or infrared portion. Computer 26 receives the video signal from camera 22 and, because the number in the image component 102 is no longer visible, can identify situations in which image component 102 is scattered due to the presence of the object. In this way, the position of the external object can be recognized, by adjusting the angular position of the video signal transmitted to the display screen 16, the zoom lens 18 and the modulator 20, and the projector 12 on the mechanical accessory so that the three-dimensional image 100 of the job is made Appropriate ^2. Alternatively, computer 26 may be provided with image processing software capable of detecting the position and motion of the object within the field of view of camera 22. This method is beneficial because it does not require digital occlusion of the projected image 100. Image processing techniques are described in Dellaert et al. (2000), Structure from Motion without Correspondence, IEEE Computer Society Conference on Computer Vision and Pattern Recognition, and Hartley and Zisserman (2004), Multiple View Geometry in Computer Vision, Cambridge University Press. Lasers, radars, or similar techniques capable of detecting the position of objects in space can also be used to achieve the same effect.

 The camera 22 can also be used to record the movement of the person. The video stream from camera 22 can be used by computer 26 to construct a three-dimensional model of the scene using known techniques. The three-dimensional model is then played through the three-dimensional display device 10. The record can be stored and transmitted, for example by email, to another person.

 In FIG. 30, three-dimensional computing interface 120 includes a projected image of first three-dimensional sphere 122 that is captured by three-dimensional display system 10. The different storage devices connected to the distress are indicated by letters or symbols 124 on the surface of the first ball 122. Programs or data files can also be represented by similar letters or symbols. When the user touches the symbol, this can be detected by any of the above methods, the size of the first ball 122 is reduced and the second ball 126 is affected by, for example, selecting a file or directory in the storage device, selecting a function, Or select the data in the data file, as shown in Figure 31. Several programs, directories, or files may be opened at any given time, each represented by its own ball, and a smaller ball represents a background task that does not currently experience user interaction. It can be understood that other shapes besides the sphere can also be used for the equipment, the Mif and the data in the H W1 system.

 FIG. 32 shows a three-dimensional web browser 130. Similar to the three-dimensional computing interface 120, the web page 132 is represented by the browser 130 as a ball. When the user touches a portion of the first job, the first ball of the leg is identified to indicate a link to other websites, the size of the first ball is reduced, and the second ball of the large size is displayed to represent the linked page. Web page 132 is specifically designed in the logo language for three-dimensional display, which identifies the three-dimensional position of each component. Optionally, the 3D font is applied locally to a traditional 2D HTML or XHTML web page. The browser can display multiple web pages at the same time. For compatibility purposes, web browser 130 can also display two-dimensional web page 134 without adding a three-dimensional font definition. 3D video can be inserted into a web page.

 The display housing and the opaque expander housing can be made of plastic, and in particular can be made of biodegradable plastic to reduce the ring of the device at the end of its useful life:
