DISPLAY METHOD FOR MULTIPLE LAYERED SCREENS

Abstract: A method of displaying data or images, on a multi-level screen display, assigns screen designation codes to respective software components, to determine the physical screen on which the corresponding images or software components are displayed. The screens may comprise layered liquid crystal displays. The method allows a user to see overlaying objects at the same time. For example, with drawing software one can simultaneously display toolbars or menus on a front screen, and a drawing image on a background screen.

Description: DISPLAY METHOD FOR MULTIPLE LAYERED SCREENS TECHNICAL FIELD This invention relates to software visual effects. BACKGROUND ART Many software programs these days display information on a screen using effectπeh a multi-layered approach. For example, a drawing package may have a central area which the software user can draw upon. In a typical drawing package there are many drop down menus, tool bars, cursors or templates which effectively overlay the drawing on the screen. The reason for this is that there is only limited screen area available. Thus, for the user to be able to \ ιew the functions to be selected, some of the drawing space has to be borrowed for this. Often, the user is placed in the undesirable position of having to move around the tool bars and menus if possible, or alternatively move the drawing (or whatever file the user is working on) so that the user can actually see parts of the drawing formerh obscured by the menus and so forth. There is another related problem experienced by software users, particularh in relation to drawing packages, but not exclusively. Often when compiling a drawing, it is necessary to compile the drawing using eral layers of "objects". A typical drawing function gives the user the ability to determine whether the object is viewed as being at the back of the picture or overlaying everything at the front of the picture. This can in some cases lead to the objects at the back of the picture being obscured by larger objects at the front of the picture. Thus, the user cannot readily select the object at the back of the picture with it being obscured. This is understandably frustrating and can impede the users' ability to work efficiently, often requiring the user to move the front object so as to gain access to the back object. This frustration is riot limited to drawihg packages. It can also be frustrating to not having ready access to the multiple levels in such diverse applications as geographical information system (GIS) programs, including medical models, instrumentation Using browsers for the internet or game software, for example flight simulators. All of the aforementioned packages have information on various levels with which the user would desire ready access to. It is an object of the present invention to address the foregoing problems or at least to provide the public with a useful choice. Further aspects and advantages of the present invention will beco e apparent from the ensuing description which is given by way of example only DISCLOSURE OF INVENTION According to one aspect of the present invention there is provided a method toi creating a visual effect in the display of software wherein the software is for the presentation of data or images on a screen using software functions. the method characterised by the steps of a) assigning a particular screen designation code to some soltware components. and b) assigning other screen designation code to other components of the software - wherein the screen designation code determines which physical screen the image 01 software components is displayed in a multi-level screen display In further embodiments of the invention, the software components being assigned a particular screen designation code all relate to images being manipulated Howe\eι this should not be seen as limiting The image being manipulated can mean the manipulation of any image, whethei the image is in text format, numbers, graphical or otherwise For example, the present invention can be used in relation to software foi woid processing, drawing, financial and scientific information flight simulatois, internet browsers, spreadsheets, slot machines, instrumentation, medical programs, mapping programs, games and the like In some embodiments of the present invention certain software components may be reference data of lessei importance than other data This, is the data ot greatei importance may be assigned to the front screen where as data of lesser importance may be placed on background or midground screen In preferred embodiments if theie is an image on the screen which is being manipulated via software functions - even I I it is a game scene "being travelled through - it has a paiticular screen designation separate to other functions It is envisaged that in most cases, the other components of softwaie aie standaid features which come with the software program For example, screen template, drop down menus, function keys, cursors, tool bars, head-up displays and the like However, in some embodiments of the present invention the different components ot the image may be assigned a separate designation code, for example an object which is laid ovei part of the image In some embodiments of the present invention, the method can be applied to existing software, for example Microsoft Word™. Microsoft Powerpoint™. Adobe Photoshop™, MacroMedia Director ™ and so forth However, in othei embodiments of the present invention there may be created software which uses the principles behind the present invention The screen designation code is merely a code that identifies which physical sci een the image or software component is displayed upon The inventors of the present invention also invented a multi-level screen display and this is described in detail in PCT Application Nos PCT/NZ98/00098 and PCT/NZ99/00021 This is a device which is created by combining multiple layers of selectively transparent screens Each screen is capable of showing an image In preferred embodiments, the screen layers are liquid crystal displays Preferably the screens die aligned parallel to each other with a preset distance between them With this invention, images displayed on the screen furthest from the view (background screen), will appear at some depth behind the images displayed on the screen closest to the viewer (foreground screen ■ The transparent portions on the foreground screen will allow viewers to see images displayed on the background screen This arrangement of layering multiple screens allows images to be presented at multiple levels giving the viewer true depth without use of glass oi lens The present invention shall now refer to use with a multi-level screen as descπbed above although this should not be seen as limiting It should be appreciated that although reference shall be made throughout this specification now to only background and foreground screens, other aspects of the present invention may utilise more than two screens For example, with drawing packages all of the readily useable software functions may be on the foregiound while various layers of the drawing may be on the multiple screens behind the foreground screen With the present invention, a screen designation code may be used to place all of the standard software functions, templates, tool bars and the like on the foieground screen However, the image being worked upon may be placed on the backgiound screen. This arrangement allows the user of the software to effectively look behind the foreground components to view the image being manipulated This ability may be enhanced if the traditional opaque backgiound to the functions has varying shades of transparency This feature may be imparted by a veision ot software in accordance with the present invention. Thus, there is now no requirement for the user to move aiound on scieen vanous toolbars and the like so as to get a full view of the image Furthei. if the package is for example, a drawing package, the foregiound and background components may actually be on different screens, again allowing the viewer to view and possibly select the drawing components without one obscuring the other. To allow the drawings components to be readily and/or manipulated, the components themselves may have different transparencies Further, the traditional white palette may be fully transparent There are a number of methods by which the present invention can be implemented In some embodiments of the present invention it may be that existing software is coded to identify screen functions which are normally "always on top" or "always at back". If this is the case, one embodiment of the present invention will be an interface that identifies the coding on existing software with these identifiers and assign the various software components eg toolbar to the appropriate foreground or background screen. The interface maybe a patch for existing software, a display driver, a library file or a he front end for multiple existing software packages or a completely new operating system. Instead of software, graphic cards may be used to divide the images appropriately. This will increase the speed of operation considerably. Further aspects of the present inventions provide a media which can contain instructions for the operation bf method as described. The background fill of 'alwa s oh top' functions can be made fully or partially transparent by the present invention. With existing software that does not have such coding, it may be necessary to implement the present invention by having customised software in which the software developer specifies the software routines which cause the appropriate components and images to go on the appropriate screens. Other aspects of the present invention include not just interface programs which enable existing software to be used on multi-level displays, but original software programs which likewise utilise the concept of having a screen for the file or image being worked upon and other screens for more standard software functions, templates and the like. There is software available which can be used with multiple monitors placed side side. This software has screen designation codes as such, in that the \ -axis coordinate determines on which of the monitors the information is to be displayed. It is envisaged that this software could be used in the present invention with a code which normally would assign an image to a particular monitoi will now assign that image or data pixel to one of the screens in a multi-level dιspla\ Other aspects of the present invention includes an operating system which incorporates the principles of the present invention as previously descubed and also a web browser which also incorporates the principles as previously described It can be seen that the present invention adds a new dimension, literally and figuratively to existing software and potential for new softwaie BRIEF DESCRIPTION OF DRAWINGS Further aspects of the present invention will become apparent from the following description which is given by way of example only and with reference to the accompanying drawings in which Figure 1 illustrates a prior art screen display, and Figure 2 illustrates a foreground screen in accordance with one embodiment of the present invention, and Figure 3 illustrates a background screen display in accordance with one embodiment of the present invention BEST MODES FOR CARRYING OUT THE INVENTION With respect to Figure 1, there is illustrated a typical screen display found in commercial software in this case, the commercial software is Microsoft Powerpoint™ On this display there is an external template (1), two toolbais (2 3), a drop down menu (4) and an image to be manipulated (5) on a palette (6) It can be seen that the toolbars (2, 3) and drop down menu (4) obscure the image (5) and palette (6). With the present invention, the common components of the software can be placed on the foreground screen of a multi-level screen display as illustrated in Figure 2. It should be noted that the palette (6) and the image (5) are not displayed on the foreground screen. Instead, the image (5) is displayed on a background screen as illustrated in Figure 3. With the present invention there is no need to display a palette. The separation of the image (5) from the standard software components ( 1, 2, 3 and 4) is achieved by the present invention assigning screen designation codes to each of these which determine whether they are placed on the foreground or background screen. Again, it should be appreciated that there may be more than two screens and these components can be placed on any of these. Not illustrated is the effect of having the foreground screen over the background screen as this is a 3-dimensional effect difficult to show. However, as the foreground screen is a physical distance from the background screen and transparent in places to respect to the background screen, it is possible for the user to look around and behind the tool bars and drop down menu to view the image on the background screen. Aspects of the present invention have been described by way of example only and it should be appreciated that modifications and additions may be made thereto without departing from the scope of the appended claims.
