Abstract:
A system comprising templates for entering and displaying information/data, such as in a Web page or browser, or in the interface for software or an operating system is disclosed. The screen is divided into an array of grids filling the entire area of the template. At least one, and preferably a majority of the grids are dimensioned based on the proportions of traditional Japanese tatami mats. The grids guide design decisions made by the interface designer or graphics designer in carving up and organizing a page, creating an underlying structure and framework for laying out and displaying the information/data. A primary application of the template is in interface and website design, in which the template automatically divides the screen into frames, each frame being used to enter, edit and/or display information on the computer screen or Web page. The system optionally allows an end-user to reposition the grids within the template, reorganizing the information/data to suit specific needs. The system also has application to the control of the directional flow of language, wherein repositionable grids are oriented to facilitate vertical or horizontal flow of text positioned within said grids.

Description:
FIELD OF THE INVENTION 
   The present invention relates generally to screen or page layouts. More particularly, the present invention relates to a method and system for arranging text and graphic images on a computer screen or printed page. The present invention may have applications including the design and layout of World Wide Web sites and operating system interfaces. 
   BACKGROUND OF THE PRESENT INVENTION 
   Initially, the Internet was a private network for government and academia that facilitated the exchange of text-based research across electronically-linked phone lines. More recently, the World Wide Web (“the Web”) has grown from the Internet to include a broader demographic reach by enabling the transmittal of multiple types of media in addition to plain text. However, despite the sophistication of contemporary browser technologies, the web remains an increasingly difficult environment in which to present complex information in a simple manner. 
   In the absence of compositional limitations, content developers try desperately to incorporate a wide variety of material types, including text and images, charts and research databases, stock tickers and transactional services, search engines and reference materials, plus personal files, linked files, and even linked applications. Additionally, this array of content and material types is being delivered and filtered through constantly changing technology and with ever evolving modes of presentation. While there are new and better delivery vehicles for this endless stream of content, what is missing is an underlaying visual structure for organizing and displaying this content. 
   Web-site authoring software assists content developers in creating the hyper-text mark-up language (“HTML”) necessary to enable such material to be “published” on the Web, but the resulting material is often poorly presented, and difficult to access, to navigate, and to understand. Some Web-site authoring tools, such as Fusion™, available from NetObjects of Redwood City, Calif., offer a variety of page templates for the insertion and subsequent display of information including text and graphics. These page templates are professionally designed single pages or forms containing generic content which is used as a placeholder for the content developers to replace with their own content or information. As such, the templates help the web page designer carve up a page or screen and create a framework in which information may be entered and displayed. Fusion™, for example, offers a variety of combined column and row based layout templates, as well as a set of templates designed for specific subject matter such as archives, billing forms, calendar of events, employee profiles, etc. 
   Although generic templates offer an attempted solution to this “web” of confusion, a more harmonious system of templates is needed to make this solution more reliable and more adaptable for different user needs. Accordingly, a system that offers a reliable and flexible toolkit for information architecture and display, and that provides a series of harmonious and coordinated templates to help developers edit, organize, and display their content to the users who need them most, is needed. 
   Further, such a system for information architecture and management has numerous potential applications, including but not limited to a series of layout templates for site-authoring software; an interface structure for user-driven information arrangement within an Internet or Intranet browser (e.g., user-driven personalization in My Netscape™ or My Yahoo™); or an interface structure for organizing files at the level of a computer operating system (e.g. windows sizeable and moveable by a user, but constrained to a given grid, or that open in fixed sizes, or that “snap to” fixed positions on a pre-determined grid structure). In each instance, the proposed invention offers a system for creating order in the display of information. 
   Because information is often presented on a computer screen, the manner of presentation on such a screen is an important aspect of the above objects. Computer screens generally are in the form of a rectangular module. Although at first impression, the shape of a computer screen may be considered uninteresting, user perception of the screen, and the information thereby displayed, is in fact influenced by a host of cultural associations. Consequently, interpretations of something as simple as a rectangle can vary, suggesting different social, symbolic, metaphorical, aesthetic and even spiritual qualities that affect our understanding of, and relationship to, a computer interface through a computer screen. 
   SUMMARY OF THE INVENTION 
   It is therefore an object of the present invention to provide an improved organizational framework for information provided by computer interfaces such as used to create web pages or computer operating systems user-interfaces. 
   It is a related object of the present invention to provide a system that offers a reliable and flexible toolkit for information architecture and display, and that provides a series of templates to help developers edit, organize, and display their content to the users. 
   These and other objects, features, and advantages of the present invention are accomplished in accordance with the principles of the present invention by invoking the geometric and proportional imperatives of the classic Japanese Tatami mat, to provide editing, visualization, and site architecture tools that enable developers to create screen designs, such as Internet or Intranet sites, or operating system user-interfaces, that simplify information by making it visually appealing, culturally relevant, and functionally clear. The seemingly conflicting ideals of computer information sites are resolved in accordance with the principles of the present invention by using design in general (and geometry in particular) as powerful tools for communication, information delivery, and exchange. 
   The present invention provides a design system that consists of a series of grid templates arranged in accordance with the recombinant geometries and compositional imperatives of the classic Japanese Tatami mat. The aspect ratio of the Japanese Tatami mat is based on a double square (a two-to-one ratio), which, in combination, lends itself to the basic proportions of a standard 15-inch computer monitor. The concept behind the present invention—the provision of a graphical grid, based on Tatami mat proportions, for displaying information on a computer screen—is a simple way to approach site design and information organization. The grid provided by the present invention is based on mathematically predetermined proportions—the modules of the grid work in varying combinations and can be repositioned. 
   The above and other objects, features, and advantages of the present invention will be readily apparent from the following detailed description of the invention taken in conjunction with the accompanying drawings wherein like reference characters represent like elements, the scope of the invention being set out in the appended claims.

   DETAILED DESCRIPTION 
   In general, a computer screen or page is in the form of a quadrilateral that may be divided to correspond to a first whole number of dimensional units  10  ( x ) in a first direction of measurement (e.g., height) by a second whole number of dimensional units  10  ( y ) in a second direction of measurement (e.g., width). For instance, as illustrated in  FIG. 1 , a template  20  may have a two-by-two dimensional configuration, i.e., a first measurement of two dimensional units  10  and a second measurement of two dimensional units  10 . Computer templates for entry and display of information are usually subdivided into a variety of shapes having dimensions based on random combinations of dimensional units. In accordance with the principles of the present invention, instead of providing templates having arbitrarily shaped and dimensioned grids, a system of screen templates  20  are provided with a plurality of grids arranged in accordance with the recombinant geometries and compositional imperatives of the classic Japanese tatami mat. The present invention thus provides a design system consisting of a series of templates resembling Japanese tatami mats and thus is referenced herein as “TatamiNet.” 
   The traditional tatami mat is a floor mat or series of floor mats used to define and subdivide space within a given room. The proportions of a tatami mat have been standardized as a rectangle with approximately a two-to-one ratio. The templates  20  of TatamiNet are divided into grids proportionally based on the aspect ratio of the tatami mat&#39;s double square configuration. Thus, the present invention provides a user interface on a computer screen (likened to a room in which tatami mats are to be laid), or document, that is subdivided into a grid of areas herein referred to as “tatami mats”  30 , each mat  30  having approximately a two-by-one dimensional configuration (measurements of dimensional units in a first and a second measurement direction) of a traditional Japanese tatami mat. The grids are arranged to completely fill the entire information area provided by the template. 
   As will be appreciated, various combinations of the TatamiNet may be created based on the basic two-to-one dimensional configuration ratio by combining mats of such proportions. The various templates of TatamiNet are selected and arranged depending on the proportions of the screen and the information to be provided such that the entire screen is divided into grids filling the template area. Thus, a screen having a two-by-two dimensional configuration may be subdivided into two side-by-side tatami mats  30 , as shown in  FIGS. 2A and 2B . A screen with a two-by-three dimensional configuration likewise may be subdivided into an array of three tatami mats  30 , as shown in  FIGS. 3A ,  3 B, and  3 C. In a similar manner, screens with two-by-four dimensional configurations may be subdivided into an array of four tatami mats  30 , as shown in  FIGS. 4A–4E , and screens with a three-by-four dimensional configurations may be subdivided into an array of six tatami mats  30 , as shown in  FIGS. 5A–5K . As demonstrated by  FIGS. 7A–7I  detailing three-by-five dimensional configurations, the present invention is equally applicable to larger and varying screen sizes and proportions. The term “screen” as used herein may refer to the entire physical display, or as would be understood by those of skill in the art, a portion or window of the display. It will be further understood by those of ordinary skill in the art that the approximate two-by-one dimensions of the mats may be varied at a minimum in an amount sufficient to allow the application of the present invention to screen ratios of standard computer displays. 
   Because the dimensional configuration ratio, rather than the actual size, is the basis for the shape and dimension of mats  30  of the templates  20  of the present invention, the screen may be divided into larger-sized mats of the same traditional Japanese tatami mat two-by-one dimensional configuration ratio. For example, a screen larger than a two-by-four dimensioned screen, such as the three-by-four dimensioned screens shown in  FIGS. 6A and 6B , may be provided with at least one double-sized tatami mat  40  having a two-by-four dimensional configuration (twice the size of the standard two-by-one ratio of mats  30 ). Standard-sized tatami mats  30  are also provided, such that the entire template  20  is subdivided into grids having the proportions of the traditional Japanese tatami mats. 
   Various other template dimensional configurations, for example three-by-five, four-by-four, four-by-five, etc. are possible. Moreover, such dimensional configurations as a three-by-five screen cannot be subdivided into a plurality of tatami mats  30  that would completely fill the screen. Accordingly, as shown in  FIGS. 7A–7I , at least one square grid  50 , having a one-by-one dimensional configuration ratio, must be provided so that the grids of template  20  completely fill the screen. It will be appreciated that a double-sized mat  40  may also be provided in combination with standard-sized tatami mats  30  to fill the screen. Mats  30 ,  40 , and  50  may be arranged in a variety of manners to provide a number of templates  20  each having a different grid arrangement, as may be appreciated with reference to FIGS.  7 A– 7 BD. 
   Although the present invention is specifically directed to the provision of template grids that are dimensioned based on the proportions of the traditional Japanese tatami mat, it is also within the scope of the present invention to provide smaller dimensioned grids. Specifically, square grids  50 , such as provided in the three-by-five dimensioned templates of FIGS.  7 A– 7 BD, which are essentially half of each tatami mat  30 . Thus, any number of the tatami mats  30  of  FIGS. 2A ,  2 B,  3 A– 3 C,  4 A– 4 E,  5 A– 5 K,  6 A,  6 B, and  7 A– 7 I may be further divided into individual square grids  50  having a one-by-one dimensional configuration ratio, so long as the grids of the desired dimensions fill the screen. This aspect of the present invention is consistent with the principles of the use of the tatami mat as a measure of space in Japanese architecture, wherein a room, or space, may be measured in both whole (a double square) and half (a single square) measures of Tatami. 
   Exemplary templates based on templates with only tatami mats  30  (grids having the dimensions of a standard Japanese tatami mat), but having square grids  50  instead of only tatami mat  30 , are shown in Figures labeled with the same Figure number of the related template followed by a lower case letter. Thus, a modification of the template of  FIG. 2A , dividing at least one area filled by a single tatami mat  30  in  FIG. 2A  into two side-by-side square grids, is illustrated in FIGS.  2 Aa and  2 Ab. Similarly, FIGS.  2 Ba and  2 Bb show modifications of the template of  FIG. 2B ; FIGS.  3 Aa– 3 Ac show modifications of the template of  FIG. 3A , FIGS.  3 Ba– 3 Bc show modifications of the template of  FIG. 3B ; FIGS.  3 Ca– 3 Cc show modifications of the template of  FIG. 3C ; FIGS.  4 Aa– 4 Ad show modifications of the template of  FIG. 4A ; FIGS.  4 Ba– 4 Bd show modifications of the template of  FIG. 4B ; FIGS.  4 Ca– 4 Cd show modifications of the template of  FIG. 4C , FIGS.  4 Da– 4 Dd show modifications of the template of  FIG. 4D ; FIGS.  4 Ea– 4 Ed show modifications of the template of  FIG. 4E ; FIGS.  5 Aa– 5 Af show modifications of the template of  FIG. 5A ; FIGS.  5 Ba– 5 Bf show modifications of the template of  FIG. 5B ; FIGS.  5 Ca– 5 Cf show modifications of the template of  FIG. 5C ; FIGS.  5 Da– 5 Df show modifications of the template of  FIG. 5D ; FIGS.  5 Ea– 5 Ef show modifications of the template of  FIG. 5E ; FIGS.  5 Fa– 5 Ff show modifications of the template of  FIG. 5F ; FIGS.  5 Ga– 5 Gf show modifications of the template of  FIG. 5G ; FIGS.  5 Ha– 5 Hf show modifications of the template of  FIG. 5H ; FIGS.  5 Ia– 5 If show modifications of the template of  FIG. 51 ; FIGS.  5 Ja– 5 Jf show modifications of the template of  FIG. 5J ; FIGS.  5 Ka– 5 Kf show modifications of the template of  FIG. 5K ; FIGS.  6 Aa– 6 Ac show modifications of the template of  FIG. 6A ; and FIGS.  6 Ba– 6 Bc show modifications of the template of  FIG. 6B . 
   It will be appreciated that the principles of the present invention may be applied to provide a large variety of screen template configurations for a variety of data/information entry and display programs and situations. The content developer, or user, thus has great latitude in customizing the screen to best suit his or her needs and/or tastes. The division of the screen into elongated units having the dimensions of a traditional Japanese tatami mat, as well as square units as desired, also permits a variety of arrangements of data or information. The templates may be rearranged, as desired, to reconfigure and reorganize the mosaic of information displayed by the screen in its entirety. It is also within the scope of the present invention to permit rearrangement of grids of templates  20  as desired by the end user to rearrange grids to suit his or her needs and/or tastes. 
   Working with the TatamiNet family of templates, a content developer may program a site to allow users the opportunity to configure their screens through geometric rearrangement to allow for cultural preferences. For example, the text to be displayed may either be read in the vertical direction (e.g., Japanese) or in the horizontal direction (e.g., English). In particular, the on-screen information presented is subdivided into a number of grids making up a template having the dimensions of the screen on which the template is to be used and displayed. The content developer may create multiple pages within the same general grouping (e.g., 2×2, 2×3, etc.) to allow the end-user to choose the compositional model that best suits their cultural preference: left to right, top to bottom, or a combination of the two. In this way, (as discussed in more detail below with reference to  FIG. 10 ) the interface can be customized at will to suit not only the tastes and aesthetics of users at large, but also the orientation demands of either the Japanese (and more generally, Asian) or the Western user. Alternatively, the screen may be programmed to automatically generate alternate configurations within the same TatamiNet groupings, to allow the end-user to select any configuration within the grouping. The system may also be configured to query any language preferences stored on the end-user&#39;s computer or otherwise associated with the user. 
   The templates of the present invention may be provided as a series of templates for web authoring tools, such as Fusion™.  FIG. 8  shows the difference between a Web authoring program using a prior art screen division,  FIG. 8   a , and one using a template system of the present invention,  FIGS. 8   b  and  8   c.    
   Alternatively, the templates of the present invention can be implemented in various interfaces and programs as a system of repositionable frames with a grid: e.g., as a browser interface, as a plug-in to a browser, as an add-on to an internal communications application, or as a series of templates that work on “snap-to guides” within any software programs containing layout capabilities (e.g., Quark™, Filemaker™, etc.). In every instance, the templates automatically divide a screen into frames, each frame being used to enter or display data, information, graphics, etc., as desired. These frames may act as HTML-like frames. In some instances, the interface might allow the user to reposition the frames within the overall grid system. 
     FIGS. 9   a–c  show various examples of how such repositioning would appear to the user. The transition from screens  9000  to  9000 ′ in  FIG. 9   a  shows a typical example in which a mats may be enlarged or decreased while maintaining the proportions of the present invention. Graphic mat  9001  is shown as enlarged to  9001 ′, mats  9003 ,  9004 ,  9005  and  9006  are decreased in size to  9003 ′,  9004 ′,  9005 ′ and  9006 ′, while mat  9002  maintains the same size but changes in orientation to  9002 ′. 
     FIG. 9   b  illustrates a typical implementation of this system as a so-called “desktop display” for an operating system. Screen  9010  illustrates a typical desktop display for a system using the present invention. A first section of the screen  9012  is used to display e-mail information, and a second section  9011  displays a web browser. The user may wish to focus on the web browser  9011  by increasing its size and changing its location. The system increases the size of web browser  9011 ′ and decrease the size of other grids  9013 – 9016  to  9013 ′– 9016 ′. Certain applications, such as e-mail  9012  may be selected to maintain their size  9012 ′. As illustrated, although the size and location of the grids is changed, the system maintains the proportions of the present invention.  FIG. 9   c  also shows a transition wherein individual grids change size, but the overall system maintains the proportions of the present invention. 
   As illustrated in  FIG. 10 , the interface may allow the user to have directional text flow correspond to the vertical or horizontal orientation of the frame within the grid. Thus, for example, a user viewing language having a horizontal directional flow may prefer a horizontal orientation for the mat containing such information (i.e. a 2×1 mat wherein the mat is 2 dimensional units high (horizontal axis) and 1 dimensional unit wide (vertical axis)), while a user viewing language having a vertical directional orientation may prefer a vertical orientation for the mat containing such information (i.e. a 1×2 mat wherein the mat is 1 dimensional unit high (horizontal axis) and 2 dimensional units wide (vertical axis)).  FIG. 10  shows an example of how such directional text flow would appear to the user changing from a screen  1000  having a vertical directional text flow, as may be preferable for the English language, to a screen  1000 ′ having a horizontal directional text flow, as may be preferable for the Japanese language (the term “text” including character based languages). Screen  1000  is divided into several TatamiNet mats, including mats  1001 ,  1002  and  1003  having a text in a vertical orientation as indicated by symbols “&gt;” and mat  1004  displaying graphic information. For a Japanese language orientation screen  1000 ′, text mats  1001 ,  1002  and  1003  would be converted into mats  1001 ′,  1002 ′ and  1003 ′ having a horizontal orientation as indicated by symbols “v”. As noted above, the system may allow the user to switch between vertical and horizontal orientations, or the orientation may be automatically changed based on the user&#39;s selected language which may be automatically selected based on user configuration information. Thus, TatamiNet may be used in many situations or applications requiring the entry and/or display of data or information, such as text or graphics. 
   While the foregoing description and drawings represent the preferred embodiments of the present invention, it will be understood that various additions, modifications and substitutions may be made therein without departing from the spirit and scope of the present invention as defined in the accompanying claims. In particular, it will be clear to those skilled in the art that the present invention may be embodied in other specific forms, structures, arrangements, proportions, and with other elements, and components, without departing from the spirit or essential characteristics thereof. For instance, it will be appreciated that each template of the present invention is divided into grids that are preferably based on the dimensions of a Japanese tatami mat, it is within the scope of the invention to provide grids with different dimensional configurations as discussed above. One skilled in the art will appreciate that the invention may be used with many modifications of structure, arrangement, proportions, and components and otherwise, used in the practice of the invention, which are particularly adapted to specific environments and operative requirements without departing from the principles of the present invention. The presently disclosed embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims, and not limited to the foregoing description. 
   Further, applications today primarily deal with the screen as a flat surface or two-dimensional space; in the near future, it is envisioned that the proposed invention would have application as well to the design and architecture of space conceived as virtual or three-dimensional. One example of such a potential development would solve the current problem where delving into a website involves going from one page to the next, flat pages “linked” to other flat pages. An after-arising development could allow one to enter “into” a page, delving into a complex TatamiNet grid of information that rests within a single tatami shape sitting within a TatamiNet grid.  FIG. 11  shows an example of how the TatamiNet grid of information can be delved into by a user, taking one grid  1101  of the screen  1100  and enlarging it into it&#39;s own series  1111 – 1118  of TatamiNet grids. Likewise grid  1118  is enlarged into a new series  1120 – 1123  of TatamiNet grids.
