  2. What is Telematics 2001 2002 2004 2006 2008 2010 Definition of Keyword “Telematics” Overview of “Telematics Services” Car and outer world informatics connection via bidirectional telecommunication methods “Telecommunication Informatics” Telematics Common Information Services Automobile Specialized Services Market Estimation of “Telematics” Navigation & Traffic Forecast News & Information Wireless Communication Emergency Call & Safety Control M-Commerce & Banking Multimedia & Entertainment Remote Maintenance & Software Update Tlematis is the big market which holds potential of 22.1 billion dollars in the world in 2010

  3.

  7. Main Functions of Traffic Information Mixer Structured Matching Process：Generate corresponding structure between Traffic data and Road Map Data Shape Deformation Process：Deform the Shape of Matched Data into the Deformation Map Easy to grasp traffic information Simple Overlapping Structured Matching Shape Deformation Traffic Data (VICS) Summarized Map Matched Data Generate Corresponding Structure between Traffic and Road Map Data Simply Deformated Map overlaid with Traffic Data forms Summarized Map Simple overlap process is impossible to correspond with Traffic & Road Data Background Road Map Data

  8. Display Example of Summarized Map of Traffic Information Area Map Example Route Map Example Firstly displayed by Text Details are displayed by SVG Summarized Navigational Map overlaid with Traffic Info. Summarized Area Map overlaid with Traffic Info. 500m Target Area 1km Middle Area of Route 2km Start Area 4km

  9. Compare with real Car Navigation System Map rotation is not Influenced to Text & Symbol rotations

  10. Display Modeling of Car Navigation System Simple rotating result Text and symbols are simply rotated as if image data Restricted rotating result Text and symbols are restrictedly rotated

  11. Display Modeling of Car Navigation System Simple zoom-in result Text and symbols are too enlarged All lines are too enlarged Restricted zoom-in result Text and Symbols are restrictedly enlarged Selected lines building outlines are restrictedly enlarged

  12. Display Modeling of Car Navigation System Simple zoom-out result All text and symbols are too shrunk All lines are too shrunk Restricted zoom-out result All text and symbols are restrictedly shrunk Selected lines are restrictedly shrunk

  13. Precise Discussions about Restricted Operation Display Example of Rotation strictly based on SVG spec. All of Texts are rotated as if they are Image data ABC ABC DEF DEF GHI ABC DEF GHI GHI STU STU JKL STU JKL JKL Rotate left 45 Rotate left 90

  14. Precise Discussions about Restricted Operation STU STU Display Example of Rotation utilizing “restricted” tag. All of Texts are not rotated, but almost texts are overlapped. Overlapped with each other ABC ABC DEF DEF GHI GHI STU DEF GHI ABC JKL JKL JKL : Operation froze using “restricted” tag Overlapped on another objects Side Effects Occur !!

  15. Precise Discussions about Restricted Operation STU To compensate side effects of “restricted” tag., Dynamic Layout Controlling is necessary ABC ABC DEF DEF GHI GHI ABC STU GHI JKL STU JKL JKL : Operation froze using “restricted” tag : Reference Point is shifted from “ld” to “rd” : Visibility Control

  16. Precise Discussions about Restricted Operation Display Example of Zoom-in strictly based on SVG spec. All of Texts are enlarged as if they are Image data ABC DEF ABC GHI DEF STU JKL GHI STU JKL

  17. Precise Discussions about Restricted Operation Display Example of Zoom-in utilizing “restricted” tag. All of Texts are not enlarged, and also Lines are not enlarged. ABC DEF ABC DEF STU GHI JKL GHI STU JKL : Operation froze using “restricted” tag

  18. Comparison of Solution Approaches Developing Dedicated Browser for Telematics Extension of SVG Spec. Remains Present SVG Spec. as it is, and develops the dedicated browser for Telematics Add the new attribute of element tag which restrict operations such as transform or zoom In/Out ? Extension of SVG Spec. and Browser Functions CSS Styling Extensions Restrict SVG styling properties, and controls detail style descriptions and CSS vinding box controls. Extend SVG Spec. for controlling as it is, and develops the dedicated browser for Telematics Extension of DOM Interfaces From viewpoint of contents distribution, approach of SVG spec. extension is more better !! Restricted operation must be described by IDL for DOM Interfaces IDL operation or evaluation is restricted

  19. Concrete Approach of SVG element tag Extension <?xml version="1.0" standalone="no"?> <!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.1//EN" "http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd"> <svg width="400px" height="200px" version="1.1" xmlns="http://www.w3.org/2000/svg"> <desc>Example RotateScale - Rotate and scale transforms</desc> <g transform="translate(50,10)"> <g transform="rotate(30)"> <g fill="none" stroke="gray" stroke-width="16"> <line x1="0" y1="50" x2="100" y2="50"/> <line x1="50" y1="0" x2="50" y2="100"/> </g> <textrestriction="rotate"x="60" y="30" font-size="20" font-family="Arial" fill="black"> ABC </text> </g> </g> </svg> restriction ABC Element Attribute Attribute Value Descriptions <svg> Basic Shape <path> <g> rotate strokeWidth fontSize rotate=“fixed inclination value” strokeWidth=“restricted range of strokeWidth” fontSize=“fixed font size” hms:restriction

  20. Concluding Remarks and Future Approach SVG open Specification is better for Telematics Application from the view point of contents distribution To realize same display functions of conventional car navigation system, it is necessary to extend SVG spc. for “restriction” operations There are many realizing method for “restriction” operations, but unified regulation is necessary in the large SVG spec. Realize SVG based new Telematics system, which can inter- operate with various contents via broadband wireless networks
