SVG Advances in W3C Web graphics standards - 2 of 19 SVG 1.0/1.1 Advances in W3C Web graphics standards - 3 of 19 Recommendations since Sep 2001 and Jan 2003 Adoption ●Renderers: Adobe plug-in, Batik, Corel Smart Graphics, etc. ●Editors: XStudio ●Exchange format: Maya 5, Invisio@@ ●SVG Conference SVG Mobile Profiles Advances in W3C Web graphics standards - 4 of 19 Recommendation since Jan 03 ●SVG Tiny ●SVG Basic ●Adoption SVG 1.2 Advances in W3C Web graphics standards - 5 of 19 Second working draft released Apr2003 ●adds: rendering XML ●adds: flowing text ●adds: audio/video SVG Print Advances in W3C Web graphics standards - 6 of 19 Authoring Guidelines, not a profile Requirements document published Feb 2003 ●No animation or scripting ●Color reproduction ●Page layout ●Multiple part (fonts, images) aggregation Multimedia Advances in W3C Web graphics standards - 7 of 19 Multimedia: SMIL Advances in W3C Web graphics standards - 8 of 19 SMIL 2 Recommendation since Aug 2001 ●Adoption: animation markup included in SVG ●3GPP has defined a profile of SMIL for MMS messages ●Implementations: Qi mobile browser, X-Smiles, RealOne, IE, etc. Multimedia: Timed-Text Advances in W3C Web graphics standards - 9 of 19 New Working Group ●movie subtitling ●captioning for accessibility ●scrolling news items ●karaoke! ●Credits Currently, several incompatible formats exist, causing interoperability problems when used within SMIL. Main idea is decouple video and timed-text. Multimedia: Timed-Text Requirements Advances in W3C Web graphics standards - 10 of 19 15 May 2003: Use cases and requirements document ●suitable for text captioning ●allows for description of content ●streamable, user-customisable, etc. ●internationalised XHTML2 / XForms Advances in W3C Web graphics standards - 11 of 19 A new HTML ●Cleans up HTML, but not backwards compatible ●Leaves presentation to CSS ●Fully XML ●Modular A new forms language ●Content cleanly split from presentation: abstract controls and presentation bindings ●Controls can be tied to other fields: activate, default value, etc. ●Can return any XML instance, following a given template ●Support for XML Schema types: date, float, etc. Currently a Candidate Recommendation, lots of implementations, should be finalised this year CSS Advances in W3C Web graphics standards - 12 of 19 Powerful styling for XML CSS2 ●4 years old, but doing well ●Modern browsers now fully implement it ●allows attractive designs but remains simple and accessible CSS3 ●Many new properties: color, internationalisation ●Profiles for mobile devices, interactive TV Multimodal Advances in W3C Web graphics standards - 13 of 19 The future of HCI is the future of the Web ●Voice, Handwriting, Keyboard: all at once ●Mobility: mobile phones, PDAs, cars... ●The Web is the main application: ●A lot of information out there ●Systems will use HTTP, SOAP, RDF, etc. W3C started a Working Group on 2002 43 Companies, 79 Participants. Goals: ●Definition of a Framework ●Components: ●Ink, Voice ●System and Environment ●Merging Information ●Annotating input More on multimodal interaction * Part II Advances in W3C Web graphics standards - 14 of 19 Integration ●Component integration ●Device integration Component integration Advances in W3C Web graphics standards - 15 of 19 How to handle mixing namespaces While the specs define how everything works together in terms of syntax (XML, namespaces, styling, etc), making it work in implementations can be tricky ●It works in monolithic software: e.g. X-Smiles, Mozilla, written in a modular fashion. ●But there are problems if integrating modules from different vendors, i.e plug-ins Component extensions ●Goal define an API for plug-ins ●Requirements: ●Rendering: allocation of boxes, line breaks ●propagation of events, CSS ●Error handling ●Nesting/reentrance ●... Work has not started, but pressure is mounting Device integration Advances in W3C Web graphics standards - 16 of 19 Fewer computers are desktop machines. Old specifications are big and inadapted to mobile phones, or PDAs Therefore, a lot of specs are being modularised: ●CSS: TV Profile, Mobile Profile, Media Queries ●XHTML Modularization ●SVG: Basic and Tiny profiles Device Independence Advances in W3C Web graphics standards - 17 of 19 Not only specifications are designed as modular, but the W3C are also working on a complete device independence framework CC/PP ●Language for device description and user preferences ●content adaptation mechanisms (client/server, etc.) ●Authoring guidelines Multimodal Interaction Advances in W3C Web graphics standards - 18 of 19 Same as CC/PP for device description, but extended requirements: ●Concurrent input and output devices ●Environmental factors: geographical position, surrounding noise... ●Session migration: car to pda to phone, etc. Fine Advances in W3C Web graphics standards - 19 of 19 ●A lot of activity going on at W3C ●Graphics standards always evolving ●...to make a better Web If you want to know more, or participate, email me (mf@w3.org)
