Mobility •stationary • nomadic (pedestrian speed) • mobile (vehicular speed) • roaming (mobile across networks)

Connectivity Mobile Device • connected Capability • semi-connected • form factor (asymmetric) •GUI • disconnected •multimedia • real-time multimedia

¾ Restrictions: small memory, slower processors, small bandwidth these are cited often, but less and less relevant • modern mobiles are like PC-s 10 years ago • they are getting stronger every day ¾ Constraints: small overall size, small screen small, only numerical, or no keyboard at all different usage environments (on the street, on a train…) hands-free, one handed, or two handed usage most users are non-technical •systems should work immediately when switching on… • (just like a light switch) ¾ Technical restrictions may become less relevant, but… ¾ …the constraints are bound to stay!

¾ These are not only constraints but also possibilities! merge of cameras, PDA-s, and phones in one device • made possible by the small size develop new types of interaction • made necessary by lack of keyboard and mouse location-specific services • your provider knows where you are, why not making use of this? ¾ Constraints drive innovation… new types of devices, new paradigms come every day contrast with PCs: no major paradigm shift in the past 15 years! ¾ Mobile is one of the most innovative areas these days!

¾ World Wide Web (Tim Berners-Lee, 1989) universe of network-accessible information anyone, anywhere, anytime Client to server interactions • HTML Ftp News Email • URL Web Internet • HTTP Server Resources Db & other software URLs HTML Internet (location (data/display) communication e.g -- http://www.foo.org/boo.html )

Hello There Here’s a zippy HTML page, with lots of protocols Colors and Links ...!!! Fun, Eh? HTTP (transfer)

¾ WAP (Wireless Application Protocol) 1.x Protocol Conversion : Internet Protocol (wired) -> WAP Protocol (wireless) ¾ WAP (Wireless Application Protocol) 2.0 TCP/IP based Protocol WAP client & server support HTTP 1.1 • Protocol parameter & method, Persistent connection .. XHTML, not WML

¾ Wireless Internet 무선을 통한 인터넷 접속을 총칭, 고정 접속만을 지원하는 (B)WLL 등도 포함

¾ Mobile Internet 이동성이 지원되는 무선을 통한 인터넷 접속 무선 인터넷의 일반적 개념으로 사용되고 있음

¾ Mobile Web 이동성이 지원되는 무선을 통한 웹 응용 환경과 HTTP, XML, URI(IRI) 등을 비롯한 웹 기반 기술을 통칭 궁극적인 지향점은 모든 사물을 연결하는 Ubiquitous Web

¾ Question: what does W3C contribute to this environment?

¾ In 2006 mobile Web browsers will support: All de facto Web Standards: HTML, CSS, and DOM Rendering of large Web pages with some kind of ‘small screen layout’ technology Various features for easy access to de facto Web sites SVG Tiny 1.2

Overlapping work must be avoided

¾ W3C submissions (1997/98) "HDML - Handheld Device Markup Language Submission" - Became WAP WML 1.0 "Compact HTML" - Became i-mode ¾ W3C Recommendation "XHTML Basic" (2000) - Became WAP 2.0 ¾ Today: Widespread (X)HTML support in mobile phones

¾ MMS is the next “cool” thing on phones: send/receive messages with multimedia content display those with various timing constraints ¾ There are several MMS formats, each a SMIL profile OMA has a small MMS format, subset of SMIL Basic 3GPP defines an MMS format, between SMIL Basic and full SMIL • this will dominate with better phones W3C has just restarted the SMIL work, may consolidate these…

¾ Timing: SMIL Basic (2001) adopted in MMS SMIL adopted in 3GPP SMIL (2002/03) new W3C SMIL WG to focus on mobile SMIL (2004)

¾ SVG brings 2D vector graphics to the Mobile Web ¾ Numerous implementations (Windows CE, Symbian, for J2ME ...) ¾ Part of 3GPP MMS (Release 5 and 6) ¾ Mobile SVG becoming the vector graphics tool for Mobile!

¾ More and more devices Different characteristics One site per device expensive ¾ Single Authoring: Author once, view anywhere

¾ As we have seen, Mobile devices are very different ¾ Adaptation of content becomes important ¾ CC/PP ("Client Capabilities/Preferences Profile") CC/PP is a general framework OMA defines a CC/PP Profile (UAPROF) for Mobiles protocol adaptation is being worked on ¾ Idea: Describe client environment Hardware (screen-size etc.) Software (OS, browser version etc.) User preferences (Audio on/off)

¾ Mobile keyboards hard to use ¾ Multimodal: Input technologies suitable for mobile Voice Handwriting Gesture ... ¾ Speech Recognition W3C speech interface framework • SRGS - markup for speech grammars • SSML - markup for speech synthesis • VoiceXML - markup for voice dialogs Voice browser: rapidly growing industry
