9:00-10:30: Wireless Web Market Opportunity and Strategy

Third Generation Internet Development: New Zealand's Formula for Propelling Mobile E-commerce -- Howard H. Frederick, New Zealand Centre for Innovation & Entrepreneurship, New Zealand

Continuing reduction in the size of computing devices combined with advances in cellular telephony are making the mobile Web a reality. This track will explore Web applications in areas such as personal organizers, mobile phones, Web cams, etc.

  • Market potential - an overview
  • What is mobile e-commerce?
  • New Zealand as 3G Testbed
  • Wellington's WAP business cluster
  • How to overcome "resistance"

Choosing a Wireless Standard Strategy -- Mark Baker, Sun Microsystems

This presentation is based on a detailed technical reading of the Wireless Application Protocol Forum suite, compared with the 'control hypothesis' of adapting current and near-future 'web standards', including XHTML and XSL style sheets. Perhaps the best sense of it can be found in an unrefereed column authored by the originally-scheduled presenter, Rohit Khare, for IEEE Internet Computing, "W* Effect Considered Harmful" (http://www.4K-Associates.com/IEEE-L7-WAP.html)

There was considerable informal interest in these findings at WWW8, but any talk next year (at WWW9) will have to be extensively updated to account for industry developments by then. It is precisely because these choices facing content developers are so chaotic, though, that it may be appropriate to kick off a wireless DevDay track with this sort of debate.

10:30-11:00: Break

11:00AM-12:30: Wireless Web Content Adaptation

Repurposing Content for the Mobile Web -- Rakesh Mohan, Chung-Sheng Li and Brad Topol, IBM

The authors will detail the use of systems we have developed (which is freely available), and their use at both web sites and at proxies serving the mobile devices.

We will also summarize our proposals to the W3C and MPEG-7 standards bodies related to multimedia content for mobile devices. For each such page, an example is chosen and it relevant content is authored in WML (or SpeechML), giving examples of same content in the different markups. Then a translator generator is used to generate a translator between the HTML page and the WML (or SpeechML) page. This translator generator is freely available. We will discuss our experience in using this approach to repurpose news web sites for speech based browser for cars and WML browsers for mobile phones.

Designing the user experience for a mobile web application -- Dena Tepper and Mark Fletcher, Sapient

The objective of this presentation is to discuss an approach to designing the user experience for a mobile phone web application. The presentation will be in two parts. With the goal of creating an application that is both useful and usable the first section will focus on determining which features and functions of an existing HTML portal Website should be included in the mobile version of the application. Emphasis will be placed on identifying which features and functions would be useful to users in a mobile environment and, given both the hardware and software limitations of mobile phones, which functionalities can be made usable.

The Second section of the presentation will focus on a particular feature/function describing and illustrating a proposed interface design. The presentation would include mobile phone browser screen displays of the functionality.

12:30-14:00: lunch with Tim Berners-Lee

14:00-15:30: Mobile content generation techniques

Adaptive Personalization for the Mobile Web -- Michael J. Pazzani and Daniel Billsus, University of California

The DailyLearner is a personalized agent that allows users to access news that interests them from handheld PDAs (such as the Palm VII or other Palm with a cellular modem using the Proxiweb browser), Windows CE with wireless or other Internet Connection, Qualcomm pdQ smart phones, or other "wireless internet" cell phones. The DailyLearner is intended to save users time and transmission costs by providing access to personalized news of World Events, Business, Sports, Politics, Entertainment, etc. The system creates a statistical profile of the user interests, enabling it to determine which headlines to send to the handheld. Several versions for handhelds are available.

The DailyLearner has a client-server architecture. News articles are storied in a database. When the user requests to read news, articles are sorted by predicted interestingness to the user. The original DailyLearner was WWW service in HTML with tables and Java for Web browsers http://dailylearner.ics.uci.edu/. A complete redesign of the interface and user interaction was performed for the HDML (http://hdml.ics.uci.edu/) and WML (http://wml.ics.uci.edu/) versions.

Generating Mobile Content Using XSLT and CC/PP -- Johan Hjelm, Ericsson and W3C

XSLT is a general transformation technology for XML, and given that CC/PP will enable a higher degree of parametrization than UA-headers, it will also be possible to select style sheets that represent the preferences of the user and the device capabilities to a much higher degree than today.

In the presentation, I look briefly into the layout of a couple of XSLT style sheets that can be used to generate content with radically different design (not just presentation, but also content-wise), and how the parametrization of the request can be used to select between different style sheets. I will also discuss matching metainformation from CC/PP and the document profile. I also talk about how this technology can be applied to content generation from a database, and how it can be used to distribute content generation, using proxies (e.g. in conjunction with the WAP gateways).

15:30-16:00: Break

16:00-17:30: Advanced Mobile Web Content

Embedded Web Devices - a Java perspective -- Chris Laffra, Object Technology International

This presentation will discuss:
  • what Java solutions are currently available for embedded
  • how to handle special embedded requirements (e.g. realtime)
  • optimizing Java for embedded
  • eCommerce with Java on embedded devices
  • compressing Java applications
  • communication protocols: JNI, WAP, etc.
  • examples

Summary of the W3C Voice Browser Group Activity -- Dave Ragget, W3C-Hewlett-Packard Labs

Many people are getting interested in the use of mobile phones for accessing web services using speech recognition and synthesis. I am the W3C staff contact for voice browsers and would be very happy to summarise the work being done on this at the W3C and to add my own comments based upon work at HP Labs.
