  1. WAP Application UsabilityIn GSM MarketsOctober 2000 Title slide here Paul Smethers Director of Usability Phone.com

  2. Problem Statement • “Usability” defined as intuitive user interface for average consumers • WAP doesn’t define interaction model • European WAP developers mostly use Nokia’s SDK and interaction model • All WAP browsers have different interaction models • Wireless interaction models are different from PC interaction models

  3. Solution Constraints • The issue is “Interaction” not “Presentation” • Solution must allow for a standard to develop a single application for all wireless devices • Most wireless devices cannot be upgraded by consumers • Consumers will buy whatever device is popular • Consumers will reject wireless Internet if it is not easy to use on their device • It will take 1 year before a new standard can be deployed

  4. Candidate Solutions • Developers build multiple applications • Only solution that works today • Semantically enriched markup language • New tags to allow developers to specify interaction desired • Allow developers to explicitly define interaction model

  5. Browser Differences Example Phone.com style “<select>” WML Element Nokia style “<select>” WML Element

  6. Another Example Yes Phone.com style “<do>” WML Elements No Nokia style “<do>” WML Element
