  2. Content • Internet vs the Web • Terry Winograd • Google • Larry Page & Sergey Brin • BBCi • Steve Rogers • Glass Engine • Mark Podlaseck

  3. Terry Winograd Prof. Computer Science at SU Internet vs the Web

  4. Internet vs the Web • 2 differences • Technical • Internet = set of protocols e.g. http, smtp, … • Http = Web • Social-historical • Internet designed by computer scientists • Web too, more for discussion about papers etc. and then later on spread by industry

  5. Ubiquitous computing “People don’t want to interact with computers, they want something to be done.” Mark Weiser

  6. Ubiquitous computing • Spectrum of computers • By inch • By foot • By yard • No need to choose 1

  7. Interaction with the world Move things around Mouse & desktop Manipulation Locomotion Move yourself Go to homepage Where is the server? Where is the site? Conversation • blablablabla… • blebleble… Timesharing system

  8. Founding fathers: Larry Page Sergey Brin Shared interest in data mining Google: founders

  9. Google: How does it work? • PageRank • Tool to compare Web pages • Link between page A and page B = a “vote” by page A for page B. • Votes are weighted • Still not talking about search engine • After experiments, PageRank seemed fit to be a search engine. They named it BackRub.

  10. Google: How does it work? • Download all the web • Store the webpages • And this without incoming money

  11. Google: What’s in a name? • Short, fun name and easy to remember • E.g. Yahoo! • Googol • = 10100 • Misspelled by accident • Google.com available

  12. Google: no. 1 company to work for http://money.cnn.com/magazines/fortune/bestcompanies/2007/snapshots/1.html

  13. Google: 10 truths • Focus on user and all else will follow • It’s best to do one thing really, really well • Fast is better than slow • Democracy on the web works • You don’t need to be at your desk to need an answer • You can make money without doing evil • There’s always more information out there • The need for information crosses all borders • You can be serious without a suit • Great just isn’t good enough

  14. 1. Focus on the user and all else will folow • Clear and simple interface • Pages load instantly • Placement in search results is never sold to anyone • Advertising on the site must offer relevant content and not be a distraction. Most loyal audience on the Web Google beta Google.com

  15. 2. It’s best to do one thing really, really well • Google = search • Perfect is not possible • “I’m feeling lucky” 3. Fast is better than slow • Google may be the only site that wants its users to leave their site as quickly as possible • “snippets”

  16. Google: (too) popular(?) • AlltheWeb • Imitation • Google Earth • Helps terrorists to plan attacks • Store personal info • Find personal info about founders

  17. Steve Rogers Philips Electronics (VCR) Challenged to structure info on bbc site Duplicate links BBCi: Designer

  18. BBCi: Function • Web-based news parallel with tv and radio • Funded by government • Sense of local community & social responsibility • Safe environment • To help people in digital world • Intuitive look • Dialogue • Chat • Message boards • bbc.com

  19. Site must be able to adopt to certain persons “digital patina” Not just functional & useable, but also pleasant Promotional picture bbc.com BBCi: Personalisation

  20. BBCi: Search • Search • “we find exactly what you need in the BBC (and if we don’t, we’ll make it easy for you to find it somewhere else)” • Toolbar at top of page • Like tabbed browsing

  21. Mark Podlaseck IBM Finding right song Navigational problems The Glass Engine

  22. The Glass Engine • Alternative for search box • Browsing • Easier to make micro-decisions (I don’t like; I don’t like; I like!) instead of looking for something with some properties • E.g. scan for radio station • http://www.philipglass.com/html/pages/glass-engine.html

  23. The Glass Engine • Testing failed • Bars represent properties not time • Lead to redesign: • No colors • Two-way arrow as pointer • Central hairline • Also useable for other stuff than music • E.g. sleeping bags
