Presentation Transcript


Slide 1:Web and Aging — How the Web may evolve to a usable technical artifact as others which we are familiar with —

Hans-Jürgen Hoffmann Darmstadt University of Technology Dept. of Computer Science June 2003 HCI Intl., Crete

Slide 2:Digression to history - Automobile - Telephone - ATM banking Web in history - 1995 minus - 2003 - 2011 plus Some examples of stupid designs Less is more Be positive And an epilogue (if you like)

Slide 3:Remarks from a retired professor in Computer Science Take it easy !

Slide 4:Digression to history — the automobile —

Take Volkswagen as an example Ferdinand Porsche, designing engineer, 1934 High time in the fifties/sixties, millions in use Do you remember: - poor heating - fixed seats - manual choke - frequent checking of oil level - fuel reserve switch at the floor board - manual switching for direction change, no automatic reset Production just stopped in 2003

Slide 5:Digression to history — the telephone —

Philipp Reis, inventor, 1861 Alexander Graham Bell, inventor and designing engineer, 1876 Thomas Alva Edison, inventor, 1876 Long-distance calling, in the fifties Replacement of analogue signalling by digital signalling, ~1990 Internet telephonie, ~2000 Do you remember: - ringing by pulse wheel - operator switching - ground key Largest “computerized” network Easy to use, just lift handset and dial

Slide 6:Digression to history — ATM banking —

Who invented it? Luther George Simjian, 1939 Usable design by Don Wetzel, about 1970 Touch screen, multi-lingual Full service approaching Security features Now nearly everywhere, networked, worldwide Home banking, internet banking Standardisation missing Sorry, I didn’t find a better photography . .

Slide 7:Web in history — 1995 minus —

Hypertext, first approaches beginning 1945 U.S. Defense Advanced Research Projects Agency (DARPA), 1973 - basics of Internet technology Tim Berners-Lee (now Director of the World Wide Web Consortium, W3C), inventor and designing engineer of WWW; prototyping begins about 1990, demonstrations 1991 running Browser development; propagation in science institutes and universities Study Georgia University 1994 http://www.gvu.gatech.edu/user_surveys/survey-01-1994/graphs/results-general.html => 2 % of users elder than 50 years First usability studies and design guidelines in literature (seldom followed)

Slide 8:Web in history — 2003 —

Web is “omnipresent”, like automobile, telephone, ATM Electronic business (B2B), electronic commerce (B2C) Not much advance in usability (although much articles in literature) Elder people on the Web - passive (like TV) - semi-active (surfing for what they are interested in) - active (e.g., contributing in discussing communities) However, (still) low consideration during design for what elder people wish or need, resp.

Slide 9:Web in history — 2011 plus —

Technical restrictions decreasing (e.g., broadband access) and access cheaper Commercialisation Some advance in usability (e.g., “Less is more”-movement) Web even more omnipresent, “mobile” Web: E-Government, E-Learning, E-anything, Virtual travelling, M-Commerce W3C starts to work on usability guidelines for Web usage by elder (and impaired) users Elder people should actively influence Web design and usage — thanks for organising this workshop —

Slide 10:Some examples of stupid designs

Not all (especially elder people) use most recently introduced technologies; incompatibilities Not much emphasis on content Complex, bad arrangements Small font, line thickness, button size, jargon Flashing etc. Who will continue this list ? Similar complaints by other serious Web users !

Slide 11:Less is more (i)

Friedrich Schiller, 1795 - 1805: Einfachheit ist das Resultat der Reife (Simplicity is the result of maturity) Bill Raduchel, ~1999 ( Chief Strategy Officer, Sun Microsystems ) The challenge over the next 20 years will not be speed or cost or performance; it will be a question of complexity Jan Baan, ~1999 Our enemy is complexity, and it’s our goal to kill it Dave Moss, 2001 Keep it simple ( in recognition of Visual Studio.Net, Microsoft Developer Network Journal, issue 27 )

Slide 12:Less is more (ii)

Stickers distributed by an American company, 2000, 2003, ...

Slide 13:Less is more (iii)

There are posters distributed by IBM at CHI 2003 also following the Less is more-movement (sorry, the posters are so big that I can’t scan them in)

Slide 14:Be positive !

However, don’t stop to identify stupid designs ! Say it ! Stupid designs are stupid for all users, not only for the elder people ! Avoid to visit/use them !

Slide 16:Epilogue

That is what we missed ! .

Slide 18:And that is what will come !
