  2. unlikely bed fellows? mobile broadband • different market • different technology • different constraints

  3. ideas! incongruity + analysis = innovation

  4. outline • the past • let it all hang loose • the future • transformative technology • the present • but looking forward

  5. user focus • from want to use the computer • through want to do things using the computer • to want to do things

  6. the past

  7. if a computer were a restaurant • 1960s & early 70s • rather inferior pizza delivery service • late 70s and early 80s • mind your Ps and Qs and stick to the menu • late 80s and 90s • there’s the kitchen, get on with it

  8. interaction focus language command/menu based action GUI interaction?

  9. the screen let it all hang out! don’t think what’s needed? when its needed? just put it all there … … and let the user decide

  10. bandwidth (mobile/broadband difference?) computeruser use screen to trade bandwidth?

  11. trade bandwidth? - NO! information per click ~ log(nos buttons) Fitts’ law - time ~ log(area target/area screen) => input bandwidth approx constant

  12. real screen gains relevant actions - screen changes changing contextual ‘alphabet’ = bigger bandwidth rapid eye movement how much can YOU see? the eye is interactive!

  13. the future

  14. PopuNet everywhere everyone everywhen

  15. products for PopuNet? what are they? … ... I wish I knew! include: • e-shopping (rather than e-buying) • sharing • fun!

  16. everywhere technology - thrift is in space: mobile - small screen TV - use screen for more important  can’t squander screen space time: consumers want to live their lives if it takes time, they won’t do it  can’t squander user’s time

  17. everywhere technology - thrift is in space: can’t squander screen space time: can’t squander user’s time contextual interfaces offering the right thing when its needed

  18. the present understanding context static and dynamic appropriate intelligence

  19. make tea boil kettle brew pour add tea add water static context • understand the task! • traditional task analysis - what is done • now want - what needs to be known

  20. what needs to be known? look at flow chart decision = information need main screen remove user confirm? delete record add user

  21. make tea boil kettle brew pour add tea add water static context • understand the task! • traditional task analysis - what is done • now want - what needs to be known

  22. dynamic context aQtive onCue • watches while the user works context = clipboard • suggests web services • and desktop applications

  23. appropriate intelligence • simple heuristics • right much of the time • valuable when its right • no cost when its wrong!  appropriate interaction e.g. Excel  button, but not …

  24. more ... • me: • cyberspace, mobile etc. http://www.hiraeth.com/alan/topics/ • PopuNet http://www.hiraeth.com/magisoft/PopuNET/ • aQtive: • theoretical background and use in research http://www.aqtive.com/community/research/ • aQtive home (including cracker link) http://www.aqtive.com/
