  1. Hi! I’m Allen.

  2. Picture of SIAT goes here This is where I go to school.

  3. Investigating the Effects of Bimanual Multi-touch Interaction on Creativity • Defended August 12, 2011

  4. Building on Influence of handedness and bilateral eye movements on creativity.Shobe, E. R., Ross, N. M., & Fleck, J. I. (2009).

  5. Bilateral Eye Movement Image from Kawaguchi's Kaishihen(Dissection Notes) 1771

  6. Divergent Thinking and IHI • Task Related Power changes in the EEG alpha band during various creativity tasks. • From Creativity meets neuroscience – Fink et al 2007

  7. Divergent Thinking andAlternate Use scenarios E.g.: You have one minute to come up with as many uses as you can for an everyday object.

  8. Fluency Appropriateness Detail Flexibility(or Categorical Distinctiveness) Originality

  9. What Shobe et al. observed

  10. Does bimanual interaction on a large multitouch display affect divergent thinking in a similar way to bilateral eye movement?

  11. Looks like a job for Science! • Mouse • vs • Unimanual multitouch • vs • Bimanual multitouch

  12. So I built a computerized AUT…

  13. …and I asked 65 participants to carry out the AUT while interacting with the display. 33 female, 32 male, 18 to 50+ years old 22 were assigned to Mouse and Bimanual, 21 to Unimanual 43 Right handers, 5 Left Handers, 17 Ambidextrous 25 self-identified as non-native English speakers

  14. I transformed their spoken responses… Transformed from audio: Totext: You can use it as a tool to scrape or pry; use it as a weapon to stab or scratch; you could again use it as a sort of tooth pick; or as a fastening device with a soft enough other object; you could use it to make designs, like a rule or something, tracing it, use the shape with a pen and paper; or you could kind of wield it like a walking stick or something if it was big enough and you could lean on it; or use it as a support device for some other structure or object. To a list of uses: - a tool to scrape or pry - a weapon to stab or scratch - a sort of tooth pick - a fastening device with a soft enough other object - to make designs, like a ruler, tracing it, use the shape with a pen and paper - wield it like a walking stick if it was big enough and you could lean on it - as a support device for some other structure or object.

  15. Turns out verbal fluency and age have a very strong effect on divergent thinking.

  16. Does bimanual interaction fail to affectIHIlike BEM does?

  17. Does bimanual interaction fail to affectIHIlike BEM does?

  18. Does bimanual interaction fail to affectIHIlike BEM does? Verbal Noise or Display encouraging BEM-like saccades? or _your critique here_

  19. Future Work This work assumes similarity between the paper and computerized AUT in divergent thinking sensitivity– this should be interrogated. Repeat interface style comparison with a more homogeneous participant group Investigate inadvertent IHI via saccades with a different display setup

  20. A More Applied Future? • Start with BFA • Mix in HCI + Cog Psych • ???? • Profit. A thorough examination involves learning more new methods. My MSc took 3 years, and this is just scratching the surface.
