This is where I go to school.

Investigating the Effects of Bimanual Multi-touch Interaction on Creativity

Defended August 12, 2011

Building on Influence of handedness and bilateral eye movements on creativity.

Shobe, E. R., Ross, N. M., & Fleck, J. I. (2009).

What Shobe et al. observed

Does bimanual interaction on a large multitouch display affect divergent thinking in

a similar way to bilateral eye movement?

Looks like a job for Science!

Unimanual multitouchvs

Bimanual multitouch

So I built a computerized AUT…

…and I asked 65 participants to carry out the AUT while interacting with the display.

33 female, 32 male, 18 to 50+ years old22 were assigned to Mouse and Bimanual,

21 to Unimanual43 Right handers, 5 Left Handers,

17 Ambidextrous25 self-identified as non-native

English speakers

I transformed their spoken responses…

Transformed from audio:To text: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.

To originality and flexibility scores... 975 times.

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

Does bimanual interaction fail to affectIHI like BEM does?

_your critique here_

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

Future Work

A More Applied Future?

1. Start with BFA2. Mix in HCI + Cog Psych3. ????4. Profit.

A thorough examination involves learning more new methods.

My MSc took 3 years, and this is just scratching the surface.
