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

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

Divergent Thinking and IHI

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

What Shobe et al. observed

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

So I built a computerized AUT…
![Page 13: Hi!](https://reader035.vdocuments.us/reader035/viewer/2022070422/568163ea550346895dd55ed8/html5/thumbnails/13.jpg)
…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

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?

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

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.
