When I showed my grandmother my first virtual reality piece, I didn't know what she'd say. I watched her looking around in the headset, making a small "oh!" when she noticed a woman walking into the scene, or a "hmpf" when she disagreed with a line of dialogue.
When it was over, she took off the headset, looked at me, and said, "It's a good movie Wyatt, but I hate the protagonist."
I was blown away: all the technology, production, and cumbersome gear had melted away. She was left with a story. She didn't happen to think this particular story's characters were very lovable, but her emotional reaction told me I was onto something.
If we can use psychology to nudge people towards better behaviors, if we can craft narratives in new mediums that learn, grow, and develop with the viewer, and if we can build new technology that powers it -- the world may be a much kinder, equitable, sustainable place.
I say "we" because I can't do it alone. If you like making stuff, email me!
