Dilemma
Technology
evolution goes
through 3 stages.

1. Horse & Buggy
2. Horseless
Carriage
3. True Automobile

Pairing a console
game controller &
UI with a VR HMD
feels like a slapping
transparent D-Pad
on an iPhone game
øDisruptive technologies typically enable new markets to emerge.
Clayton M. Christensen, The Innovator’s Dilemma

XEODesign
VR Needs Innovation Tools
Ø No one knows what they are doing
Ø Just try to see what works
Ø Everything is different
Ø Presence / Empathy
Instead we need first principles
How to think like a VR designer
How to make it feel like Wonderland
“That doesn’t work in VR” often means that it’s hard or it’s new

Ø Follow Camera
(God Cam Instead)
A follow camera on
a diagonal jumping
puzzles is one of
the hardest things
to do well in VR
because it involves
forward, sideways,
and vertical motion
compounded by
camera motion.
None of these
motions are felt by
the player.
Unfortunately.

HUD = Depth
Part of Tilt Brush’s
appeal is the sense

creating a world

Build the world

rather than navigate

well in VR.

Emotion Solves VR’s Challenges
Emotion is a Design Tool. Emotions solve VR / AR’s biggest challenges.
Desire to
Return
Emotions make an
experience more
memorable and desirable.
Have Fun
Without emotion there is no fun.
Create Social
Emotions
People play games to spend
time with their friends. Social
emotions make players feel
more connected in VR / AR.
Direct Attention
Emotions focus players and help
them follow along without the
camera framing the action.
Increase Comfort
Strong emotions (the right kind)
change players’ physiology
to increase comfort.
Create Haptics
Without a suit and gloves.
Port Gameplay
Provide fun of popular genres
within VR / AR’s constraints.

In VR, although
headphones are

decreases

than increases it.

This is the opposite
