Cross platform

Iterate often: get things out early and often

UI

• UI elements and instruction text have to reference what a user is using

Hardware

• Complexity of project code
• OLED VS LED displays: impact environment and UI design (colors, dithering)
• 3DoF VS 6DoF controllers:

Environments

• One of the biggest challenges for lower-end hardware; designed for 6DoF
• Arc-based teleporting and grid snapping helped make selected seats easier
• Performance remains a challenge
  • PC > 300 draw calls
  • Mobile < 30 draw calls
• Limit mobile users to specific teleport areas to reduce detail
• use unlit shaders to account for battery life considerations

Product

• "What value do we provide for users per platform?"
• Users on high-end devices want to invite friends with mobile
• Distill down to core values to provide the value users want on the application

Avatars

• Avoid full body, since the experience is largely seated
• Eye gazing and blinking eyes are used with a "POI" system to predict and simulate what a users looks at
• "It doesn't have to be realistic, it has to be believable"
• Only render what you know or can easily estimate

Leaning problem

• Linear environments made it impossible for 3DoF users to talk to each other, so curved seats were needed.
