Screens and phones are great constraints for designers, because you have X by Y number of pixels. In VR and AR, the canvas is much bigger and it can be easy to get carried away by thinking, “We could do this, then put that there, and it'll be amazing.” But for users that can be overwhelming. Focus becomes a huge issue. We have to remind ourselves what humans are really good at, and lean into how we actually live and interact with objects. Would this feel right in the real world? Is this believable? Even if it’s fantastical, it should still have a physics engine. Gravity might be turned up way high or way low, but there still needs to be an underpinning framework so people can reason why things are happening around them.
