Question 5
When considering UX/UI, one good rule of thumb to remember with AR is:

1 point

Avoid cluttering the screen with too many buttons or elements that might be confusing to users

Always require designers to create feature points before starting development on your AR app

Avoid thinking about the user flow too much before developing your app as it is important to keep an open mind during the design process
