- Consider interaction mechanisms that are better than reality by giving people superhuman powers, rather than applying the universal simulation principle (Chapter 10).
- For locomotion, follow the suggestions in Section 10.2 to reduce vection side effects.
- For manipulation in the virtual world, try to require the user to move as little as possible in the physical world; avoid giving the user a case of gorilla arms (Section 10.3).
- With regard to social interaction, higher degrees of realism are not necessarily better, due to the uncanny valley (Section 10.4).
