• Intention preservation and how this is a social
construct

12. • Challenge 1: how to learn about the user to create
an embodiment, visual quality, behavior, gestures,
clothing, belongings
• The brain is highly plastic BUT also very good at
noticing discrepancies
• High individual variance in reaction to self-
representation
14. • Challenge 2: learn how the user interacts with the
world and replace absent cues appropriately.
Dexterity of hands seems to be a specific
challenge
• At the current time, VR is failing to reproduce
certain real-world behaviours
• However, knowledge that something isn’t real
doesn’t necessarily change their behaviour
23. • Challenge 3: intention builds upon knowledge of
the user and is a social construct
• There is complex meaning in collaborative
behaviours, can we interpret it and support it
transparently
