Anthony Steed
University College London, London, UK
HITLab, Christchurch, New Zealand
Microsoft Research, Redmond, USA
AI & VR
Steed & Slater
VRAIS 96
Giunchi, James & Steed
Expressive 2018
• Embodiment and how to achieve it
• Cognition and how it should depend on body
schema
• Intention preservation and how this is a social
construct
Why is Virtual Reality Interesting?
Response to Threat
• At a specific time, the
lamp falls over
• The ball and hole have
been pre-cued so that
the hand is in the
region where the lamp
falls
• Looking for a stress
response
Yuan, Steed, et al., 2010
Self-Avatar with gesture

15 seconds 15 seconds 10 seconds 10 seconds 5seconds
(a) (b) (c) (d) (e)

Failures?
• 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
Murcia-Lopez, Steed, 2018
• 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
Solving the Cube
Schroeder, Steed, et al., 2001 (and other papers)

Pan & Steed, 2017
• 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
Thanks
