Multisensory Illusions in
Peripersonal Space Using Tools in
Reality and Virtual Reality

• Peripersonal vs
extrapersonal space
Multisensory Neurons
• Plasticity of
peripersonal
space
• Multisensory neurons
for visual,
somatosensory (touch),
and proprioceptive
stimuli in IPS
• Obayashi et al., 2001
Virtual Reality!

R2 = 0.933
Shrinking Effect?
• Functional site/end effector
• Type of actions and motions afforded by the tool
• No arm represented visually in virtual reality
• High speed and number of stimuli for participants to
respond to during training sessions
Future Studies?
