Self-motion illusion induction system
KiNvis

A system that induces the illusion of movement in the paralyzed side of a hemiplegic patient or in the upper limbs with reduced sensory and motor function.

KiNesthetic illusion induced by visual stimulation
"KiNvis" realizes a "visually induced self-motion illusion."

Self-motion illusion is a sensation that one's own limbs are moving, even though no joint movement is occurring.

Here are the main features

Effects of self-motion illusion on the body

・The video of the healthy side's movements is played in reverse on the upper part of the paralyzed side, creating the illusion that the paralyzed hand is moving, generating motor intentions
・Induces a sense of body ownership and agency on the paralyzed side
・In cases where skin sensation remains, combining it with tactile stimulation increases the sensory immersion effect (ownership)

Brain activity caused by self-motion illusion

・Kinesthetic illusions activate neural circuits in the brain involved in the expression of movement.
・Self-motion illusions increase excitability of the corticospinal pathway

Features of KiNvis

・Safe design with no moving parts
・Software with an interactive GUI for easy clinical use
・Induces learning based on Hebb's law by synchronizing with external devices
