Second Level : Mental Immersion / Interactivity of the user

Triadic diagram for the behavioural interfacing

• Desired Behavior... where are the schemas ...
• Effective motor function : what the user will do : Schema, Schema by substitution or Metaphor
• Effective perception : as natural as possible, with as many senses as possible, and as well synchronised (cohering) as possible
• programmed motor function : Behavioural Software Assistance
• Programmed perception : what is available from the virtual world

you may just hear a sound (Schema by substitution) instead of feel the touch of an object
