Central only
Conscious
Question- what is it?
What are the 2 different visual systems?
Ambient and focal
What are the 2 visual systems used for?
Object identification
What is the use of focal vision?
Collects information
Relationships between information
Informs the information processing model
What are the 2 types of eye movements?
Smooth tracking
Saccidic
What is smooth tracking?
Reaction time delays
Angular velocity limits
What is saccadic movements?

Saccadic
What are the two visual systems with different processing centres in the brain
Ambient
Focal
What are the functions of ambient vision
Use the whole retina
Central/peripheral
Non-conscious
Question where is it
What are the functions of focal vision
Uses the fovea
Central only
Conscious
Question-what is it
What information does ambient vision provide
Stability, balance, time to contact, direction relevant to other objects
What is optical flow?
Information contained in the optical array and flow across the retina
