- - - - Fovea vision is only a selected area
      - Screens are small
      - Quick movements
  - - - Sensor for yourself
      - As a controller
    - - Top down: controlled voluntarily -> task-driven eye movements
      - Bottom up: eyes drawn towards things, out of our control - > stimulus driven eye movements
  - - - Foveal vision: area that sees HD, colour, detail (high density of cones), the size of a thumb length
      - Everywhere is black and white, fuzzy and sensitive to movement (high density of rods)
      - Further away an item is, the less clear it becomes
      - Blind spot exists
      - Saccades: fastest movements, and we have temporary blindness due to our brain shuting off until our eyes are fixed (fixations) -> spend 3-5 hours/weeks completely blind
      - Eyes select a region instead of a pixel
    - - Gaze =/ touch -> manipulate
