Division of Labor Between Eye and Head

Cards in this group · 4

  1. C8.12.1Eyes move fast over small amplitudes for fine pointing; the head moves slowly over large amplitudes for coarse aiming
  2. C8.12.2Eyes and head often desynchronize; gaze target and head orientation can separate
  3. C8.12.3When combined, the head typically sets overall orientation and the eyes fine-tune within it
  4. C8.12.4Head-dependent schemes fail for users with limited neck mobility and need an eye-only path
