B1.16

Submovement model of target acquisition

Cards in this group · 5

  1. B1.16.1Pointing usually comprises a fast ballistic stroke and slower corrections
  2. B1.16.2Correction count rises with relative ballistic endpoint error
  3. B1.16.3Proportional error reduction per correction yields a logarithmic time relation
  4. B1.16.4Enlarging a target primarily shortens correction, not the ballistic phase
  5. B1.16.5Without visual feedback, correction cannot occur and movement becomes ballistic
