Human Data Bad Target Timing = Poor Target Acquisition Half Speed Lt > 2 s
Human Data Good Target Timing = Fast Target Acquisition Half Speed Lt ~= 0.8 s Also: Good Pursuit Gain!
Human Data Same Patient, Different Pursuit Gains vs. Direction Half Speed Lt > 2 s Bad Pursuit Gain = Poor Target Acquisition
Human Data Eye Switching Contributes to Longer Lt Half Speed Lt ~= 1 s INS + Strabismus = Poorer Target Acquisition
Model Simulation fs Steady-State Error T&R Broadens and Improves NAFX and Lowers Target Acquisition Time Half Speed Lt ~= 1 s Bad Target Timing Still = Poorer Target Acquisition
Fast Target Acquisition, Good Pursuit, VOR, & Eye-Hand Coordination Copper Water Trial 2000 Copper Hunting 2000
T&R means seeing MORE, BETTER, and FASTER, but... Seeing Faster Improves Visual Function and is Necessary for Most Activities in a Full Life I may still miss the bird!
