Document Summary
3 phases: transport moving toward object, grasp grab onto object, object manipulation making sure you do not drop the object. You start to form your grasp well before you get to the object. Research demonstrating temporal relationship of reach and grasp. Goodale and colleagues: object"s size influences. Timing of max grip aperture (how big your hand opens at widest before grabbing an object) Velocity profile of hand transport movement: regardless of object"s size or distance. Max grip aperture occurs at 2/3 movement time. Which of your senses would be critical to be able to figure out when we should be opening our hand: vision. Preparation and initiation of movement: assesses regulatory conditions. Prehension demonstrates speed-accuracy trade-off characteristics predicted by. Fitts" law: object width = target width. Index of difficulty for grasping containers of different sizes and quantities of liquid: developed by latash and jaric, see a closer look in text.
