KINE 3020 Midterm: Reading 3: Speed Accuracy
Document Summary
Reading 3: speed accuracy and fitts law: manual aiming skills movement to a target; e. g requires hand to target but at a speed performer determines. Speed-accuracy trade-o trade o speed for accuracy or vice versa i. e emphasis on accuracy will reduce speed or speed = accuracy. D is distance moved: w is target width/ size. As target size or distance = mt to allow accurate movement log2(2d/w) provides index of di culty (id) for speed-accuracy skills. Based original calc on reciprocal tapping task: parbcipants made repebbve back and forth movements as fast as possible btwn two targets for speci c period of bme: motor control processes related to the speed accuracy trade-o . Open loop control inibal movement"s speed, direcbon and accuracy are under cns control. If movement speed is too fast = no su cient bme for visual feedback to adjust movement.
