Fitts law of movement time
WebLa loi de Fitts est une théorie qui permet de prédire le temps qu’il faudra à un individu pour atteindre une cible en mouvement. Elle est principalement utilisée en ergonomie et en interaction homme-machine [3]. Publiée pour la première fois en 1954 par le psychologue Paul Fitts, elle s’applique à la fois dans le monde […] Webd. movement time Fitts' Law tells us all of the following EXCEPT Select one: a. MT decreases as movement amplitude increases b. MT increases as the target width decreases c. MT increases as the aiming accuracy requirement increases d. None of the above a. MT decreases as movement amplitude increases

WebDec 24, 1999 · Fitts' law states that the movement time (MT) of an aiming movement is a linear function of the index of difficulty (ID), where ID = log2(2A/W, A is the movement amplitude, and W is the target width. This law implies that MT should remain unchanged as long as A/W remains constant (i.e. the absence o … WebSep 5, 2024 · And this Other formula to predict movement time: MT=a+b (ID) MT= Movement time a= intercept from the experiment, and b=slope from the experiment. and ID is once again Index of Difficulty.
