Does changing Fitts’ index of difficulty evoke transitions in movement dynamics?

چکیده
Background: The inverse relationship between movement speed and accuracy in goal-directed aiming is mostly investigated using the classic Fitts’ paradigm. According to Fitts’ law, movement time scales linearly with a single quantity, the index of difficulty (ID), which quantifies task difficulty through the quotient of target width and distance. Fitts’ law remains silent, however, on how ID affects the dynamic and kinematic patterns (i.e., perceptual-motor system’s organization) in goal-directed aiming, a question that is still partially answered only.

متن کاملThe Entropy of a Rapid Aimed Movement: Fitts' Index of Difficulty versus Shannon's Entropy
A thought experiment is proposed that reveals a difference between Fitts’ index of difficulty and Shannon’s entropy, in the quantification of the information content of a series of rapid aimed movements. This implies that the contemporary Shannon formulation of the index of difficulty is similar to, but not identical to, entropy. Preliminary work is reported toward developing a model that resol...
متن کاملOn the Measurement of Movement Difficulty in the Standard Approach to Fitts' Law
Fitts' law is an empirical rule of thumb which predicts the time it takes people, under time pressure, to reach with some pointer a target of width W located at a distance D. It has been traditionally assumed that the predictor of movement time must be some mathematical transform of the quotient of D/W, called the index of difficulty (ID) of the movement task. We ask about the scale of measurem...
متن کاملAugmented feedback influences upper limb reaching movement times but does not explain violations of Fitts' Law
Fitts' (1954) classic theorem asserts that the movement time (MT) of voluntary reaches is determined by amplitude and width requirements (i.e., index of difficulty: ID). Actions associated with equivalent IDs should elicit equivalent MTs regardless of the amplitude and/ or width requirements. However, contemporary research has reported that amplitude-based contributions to IDs yield larger incr...
متن کاملA Literature Survey on Fitts’ Law and its Applications
The way of pointing a target object and the movement time of the pointer lead to a challanging problem in HCI. A large number of seminal paper have been proposed towards this. Moreover, the HCI community uses few formulas, and are related to Fitts’ law. Few are derived from Shannon’s information theory. This paper introduces a survey on Fitts’ law and its derivatives. Finally, we study the vari...
