Prediction of positioning time for auditory target using Fitts' law

Cortical Correlates of Fitts’ Law

Fitts' law describes the fundamental trade-off between movement accuracy and speed: it states that the duration of reaching movements is a function of target size (TS) and distance. While Fitts' law has been extensively studied in ergonomics and has guided the design of human-computer interfaces, there have been few studies on its neuronal correlates. To elucidate sensorimotor cortical activity...

Calculation of Totally Optimized Button Configurations Using Fitts' Law

This paper addresses the problem of optimal placement and configuration for a set of buttons on a graphical user interface (GUI). We present an optimization algorithm that reduces the average time necessary for pointing device motions. Fitts’ law (Fitts 1954) is used to estimate the transfer time for cursor movements between buttons. Numerous studies in the literature focus on the verification ...

One Fitts' Law, Two Metrics

Movement time in Fitts’ law is usually considered through the ambiguous notion of the average of minimum movement times. In this paper, we argue that using two distinct metrics, one relating to minimum time and the other relating to average time can be advantageous. Both metrics have a lot of support from theoretical and empirical perspectives. We also give two examples, one in a controlled exp...

The Optimal Calculation Method to Determine the Effective Target Width for the Application of Fitts' Law

Using Violations of Fitts' Law to Communicate during Joint Action

When people perform joint actions together, task knowledge is sometimes distributed asymmetrically such that one person has information that another person lacks. In such situations, interpersonal action coordination can be achieved if the knowledgeable person modulates basic parameters of her goal-directed actions in a way that provides relevant information to the less knowledgeable partner. W...
