Theories in Computer human interaction Fitts ’ Law : Modeling Movement Time in HCI

  title={Theories in Computer human interaction Fitts ’ Law : Modeling Movement Time in HCI},
  author={Haixia Zhao},
Fitts' law is a model of human psychomotor behavior developed in 1954 [6]. Extending Shannon’s theorem 17 in information theory (a formulation of effective information capacity of a communication channel), Fitts discovered a formal relationship that models speed/accuracy tradeoffs in rapid, aimed movement (not drawing or writing). According to Fitts’ Law, the time to move and point to a target of width W at a distance A is a logarithmic function of the spatial relative error (A/W), that is [11…

Beyond Fitts' law: models for trajectory-based HCI tasks

A great number of studies have verified and / or applied Fitts' law to HCI problems, making Fitt's' law one of the most intensively studied topic in the HCI literature.

Fitts' law as a performance model in human-computer interaction

Observations support the claim that Fitts' law can model both pointing and dragging operations, even when they occur as a point-select (button-down) action followed by a drag- select ( button-up) action.

Extending Fitts' law to two-dimensional tasks

It is demonstrated that Fitts' law can break down and yield unrealistically low ratings for a task's index of difficulty (ID), and the Shannon formulation is shown to partially correct this problem.

Fitts' Law in two dimensions with hand and head movements.

Two dimensional generalizations of Fitts' Law were discussed in terms of multidimensional scaling and the obtained pattern of movement times was found to be intermediate to the predictions of Euclidean and City-block models of the movement space.

The information capacity of the human motor system in controlling the amplitude of movement.

The motor system in the present case is defined as including the visual and proprioceptive feedback loops that permit S to monitor his own activity, and the information capacity of the motor system is specified by its ability to produce consistently one class of movement from among several alternative movement classes.

Evaluation of mouse, rate-controlled isometric joystick, step keys, and text keys, for text selection on a CRT

Four devices are ev aluated with respect to how ra pid ly they can be used to sc lccl text on a CRT di splay. The mouse is fo und to be fastest on all counts and also to have the lowest error

Human performance using computer input devices in the preferred and non-preferred hands

The experiment shows that the non-preferred hand is more than a poor approximation of the preferred hand, which is well suited for tasks that do not require precise action, such as scrolling.

How does Fitts' law fit pointing and dragging?

The discussion of the results centers around the application of Fitts' Law to pointing and dragging in a point-drag sequence, proposing that the target for pointing is the leftmost edge of the text to be selected, and the targets for dragging is the rightmost edgeof the text.
