Characterizing non-visual target acquisition tasks with the aid of a tactile display: investigating factors beyond the classical Fitts’ theorem

The results show that Fitts’ law accurately predicts performance for the visually impaired, even though the average movement time exceeded the 3-s window typical of rapid-aimed movement, and a model to predict overall MT in non-visual environments with the aid of haptic reference points is proposed.

The Reliability of Fitts’s Law as a Movement Model for People with and without Limited Fine Motor Function

Fitts’s law should be used with caution and, if possible, over multiple sessions, especially when used in assistive technology evaluations, suggesting that Fitts's law provides low test-retest reliability.

Advanced modeling of selection and steering data: beyond Fitts' law

Issues Related to HCI Application of Fitts's Law

Although varied target conditions led to longer movement times, the effect was additive, was surprisingly small, and did not depend on whether the movements were discrete or serial, which suggests that evaluating devices or designs using blocked data may be acceptable.

The problem of consistency in the design of Fitts' law experiments: consider either target distance and width or movement form and scale

In most cases eliminating one factor will allow a safer estimation of Fitts' law parameters, while simplifying the experimental work, and the paper ends up with practical recommendations for the design of consistent Fitt's' law experiments.

Behind Fitts' law: kinematic patterns in goal-directed movements

Fitts' Throughput and the Remarkable Case of Touch-Based Target Selection

The method of calculating Fitts’ throughput is detailed, considering task characteristics, the speed-accuracy trade-off, data collection, and data aggregation, and the distinction between indirect and direct pointing devices is elaborated using the examples of a mouse as an indirect pointing device and a finger as a direct pointing device.

On the Limits of the Human Motor Control Precision: The Search for a Device's Human Resolution

The concept of a Device's Human Resolution (DHR) is introduced: the smallest target size that users can acquire with an ordinary amount of effort using one particular device.

What is a Zero-Difficulty Movement? A Scale of Measurement Issue in Fitts' Law Research

It is shown that the two most popular versions of the ID, the original Fitts ID and the Shannon ID, lack a true physical zero, meaning that their measurement runs on a non-ratio equal-interval scale and that Fitt's' paradigm has been under-constrained so far from the measurement viewpoint.

According to Fitts' law, human movement can be modeled by analogy to the transmission of information. Fitts' popular model has been widely adopted in numerous research areas, including kinematics,…

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.

Testing pointing device performance and user assessment with the ISO 9241, Part 9 standard

This paper evaluates the scientific validity and practicality of these dimensions for two pointing devices for laptop computers, a finger-controlled isometric joystick and atouchpad, and a discussion of problems in implementing the IS0 standard and recommendations for improvement.

More than dotting the i's --- foundations for crossing-based interfaces

This paper systematically evaluates two target-pointing tasks and four goal-crossing tasks, which differ by the direction of the movement variability constraint (collinear vs. orthogonal) and by the nature of the action (pointing vs. crossing, discrete vs. continuous).

The “prince” technique: Fitts' law and selection using area cursors

It is shown that selection in such cases can be facilitated if the cursor is an area, rather than a point, and that Fitts' law still holds when the target is a point and the width of the mouse cursor is W.

Movement model, hits distribution and learning in virtual keyboarding

Increased visual load when typing previously practiced text did not significantly change users' performance at this stage of learning, but typing unpracticed text did have a performance effect, suggesting a certain degree of text specific learning when typing on virtual keyboards.

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.
