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
- PsychologyCHI
- 2009
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.

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.

What is a Zero-Difficulty Movement? A Scale of Measurement Issue in Fitts' Law Research
- Computer Science
- 2010
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.
An empirically-derived model for predicting completion time of cursor positioning tasks in dual-task environments

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.

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 information capacity of the human motor system in controlling the amplitude of movement.
- PsychologyJournal of experimental psychology

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.
