Fitts''Law Studies of Directional Mouse Movement

  title={Fitts''Law Studies of Directional Mouse Movement},
  author={James Boritz and Kellogg S. Booth and Wiliam B. Cowan},
An experiment was conducted to test the hypothesis that there is a relationship between the direction of motion (angle) and the time required to move the mouse tracker to a target and that this relationship depends on the handedness of the user. This was done by testing the time required for subjects to perform a target acquisition task similar to item selection ill a pie·shaped menu. Target size. distance and angular placement were varied, with both right handed and left handed subjects tested… 

Fitts' Law in Bivariate Pointing on Large Touch Screens: Age-Differentiated Analysis of Motion Angle Effects on Movement Times and Error Rates

The results reveal that the motion angle has a sinusoidal effect on the movement time for both age groups and practical recommendations where to arrange information elements on large touch screens are given.

Extending Fitts' law to a three-dimensional pointing task.

Extended Fitts' law in Three-Dimensional Pointing Tasks

This study explored an extended three-dimensional Fitts' law that is more suited for the pointing task than the conventional Fitts' law. The experiments were conducted under the manipulation of the

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

Analysis of Mouse Movement Time based on Varying Control to Display Ratios using Fitts'' Law

The experiment shows that an increasing control to display ratio will actually increase the time it takes to perform a given task with a mouse.

The effects of platform motion and target orientation on the performance of trackball manipulation

It is demonstrated that performance of manipulating a trackball is affected by the platform motion and target orientation, which can guide the arrangement of consoles and the design of trackball-based graphical user interfaces on maritime vessels.

Targeted-Tracking With Pointing Devices

A principal component analysis showed that a mouse is relatively superior in terms of both movement time and error rate, indicating that the targeted-tracking model is an effective way to compare and evaluate input devices.


ABSTRACT Numerous studies have found that the performance of manipulating a joystick on input tasks was affected by vehicle motion, and the movement speed of mouse was affected by different movement

Kinematic Analysis of Cursor Trajectories Controlled With a Touchpad

The characteristics of a computer touchpad as a pointing device and the nature of inefficiencies of the touchpad compared with other devices indicate that screen accessibility can vary as a function of users' interaction with cursor controllers and that the default placements of key icons might need to vary.

Extending Fitts' law to account for the effects of movement direction on 2d pointing

The concept of projection is employed to account for the effects of target width and height on movement time so that it can seamlessly integrate the four factors, i.e. Θ, amplitude (A), W and H, into the new extension of Fitts' law, which can uncover not only the periodicity of the asymmetrical impacts of W andH with the variation of Θ but also their interrelation.



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.

An empirical comparison of pie vs. linear menus

Pie menus are a format where the items are placed along the circumference of a circle at equal radial distances from the center where they gain over traditional linear menus by reducing target seek time, lowering error rates by fixing the distance factor and increasing the target size in Fitts's Law.
