Fitts''Law Studies of Directional Mouse Movement

  title={Fitts''Law Studies of Directional Mouse Movement},
  author={J. Boritz and K. Booth and W. 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… Expand
Extending Fitts' law to a three-dimensional pointing task.
An attempt was made to extend Fitt's' law to a three-dimensional movement (pointing) task to enhance its predictive performance in this domain and the extended model was shown to better fit the data than the conventional Fitts' model. Expand
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 theExpand
Advanced modeling of selection and steering data: beyond Fitts' law
This work proposes two generalizations of Fitts' law and shows that non-linear transformations on the measured task completion times are indeed advised to resolve problems with the normality and homoscedasticity of the data, especially in case of the tracing task. Expand
Analysis of Mouse Movement Time based on Varying Control to Display Ratios using Fitts'' Law
This paper describes an experiment that attempts to determine what impact different control to display ratios will have on movement time of a mouse in a set of static tasks. The experiment shows thatExpand
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. Expand
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. Expand
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 movementExpand
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.

Fitts’ Law in 3D Space with Coordinated Hand Movements
The study tested the applicability of Fitts’ law to coordinated hand movements in a 3D response space with. An experiment was conducted in which 20 participants performed the Fitts’ pointing tasksExpand


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.

The assessment and analysis of handedness: the Edinburgh inventory.
An inventory of 20 items with a set of instructions and response- and computational-conventions is proposed and the results obtained from a young adult population numbering some 1100 individuals are reported. Expand
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.
