Sentence examples for index of difficulty from inspiring English sources

Using the Fitts' law, a relation between movement time and index of difficulty was developed for different vibration directions and magnitudes considered in the study.

This is often not the case; where the value of Fitts' Index of Difficulty is low, it is likely that movements will be made ballistically.

The control condition appeared on the computer screen in 70% of the trials, and the other three conditions, (a) distractor, (b) inhibition of response and (c) higher index of difficulty, each appeared in 10% of the trials.

We show that target-acquisition performance in a zooming interface must obey Fitts' law and, more specifically, that target-acquisition time must be proportional to the index of difficulty.

Four amplitudes of movement and 11 values of Fitts' Index of Difficulty (ID) were used to determine conditions under which ballistic movements could be made along with the need for visual control at higher ID values.

For both typically-developed youth and participants with CP, a good model of index of difficulty must include the following predictors: rapidity – movement time, average speed, zero acceleration crossings and accuracy, trajectory distance, linearity index, and indices of vertical and horizontal components.

Indices of difficulty (IDs) were calculated by target sizes and linear distances between targets.

Target width was manipulated with amplitude constant (16°) in order to create indexes of difficulty (ID) of 1.5, 3, 4.5, and 6.

Our first empirical study shows that Fitts' law does apply to a zoomable interface for indices of difficulty up to and beyond 30 bits, whereas classical Fitts' law studies have been confined in the 2 10 bit range.

Distances and size of the two final targets, i.e. their indices of difficulty according to the Fitts' law [1], were the same.

The item analysis was evaluated for the total sample and separately for the individual groups, since from the manner of the construction of the LQPT it was expected that for healthy subjects, higher indices of difficulty would be achieved than was the case for chronically or episodically depressed patients.
