What is the speed-accuracy principle?
-Fitts – came up with a mathematical principle concerning movement speed and accuracy. -Fitts’ Law predicts the movement time for a situation requiring both speed and accuracy in which a person must move to a target as quickly and accurately as possible.
What is an example of speed accuracy trade off?
You have probably experienced speed-accuracy trade-offs many times as you have completed various tasks (Fitts, 1954). For example, you know from experience that the faster you move your computer mouse, the more likely you are to miss the icon you are moving to click.
What is linear speed accuracy trade off?
A linear speed-accuracy trade-off has been found for rapid, precisely timed movements from a home position toward a target point. Instead it supports a temporal-precision hypothesis that the linear trade-off occurs when aimed movements must have precisely specified durations.
What is the speed accuracy trade off in the Fitts law how we can take care of it?
In general, the more accurate the task to be accomplished, the longer it takes, and vice versa. Fitts’ law models the speed- accuracy tradeoff effect in pointing as imposed by the task parameters, through Fitts’ index of difficulty (Id) based on the ratio of the nominal movement distance and the size of the target.
How do you find the inverse efficiency score?
The inverse efficiency score combines speed and error. IES is suggested to be an “observable measure that gauges the average energy consumed by the system over time”. It is calculated by dividing RT by 1 – the proportion of Errors (PE), or the proportion of correct responses (PC).
How does using very forceful movements impact the speed accuracy trade off?
in some cases there are exceptions to the speed accuracy trade off. For example sports that require very forceful movements. when movements are made faster they also influence spatial accuracy. therefore increasing MT increases accuracy.

What is the speed accuracy trade-off in the Fitts law how we can take care of it?
Why are trade-offs unavoidable?
Reduce prices and create jobs. This is the ideal economic outcome expected from all businesses today, not only in the long run, but also in the short term. Generally, lower prices allow more consumers to consume goods or services.
