Question
Fitts' law Fitts's law (often cited as Fitts' law) is a predictive model of human movement primarily used in human-computer interaction and ergonomics. This scientific law predicts that the time required to rapidly move to a target area is a function of the ratio between the distance to the target and the width of the target[1]. Fitts's law is used to model the act of pointing, either by physically touching an object with a hand.
The metric combines a task's index of difficulty (ID) with the movement time (MT, in seconds) in selecting the target. In Fitts's words, "The average rate of information generated by a series of movements is the average information per movement divided by the time per movement.
the is a figure of fitts' law experiment.
b.write 1 paragraph (>3 sentences) discussing prediction of MT for 4 cm W task.

From the given graph of linear fit, it is clearly seen that the model is not fitted.
i.e.predicted data is not significant with the sample data.
We can say that, Y is dependent on X.
Average time to complete movement is based on the target size(bits).
Experimental data is too much deviating from the model.
Standard deviation is high.
Thank you.
