From the above plot, we can observe that speed to hit the target ‘S’ is indicated by ‘1/b’ (inverse of slope of Linear or Best Fit line). Hence, the speed is

Speed (S) = 1/b

= 1/49.3 = 20 Hz (when the time converted to seconds)

Also at Index of Difficulty ‘3.1’ this represents the farthest distance. At this point users are taking highest time (1900 msec) to hit the target.

From the above plot, we can observe that speed to hit the target ‘S’ is indicated by ‘1/b’ (inverse of slope of Linear or Best Fit line). Hence, the speed is

Speed (S) = 1/b

= 1/71.4 = 14 Hz (when the time converted to seconds).

Also at Index of Difficulty ‘3.1’ this represents the farthest distance. At this point users are taking highest time (1600 msec) to hit the target.

When we analyze the experimental results of both the directions, we get to know that Speed to hit the target is high when the target circles are left side of the screen.

From the above inference our experimental results matches with the predicted results in terms of direction. i.e. Users with right handed habitual will take less time to move towards the left side of the screen than towards right side. Due to the reason that 90% of our sample users are right handers, our experimental results show the same inference.

From the above plot, we can observe that speed to hit the target ‘S’ is indicated by ‘1/b’ (inverse of slope of Linear or Best Fit line). Hence, the speed is

Speed (S) =
