Heather Hopkins Ashley Adams John Sileo I. Describe how the results of this lab compare to Fitts' Law (2pts). Speed and accuracy are the factors that Fitts’ Law uses in certain situations to predict movement time. In our results, the experiment shows that as distance increases and target size decreases which means the Index of Difficulty is increased. The movement time in this experiment increases directly as Index of Difficulty increases. II. Were there systematic differences in the group data between tasks that shared the same ID (i.e., 3a vs. 3b, 4a vs. 4b)? If so, what might these differences indicate, if not what

Unformatted text preview: does this mean (2pts)? In our group there was a systematic difference between the shared IDs. The median numbers of taps for 3a and 3b in our group have a greater distance, than compared to 4a and 4b. The 4a and 4b median is around 3 much less than 3a and 3b. There is not a very big difference between 3a and 4a in this lab experiment. However the 3b and 4b has a greater difference than the 3a and 4a according to the majority of our group. This is what our groups results show for this particular lab experiment....
