ASSIGNMENT

• Using the screenshot of graph and table saved by you plot a graph with diameter of target along x-axis and corresponding selection time on y-axis. You will see an inverse relationship between the diameter of the target and the selection time.

• Perform the same experiment using a touchpad on a laptop instead of the mouse. Will use of touchpad on the laptop increase or decrease the target selection difficulty or the slope of the line? Compare your results and graphs.

• You can repeat the same with a touch screen if available. Compare your results and graphs.
