3. Using your prototype image editing interface from the last supervision, consider the task of editing a new photo and sending it to a friend. You may pretend that additional interface options are available if they were not included in your prototype, but they must be in sensible places. i.e. You may not optimise the whole interface around this one task to simplify your answer.
   1. Draw a task flow diagram.
   2. Perform a cognitive walkthrough for this task.
   3. Using GOMS, estimate how long it would take a user to complete the task. Explain your method clearly. Which changes might you consider making to speed up this process?
   4. How might your time estimate be improved using Fitts' and Hick's Laws? Would these be likely to influence your design?
