May I get help on this please

Instructions have been prepared for a medical student to perform a surgical procedure on a patient. The instructions are to be presented on an electronic screen. Once the medical student starts working, both her hands will be busy with the tools she'd use. Therefore, she won't be able to interact with the screen. Along with the instructions, live readings of the patient's vitals will also be displayed to the student. There are two possibilities for presenting the information.

One is to have four different screens, cycling after one-another, at a relatively slow rate. The second possibility is to split the screen into four quadrants and present all the information at once. Discuss the advantages and disadvantages of each. What additional information would you need in order to recommend one presentation mode over the other?
