THIS PROCESS IS REQUIRED FOR YOU TO RECEIVE A GRADE ON THIS QUIZ, even if yоu did а rооm scаn while stаrting, do a 'slow and methodical' scan now: (a) If you use a desktop computer, you must have a 'football size or larger' (about the size of a laptop screen) handheld mirror -- pick up the mirror, hold it at your face level, turn it facing the computer screen, then point it slowly downward toward your work area in front of the computer, hold it for 5 seconds, then slowly point to the right, hold it 5 seconds, the slowly point it toward your left, hold it for 5 seconds, then put it away. (b) If you're using a laptop computer, first tilt the screen down toward your workspace area, hold for 5 seconds, then turn the screen with its camera around, hold it at your face area, and point the computer screen / camera downward toward your work area in front of where the computer usually sits, hold it for 5 seconds, then slowly point to the right, hold it 5 seconds, the slowly point it toward your left, hold it for 5 seconds, then put it away. ONCE YOU COMPLETE THE PROCESS, CLICK True if you did the scan with a laptop, click False if you did it with a mirror. A REMINDER: do the scan slowly enough to clearly show your work environment, since the scan substitutes for a 2-camera set-up. When done, return to your standard testing set-up and continue with the quiz by selecting True as the answer if you did a laptop scan and False if you used a mirror, then keep moving forward.
