Soon after returning home for break, a
close friend from high school tells you that they have been invited
to invest $2000 in an invention they saw on the Internet. The
invention is a smartphone app called the “Diecorder.” The
Diecorder is a new aid for people on a diet. You simply take a
picture of a plate of food, and it automatically scans it for the
number of calories, grams of fat, and the names and amounts of all
the vitamins contained in the food. Your friend knows that you have
experience with Instrumentation and Measurement and asks you if
they should invest their $2000 in the product. Based on what your
friend has told you about the product, briefly describe what type
of instrument the phone will be using to make the measurement?
Please explain how you arrived at your answer.
