ASW Builder's Fair - Face Mask Detection by AVA

One of the ways to help prevent people from getting sick with COVID-19 is to wear a face mask. In this video, you'll see Ava, a robot created by solutions architects Vikas Shah and Anusha Dharmalingam from Amazon Web Services (AWS), detect whether someone is wearing a face mask. Ava can also tell whether or not the mask is being worn correctly. If something's off, Ava can say where to find a mask and how it should be worn (that is, over both the nose and mouth).

How does Ava work? In the animated explainer that follows the demonstration, you'll learn the answer—it has to do with the concepts of programming and machine learning. Machine learning is where a computer learns tasks by itself based on examples, sort of like getting a sample quiz with the answers to help prepare for an exam. Using the examples, the computer can begin to make guesses—such as whether or not a person's mask is on correctly. This is just one way computers can help people to stay safe. What other ways can you think of?
