text: One example on how classrooms should be using facial recognition especially with students, can be shown on paragraph #7 whenever the author mentions that home computers can't always rely on facial recongiton, but that school computers can and should. "Your home PC can't handle the complex algorithms used to decode Mona Lisa's smile. But we can write down some simple instructions that "encode" different emotions." As this paragraph is shown to readers, the author is trying to mention a point that home computers can be slow, and may not recognize faces easily, and that right there can lead to stalkers, and hacking occuring as well. Not only that but school computers can get hacked too, but with facial recogonition, they can stop that from happening.
