Senses and Sensors: Seeing

What would it be like if you could see while walking through a dark room? Or what if you could identify a small object from more than a mile away? Some animals can - like cats and eagles. But people can see better than animals due to the breakthroughs in technology. Using infrared goggles, we can see in the dark, and telescopes help us see as far as the stars. Electric eyes are used to set off burglar alarms, open doors, and turn on lights. Machine vision allows assembly line factories to improve production by using robots. Virtual reality can even simulate an adventure that feels like the real thing. Learn more about seeing in this intriguing book!
