TechHive.com: If Google Glass isn’t enough to get you worried about technology, how about a device that can see through walls using Wi-Fi?
Researchers at MIT are experimenting with a system called Wi-Vi, which they say can track moving objects through walls by using the inexpensive, nearly ubiquitous wireless system. Wi-Vi could be built into a smartphone or a special handheld device and used in search-and-rescue missions and law enforcement, according to Dina Katabi, the MIT professor who developed Wi-Vi along with graduate student Fadel Adib.
But Katabi thinks consumers might use Wi-Vi, too. For example, someone walking outdoors at night who thought they were being followed might use it to detect a person behind a fence or around a corner, she said.
