Google Glass function less ' horrible ' ? This technology may make some people more frightened . Because, with this device people can see invisibility .
Scientists from the Massachusetts Institute of Technology ( MIT ) experimented with a system they call the Wi - Vi . The system is able to track objects moving behind the wall , using a wireless system that is relatively cheap and readily available everywhere.
Wi - Vi can be embedded in a smartphone or handheld device specific . Dina Katabi , professor who developed the Wi - Vi with students Fadel Adib said , this system will be used for legal purposes or rescue during natural disasters .
However, according to Katabi , users can use the gadget . For example , when a person is concerned there are follow or stalking from behind , he could use gadgetnya to detect whether or not there are people behind the wall .
For now , Wi - Vi system resolution is still low . As an illustration , the first Wi - Vi version is more like a radar that tracks aircraft , such as the details have not shown the X - ray beam .
Katabi and Adib are working to develop a version with higher resolution , so that the system could recognize faces . But earlier , he said the community needs to have a policy on how to use it . Of course, in order not to shock people and create such concerns when it comes Google Glass .
" As with all the technology in the world , it depends on how we use it , " says Katabi as reported by Computer World , Friday ( 28/06/2014 ) .
Wi - Vi works by sending radio waves Wi-Fi penetrate barriers such as walls , then measure how they bounce back . This is similar to the way radar and sonar , but without the bulky and expensive and limited frequency .
Each time the Wi-Fi signal reflected off an object , shape and composition of the object will affect reflected signal again . However, when Wi - Fi ' bumping ' the wall , most of the signal will be reflected on the wall . That's when the vaguely visible reflections of people who are on the other side of the wall .
