Wi-Vi works by sending Wi-Fi radio wave cut through the resistance like wall and measures how it re-reflected. Actually it is almost the same as radar and sonar for how to work however it is small enough and also expensive. Besides, the frequency is limited.

When the signal of Wi-Fi is reflected by an object, the shape and the object arrangement will influence the signal re-reflected. But when the Wi-Fi touch the wall, most of the signal will be reflected on the wall, it is the time when the reflected shadow of someone behind will be seen.
