How It Works
The "vertical wand" in the Intellifit Virtual Fitting Room™(VFR) contains 196 small antennas that send and receive low power radio waves. In the fifteen seconds it takes for the wand to rotate around a fully clothed individual, the radio waves send and receive low power signals.
The signals don't "see" a customer's clothing but reflect off their skin which is, basically, water. The signals are similar to cell phone signals but less than 1/350th of the power of those signals and they do not penetrate the skin.
When the wand's rotation is complete, Intellifit has recorded over 200,000 points in space, basically x, y, and z coordinates of where that customer is standing. Intellifit software then electronically measures the "point-cloud", producing a file of dozens of accurate body measurements; the raw data is then discarded.
