The ZYTO Scan relies on galvanic skin response (GSR)—an established technology that measures fluctuations in electrical conductivity of the skin. One familiar application of GSR is lie detector testing.
The ZYTO Hand Cradle measures the user’s galvanic skin response and sends that data directly to the ZYTO software for analysis. The GSR data is correlated and compared with Virtual Items in the software database.
Each Virtual Item represents a different physical item. Every time the software introduces a Virtual Item, a corresponding GSR reading is taken by the Hand Cradle. Each new response is measured and tracked in comparison to the GSR baseline reading.
