HOW DOES IT WORK?
To make the product work two problems nedeed to be fixed; first how to detect the distance between the two wearables, and secondly, how to detect two hands touching without
a shared ground; the first problem was solved by using two LoRa (long range) transceiver and measuring the RSSI (Received signal strength indication).
The second problem was instead solved by creating a high frequency, around 8Mhz, on the tansmitter, and trough a Filter+Amplifier circuit on the receiver it was
possible to detect the oscillation through the hands of the partecipants when they were touching. The tecnique was largely inspired by Andy Kong's Body Channel Communication Blog,
which was inspired by a Disney Research Paper.
