The system is very simple: a Hug Shirt™ (Bluetooth with sensors and actuators), a Bluetooth java enabled mobile phone with the HugMe™ java software running (it understands what the sensors are communicating), and on the other side another phone and another shirt. If you do not have a Hug Shirt™ but know that your friend has one you can still send them a hug creating it with the HugMe™ software and it will be delivered to your friend’s Hug Shirt™!
When touching the red areas on your Hug Shirt™ your mobile phone receives the sensors data via Bluetooth (hug pressure, skin temperature, heartbeat rate, time you are hugging for, etc) and then delivers it to the other person.
