Creating a social group with mobile phone vibration

A method for initiating a communication group of devices using device vibration, the method comprising:

• encoding a message into a vibration signal using an encoder in a master device, the message including a connection request and a request key;
• emitting a vibration pattern using a vibration motor by controlling the vibration motor to vibrate with a pattern corresponding to modulations of the vibration signal to send the message through a medium in contact with the master device;
• receiving a response vibration pattern from at least one responding device in contact with the medium using a sensor, the response vibration pattern carrying a response message including an acknowledgment key;
• decoding the response vibration pattern with a decoder of the master device to extract the response message from the response vibration pattern;
• comparing the request key and the acknowledgment key to determine a match;
• authorizing the at least one responding device according to the match;
• and
• establishing a group chat at a host, the host being the master device according to the response message for communication between the master device and the at least one responding device.
