A method for determining a displacement of an anchor is provided. The method includes the steps of: determining an initial position of the anchor; and determining a displacement of the anchor. The step of determining the displacement of the anchor includes (i) measuring anchor velocity values, (ii) measuring at least one further physical quantity associated with the anchoring, (iii) deciding whether the anchor is at rest or in motion, wherein a value of the further physical quantity is taken into account in the decision, and (iv) integrating the velocity values over time during intervals when the anchor is deemed to be in motion.

Initiating a communication group of devices using device vibration includes encoding a message into a vibration signal using an encoder in a master device, the message including a connection request. A vibration pattern is emitted 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. A response vibration pattern is received from responding devices using a sensor, the response vibration pattern carrying a response message. The response vibration pattern is decoded with a decoder of the master device to extract the response message from the response vibration pattern. A communication group is established at a host according to the response message for communication between the master device and the responding devices.
