Data transfer between host and peripheral devices

A host computing device comprising:

• a communication interface configured to communicate with a peripheral device comprising an output device;
• and
• a processor configured to:
• monitor a communication link between the host computing device and the peripheral device via the communication interface;
• detect imminent disconnection of communication link based on an identification of a change in operation of the host computing device that precedes the disconnection of the communication link, wherein the change in the operation of the host computing device is identified from at least one of the following:
• change in signal strength of a data connection, change in signal strength of the communication link,
• change in electrical power supply to the peripheral device,
• detection of user touch to the peripheral device, or
• change of position for the peripheral device, wherein the change of position is determined by comparing sensor data from a sensor of the peripheral device and a sensor of the host computing device;
• and
• trigger, in response to detection of the imminent disconnection, a data transfer of output data between the host computing device and the peripheral device via the communication interface, to enable the output data to be received and output at the peripheral device before the disconnection of the communication link, and wherein following the disconnection of the communication link, the output data is fixed in a persistent display state such that the output of the output data at the peripheral device does not change.

A method comprising:

• monitoring a communication link between a first device and a second device;
• detecting imminent disconnection of the communication link based on an identification of a change in operation of either the first device or the second device that precedes the disconnection of the communication link, wherein the change in the operation of either device is identified from at least one of the following:
• change in signal strength of a data connection,
• change in signal strength of the communication link,
• change in electrical power supply to the second device,
• detection of user touch to the second device, or
• change of position for the second device, wherein the change of position is determined by comparing sensor data from a sensor of the second device and a sensor of the first device;
• and
• triggering, in response to detection of the imminent disconnection, a data transfer of output data between a source and destination of the first device and the second device, before the disconnection of the communication of the communication link, and wherein following the disconnection of the communication link, the output data is fixed in a persistent display state at the destination such that the output of the output data at the destination does not change.
