The invention relates to methods, apparatuses, systems and computer program products for discovery of nearby devices (). To facilitate discovery of nearby, i.e. proximal, devices, a discovery control signal () from a control device () may be used to control the discovery, e.g. how or when the discovery is carried out. The devices may send status information of their status to be used by the control device or the control system for forming the discovery control signal. The control device, e.g. a server, may form the discovery control signal based on this status information. Discovery of proximal devices may then be carried out based on the received discovery control signal.

Discovery method and apparatuses and system for discovery

An example approach for enabling content to be distributed based on user and device related execution criteria is described. A collaboration platform determines one or more execution criteria for at least one device based, at least in part, on presence information, capability information, characteristic information, or a combination thereof of at least one other device within proximity of the at least one device. The collaboration platform also determines an execution of the one or more content items based, at least in part, on one or more execution criteria associated with the one or more content items.

Method and apparatus for distributing collaborative content

A method, apparatus, and computer program product are provided to enable the provision of a mechanism by which a device participating in a collaborative application may synchronize with other participating devices. A method may include providing for operation of a collaboration application, receiving a signal from a sensor, establishing a reference time in response to receiving the signal from the sensor, and synchronizing the collaboration application using the reference time. The sensor may include an accelerometer and the signal may include a sampling of information from the sensor. The sampling may be conducted during a pre-defined time interval or possibly until a bump is detected. Establishing the reference time may include detecting a maximum value of the signal and/or detecting the signal exceeding a pre-defined threshold. Establishing the reference time may not require wireless communication.

Method and apparatus for synchronization of devices

A projector screen includes one or more markers that are configured to be usable by projection processing circuitry in order to calculate a user perceived distortion in an image to be projected on the projector screen.
