Identification of proximate devices
A method of identifying proximate client devices ( 1, 2 ) comprises the steps of: providing a sensory identifier, the first device ( 1 ) detecting the sensory identifier and sending a first request message (RQ 1 ) comprising a first representation of the sensory identifier to a matching unit which is preferably part of a correlation server ( 5 ), the second device ( 2 ) detecting the sensory identifier and sending a second request message (RQ 2 ) comprising a second representation of the sensory identifier to the matching unit, and the matching unit comparing the first representation and the second representation and sending an acknowledgement message (AC 1 , AC 2 ) to each of the first device ( 1 ) and the second device ( 2 ) if a match is made. Each request message (RQ 1 , RQ 2 ) contains a pointer to at least one property of the respective device ( 1, 2 ). In addition, the matching unit applies matching rules relating to the properties to limit the number of possible matches.
1. A method of identifying proximate devices, the method comprising the steps of:
providing a sensory identifier capable of being detected by human senses,
detecting, by a first device, the sensory identifier and sending a first request message to a matching unit, the first request message comprising a first representation of the sensory identifier and at least one of a first property of the first device indicating whether a predetermined game is loaded onto the first device or a pointer to the first property,
detecting, by a second device, the sensory identifier and sending a second request message to the matching unit, the second request message comprising a second representation of the sensory identifier and at least one of a second property of the second device indicating whether the predetermined game is loaded onto the second device or a pointer to the second property,
the matching unit comparing the first representation and the second representation and sending an acknowledgement message to each the first device and the second device if a match is made, the matching unit applying matching rules to limit the number of possible matches if the comparing results in making a match, the matching unit applying the matching rules to the first property and the second property comprised in or pointed at in the first request message and the second request message,
the first device and the second device being configured to establish contact and start the game after identifying each other based on an acknowledgment message received from the matching unit.
2. A computer program product stored on a non-transitory computer-readable storage medium for carrying out the method according to claim 1 .
3. A matching unit for matching proximate devices, wherein each of the proximate devices has detected a sensory identifier capable of being detected by human senses and has sent a respective request message to the matching unit, the request message comprising a respective representation of the sensory identifier detected by the each of the proximate devices and at least one of a property of the each of the proximate devices or a pointer to the property, the matching unit being arranged for:
comparing the first representation and the second representation from the request messages of a first device and a second device of the devices and
sending an acknowledgement message to each of the first device and the second device if a match is made, and
applying matching rules relating to the properties of the respective proximate devices comprised in or pointed to in the request messages to limit the number of possible matches if the comparing results in making a match,
the first device and the second device being configured to establish contact and start the game after identifying each other based on an acknowledgment message received from the matching unit.
4. The matching unit according to claim 3 , wherein the pointer to the property is constituted by the property itself and/or is constituted by a device identification which allows the matching unit to retrieve the respective property.
5. The matching unit according to claim 3 , further provided with an expert system for adjusting the rules in dependence on matches made.
