Abstract
A method for sharing information among multiple devices is provided. The method includes a sensing device sensing signals of at least one object associated with a targeting device and extracting at least one feature of the object from the sensed signals. The method also includes the sensing device broadcasting the extracted feature of the object on a determined network containing a plurality of targeting devices and receiving feedbacks from the plurality of targeting devices on the network in response to the broadcasting. Further, the method includes the sensing device automatically identifying one of the plurality of targeting devices based on the received feedbacks, synchronizing information with the identified targeting device and displaying the information to a user of the sensing device.

A method for sharing information among multiple devices, comprising:
- sensing, by a sensing device, real-time signals of at least one object associated with a targeting device, wherein the at least one object includes real-time media content played back by the target device;
- extracting, by the sensing device, at least one feature of the object from the sensed signals;
- extracting, by the targeting device, at least one feature of the at least one object associated with the targeting device;
- broadcasting, by the sensing device, the extracted feature of the object on a determined network containing a plurality of targeting devices;
- receiving, by the sensing device, feedbacks from the plurality of targeting devices on the network in response to the broadcasting;
- based on the received feedbacks, automatically identifying, by the sensing device, one of the plurality of targeting devices, comprising:
- obtaining corresponding matching scores from the received feedbacks from the plurality of targeting devices;
- determining an identification outcome for each one of the plurality of targeting devices based on the matching scores;
- and
- identifying the one targeting device based on the identification outcome, wherein the identification outcome is defined by:
- H=a*S+(1−a)*f, H is the identification outcome, a is a real number between [0, 1], S is a matching score received from a targeting device, and f is a frequency of the targeting device being identified previously;
- synchronizing, by the sensing device, information with the identified targeting device;
- and
- displaying, by the sensing device, the synchronized information to a user of the sensing device, wherein the synchronized information includes the real-time media content played back by the target device.
