Patent ID: 8840013

Claim:
A portable computing device comprising: a display; a detection device; a transmission device; memory for storing instructions that are executable by processor electronics; processor electronics configured to execute the instructions in order to: detect a first signal from a reader in response to the computing device entering a specific geolocation; in response to detection of the first signal, recall content from the memory and display the content on the display as well as transmit a reference to an identity of the content to the reader, wherein the reference to the identity of the content is configured to be added to a user profile; detect a second signal from the reader produced when the reader detects the content reference transmission; recall other content from the memory for display and transmit a reference to an identity of the other content upon detection of the second signal from the reader; and associate the computing device with the user profile, wherein the user profile is comprised of at least; 1) a user characteristic; and 2) a statistical probability associated with said user characteristic, said user characteristic and statistical probability based at least upon a user content affinity input and a reference to an identity of content transmitted from the computing device, wherein the user characteristic and statistical probability are configurable as components in an interest graph in which the user characteristic is represented as an interest graph node and the statistical probability is represented as an interest graph link connecting the interest graph node to another interest graph node.
