Patent ID: 8433759

Claim:
A method of direction-conscious information sharing, the method comprising: receiving user input at a sender device, the user input specifying information to be shared and a direction relative to the sender device; executing instructions stored in memory, wherein execution of the instructions by a processor identifies a recipient device located in a target area, the target area being defined based on the specified direction relative to the sender device; and sending the specified information to the recipient device, including data to allow the recipient device to generate a notification indicating a direction of the sender device relative to the recipient device, wherein indicating a direction of the sender device relative to the recipient device includes: defining a first angle between a vector pointing from the sender device and a vector pointing to the recipient device from the sender device, defining a second angle between a vector pointing from the recipient device and a vector pointing in a direction in which the recipient device is oriented, determining a third angle by subtracting the first angle from 180° and adding the second angle, and determining the direction of the sender device relative to the recipient device based on measuring the third angle from the vector pointing in the direction in which the recipient device is oriented.
