Abstract
A terminal and method for recognizing a communication target within a visible range. The method of a terminal to recognize a communication target includes obtaining location information of a communication target whose identification information is unknown within a visible range of a terminal user; and recognizing a relative location of the communication target with respect to the terminal based on the obtained location information and displaying the recognized relative location of the communication target.
Claims20
A method of a terminal to recognize a communication target, comprising:
- obtaining location information of a communication target which is located within a visible range of a terminal user and whose identification information is unknown;
- and
- recognizing a relative location of the communication target with respect to the terminal based on the obtained location information and displaying the recognized relative location of the communication target,
- wherein the displaying of the recognized relative location of the communication target comprises calculating relative angle θa′ of the communication target,
- wherein the relative angle θa′ is calculated by subtracting a difference between an orientation angle γ, which is between a reference direction of the terminal and a direction to which the terminal is directed, and an orientation angle λ/2, which is between the direction to which the terminal is directed and a boundary of a field of view of the user, from a respective orientation angle θa, which is between the reference direction and the direction to which the communication target is directed.

A method of a terminal to recognize a communication target, comprising:
- acquiring an image of the communication target which is located within a visible range of a terminal user and whose identification information is unknown;
- obtaining orientation information of the terminal including a direction and an orientation angle of the terminal;
- issuing a location information request to the communication target and receiving location information of the communication target as a response;
- and
- recognizing a relative location of the communication target using the orientation information of the terminal and the location information of the communication target, mapping the recognized relative location of the communication target to the acquired image of the communication target, and displaying the mapping result on a screen of the terminal,
- wherein displaying the mapping result of mapping the recognized relative location of the communication target comprises calculating relative angle θa′ of the communication target,
- wherein the relative angle θa′ is calculated by subtracting a difference between an orientation angle γ, which is between a reference direction of the terminal and a direction to which the terminal is directed, and an orientation angle λ/2, which is between the direction to which the terminal is directed and a boundary of a field of view of the user, from a respective orientation angle θa, which is between the reference direction and the direction to which the communication target is directed.

A terminal comprising:
- a sensor configured to acquire orientation information including a direction and an orientation angle of the terminal;
- a communication unit configured to issue a request for location information to a communication target which is located within a visible range of a terminal user and whose identification information is unknown and receive the location information from the communication target;
- a control unit configured to recognize a relative location of the communication target using the orientation information of the terminal and the location information of the is communication target and map the recognized relative location of the communication target in a screen of the terminal;
- and
- an output unit configured to display the mapped relative location of the communication target on the screen,
- wherein to display the recognized relative location of the communication target, a relative angle θa′ of the communication target is calculated,
- wherein the relative angle θa′ is calculated by subtracting a difference between an orientation angle γ, which is between a reference direction of the terminal and a direction to which the terminal is directed, and an orientation angle λ/2, which is between the direction to which the terminal is directed and a boundary of a field of view of the user, from a respective orientation angle θa, which is between the reference direction and the direction to which the communication target is directed.
