Abstract

Disclosed herein are a user terminal for performing mutual awareness with an awareness target terminal located within a preset distance and a method for performing mutual awareness between a user terminal and an awareness target terminal located within a preset distance. The user terminal includes a signal generation unit and a magnetic field formation unit. The signal generation unit generates pulse signals. The magnetic field formation unit generates magnetic fields that correspond to the pulse signals and that generate induced currents in the awareness target terminal.

Claims

1. A user terminal for performing mutual awareness with an awareness target terminal located within a preset distance, comprising:

a signal generation unit configured to generate pulse signals; and

a magnetic field formation unit configured to generate magnetic fields that correspond to the pulse signals and that generate induced currents in the awareness target terminal.

2. The user terminal of claim 1, further comprising a determination unit configured to determine a location of the awareness target terminal based on the induced currents when the induced currents flow through the field formation unit of the user terminal in response to the magnetic fields that are generated in the awareness target terminal.

3. The user terminal of claim 2, wherein the magnetic field formation unit comprises a first electric coil that is disposed on a first surface of the user terminal to be spaced.

4. The user terminal of claim 3, wherein the magnetic field formation unit further comprises a second electric coil that is disposed on a second surface of the user terminal to be spaced, the second surface being opposite the first surface.

5. The user terminal of claim 4, wherein the magnetic field formation unit further comprises a third electric coil that is disposed on a third surface of the user terminal to be spaced, the third surface connecting one end of the first surface with one end of the second surface.

6. The user terminal of claim 5, wherein the magnetic field formation unit further comprises a fourth electric coil that is disposed on a fourth surface to be spaced, the fourth surface being opposite the third surface.

7. The user terminal of claim 6, wherein the signal generation unit transmits different pulse signals to one or more of first, second, third and fourth electric coils, and the first, second, third and fourth electric coils generate different magnetic fields in response to the different pulse signals.

8. A method for performing mutual awareness between a user terminal and an awareness target terminal located within a preset distance, comprising:

generating, by a signal generation unit of the user terminal, pulse signals; and

generating, by a magnetic field formation unit of the user terminal, magnetic fields that correspond to the pulse signals and that generate induced currents in the awareness target terminal.

9. The method of claim 8, further comprising determining, by a determination unit of the awareness target terminal, a location of the user terminal based on the induced currents when the induced currents flow through a field formation unit of the awareness target terminal in response to the magnetic fields that are generated upon generating the magnetic fields.

10. The method of claim 9, wherein generating the magnetic fields comprises generating the magnetic fields using the magnetic field formation unit that comprises a first electric coil that is disposed on a first surface of the user terminal to be spaced.

11. The method of claim 10, wherein generating the magnetic fields comprises generating the magnetic fields using the magnetic field formation unit that further comprises a second electric coil that is disposed on a second surface of the user terminal to be spaced, the second surface being opposite the first surface.

12. The method of claim 11, wherein generating the magnetic fields comprises generating the magnetic fields using the magnetic field formation unit that further comprises a third electric coil that is disposed on a third surface of the user terminal to be spaced, the third surface connecting one end of the first surface with one end of the second surface.

13. The method of claim 12, wherein generating the magnetic fields comprises generating the magnetic fields using the magnetic field formation unit that further comprises a fourth electric coil that is disposed on a fourth surface of the user terminal to be spaced, the fourth surface being opposite the third surface.

14. The method of claim 13, wherein:

generating the pulse signals comprises transmitting different pulse signals to one or more of first, second, third and fourth electric coils; and

generating the magnetic fields comprises generating, by the first, second, third and fourth electric coils, the different magnetic fields in response to the different pulse signals.
