Method for providing three dimensional input and electronic device supporting the same

A method for providing three-dimensional (3D) input by an electronic device, the method comprising:

• generating a first signal by modulating a phase of a default signal using a first code corresponding to a first magnetic field generator connected with the electronic device;
• controlling the first magnetic field generator connected with the electronic device to radiate a magnetic field corresponding to the first signal;
• receiving a signal from at least one sensor connected with the electronic device;
• identifying a second signal corresponding to the first signal from the signal, using the first code;
• and
• determining at least one of a position or a direction of the at least one sensor based on the second signal.

An electronic device comprising:

• a memory;
• and
• at least one processor functionally connected with the memory,
• wherein the at least one processor is configured to:
• generate a plurality of first signals by modulating a phase of a default signal using a plurality of first codes individually corresponding to a plurality of first sensors connected with the electronic device,
• control a magnetic field generator connected with the electronic device to radiate a plurality of magnetic fields corresponding to the plurality of first signals,
• receive a plurality of second signals from the plurality of sensors,
• identify the plurality of second signals using the plurality of first codes, and
• determine at least one of a position or a direction of each of the plurality of sensors based on the plurality of second signals.
