Method and system for supporting walking in virtual environment

A virtual content execution device comprising:

• a body unit configured to be worn by a user;
• a display unit connected to the body unit and configured to output image information on content;
• and
• a control unit configured to control an output of the image information,
• wherein the body unit is provided with a first bone conduction output unit and a second bone conduction output unit that are disposed on two opposite sides with respect to a specific point of the user, and
• wherein the control unit is configured to:
• analyze, for a sound source of content in a virtual environment, a frequency for a sound band of the sound source;
• separate the sound band of the sound source of the content based on the analyzed frequency and a reference frequency;
• generate, as a first output signal, a sound band having a frequency band smaller than a low band reference frequency of the reference frequency among a whole sound band of the sound source of the content;
• generate, as a second output signal, a sound band having a frequency band greater than a high band reference frequency of the reference frequency among the whole sound band of the sound source of the content, wherein the first output signal and the second output signal are independently generated based on the analyzed frequency;
• and
• output the first output signal and the second output signal at different positions via the first and second bone conduction output unit during execution of the content.

A system for supporting walking in a virtual environment, comprising:

• a content receiving unit configured to receive content;
• a control unit configured to:
• analyze, for a sound source of content in the virtual environment, a frequency for a sound band of the sound source;
• separate the sound band of the sound source of the content based on the analyzed frequency and a reference frequency;
• generate, as a first output signal, a sound band having a frequency band smaller than a low band reference frequency of the reference frequency among a whole sound band of the sound source of the content;
• generate, as a second output signal, a sound band having a frequency band greater than a high band reference frequency of the reference frequency among the whole sound band of the sound source of the content, wherein the first output signal and the second output signal are independently generated based on the analyzed frequency;
• and
• a first bone conduction output unit and a second bone conduction output unit configured to each output the first output signal and the second output signal that have been generated.
