User head mounted protection apparatus and method of operating same

A user head mounted protection apparatus comprising:

• a warning element management device configured to identify a warning element by using sensing information generated by sensing a nearby object to generate location information of the warning element;
• a sensor configured to detect a rotation of the user head mounted protection apparatus to generate rotation angle information;
• a corrector configured to correct the location information of the warning element by using the rotation angle information;
• an output device configured to output a sound source through a plurality of channels;
• and
• a sound source processor configured to time delay the sound source by using the location information of the warning element or the corrected location information such that the sound source is output with different delay times through the plurality of channels.

A method of operating a user head mounted protection apparatus, the method comprising:

• identifying a warning element by using sensing information generated by sensing a nearby object;
• generating location information of the warning element;
• sensing a rotation of the user head mounted protection apparatus to generate rotation angle information;
• correcting the location information of the warning element by using the rotation angle information;
• time-delaying a sound source by using the location information of the warning element or the corrected location information such that sound sources output through the plurality of channels have different delay times;
• and
• outputting the time delayed sound sources.
