The user head mounted protection apparatus includes a warning element management device that identifies a warning element by using sensing information generated by sensing a nearby object to generate location information of the warning element, a sensor that detects a rotation of the user head mounted protection apparatus to generate rotation angle information, a corrector that corrects the location information of the warning element by using the rotation angle information, a sound source processor that binaurally renders a sound source by using the location information of the warning element or the corrected location information, and an output device that outputs the binaurally rendered sound source. ## Claims ### Claim 1 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; a sound source processor configured to binaurally render a sound source by using the location information of the warning element or the corrected location information; and an output device configured to output the binaurally rendered sound source. ### Claim 2 (depends on 1) The user head mounted protection apparatus of claim 1, wherein the warning element management device includes: a movement trajectory calculating device configured to calculate a movement trajectory of the nearby object by using the sensing information; a warning element identifying device configured to compare the calculated movement trajectory with a movement trajectory of the user head mounted protection apparatus to determine a possibility of collision between the nearby object and the user head mounted protection apparatus to identify the nearby object as the warning element based on a determination result; and a location information generating device configured to generate location information of the identified warning element. ### Claim 3 (depends on 1) The user head mounted protection apparatus of claim 1, wherein the sensing information includes at least one of image information and radar sensor information. ### Claim 4 (depends on 1) The user head mounted protection apparatus of claim 1, further comprising: a vibration generating device configured to generate a vibration in the user head mounted protection apparatus. ### Claim 5 (depends on 4) The user head mounted protection apparatus of claim 4, wherein the warning element management device compares the location information of the warning element with the rotation angle information after the binaurally rendered sound source is output, and controls the vibration generating device based on a comparison result. ### Claim 6 (depends on 5) The user head mounted protection apparatus of claim 5, wherein the warning element management device controls the vibration generating device to generate a vibration when a difference between a location of the warning element based on the location information of the warning element and a rotation angle of the user head mounted protection apparatus based on the rotation angle information is increased. ### Claim 7 (depends on 1) The user head mounted protection apparatus of claim 1, wherein the warning element management device determines whether the user head mounted protection apparatus and the warning element approach each other by using the location information of the warning element, and wherein the sound source processor increases a volume of the sound source as the user head mounted protection apparatus and the warning element is closer to each other. ### Claim 8 (depends on 1) The user head mounted protection apparatus of claim 1, wherein the output device includes a first output module and a second output module. ### Claim 9 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. ### Claim 10 (depends on 9) The user head mounted protection apparatus of claim 9, wherein the output device includes a third output module, a fourth output module, a fifth output module, and a sixth output module. ### Claim 11 (depends on 10) The user head mounted protection apparatus of claim 10, wherein the third output module, the fourth output module, the fifth output module, and the sixth output module output the sound source at different timings, respectively. ### Claim 12 (depends on 10) The user head mounted protection apparatus of claim 10, wherein the sound source processor time-delays the sound source such that one among the third to sixth output modules, which is closer to a location of the warning element defined based on the location information of the warning element or the corrected location information, or to a corresponding point on the user head mounted protection apparatus than another, outputs the sound source ahead of the another. ### Claim 13 (depends on 10) The user head mounted protection apparatus of claim 10, wherein the sound source processor sets volumes of sound sources output to the third to sixth output modules such that a volume of one among the third to sixth output modules, which is closer to a location of the warning element defined based on the location information of the warning element or the corrected location information, or to a corresponding point on the user head mounted protection apparatus than another, is greater than a volume of the another. ### Claim 14 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.
