A method for locating an occupant within an area, the method comprising: receiving a first thermal energy input from the occupant within a first field of view β of a first sensor x1, the first sensor x1 being located at a known location relative to a reference point in the area; receiving a second thermal energy input from the occupant within a second field of view of a second sensor x2 overlapping the first field of view, the second sensor x2 being located at a second known location relative to the reference point in the area; determining a first distance L1 from the occupant to the first sensor xl based on the first thermal energy input received by the first sensor x1 and the location of the first sensor x1; determining a second distance L2 from the occupant to the second sensor x2 based on the second thermal energy input received by the second sensor x2 and the location of the second sensor x2; and determining a coordinate position of the occupant in the area relative to the reference point based on the determined first distance L1 and the determined second distance L2; characterized in that the first thermal energy input is received by at least one pixel in a first plurality of pixels of the first sensor x1; and the second thermal energy input is received by at least one pixel in a second plurality of pixels of the second sensor x2; and wherein determining the first distance L1 from the occupant to the first sensor x1 further includes determining an azimuth angle ξ between a reference axis and a line of sight from the first sensor x1 to the occupant based on: a field of view β of the first sensor xl; a field of view of a pixel γ of the first plurality of pixels of the first sensor xl; and a pixel number n associated with the pixel in the first plurality of pixels; wherein a field of view is an angle through which a sensor or a pixel can receive a thermal energy input; and wherein said azimuth angle ξ of the first sensor x1 is determined according to the equation: ξ x 1 = 90 ° − β x 1 2 + n x 1 γ x 1. receiving a first thermal energy input from the occupant within a first field of view β of a first sensor x1, the first sensor x1 being located at a known location relative to a reference point in the area; receiving a second thermal energy input from the occupant within a second field of view of a second sensor x2 overlapping the first field of view, the second sensor x2 being located at a second known location relative to the reference point in the area; determining a first distance L1 from the occupant to the first sensor xl based on the first thermal energy input received by the first sensor x1 and the location of the first sensor x1; determining a second distance L2 from the occupant to the second sensor x2 based on the second thermal energy input received by the second sensor x2 and the location of the second sensor x2; and determining a coordinate position of the occupant in the area relative to the reference point based on the determined first distance L1 and the determined second distance L2; characterized in that the first thermal energy input is received by at least one pixel in a first plurality of pixels of the first sensor x1; and the second thermal energy input is received by at least one pixel in a second plurality of pixels of the second sensor x2; and wherein determining the first distance L1 from the occupant to the first sensor x1 further includes determining an azimuth angle ξ between a reference axis and a line of sight from the first sensor x1 to the occupant based on: a field of view β of the first sensor xl; a field of view of a pixel γ of the first plurality of pixels of the first sensor xl; and a pixel number n associated with the pixel in the first plurality of pixels; wherein a field of view is an angle through which a sensor or a pixel can receive a thermal energy input; and a field of view β of the first sensor xl; a field of view of a pixel γ of the first plurality of pixels of the first sensor xl; and a pixel number n associated with the pixel in the first plurality of pixels; wherein a field of view is an angle through which a sensor or a pixel can receive a thermal energy input; and wherein said azimuth angle ξ of the first sensor x1 is determined according to the equation: ξ x 1 = 90 ° − β x 1 2 + n x 1 γ x 1.
