POOH should determine the angle, in degrees, formed by north, the beacon, and the device, in a clockwise direction. For example, if POOH indicates 90 then the user is east of the beacon. 1 The beacon consists of a light surrounded by a non-dispersing gradient filter, which works as follows: The filter is transparent to light at a wavelength of 500 nm. The filter is positioned around the light so that for light at a wavelength of 700 nm the filter varies linearly from completely transparent, at an angle of 0 to completely opaque just before angle 360 .( A sw i
