<p><b>New page</b></p><div>An '''ultrasonic tracking system''' is a 3D tracking system that uses ultrasonic sound. It may do multilateration. It may use the Kabsch algorithm to do [[point-set registration]].<br />
<br />
It may be used, for example, in an [[AR glasses]] system to track the [[position and orientation]] of the glasses.<br />
<br />
It needs a line of sight (auditory sight), which is a line of unimpeded travel between source and sensor.<br />
<br />
[[Ivan Sutherland]]'s report on the ultrasonic positioning system used with his 3D display did not mention any use of the Kabsch algorithm.<ref name="j688">{{cite conference | last=Sutherland | first=Ivan E. | title=A head-mounted three dimensional display | publisher=ACM Press | date=1968 | doi=10.1145/1476589.1476686 | page=757}}</ref><br />
