Paper Abstract

Dental medicine needs to observe the motion of the jaw with respect to the skull in three dimensions. This represents, therefore, a problem domain in which one has to observe, in real-time, the motion of one three- dimensional body in 3-D space (the jaw) with respect to another three-dimensional body in 3-D space (the skull) which both may move independently. This paper discusses an innovative solution to this requirement. The solution is implemented on a personal computer and is based on light-emitting diodes that are attached to the two moving 3-D objects. The innovation has been granted patent protection2. An element of the solution is the hand-held 3-D cursor whose position is also trackable as a separate three-dimensional body in 3-D space and allows the user to identify the XYZ coordinates of any point by a free-hand pointing action. Applications of this real-time 3-D measurement system are not only in dental medicine but may extend to mechanical engineering, medical gait analysis and other applications where 3-D motions need to be tracked in real time.
