Another application for real-time tracking is augmented reality.
In this work, we add computer graphics to a user's view of the world
via a see-through heads-up display. To do this, it is necessary to
know the location of the user's head at all times, so that the
graphics can be correctly registered with the objects in the real
world that they refer to. This is achieved by mounting a video camera
on the headset, together with three MEMS rate gyroscopes to give
robustness to large transient head motions.
Movies
All of these movies have been filmed by mounting a camcorder where the
user's left eye should be, so they show a view of the world through
the headset. All of the real objects that can be seen in the movies
can really be seen by the camcorder, while all the computer graphics
are generated by a computer in real-time and superimposed over the
real world using the headset.

a longer demo made in our machine
room This is a fairly conventional maintenance/navigation
application. Near the beginning, the system is shaken violently to
show robustness to sudden rapid motion - and then there's a twist.
