Track an object through 360 degrees

I would like some advise as to where to start with this idea.

I would like to be able to track the movements of a person running
about in an enclosed area and rotate an object so that it is
constantly facing them.

An example would be a torch mounted on a turntable - as the person ran
about, the torch would always be shining on them.

Requirements are as follows:

The area can measure up to 60 meters x 30 meters.
The tracking device could be placed in the middle or on one side of
the area.
The person would be running about and changing direction.
The tracking device needs to be able to be used indoors and outdoors
(in both artificial and natural light).
If used indoors, the room would have corrugated metal sides.
The person can jump so the height off the ground may change by 2
meters (although I am not interested in tracking the height off the
ground).
It is quite feasible to mount a small lightweight object on the person
to be tracked.
There will be other movement in the area other than that of the object
I wish to track.

I'm unsure as to where to even start with this so any ideas would be
greatly appreciated.

TIA

James.

I used to work here:

http://www.irisys.co.uk

One of the demo systems there used to do something like what you are after.
It would track someone moving about with a motorised CCTV camera on gimbals
and display the image on a monitor.

Or strap the flashlight to their head.

www.wybron.com/Entertainment/Autopilot/

which is an automated tracking followspot system for the entertainment
industry. There are some details of how it works, basically the person
to be tracked wears a radio transmitter, and eight receivers at the
corners of the stage at floor & ceiling level track the position of the
transmitter. Some maths is then used to control robotic lights to point
at the person.
