I am building a project where I need to detect the presence and
position of a person standing in front of a sensor.  It does not need
to be accurate; I just want to know within say, 5 degrees, where the
person is standing in front of my device.  There will be no other
objects near the person and the person will be between 2 and 7 feet
away.  

Any ideas??  Is there an "off the shelf" way, or some sort of a
"standard" strategy?  I definitely want to minimize space, weight, and
$.  

I would be really grateful for any help.  Thanks in advance.
