The stripless systems are wonderful for discussion - I've been involved since 1983 so I have a lot of scars! I would suggest that you have a look at
www.eurocontrol.int/hmi. It has some good ideas and gives a reasonable feel for the subject. There will be another web site in a couple of months at
www.ATC-HMI.com where you will see some alternative ideas. Keep the discussion going - it is probably the most important for the controller in the field. Stripless does work if properly designed.
