The system used in Canada (and now being introduced into the UK) by the Terminal/Approach and Towers is a little different to the Australian, where the display screen is a stand alone screen separate from the radar screen (not contained in a window). The input can be mouse or touch screen.
It has it's good and bad points. The down side is that it's not hard (especially when you have fingers like elbows) to to kill a strip unintentionally using the touch screen. And of course, as has happened to me twice now, the system has fallen over, leaving the controller with no flight data input. It is also an adjustment for anyone who has learnt ATC using strips and used to physically moving strips into a sequence order (or throwing at somebody as they walk past............a PC screen is a little on the heavy side)
Up side, with the systems between the Tower and the Terminal units, some verbal co-ordination requrements are reduced. Things like sequence orders, planned low approachs, requested runways, departure orders are displayed. We can also "physically" hand a strip off to the tower for low level VFR arrivals and alike. The system is also linked to the radar such that if a flight plan is entered by a controller into the system through the radar, a "strip" (Or FDE - Flight Data Entry) is created.
