Touchscreens are rapidly becoming the common user interface 
                          for many public applications such as ATMs, kiosks and 
                          point-of-sale, as they offer an effective and interactive 
                          form of information management. 
                           
                          We have designed and constructed touchscreen presentations 
                          for use at the Royal Show, where users were able to 
                          take themselves through the presentation at their own 
                          pace, going straight to the sections that were relevant 
                          to them. 
                           
                          Evaluation is an essential aspect of producing touchscreen 
                          presentation. Here are a few pointers to successful 
                          use of touchsreen information transfer:
