These are mocks of the interactive shoe in a shop window. using external microphones aimed at the floor it will only react to people walking past the point where the microphone is aimed as i learnt in my experiments using the final project. This is very achievable and low in maintenance for the shop staff. there is no reason for it to be adjusted once its been installed correctly. this is some thing that could have human interaction 24 hours a day. it would arguably be more popular or effective at night time. using a large screen or a back lite projection this could be moved around from shop to shop. a large scale screen would be more suitable for this.
During the forst week of this it would be good to have staff out side giving out flyers or encouraging people to interact but as i have found in my research when one person starts to relise whats happening people usually want to interact or investigate for them selves.
