Reducing the Gesture Set for Ventana

Ventana was designed to be used without any learning time. Therefore I had to use a gesture set which had to be reduced to only a few possibles. It should be easy for nearly everybody to use.

Currently there are two possible ways to control the application.One is the bare presence and one is hand pointing gesture. It was an important aspect for me to make sure that the users do not feel silly when using the shop window in public space. Having a reduced gesture set makes it easy for people to learn how to control the system.
