The concept of interactivity started to be constituted by interfaces making them adaptable to the relishes, habits and needs of the users. Virtual interface designers who use the opportunities provided by newly developed technological substructures creatively regarding to the needs and expectations of the users developed and put into service the virtual interfaces which can automatically recognize the users and can automatically be personalized in an interactive way. In today''s competitive environment, producers who realized the demand for these virtual interfaces, compete with each other in order to use the concept of interactive personalization to use not only in virtual interfaces but in other products, as well. The expansion of the interactively personalized product design and development of the intelligent building systems supported the usage of interactivity concept in space design. Just like it is in industrially produced but interactively personalized products by using interactive interfaces, spaces can be designed in an interactive personalized way.
