Interactive architecture refers to the branch of architecture which deals with buildings featuring the trio of sensors, processors and effectors, embedded as a core part of its nature and functioning. Interactive architecture encompasses building automation but goes beyond it by including forms of interaction engagements and responses that may lay in pure communication purposes as well as in the emotive and artistic realm, thus entering the field of Interactive art . Interactive architecture part of the Internet of things , a term first coined by Kevin Ashton of Procter & Gamble, later MIT's Auto-ID Center, in 1999 , can include both interior and exterior elements. Within the interior, many technologies are competing to see who will emerge as the dominant communicative signal. 4GLTE LTE (telecommunication) being replaced eventually by 5G , is the obvious solution, however Visible light communication or Li-Fi , a term first introduced by Harald Haas during a 2011 TEDGlobal talk in Edinburgh , is gaining ground as research into this type of data transfer method increases. Interactive architecture and designing our buildings with this technology embedded in it, is essential in the development of smart cities .
