Connection between 3D engine unity and microcontroller arduino: A virtual smart house

Nowadays, virtual tours are very popular and many people would like to see a virtual house before the acquisition of the real one. The paper demonstrates a creation of a virtual tour for smart home developed in Unity 3D engine. This virtual tour is connected with Arduino microcontroller which has attached several sensors and actuators. These electronic devices react to the events in the virtual tour and vice versa.
