This thesis was commissioned by Nokia. The aim of this thesis was to define interfaces between a real and virtual world, find different ways to give a user input to virtual reality and determine what kind of feedback can be provided from physical devices to virtual reality. As a practical implementation, a virtual reality control system was created for the base station testing laboratory.

The virtual reality application in the practical implementation was created on top of Unity Engine. SteamVR was used as a programming interface to virtual reality hardware. All the needed 3D models were designed using Blender.

As a result, a fully working virtual reality application for the test laboratory controlling was done and the requirements were met. This document provides basic guidelines with a comprehensive set of examples for developing virtual reality applications to control physical devices.
