Abstract
Augmented reality offers unique opportunities for connecting the real world with the digital one through a variety of technologies. Many of these can be found in mobile phones and tablets. This chapter provides an overview of the most commonly used devices used in virtual and augmented reality (VR/AR). We will describe the history, the principle of functioning and the possibilities offered by these devices. We will also mention devices that are still under development as prototypes. The most commonly used technologies undoubtedly include LCD and OLED display devices. Nowadays, 3D displays are being developed that use many different technologies. Smart glasses will certainly be used more often in the future. Many input/output devices provide communication with VR/AR devices. These include the touchscreen, microphone, and speaker, as well as increasingly used haptic devices. This chapter will enable readers to better understand the new technologies used in VR/AR devices.
