Current Trends, Challenges, and Future Prospects for Augmented Reality and Virtual Reality

2. History Of Using Ar And Vr

In the middle of the 20^th century, VR products were modelled in the form of glasses, masks (Robotics Business Review, n.d.). The reality was built using 3D imaging, widescreen vision and stereo sound. In 1970s and 1980s, the focus was on developing gloves. The first wired glove was built in 1977 and then it was improved in 1980s. The gloves used optic flex sensors for sensing and magnetic and ultrasonic waves for hand position tracking. The first functional AR system, the virtual fixtures, was built by the US Air Force in 1992 (Rosenberg, 1992)-(Rosenberg, 1993). In 1990s, the commercial AR systems were built for gaming businesses only. Later the AR/VR experience was extended to others fields: education, entertainment, communication and healthcare. In the beginning of 21^st century, advanced AR/VR systems were built utilizing computer vision techniques. In smart phones, AR/VR was used for object recognition tasks. Interactive AR systems were shown to provide realistic experience for the users through digitally manipulated information. Table 1 shows the details of AR/VR systems along with the timeline.
