Virtual information helps the user of the system to do real tasks
VR versus AR

In contrast to AR, VR requires more expenses on devices – a good computer with a modern graphics
card and quite expensive VR glasses. Additionally, an exposure administrators should also consider
employing is training a person to service such installation. The glasses can be damaged easily and the
users having such problems for the first time need assistance. One person can experience virtual
reality at the same time (unless two pairs of glasses are prepared).

VR and AR are different in the quality of images and the users experiences. In the case of VR, the
experience will be stronger. The user will not see the graphics put on the image from a camera and
will be free from the lightening in the room ( which can influence the quality of the image displayed
on the device). VR world has also its drawbacks, the VR glasses cover the world around us, so some
people can feel dizzy or sick, so we need to be careful while presenting them to elderly people or
children under 12.
To sum up, if a user observes using a mobile phone or a tablet and he or she can observe there a
modified version of reality, it is AR. But if special glasses are needed and a person is isolated from the
surrounding world, it is VR. Both, AR and VR influence people’s senses, especially the sense of sight.
Most users are visualizers, so perception with this sense is crucial and it has impact on the quality of
communication with the use of these technologies.

Also RR allows deep feelings, giving new stimulus. The functionality of apps using AR caters for users’
convenience. A mobile device which contains different apps is a source of knowledge, it works as an
adviser. Thanks to the apps using RR a person downloads them on his/her device, he or she uses it all
the time and it leads to a better knowledge of people, they become more connected.

AR can be widely used , in the army, motorisation, navigation, industry, medicine, visualisation of
buildings, museums, entertainment and education. The first use of AR in aviation (from 1958) as a
head-up display which helped the pilots in manoeuvring influenced the way people started
perceiving AR systems and their construction. Regardless technologies made for the purpose of
aviation, there were devices which were prototypes of modern augmented reality systems. Currently
the army is still interested in using AR systems – as the commander assistant due to their potential of
taking fast decisions by the system user.

AR used by the army it is mainly the system of head-up displays HUD- the basic equipment in planes
and helicopters. Also, HMD displays are used which are installed in helmets , they put real vector
