There are several questions about VR virtual reality technology for Arma 3

Various types of virtual reality technologies can be divided into four categories:

1. Desktop virtual reality

Desktop virtual reality uses personal computers and low-level workstations for simulation , using the computer screen as a window for users to observe the virtual realm. Fully interact with the virtual reality world through various input devices, including mice, tracking balls, torque balls, etc. It requires participants to use input devices to observe a 360-degree virtual realm through a computer screen and manipulate objects in it, but at this time participants lack complete immersion because it is still disturbed by the surrounding real environment. The biggest feature of desktop virtual reality is that it lacks a real reality experience, but the cost is relatively low, so it is widely used. Common desktop virtual reality technologies include: static image-based virtual reality QuickTime VR, virtual reality modeling language VRML, desktop three-dimensional virtual reality, MUD, etc.

2. Immersive virtual reality

Advanced virtual reality systems provide a fully immersive experience, giving users the feeling of being in a virtual realm. It uses a helmet-mounted display (see picture) or other equipment to seal off the participant's vision, hearing and other senses, and provides a new, virtual sensory space, and uses position trackers, data gloves (see picture), Other hand-controlled input devices, sounds, etc. make participants feel immersed, fully engaged, and immersed in the experience. Common immersive systems include: helmet-mounted display-based systems, projection virtual reality systems, and remote presence systems.

3. Augmented reality virtual reality

Augmented reality virtual reality not only uses virtual reality technology to simulate the real world, but also uses it to enhance participation The user’s feelings about the real environment, that is, the feelings that cannot be perceived or are inconvenient in augmented reality. A typical example is the head-up display for fighter pilots, which can project instrument readings and weapon aiming data onto a penetrating screen installed in front of the pilot. It can save the pilot from having to lower his head to read the data of the instruments in the cockpit, so that he can concentrate on the target. targeting enemy aircraft or navigation deviations.

4. Distributed virtual reality

If multiple users are connected together through a computer network, participate in a virtual space at the same time, and experience virtual experiences at the same time, then virtual reality will improve To a higher level, this is a distributed virtual reality system. In a distributed virtual reality system, multiple users can observe and operate the same virtual world through the network to achieve collaborative work. At present, the most typical distributed virtual reality system is SIMNET. SIMNET is composed of tank simulators connected through the network and is used for joint training of troops. Through SIMNET, simulators in Germany can run in the same virtual world and participate in the same combat exercises as simulators in the United States.
