Augmented Reality (AR) and Virtual Reality (VR), do you know the difference?

The difference between augmented reality (AR) and virtual reality (VR) lies in the definition of AR and VR, their practical application in exhibitions and their future development trends.

As frequent visitors to various intelligent exhibition halls, augmented reality (AR) and virtual reality (VR) have similar names. What are the connections and differences between them?

I. Definition of AR and VR

Augmented Reality (AR) is a new technology, which can calculate the position and angle of camera images in real time and add corresponding images. It is a new technology that seamlessly integrates real world information with virtual world information. The goal of this technology is to put the virtual world in the real world and interact with it on the screen.

Virtual Reality technology (English name: virtual reality, abbreviated as VR), also known as spiritual technology, is a brand-new practical technology developed in the 20th century. Virtual reality technology includes computer, electronic information and simulation technology, and its basic realization mode is computer simulation of virtual environment, thus giving people a sense of environmental immersion.

Simply put, virtual reality is to bring the real you into the virtual world, and everything you see is an illusion, while augmented reality is to present virtual images in the real world, so that you can tell which ones are true and which ones are false.

Second, the practical application of AR and VR in the exhibition

To give a few examples, AR is widely used in the exhibition industry. It is mostly used in intelligent exhibition halls, exhibition halls, press conferences, Expo halls and other scenes, such as AR scene interaction and virtual fitting mirrors, while VR is virtual shooting, virtual skiing and virtual driving.

AR situational interaction

Put the camera above the screen or LCD screen and simulate the AR interactive logo in front of the screen. When tourists enter the camera area, real shooting scenes will appear on the video, and 3D interactive content will appear, so tourists can interact.

AR virtual fitting mirror

AR virtual fitting system captures real-time images of the scene through full HD camera, and combines with somatosensory detection equipment to superimpose 2D pictures or 3D models of clothes on customers' images, so as to realize the perfect integration of virtual clothes and real customers. When the fitting person stands in front of the virtual fitting equipment, the fitting person can see the real 3D effect of his fitting without taking off his clothes. And with the rotation of the body and the movement of the limbs, the clothes are close to the body.

VR virtual shooting simulation shooting system is to project the real environment onto a big screen or integrate it into VR equipment through a high-definition digital projector, which can display the changeable targets, swarming enemies and swooping fighters on the battlefield.

Shooter can shoot in any position and any posture by using simulated wireless light gun. The shooting process is real, the picture is realistic and dynamic. The wireless light gun adopts laser technology. After the laser is emitted, the detection system can automatically identify and convert it into a standard interface. With other large 3D shooting software, the device can be compatible with all kinds of shooting software.

VR virtual reality treadmill

When using the virtual reality treadmill, you need to wear special low-friction shoes with sensors attached to the soles. These sensors will track the speed at which you walk or run, and convert the speed into the game, so that you can travel at the same speed in the game. The sole friction of this kind of shoes is very small, but it can ensure stability and continuity in design, so that users will feel comfortable when exercising.

After putting on your shoes, you need to wear a special protective belt, which needs to be tied around your waist and thighs. This protective belt can protect you from falling down when running and leaning forward, keep your balance, release your hands, and let you run freely with M4A 1 or AK47 in the game.

Through these examples, we can compare that both VR and AR are committed to creating a realistic sensory input environment. The main difference between the two is the different requirements for immersive experience.

Virtual reality technology (VR) emphasizes the immersion of users' visual, auditory, tactile and other sensory experiences in the virtual environment, and separates users' senses from the real world. This usually requires the help of some equipment, such as a head-mounted display. After wearing it, the user's vision is blocked and he can't perceive the real environment around him. Augmented Reality (AR) is committed to integrating virtual environment with real environment, and virtual objects can be implanted into space for operation and interaction.

Third, the future development trend of AR and VR

At present, most people's cognition of VR and AR may still stay in games and entertainment. But because VR can be used to simulate some easily damaged devices, there is no risk.

AR can directly convey some basic information to users. The potential use of these technologies in health care has been gradually tapped, and VR has been used to treat patients with phobia and anxiety. It is also used to help people with autism develop social and communication skills, and to diagnose patients with visual or cognitive impairment by tracking their eye movements.

It is estimated that by 2025, the adoption of AR in the field of health care will increase at a faster rate, and the market value will increase at an annual rate of 38%. In addition, VR is also used in the field of live broadcast, mainly for sports events, entertainment ceremonies, webcasts and other activities. Short videos, social software, real estate, travel, etc. There are also footprints in VR. AR is more displayed in education, shopping experience, intelligent navigation, home decoration effect and other directions.

Whether it is augmented reality technology (AR) or virtual reality technology (VR), the ultimate goal is to make us better connected with the world. Instead of arguing about the pros and cons of the two, it is better to mix and match reality, which is the ultimate form.
