Virtual reality (VR) and augmented reality (AR) are two technologies that are altering how we interact with displays, resulting in new and fascinating interactive experiences. In an increasingly digital environment, the phrases augmented reality and virtual reality are crucial. Despite the fact that they are two distinct technologies, both words are frequently used interchangeably. But what are the distinctions and parallels between AR and VR? Firstly, I will talk about Virtual Reality.
*What is Virtual Reality (VR)??
*
Virtual reality (VR) is a technology that creates a digital environment with computer-generated simulations that users can interact with and experience as if they were physically present within it. VR is often accompanied by the use of specialized gear, such as VR headsets, as well as various input devices, such as motion controllers or gloves. Virtual reality's primary purpose is to immerse viewers in a simulated world, which might be totally fictitious or based on real-world environments. This immersion is achieved by engaging many senses, including vision as well as aural and physical sensations on occasion.
VR headsets entirely take over your vision, creating the illusion that you are somewhere else. When worn, the PlayStation VR 2, Meta Quest 2, Valve Index, and other headsets are opaque, blotting out your surroundings. If you put them on while they are turned off, you may experience the feeling of being blindfolded. When you turn on the headsets, the LCD or OLED screens within are refracted by the lenses, filling your field of view with whatever is projected. It could be a game, a 360-degree film, or simply the virtual space between the platforms' interfaces. Visually, you are transported to wherever the headset desires—the outside world is replaced with a virtual one, hence the term. Here's how it generally works:
Headset: Users wear VR headsets, which have a pair of screens (one for each eye) that display synchronized pictures. These images are frequently somewhat varied, resulting in a stereoscopic effect that allows for depth perception.
Tracking: Tracking technology is used in VR systems to detect the user's head movements and adapt the presented graphics accordingly. Users can look around and interact with the virtual environment simply by moving their heads.
Sensory Feedback: Some complex VR installations include extra sensory feedback. Haptic feedback devices, which provide tactile sensations such as vibrations or pressure when users touch virtual things, could be included.
Input Devices: Using specialized input devices such as motion controllers, users can interact with the virtual environment. These controllers can be used to move items, navigate the virtual world, and conduct a variety of other tasks.
Audio: Spatial audio technology is used in many VR systems to mimic realistic 3D sound based on the user's head orientation and position in the virtual space.
Types of Virtual Reality (VR)
There are three primary categories of VR used today. We have:
Non-immersive VR: One of the most frequent types of VR is non-immersive VR, which uses a video game console or computer to create an experience. It involves a computer-generated virtual world in which users are aware of and control their physical environment at the same time. It is intended to allow users to influence a computer-generated environment in which they can control activities without requiring direct engagement. Video games that allow users to control a character without direct involvement are a common example of non-immersive VR. Because they are so widespread in everyday life, non-immersive virtual experiences are frequently neglected as a virtual reality category. This technique creates a computer-generated environment while still allowing the user to be aware of and manage their physical surroundings.
Semi-immersive VR: Semi-immersive VR gives an experience that is partially based on a virtual environment. It enables a virtual tour without connecting to the physical environment. Users can engage with a virtual environment using VR glasses. This means that users can exist in a virtual world without experiencing any physical sensations. To express realism, the technology relies on sophisticated, high-resolution sensors. Educational and training products that use huge projection systems and graphical computing are prominent examples of semi-immersive VR. Semi-immersive virtual experiences immerse people in a partially virtual environment. When users focus on the digital image, they will still get the impression that they are in a different reality, but they will also be connected to their physical environment. Semi-immersive technology, often known as vertical reality depth, gives realism through 3D visuals.
Fully-immersive VR: The most realistic simulation experience is fully immersive VR, which incorporates sound, sight, and sometimes smell experiences. It uses as many senses as possible to produce a realistic experience. This sort of VR is fully isolated from its surroundings. In fully immersive VR, the user physically enters the virtual world and experiences events firsthand. This is made feasible by the use of equipment such as body scanners, virtual reality headsets, gloves, smelling devices, and sense detectors. This sort of VR is commonly used in virtual game zones, where players interact with the virtual world to compete against one another. Immersive simulations provide users with the most realistic simulation experience possible, complete with sight and sound. To interact with completely realistic virtual reality, the user must wear VR glasses or a head mount display (HMD). Virtual reality headsets deliver high-resolution content with a broad field of vision. The display often divides between the user's eyes, resulting in a stereoscopic 3D effect, and works in conjunction with input tracking to create an immersive, believable experience. The applications for virtual reality are limitless.
Applications of Virtual Reality.
Gaming: VR gaming provides gamers with a far more immersive experience, allowing them to feel as if they are inside the game environment.
Training and Simulation: Industries such as aviation, military, medicine, and others use virtual reality (VR) to train employees in controlled environments, simulating events that would be too dangerous or costly in the real world.
Entertainment and Media: VR is utilized in entertainment and media for immersive storytelling, virtual concerts, and experiences such as virtual tourism.
Education: Virtual reality can provide students with hands-on experiences that are difficult to replicate in regular classrooms.
Therapy: VR is used in therapeutic applications such as phobia exposure therapy and post-traumatic stress disorder.
Architecture and Design: Architects and designers can utilize virtual reality to visualize and experience their designs before they are built.
While using VR, some individuals may feel motion sickness or discomfort. This is frequently caused by a mismatch between what the eyes see and what the body's balance system detects. Taking breaks, beginning with shorter sessions, and using VR in a well-ventilated room can all help to lessen the likelihood of motion sickness. When utilizing VR, it is critical to keep your health and safety in mind. Take regular breaks to rest your eyes, and avoid using VR for extended periods of time. Also, keep an eye on your surroundings to avoid stumbling or bumping against items while absorbed in VR. Remember that virtual reality is a dynamic and growing technology, and your experience will vary depending on the equipment you use, the content you interact with, and your own tastes. As VR evolves, now is an exciting time to investigate the possibilities and potential of this immersive technology.
What is Augmented Reality (AR)?
Augmented Reality (AR) is a technology that projects digital information onto the actual world, such as photographs, videos, 3D models, or text. Unlike Virtual Reality (VR), which totally replaces the real world with a digital one, augmented reality (AR) enhances our experience of the real world by adding virtual aspects to it. AR is frequently accessed via smartphones, tablets, AR glasses, or other wearable devices.
AR technology mixes real-time sensory information from the user's surroundings with computer-generated content to provide a combined view of both real and virtual aspects. Users can interact with both the physical and digital worlds at the same time because of this connection. Because almost everybody with a smartphone can access augmented reality, it is more effective as a branding and gaming tool than VR. By displaying virtual graphics and characters through a phone's camera or video viewer, AR transforms the dull, real world into a colorful, visual one. Augmented reality is just enhancing the user's real-world experience. The goal of augmented reality is to add to the environment by allowing virtual elements to interact with real-world things to give them their intended meanings. In augmented reality, informatively designed virtual worlds coexist with the real world by offering more facts about it. So, how exactly does augmented reality function?
How does Augmented Reality work?
Sensing: AR devices collect data about the user's environment and movements using various sensors such as cameras, gyroscopes, accelerometers, and GPS.
Processing: The collected data is transferred to a computer or device, which processes it and decides where and how virtual items should be placed in the real environment.
Overlay: Virtual content is then projected on top of the user's real-world vision. This content can be viewed on the display of the AR device, which could be a smartphone screen, AR glasses, or another type of wearable technology.
Interactions: Users can interact with virtual elements by using gestures, voice instructions, or other input techniques. The virtual content can react to the actions of the user, resulting in a dynamic and interactive experience.
Most of the time, no additional equipment is required to create an AR, which is typically generated by regular devices, mostly smartphone cameras. AR systems overlay virtual three-dimensional (3D) objects and environments on real-world items in real time based on their geometric relationships because the systems calculate the location and orientation of objects relative to others. Today, mobile phone technologies such as GPS, 3G, 4G, and remote sensing are frequently used to supplement AR technology. Typically, the integrated image is projected onto mobile phones, augmented reality glasses, and other devices.
Types of Augmented Reality
AR with Markers: Virtual content is linked to a physical marker, such as a QR code or an image. The AR content appears when the device's camera recognizes the marker.
Markerless AR, also known as location-based AR, places virtual content in particular geographic areas using GPS and other sensors.
Projection-Based AR: Virtual content is projected onto real-world surfaces to create interactive and dynamic experiences in projection-based AR.
AR based on superimposition: This includes replacing elements of the real world with virtual content. Snapchat's facial filters are an example.
SLAM (Simultaneous Localization and Mapping): Using SLAM technology, devices can recognize their surroundings and insert virtual content within them without the use of markers or GPS.
Applications of Augmented Reality
Retail and advertising use augmented reality applications extensively. AR has the ability to improve customer experiences by providing 3D models of products and assisting consumers in making better decisions. Customers can be guided to virtual stores and accommodations using AR applications.
In addition to displaying advertisements on AR products, travelers can utilize AR applications for navigation by offering information on destinations, directions, and sightseeing. They may allow users to receive recommendations for hotels to visit or to see a menu from which they may order. Furthermore, AR facilitates virtual tourism.
There are also many AR games, such as Pokémon GO, Jurassic World Alive, and others, and many of them are blockchain-based, such as Dogemon Go and Terra Virtua. The technology enables the creation of real-time 3D games for enhanced gaming experiences. AR is improving gaming in virtual worlds, allowing users to perform real-world activities.
Augmented reality enables personnel to receive training on any machine or piece of equipment "on demand," transforming their immediate surroundings into an ongoing learning platform. It can also give employees access to surroundings and scenarios that allow them to perfect their abilities while enhancing productivity and safety.
AR is useful in the training of healthcare staff, the diagnosis of patients, and the planning and monitoring of critical health situations. Fitness AR applications for ordinary users can display users' heart rates and other health statistics on-screen while they exercise. AR can help surgeons in the medical industry by overlaying medical data onto a patient's body during treatments.
