Augmented reality (AR) is a live direct or indirect view of a physical, real-world environment whose elements are augmented by computer-generated sensory input such as sound, video, graphics, or GPS data. Unlike virtual reality, which creates a totally artificial environment, augmented reality uses the existing environment and overlays new information on top of it.
Augmented reality application is written in a special programming language that allows the developer to integrated animation as well as digital information in the computer program. AR applications for smartphones typically include a global positioning system (GPS) to locate and detect the exact location of the user. Some of the AR programmer used in the military for training purpose, which may include object recognition and gesture recognition
Augmented reality can reduce the risk of an operation by giving the surgeon improved sensory perception. Medical students use technology to practice surgery in a controlled environment. This technology can be combined with MRI or X-ray systems and bring everything into a single view for the surgeon.
GPS systems are using augmented reality to make it easier to get from one point to another point. Using the phone’s camera in combination with the GPS, the users see the selected route over the live view of what is in front of the car.
Augmented reality applications can complement a standard curriculum. Text, graphics, video, and audio can be superimposed into a student’s real-time environment. Textbooks, flashcards, and other educational reading material, when scanned by an AR device, produce supplementary information to the student rendered in a multimedia format. Students can participate interactively with computer-generated simulations of historical events, exploring and learning details of each significant area of the event site.
Virtual reality (VR) is an artificial environment that is created with software and presented to the user in such a way that the user belief and accepts it as a real environment. Virtual realities artificially create sensory experiences, such as sight, touch, hearing, and smell. Virtual reality is often referred to as Head Mounted Display (HMD). Holding up Google Cardboard to place your Smartphone’s display in front of your face can be enough to get you half immersed in a virtual world. The goal of the hardware is to create a virtual environment without the boundaries we usually associate with TV or computer screens. So whichever way you look, the screen mounted to your face follows you. Video is sent from the console or computer to the headset via an HDMI cable in the case of headsets such as HTS Vive and the Rift. VR headsets use either two feeds sent to one display or two LCD displays, one per eye. There are also lenses that are placed between your eyes and the pixels which is why the devices are often called goggles.
1. Education and training
The Application of VR in a training purpose is to allow professionals to conduct training in a virtual environment where they can improve upon their skills without failing the operation.
Lowe’s, IKEA, and Wayfair have developed systems that allow these company’s products to be seen in virtual reality, to give consumers a better idea of how the product will fit into their home, or allow the consumer to get a better look at the product from home.
3. Urban design
Nowadays, virtual reality can be used for urban regeneration and planning and transport projects.
