How does Augmented Reality work?
In most applications user can see both synthetic and natural light. This is done by overlaying projected images on top of a pair of see-through goggles or glasses, which allow the images and interactive virtual objects to layer on top of the user’s view of the real world. They do not need any cable to function. Types of augmented reality –
- Marker Based – These uses a camera and a simple 2D/QR code to produce the result. Simple distinct patterns are used to produce marker. Markers can be easily recognized. They do not need much of processing power to read.
- Markerless – It is one of the most widely used type. uses a GPS, digital compass, velocity meter, or accelerometer which is embedded in the device to provide data based on your location. It is most commonly used for mapping directions, finding nearby businesses, and other location-centric mobile applications.
- Projection Based – It works by projecting artificial light in the real-world objects and sensing human interaction with the light. This can be used for projecting 3-D hologram in the mid-air.
- Superimposition based – This type either partially or fully replaces the original view of an object with the augmented view.
Let’s look on the various applications of augmented reality
- Medical Uses – Medical students uses this technology to practice surgery in controlled environment. Visualizations aid in explaining complex medical conditions to patients. Augmented reality can reduce the risk of an operation by giving the surgeon improved sensory perception.
- Military Uses – The Heads-Up Display is the typical example of an application of this technology in the military. Data displayed includes altitude, airspeed and the horizon line in addition to other critical data.
- Apps for Navigation – It is the most common application of this technology which is used by most of us in our everyday lives.
Its other application includes gaming, advertising and promotion, sightseeing etc. Augmented Reality is a very helpful tool in our everyday life as it brings elements of the virtual world, into the real world, enhancing the things we see, hear and feel.
