Augmented reality courses in chennai

I wish I could see how this hair color suits me before coloring my hair, I wish I could try that outfit before ordering it online. How many of us have had these thoughts before buying something or availing a service? What if you were told that all your fantasies could come true without having to spend any money? That is what augmented reality is all about. Augmented reality is a seamless transition between reality and perceived reality. Unlike virtual reality that creates an artificially simulated environment, augmented reality adds on to the existing physical environment.

Augmented reality plays with all the senses such as haptic, olfactory, somatosensory, visual and auditory in a human body. Augmented reality is of four types. They are:

  • Markerless AR: This is where, the device automatically recognizes the surroundings and objects and comes up with corresponding augmented reality. This is a little tedious since, the AR application has to recognize new images and patterns and keep developing algorithms accordingly.
  • Marker based AR: This is image or symbol based augmented reality where, the image or symbol or some kind of visual data has to be pre loaded into the camera or whatever scanning device is being used and this gets converted into 3D models.
  • Projection based AR: Projection based augmented reality creates holograms and gives audio visual cues for various operations. It operates a digital working space, avoiding the need for any hard copy or other kinds of manual instructions.
  • Superimposition based AR: Super imposition technique creates an augmented view of the object either entirely or partially helping in seeing replacement of certain parts in complex machines. It works on the concept of object recognition.

How does augmented reality work?

  • Cameras and sensors: Both the camera and sensor are located on the outside of the device. It captures the images and patterns from the outside world and transfers it into digital content in order to process the information for bringing out an appropriate output.
  • Projection: This is the system that creates a projection onto any surface without the requirement for any external device to do so. This is done by the projector attached to the device that projects the processed digital data in a format understandable to the human mind.
  • Processing: AR devices use almost all the components used by a computer but, it is more compact. The AR devices have elements such as:
  • Accelerometer- to measure the speed in which the wearer’s head is movie
  • Gyroscope- to measure the tilt and orientation of the wearer’s head
  • Magnetometer- like a compass to find the direction in which the head is turned.
  • These are the things that give the realistic experience in augmented reality.
  • Reflection: Mirrors are used in augmented reality devices to assist with the way your eye views the virtual image. Some augmented reality devices may have “an array of many small curved mirrors” and others may have a simple double-sided mirror with one surface reflecting incoming light to a side-mounted camera and the other surface reflecting light from a side-mounted display to the user’s eye. In the Microsoft Hololens, the use of “mirrors” involves see-through holographic lenses (Microsoft refers to them as waveguides) that use an optical projection system to beam holograms into your eyes. A so-called light engine, emits the light towards two separate lenses (one for each eye), which consists of three layers of glass of three different primary colors (blue, green, red). The light hits those layers and then enters the eye at specific angles, intensities and colors, producing a final holistic image on the eye’s retina. Regardless of method, all of these reflection paths have the same objective, which is to assist with image alignment to the user’s eye.
