Augmented reality devices are often controlled by either touching a pad or voice control that’s kept somewhere reachable to the owner or the person using it. The touch pads work when the pads sense the pressure when a particular user taps on a particular area or swipes a particular spot and acts accordingly. Voice commands are simple as they pick up your voice and interpret the commands that we give using the tiny microphone on device a microprocessor for interpreting. For example, voice commands on Google Class Augmented Reality Device having a pee-programmed list of commands that we can use where each of them starts with a command “OK, Glass" alerts the glass for the commands that’s to be followed after that.
There are a few technologies that make up augmented reality:
Marker Based Augmented Reality
Marker Based Augmented Reality use cameras and some visual aid such as QR/2D code to produce a result when the visual aid is being sensed. Scanning a QR code and producing its types of results is an example of this.
Markerless Augmented Reality
Markerless Augmented Reality use a GPS, digital compass, velocity meter and accelerometer embedded into a particular device. This is used in locating a place, mapping directions, finding a nearby business and other GPS based services.
Projection based Augmented Reality
This is basically projecting light onto a real-world space and then sensing the human interaction. One example is projecting 3D interactive hologram into mid-air.
Superimposition Based Augmented Reality
Superimposition based augmented reality either partially or fully replaces the original view of an object with a newly augmented view of that same object. This is done by downloading an app and scanning selected pages in their printed or digital catalogue, users can place virtual ikea furniture in their own home with the help of augmented reality.
The components in an augmented reality device include sensors and cameras, projection, processing and reflection. All devices usually put augmented reality directly onto your face, usually in the form of a glass. Sensors usually on the outside of a device, gather all the interactions and communications and cameras on outside of the device used for scanning the surrounding area. “Projection based augmented reality” is a category in-itself, is usually referred to miniature projection that appears outwardly when a wearable augmented reality headsets is worn. In the future, you may not need an iPad to play an online game because you will be able to play it on the tabletop in front of you.
Augmented reality devices are basically mini-supercomputers packed into tiny wearable devices having high processing power and utilize the same components as the smartphones. Mirrors are used in AR devices to assist with the way the virtual image is viewed.
Many companies starting from Facebook to Amazon want a part of the nascent market for virtual and augmented reality. With equipments like Facebook’s Oculus Rift, people go deep and immerse themselves into the digital and virtual world and is also becoming Apple and Google’s next battleground. Source tells us that,”It could become a converged solution that complements and potentially even replaces the smartphone, depending on the context.”
