Augmented Reality (AR) is an interactive experience of a real-world environment where the objects that reside in the real world are enhanced by computer generated perceptual information, sometimes across multiple sensory modalities, including visual, auditory, haptic, somatosensory and olfactory. AR can be defined as a system that incorporates three basic features: a combination of real and virtual worlds, real-time interaction, and accurate 3D registration of virtual and real objects.

It is a growing trend among companies involved in mobile computing and business applications in particular.

Amid the rise of data collection and analysis, one of augmented reality’s primary goals is to highlight specific features of the physical world, increase understanding of those features, and derive smart and accessible insight that can be applied to real-world applications. Such big data can help inform companies' decision-making and gain insight into consumer spending habits, among others.

* Augmented reality (AR) involves overlaying visual, auditory, or other sensory information onto the world in order to enhance one's experience.

* Retailers and other companies can use augmented reality to promote products or services, launch novel marketing campaigns, and collect unique user data.

* Unlike virtual reality, which creates its own cyber environment, augmented reality adds to the existing world as it is.

What are the Augmented Reality for Public Safety?

Public Safety simply means protecting the public from calamities, crimes, and other unknown dangers which can harm the public potentially. Whether you are working for a customer service sector or engaged with some drug enforcement agency, safety is something on which you can’t compromise. The app creators of KOVA corp have understood this and, as a result, launched an AR-based application, Silent Partner, which immediately and securely captures photos or videos of unexpected events like disasters from your smartphones. Later, you (or the public safety officials or police officials) can transmit those videos or pictures which are geotagged and retrieved easily anywhere. Besides, this application has a speech analysis functionality through which the voice content can be conveyed to investigators to safeguard the public. Another AR application (iOnRoad Augmented Driving Lite App) is for drivers, which uses GPS, sensors, and native cameras on their smartphones for detecting vehicles, so that drivers can be warned before the vehicle collides. Also, if, in case, the driver misses the collision notification, then an audio-visual warning pops to guide the drivers to apply brakes or reduce the speed of the car so that they may reach the predefined spots safely and on time. Such apps act as a powerful aid to responsible citizens involved with driving companies or police departments because their minds won’t think much about those plans which aren’t appropriate from the safety perspective of the public.
