Reality is very personalized, it is how we perceive the world around us, and it shapes our existence. And while individual experiences vary widely, for as long as humans have existed, the nature of our realities have been broadly relatable from person to person. My reality is, for the most part, at least explainable in terms of your reality. Yet as technology grows better and more widespread, we are coming closer to an era where my reality, at least for a period of time, may be completely inexplicable in the terms of your reality. There are two main ways to do this: virtual reality and augmented reality. In virtual reality, technology immerses you in a different, separate world. My earlier article on VR was the first of this two-part series, and can be found HERE.

Whereas virtual reality aims to totally replace our reality in a new vision, augmented reality does what the name suggests: it augments, changes, or adds on to our current, natural reality. This can be done in a wide variety of ways, the most popular currently being a close-to-eye translucent screen with projected graphics on top of what you are seeing. This screen can take up your whole field of view, or just in the corner of your vision. Usually, the graphics or words displayed on the screen is not completely opaque, since it would then be blocking your view of your real reality. Augmented reality is intrinsically designed to work in tandem with your current reality, while VR dispenses it in favor of a new one.

With this more conservative approach, augmented reality (AR) likely has greater near-term potential. For VR, creating a new world to inhabit limits many of your possibilities to the realm of entertainment and education. AR, however, has a practically unlimited range of use cases, from gaming to IT to cooking to, well, pretty much any activity. Augmented reality is not limited to, but for now works best as a portable heads-up display, a display that shows helpful situational information. For instance, there was a demo at Epson’s booth at Augmented World Expo 2015 where you got to experience a driving assistance app for AR. In my opinion, the hardware held back the software in that case, as the small field of view was distracting and the glasses were bulky, but you could tell the idea has some potential. At AWE, industrial use cases as well as consumer use cases were also prominently displayed, which included instructional IT assistance, such as remotely assisted repair (e.g., in a power plant, using remote visuals and audio to help fix a broken part). 

Before I go on, I have to mention one product: Google Glass. No AR article is complete without mentioning the Google product, the first AR product to make a splash in the popular media. Yet not long after Google Glass was released, it started faded out of the public’s eye. Obvious reasons included the high price, the very odd look, and the social novelty: people couldn’t think of ways they would use it. Plus, with the many legal and trust issues that went along with using the device, it often just didn’t seem worth the trouble. Yet rumor has it that Google is working on a new, upgraded version of the device, and it may make a comeback, but in my opinion it’s too socially intrusive and new to gain significant near-term social traction.

Although many new AR headsets are in the works (most importantly Microsoft’s HoloLens), the development pace is lagging VR, which is already to the stage where developers are focused on enhancing current design models, as I discussed in the previous VR article. For AR, the situation is slightly different. Hardware developers still have to figure out how to create a cheap AR headset, but a headset that also has a full field of view, is relatively small, doesn’t obstruct your view when not in use, and other complications like that. In other words, the hardware of AR occasionally interrupts the consumption of AR content, while for VR hardware, the technology is well on its way to overcoming that particular obstacle.

Beyond these near-term obstacles, if we want to get really speculative, there could be a time when VR will surpass AR even in pure utility. This could occur when we are able to create a whole world, or many worlds, to be experienced in VR, and we decide that we like these worlds better. When the immersion becomes advanced enough to pass for reality, that’s when we will abandon AR, or at least over time use it less and less. Science fiction has pondered this idea, and from what I’ve read, most stories go along the lines of people just spending most of their time in the virtual world and sidelining reality. The possibilities are endless in a world made completely from the fabric of our imagination, whereas in our current reality we have a lot of restrictions to what we can do and achieve. Most likely, this will be in a long, long time, so we have nothing to worry about for now.

Altogether, augmented reality and virtual reality both are innovative and exciting technologies and that have tremendous potential to be useful. On one side, AR will be most likely used more than VR in the coming years for practical purposes, since it’s grounded in reality. On the other hand, VR will be mostly used for entertainment, until we hit a situation like what I mentioned above. It’s hard to pit these two technologies against each other, since they both have their pros and cons, and it really just depends on which tech sounds most exciting to you. Nonetheless, both AR and VR are worth lots of attention and hype, as they will both surely change our world forever, for better or worse.
