Everything You Need To Know About Smart Glasses

What Are Smart Glasses?

As you can glean from the name, smart glasses combine the use of technology with regular eyeglasses to deliver interactive and immersive visual experiences. They can be used for a wide range of purposes across diverse industries.

They usually leverage wireless connectivity, such as Bluetooth and Wi-Fi, to connect with apps on other devices such as smartphones, tablets, smart watches, and more.

Smart glasses form one aspect of wearable technology that offer visual stimulation. Depending upon the level of immersivity they offer, smart glasses are broken down into three primary types—augmented reality (AR), virtual reality (VR), or hybrid (mixed reality).

Typically, smart glasses refer to the devices that look and feel like traditional glasses but add intelligent, digital displays that deliver enhanced visual experiences. However, true AR/VR experiences are delivered by bigger, heavier and more complex devices known as headsets.

Today, we’re going to explore about smart glasses rather than AR/VR headsets, but it’s important to know their differences. Read on!
 

What’s The Difference Between Smart Glasses And AR/VR Headsets?

The primary difference between these two depends upon the experiences they deliver.
 
Smart glasses are designed to leverage AR technology to overlay digital content on top what a user sees in the real world, allowing them to see part of the real world and part of the display. On the flipside, VR headsets immerse users into virtual worlds by completely cutting out what a user sees in the real world.

When it comes to physical attributes, smart glasses are lighter and easy to where anywhere. They look like traditional eyewear. They can use transparent lenses, tinted lenses, or monochromatic lenses that allow users to adjust the tint levels. This makes them efficient to use on the go.

VR headsets are larger, heavier, and are often wired. They fit over a user's whole head and thus are better suited for stationary use. Additionally, the pricing for majority of smart glasses is lower than AR/VR headsets.

Despite these differences, these two types share a common foundation!
 

What Is The History Of Smart Glasses?

Whether you believe it or not, the history of smart glasses and VR headsets stretches all the way back to the 1960s when American computer scientist Ivan Sutherland introduced the concept, calling it “The Ultimate Display.”

He described what he thought the finished product would be like, saying “The ultimate display would, of course, be a room within which the computer can control the existence of matter. A chair displayed in such a room would be good enough to sit in.”

Sutherland went on to create a head-mounted, three-dimensional display capable of visually overlaying a user’s physical environment. The display even had a suspending counterbalance mechanical arm, while it used ultrasonic transducers to track the head movement.
 
Since then, progress remained relatively slow in comparison to the last ten to fifteen years, and of course, we’re a bit away from smart glasses or VR headsets capable of manifesting changes in the real, physical world.

However, the base principles set by Sutherland remain true even in the designing of modern smart glasses, including a display, processors, sensors, image rendering, and more.

So, how do modern smart glasses work?
 

How Do Smart Glasses Work?

Smart glasses host a miniature computer on board (known as a microcontroller), which allows it to run applications locally or connect to the internet or cloud-based applications. This allows users to complete various daily personal and professional tasks.

On the other end of the circuit is an advanced, complex, and powerful display system that projects images in a user’s line of vision. This could be by superimposing imagery on the glasses overlaying the real world or projecting it into their eyes directly. Did you know they can even come with prescriptive lenses? #NowYouSeeClearly

To deliver such experiences, smart glasses make use of cameras, sensors, buttons, and Bluetooth, Wi-Fi, and other wireless technology. For audio capabilities, they leverage microphones and built-in speakers or bone conduction technology.

Smart glasses offer a variety of functions, features, and capabilities, including calling, emailing, capturing photos, recording videos, browsing the web, voice control, surfing social media platforms, watching movies, navigation, receiving notifications, tracking physical activity, getting live translations, controlling smart home devices, monitoring health, using AI assistants, and more. Naturally, Artificial intelligence (AI) technology has become a big hit with modern smart glasses!

With such diverse use cases—and more being added every day—it’s no surprise that the market is flooding with smart glasses. In fact, reports indicate that the global smart glasses market is expected to grow from $878.8 million in 2024 to $4,129.3 million by 2030 with a CAGR of 29.4%.
