The Rise of AR Hardware : Journey from Computers to Smart Glasses
The journey of technology has always been about transformation. It all started with the advent of transistors and logic gates, laying the foundation for computational devices. From these roots, early controllers were born, composed of discrete components that evolved into the bulky computers of the 20th century. Then came a revolutionary shift as computers became commercialised, paving the way for handheld smartphones that soon became ubiquitous in our lives. Despite these advancements, none of these devices were wearables. But with new innovations in technology, the miniaturisation of hardware and the exponential increase in processing power, we are now entering an era where smart, wearable devices are becoming more practical and accessible.
Â
With technology advancing rapidly, people are discovering new ways to interact with digital products. These interactions come in many forms, each opening up unique possibilities. Virtual Reality (VR), for instance, immerses users entirely in a virtual world, while Augmented Reality (AR) overlays digital objects onto the physical environment. Mixed Reality (MR) offers a blend of the two, allowing for seamless transitions between virtual and augmented spaces. This spectrum of interactive technologies has created a demand for wearables that can support all three. Smart glasses are emerging as the most feasible wearable device capable of providing these interaction types.
Â
Â
The shift from smartphones to smart glasses offers several potential advantages. The immersive experience smart glasses can offer would be a considerable step up from smartphones. Blending the utility of a spectacle with advanced technology eliminates the need for a separate handheld device, making smart glasses a utility-driven device that combines functionality and cutting-edge tech. These glasses will allow users to interact with technology hands-free, bringing a level of convenience and display quality previously unattainable with handheld devices.
Â
Tech giants are racing to develop smart glasses that closely resemble ordinary spectacles but are packed with state of the art technology. Companies such as Apple, Meta, Samsung, Qualcomm, Google, Microsoft, and Magic Leap are leading this race, knowing that these glasses represent a massive shift in the tech landscape. These futuristic wearables are positioned to be the next major leap, one with the potential to create a trillion-dollar market. With their potential to replace smartphones, smart glasses may soon dominate the consumer tech market in ways we can only imagine.
Â
These smart glasses could bring about a world where people experience virtual interactions through hand and eye tracking, 6 Degrees of Freedom (6DoF) movement tracking, AI-powered processing, and multi-stream stitching using multiple cameras, providing a truly immersive experience. Surround sound, combined with an array of integrated sensors, would allow users to interact with and experience digital content in real-time. This interaction relies on hardware that can integrate data from multiple cameras and sensors and process complex algorithms that detect the environment, enabling seamless interactions with augmented virtual objects within the real world.
Â
One of the critical aspects of delivering this augmented experience is the type of display used. Holographic display technologies like birdbath optics, waveguides, and pancake lenses play a vital role in enhancing immersion. These displays enable realistic representations of digital content, providing users with the sensation of digital elements coexisting within their physical world. However, developing this technology to a level that works seamlessly within a spectacle-sized frame is a significant challenge, as these displays require tremendous processing power.
Â
Â
For now, smart glasses will likely rely on a host device to handle heavy processing tasks. This could be a smartphone or a dedicated computing module, connected to the glasses either by wire or wirelessly. Ultra-low latency and high-speed data streaming technologies make this host-device wireless connection possible, but it’s still an area where ongoing advancements are needed. The need for external processing is a temporary workaround, as developing the capacity for internal processing within the wearable itself will likely take a few more years.
Â
Despite their potential, smart glasses face several technical hurdles, especially in optics. As near-eye displays, even minor distortions or aberrations in display quality can easily be noticed by users. Addressing these optical challenges to create visually seamless and comfortable experiences is one of the main goals for hardware engineers working on these products. In addition, heat management is a concern, as these wearables can’t accommodate active cooling systems due to their compact form factor. Finding ways to dissipate or mitigate heat within the confines of a small frame is a critical design challenge.
Â
Another issue lies within the audio setup. Most smart glasses are expected to use an open-ear design, which raises privacy concerns. Open-ear designs allow users to hear ambient sound but also make it easier for sound to leak from the device, which could compromise user privacy. Although beamforming technology can direct sound toward the user’s ear canal with minimal leakage, it is not a perfect solution. Until a true privacy mode can be achieved in open-ear designs, sound management remains a concern.
Â
Finally, power management poses a significant hurdle for these glasses, as adding a battery with enough capacity to power the glasses for extended periods remains difficult. As developers work to overcome these challenges, the progress in AR hardware is undeniable. Smart glasses promise to reshape our interactions with technology, combining practicality, convenience, and an unprecedented immersive experience. From transistors to smart glasses, the journey has been extraordinary and the future of AR hardware looks incredibly promising.

They mean the same thing: the strength of your prescription. If you're nearsighted you will have a minus (-) before your values, and if you’re or farsighted you will have a plus (+).
This is for people with astigmatism. This is when one part of the eye needs more correction than the rest. The Cylinder value is written with a minus (-) sign.
This is only for people with astigmatism. The axis is a number between 0 and 180 and determines the orientation of the Cylinder (CYL).
This mainly applies if you have Progressive or Bifocal power. This mainly specifies the near spherical power or for presbyopia. Incase you want only near power, you can fill in AP value as per your prescribed details.Â
If you have only one PD value above 50, then please divide that by 2 & fill in both
eyes equally. For example for 64 PD value, Fill it with 32 and 32 for Right and Left.
In case doctor has specified these separately for each eye, you can fill them separately.
You can leave the input box empty if you don’t have them in your vision correction details.Â
