When Were Smart Glasses Invented


The First Underpinnings of Smart Glasses

The concept of smart glasses may seem like a relatively recent technological advancement, but the roots of this innovative device can be traced back several decades. The early development of smart glasses laid the foundation for the sophisticated wearable technology we have today.

In the late 1960s, a concept called “augmented reality” emerged, paving the way for the creation of smart glasses. Ivan Sutherland, a computer scientist, introduced the concept of a “head-mounted display” or HMD, which involved wearing a device that projected computer-generated graphics onto the wearer’s field of view.

However, it wasn’t until the early 1980s that the first true smart glasses prototype was developed. Stephen Mann, a professor at the University of Toronto, coined the term “wearable computer” and designed a device called the “Remote Associate Memory” or RAM, which featured a head-mounted display with a small camera and display to provide augmented reality experiences.

These early iterations of smart glasses were rudimentary compared to the advanced technology we have today, but they were groundbreaking at the time. They laid the groundwork for further research and development in the field.

The concept of augmented reality continued to gain traction throughout the 1990s, with researchers and technology companies exploring different applications and capabilities. Though progress was slow, the potential of smart glasses and their ability to overlay digital information onto the wearer’s real-world view captured the imagination of many.

During this period, companies like Reflection Technology and MicroOptical Corporation made significant strides in developing head-worn displays and wearable computing devices. These early attempts paved the way for the future of smart glasses, setting the stage for the breakthrough that was yet to come.

The first major turning point for smart glasses came in 2013 when Google introduced Google Glass. This wearable device revolutionized the market, bringing smart glasses into the mainstream. Google Glass featured a head-mounted display with a built-in camera, microphone, and wireless connectivity, allowing users to access information, take photos and videos, and interact with various apps.

Despite the initial hype and excitement surrounding Google Glass, the device faced challenges and was eventually discontinued in 2015. However, its impact cannot be underestimated. Google Glass brought the concept of smart glasses to the forefront of public attention and inspired other companies to invest in developing their own versions.

Since then, the evolution of smart glasses has continued, with companies like Microsoft, Apple, and Facebook entering the market. These modern smart glasses offer enhanced functionalities, such as improved augmented reality capabilities, voice assistants, and integration with smartphones and other devices.

Today, smart glasses are increasingly being adopted in various industries, including healthcare, manufacturing, and logistics. They have the potential to enhance productivity, improve efficiency, and provide personalized experiences.

The journey of smart glasses, from their conceptualization in the 1960s to the sophisticated devices we have today, is a testament to the relentless pursuit of innovation and the desire to blend the digital and physical worlds seamlessly.


The Early 1980s: A Pioneering Era

The early 1980s marked a significant era in the development of smart glasses. It was during this time that pioneering researchers and innovators began to explore the possibilities of wearable computing devices, laying the groundwork for the future of this revolutionary technology.

One of the notable figures of this era was Steve Mann, a professor at the University of Toronto. Mann is often referred to as the “father of wearable computing” for his groundbreaking work in the field. In 1980, he created the first known wearable computer prototype, named “WearComp 1.” This early device consisted of a backpack-sized computer along with a head-mounted display, allowing the wearer to interact with computer-generated graphics and information in real-time.

Mann continued to refine his invention throughout the early 1980s, experimenting with various iterations of wearable computing. His work laid the foundation for the concept of smart glasses, as he pioneered the integration of augmented reality into wearable technology. Mann’s devices were early precursors to the modern smart glasses we know today.

During the same era, Thad Starner, another influential figure in the world of wearable computing, made significant contributions. Starner developed the “Twiddler,” a one-handed chorded keyboard that allowed users to input data while wearing a head-mounted display. His work focused on creating wearable systems that could seamlessly integrate into everyday life, emphasizing the importance of usability and human-computer interaction.

These pioneers faced numerous technical challenges in developing smart glasses during the early 1980s. Limited processing power, cumbersome hardware, and the lack of advanced display technologies posed significant obstacles. However, their perseverance and vision propelled the evolution of wearable computing forward.

The early 1980s also saw the establishment of the International Symposium on Wearable Computers (ISWC) in 1997. This conference provided a platform for researchers, engineers, and industry professionals to share their work, collaborate, and further push the boundaries of wearable computing technology.

As the decade progressed, interest in wearable computing and smart glasses began to grow. Research institutions and companies started to explore the potential applications of wearable technology in various fields, from healthcare to military operations.

The early 1980s set the stage for further advancements, fueling the imagination of researchers and serving as a springboard for the future development of smart glasses.


The Concept of Augmented Reality

Central to the development of smart glasses is the concept of augmented reality (AR). Augmented reality refers to the integration of computer-generated content with the user’s real-world environment, enhancing their perception and interaction with the surrounding world.

The idea of augmented reality can be traced back to the late 1960s when Ivan Sutherland, a computer scientist, introduced the concept of a “head-mounted display” (HMD). Sutherland envisioned a device that would overlay computer-generated graphics onto the user’s field of view, blending the virtual and physical world together.

The term “augmented reality” was coined in the early 1990s by Tom Caudell, a researcher at Boeing, who used it to describe a digital display system he was developing to assist aircraft assembly workers. This marked a significant milestone in the evolution of augmented reality as a distinct field of study and development.

The underlying technology behind augmented reality revolves around computer vision, tracking, and image recognition. By using cameras, sensors, and sophisticated algorithms, smart glasses can detect and analyze the user’s surroundings, pinpointing objects and landmarks to provide real-time information and interactive experiences.

Augmented reality offers a wide range of applications, spanning from gaming and entertainment to healthcare, education, and industrial use cases. For example, in the healthcare industry, smart glasses equipped with AR capabilities can assist surgeons during complex procedures by providing real-time guidance and visual overlays.

Another area where augmented reality shows immense promise is in training and education. Smart glasses can create immersive learning experiences where students can interact with 3D models and virtual simulations, enhancing their understanding and retention of complex concepts.

One of the key benefits of augmented reality is its ability to bridge the gap between the digital and physical worlds seamlessly. By overlaying virtual information onto the real environment, smart glasses empower users with enhanced context and situational awareness, leading to improved decision-making and productivity.

As the technology and capabilities of AR continue to advance, the potential for smart glasses to transform various industries becomes more apparent. The ability to access information, communicate, and interact with digital content hands-free and on the go opens up a new realm of possibilities.

Augmented reality has come a long way since its early conceptualization, and it continues to push the boundaries of what is possible. As smart glasses evolve, so too will the opportunities for integrating augmented reality into our daily lives, making the digital world an integral part of our physical reality.
