1968: The Sword of Damocles
Ivan Sutherland, a pioneer in computer graphics, developed a groundbreaking device known as "The Sword of Damocles." This head-mounted display (HMD) is considered the precursor to augmented reality (AR) technology. Although its functionality was rudimentary, consisting of simple wireframe graphics, it laid the foundation for future developments in wearable computing. However, due to its bulky size and reliance on heavy hardware, it was not feasible for everyday use.

1980: EyeTap
Steve Mann, often referred to as the "Father of Wearable Computing," invented the EyeTap, a head-mounted device designed to capture real-world images and modify them before projecting them back into the user's field of vision. This innovation marked an important milestone, as it introduced the idea of real-time visual interaction—a core aspect of modern smart glasses.

2. Advancements in Technology and Early Prototypes (1990s)

In the early 1990s, researchers at the University of Washington introduced the Virtual Retinal Display (VRD), a technology capable of projecting images directly onto the retina. This innovation was a significant step toward developing compact and lightweight wearable displays.

In 1994, the MIT Media Lab team, including Steve Mann, developed more refined wearable computing prototypes that resembled glasses. These early models allowed users to access real-time data while keeping their hands free, offering a glimpse into the potential of smart glasses as interactive digital companions.

3. Commercialization and the Rise of Augmented Reality Glasses (2000s)

How Smart Glasses Work

Smart glasses function by integrating multiple sophisticated technologies to create an interactive and immersive user experience. The core components of smart glasses include transparent displays, audio systems, control mechanisms, and cameras. Below is an explanation of how these technologies work:

1. Display Technology

The primary feature of smart glasses is their ability to present visual information in the user's field of view. Two major display technologies are used:

Curved Mirror Combiner
This method utilizes a curved mirror to reflect digital content into the user’s eyes. It allows for lightweight and compact designs, but it has limitations in resolution and field of view. Meta 2 is an example of a device that uses this technology.

Waveguide Holographic Displays
This advanced technique employs optical waveguides to project high-resolution holographic images directly into the user's vision. It offers a wider field of view and superior clarity. Devices such as Microsoft HoloLens and Magic Leap leverage this technology to create mixed reality experiences. However, waveguide holography is still costly and complex to manufacture.

2. Audio Integration

Most smart glasses come equipped with audio capabilities, allowing users to receive notifications, listen to music, or follow navigational prompts without external earphones. The preferred method for audio delivery is bone conduction technology, which transmits sound vibrations through the skull to the inner ear. This allows users to remain aware of their surroundings while receiving audio information. However, some users find bone conduction audio unnatural at first.

3. Control Mechanisms

Since smart glasses are worn on the head, conventional input methods such as keyboards or mice are impractical. Instead, alternative control mechanisms are used:
