Apple Granted Two AR Glasses Patents: Passive Cooling Design and Digital Crown Interaction


In a recent development, Apple Inc. has been granted two patents related to augmented reality (AR) glasses, demonstrating the company's continued innovation in the AR space. These patents focus on a passive cooling design and a digital crown interaction feature.

Passive Cooling Design:

The first patent revolves around a passive cooling design for AR glasses. These glasses feature a surface coated with transparent and thermally conductive materials, such as silver nanowires. This coating provides stability in coloration, maintains a relatively low production cost, and offers excellent thermal conductivity and light transmittance. Importantly, it achieves efficient passive cooling by enlarging the effective cooling surface area.

Passive cooling is essential for AR glasses, as they often generate heat during extended use. Efficient heat dissipation ensures user comfort and device performance, making it a crucial aspect of AR glasses' design and usability.

Digital Crown Interaction:

The second patent introduces a digital crown interface integrated into the frame of AR glasses. This digital crown is strategically positioned at the temple of the glasses, providing an intuitive interaction method for users. While eye-tracking technology has its role in AR interactions, the digital crown offers an alternative means of control.

The patent elaborates that users can manipulate applications using their fingers, interacting with the digital crown. This interaction allows for various actions, such as moving or altering applications. It enhances the overall user experience by providing a tactile and precise method of control.


Apple's investment in AR technology continues to evolve, as evidenced by these newly granted patents. The passive cooling design addresses a crucial issue of heat management in AR glasses, ensuring prolonged comfort and device reliability. The incorporation of a digital crown offers an additional layer of interaction, giving users more control over their AR experience.

While these patents showcase Apple's commitment to AR innovation, it's important to note that patents don't always directly translate into finalized products. However, they do provide insights into the company's research and development efforts, hinting at exciting possibilities for the future of AR glasses.
