Augmented Reality Eyeglasses with a Dynamic Waveguide

Smart overview of the Invention

Optical structures for augmented reality eyewear are introduced, featuring a dynamic waveguide composed of either individually-movable reflective components or adjustable-reflectivity components. These innovations allow users to view a bright, opaque virtual object in one part of their field of view while maintaining a clear view of their surroundings in the remaining area. This dual capability enhances the augmented reality experience by integrating virtual elements seamlessly with the real world.

Applications

Augmented reality (AR) eyeglasses have a wide range of potential applications spanning various fields such as commerce, defense, education, entertainment, and medicine. By enabling the simultaneous visualization of real-world environments and virtual objects, these glasses can facilitate activities like interactive learning, virtual shopping, enhanced navigation, and immersive gaming experiences. This technology also holds promise for improving public safety, social interactions, and sports by overlaying useful information directly onto the user's field of view.

Technological Context

The development of these optical structures builds on existing technologies in electronic devices with adjustable optical components. Prior art includes devices with adjustable reflectance and transmittance layers, electrically adjustable shutters, and systems with holographic gratings. The current invention distinguishes itself by focusing on dynamic waveguides that enhance the user's ability to interact with virtual objects while maintaining awareness of their physical environment.

Illustrations

Several figures illustrate different configurations of the augmented reality eyeglasses. These include vertically-pivoting waveguides, waveguides on transparent rotatable components, and laterally-pivoting and sliding waveguides. Additionally, designs with vertically and radially converging waveguides, as well as overlapping waveguides for both sides, are presented. An innovative design features a dynamic waveguide with adjustable thickness, showcasing the versatility of these optical structures.

Conclusion

The dynamic waveguide technology in augmented reality eyeglasses represents a significant advancement in integrating virtual and real-world environments. By enabling clear visualization of both virtual objects and the surrounding environment, these optical structures enhance the practical applications of AR technology across numerous domains. The development of this technology paves the way for more immersive and interactive experiences in both professional and recreational settings.
