Hello… I’ve been diving into the world of augmented reality glasses and noticed that most of the top models seem to have a field of view (FOV) ranging from 45 to 50 degrees. I’m curious about what exactly limits the FOV of these glasses.
Is it a technical limitation, or is it more of a conscious design choice by the manufacturers to keep the FOV within that range? For instance, I see that the Xreal Air 2 Pro uses a 0.55-inch micro-OLED display with a 46-degree FOV, while the Rokid Max 2 has a larger 0.68-inch display but only offers a marginally higher 50-degree FOV.
Any insights into what factors influence these FOV limits would be really helpful! Thanks in advance
The physical limits of optics constrain wearable camera FOV. While wider fields of view are achievable by sacrificing the glasses form factor (e.g., birdbath optics) or using advanced materials, these solutions often increase costs. Recent innovations combining multiple optical technologies offer promising advancements, but practical and affordable implementation remains a challenge. Ultimately, balancing desired FOV with production feasibility and consumer affordability is a critical design consideration.
The physics laws set the limit. There’s just so much that light can bend in this tiny area.
If you don’t need glasses, your field of view will be wider. Wider field of view is possible with birdbath optics. Although it obviously adds expense, using innovative materials can also assist boost FOV.
Recent research and patents have combined several optical systems to achieve complete coverage (e.g., diffraction gratings and a bird bath).
I doubt any corporation wants its goods to have a limited field of view, but it’s a design decision inasmuch as these companies need to make a product that can be made at scale at a cost that’s genuinely fair to consumers.
To be honest, it depends on the technological how of the company that made the AR Glasses. the Apple AR “Vision Pro” appears limited when compared to the “Quest 3”. It is not much difference, but it could be bigger
