Smart Glasses Without Cameras: The Future?
22 Aug
Summary
- Smart glasses cameras offer redundant photo/video capabilities compared to phones.
- AI machine vision on smart glasses is better on phones with larger screens.
- Camera-free smart glasses represent a growing and optimistic trend in wearable tech.
Camera-equipped AI smart glasses are attracting negative attention due to their potential for misuse by individuals for spying and privacy invasion. This has led to a growing movement towards camera-free smart glasses, which offer a more positive outlook for wearable technology.
The primary functions of cameras in smart glasses, such as capturing photos and videos or enabling machine vision, are often surpassed by smartphones. Smartphone cameras generally offer superior image quality due to larger sensors and lenses, while machine vision is more effectively utilized on a phone's screen.
While cameras can enable head tracking, this feature is either limited or unnecessary for many current smart glasses. Upcoming models with advanced displays, like waveguide technology, are increasingly omitting cameras, with several manufacturers prioritizing this feature.
Waveguide displays project information directly into the user's line of sight, offering potential for notifications, captions, and directions without cameras. Although still developing, this technology, as seen in models from companies like Captify and RayNeo, promises utility without compromising privacy.
