Quick Start
Overview
The CloverAir series is a glassed-style electronic video
magnifier focused on improving vision perception for visually
impaired person. It provides clear image quality while offering
unrestricted portability, supporting mobile use in all indoor
and outdoor scenarios.
The CloverAir low-vision AR glasses use a modular design
that separates the computing unit, battery, and display optical
module into two independent parts, greatly reducing the
weight of the glasses (around 80g) and heat generation
(around 30°C), improving comfort for long-term wear. The
glasses are creatively equipped with dual cameras. The front
main camera captures visual information such as text and
objects and processes it through algorithms to achieve image
magnification, contrast enhancement, and color optimization.
The processed image is then projected onto the glasses'
binocular HD OLED display module. When switched to the
close-up camera, users don’t need to lower their heads
excessively to capture content on a desk, greatly improving
the experience of reading and writing on paper at a desk.
In addition, CloverAir is equipped with OCR, mobile screen
mirroring, external HDMI input, and a variety of other features
3
and interfaces to seamlessly meet the daily needs of visually
impaired person.
