Shenzhen-based INMO is now retailing the second-generation AR glasses, called INMO Air 2, and a smart ring called INMO Ring. The INMO Air 2 is wireless, lightweight, and offers full-colour visuals and simultaneous localisation and mapping, a technology that allows robots and autonomous vehicles to build a map and locate itself within at the same time.

Compared with the first-generation AR glasses released last year, the INMO Air 2 is nearly 30% lighter and its frame thinner. The INMO Air 2 also has more functions than the previous model.

The company says combining the INMO Air 2 and the INMO Ring will allow users to play videos, browse documents and switch among different apps simply by touch, the same way they would operate a remote control.

The company explained at the October launch that the INMO Ring is Bluetooth-enabled and provides the user continuous views even if they move and look up or down.

Apart from recreation, the INMO Air 2 can also be used for work meetings, emails, document processing, and taking photographs. Outdoors, the INMO Air 2 can plot routes and can be used by walkers, runners and cyclists.

INMO is retailing the INMO Air 2 at a fixed price of 3,999 yuan (US$565) including the smart ring and started taking orders for them this month.

The Shenzhen company has raised a total of more than 100 million yuan in three funding rounds from investors including well-known Chinese firms, such as Matrix Partners China, 37 Interactive Entertainment and Unity Ventures.
