Chinese AR technology company Nreal and Nio have jointly developed the AR glasses for the ET5, the first time Nreal has created such a product for a car company. Li provided little information at the time, but now Nreal has given more details.

The AR glasses are based on Nreal's existing product, the Nreal Air, a giant screen theater hidden behind stylish sunglasses, the company said in a post published Monday.

"As we approach the age of the metaverse, the Nio ET5 exclusive AR glasses, developed based on Nreal Air, will help Nio make the in-car visual experience transcend the limits of space," Nreal said.

Neither Nio nor Nreal has yet released a demo video of the AR glasses, although the latter has previously released some promotional videos about the Nreal Air.

Zhu Yan, the managing partner of Nio Capital, said at the time that consumer electronics are undergoing a major generational shift as optical technology matures and arithmetic power jumps up, and augmented virtual reality terminals are expected to become the new terminals of smart life.

"We are bullish on the application of AR/VR glasses in the automotive scenario, especially the new possibilities combined with in-car entertainment ...... We are very much looking forward to Nreal as an industry innovation leader to accelerate the smart upgrade of empowered transportation and cities," Zhu said.
