TechInsights Teardown: Dream World Dream Glass AR headset

The metaverse was one of the major buzzwords in 2022, but it looks like this year will continue to follow the market path toward commercialization both for consumers and businesses.

Augmented reality (AR), virtual reality (VR) and extended reality (XR) were all a thing prior to the birth of the metaverse, used mostly for gaming or industrial applications. But now developments are accelerating in anticipation that the market will likely grow tremendously in the coming years. Or it could continue to trudge along with mostly early adopters being the main users.

Enter Dream World’s Dream Glass Lead Pro AR goggles. The AR headset features a Snapdragon processor and 3 GB of mobile synchronous dynamic random access memory (SDRAM) as well as a host of microelectromechanical systems (MEMS).
