The View-Master is the latest example of Google's virtual-reality Cardboard technology in new apps and devices. Earlier this week, LG announced a promotion to use a Cardboard-based headset for its flagship G3 smartphone.
With a working prototype of the View-Master not yet available, Mattel used a Google Cardboard headset -- which is made of cardboard -- to show off View-Master's capabilities. Here, a Nexus 5 smartphone is used as the display, offering a stereoscopic view of San Francisco's Golden Gate Bridge.
The old View-Master used circular reels of images showing landscapes or scenery. When looked at through a new View-Master, a menu of 3D images pop up out of the new reels, which then take users to 360-degree pictures.
These reels aren't actually necessary -- you could instead just download new images -- but they offer a useful nod to the View-Master's long history.
Viewing inside the Cardboard prototype, I could look all around me and click through to different views of places, like when I jumped from outside Alcatraz to inside a cell on the former island prison.
Here is CNET's Bridget Carey giving the View-Master prototype a try.
Several of the new reels for the new View-Master have pictures from decades past that were used in older versions of the toy, such as the solar-system reel that includes old pictures of astronauts on the moon.
