How CastAR’s Jeri Ellsworth will use augmented reality for fun tabletop gaming

Jeri Ellsworth and Rick Johnson have been toiling away at augmented reality for years at their startup, CastAR. Their ambition to make a fun AR product has been cooking for a while, and they’re taking a very different approach to the next-generation gaming platform.

And given Ellsworth’s background as an underdog, it’s no surprise she’s trying to think different. Ellsworth taught herself how to design chips and became known in 2004 for creating a Commodore 64 system on a chip with a joystick. She went on to become a hardware hacker and was part of a team of researchers at Valve, the maker of the Half-Life games and the new SteamVR virtual reality technology.
