Mattel-Intellivision

Hover Force 3D (Unreleased)

In the early 1980s, researchers at the University of Georgia developed a technology for viewing three-dimensional images using glasses fitted with special prisms, and attempted to solicit interest from various video game companies.[1] Mattel Electronics began pursuing the technology, with Hover Force, then marketed as Hover Force 3-D, making its debut at the Consumer Electronics Show in Las Vegas in January 1984.[1] Mattel Electronics had developed a method for producing the glasses at low cost, and had even decided to develop two additional 3-D titles, but the company was shut down before the plans could come to fruition.[1] INTV Corporation, which acquired Intellivisions assets from Mattel, re-tooled the game and dropped any mention of 3-D for its release in 1986.[1]

The technology was later used by Crayola for their 3D Chalk toy and these glasses can be used to experience the 3D effects in this Intellivision game
