Back in the early Wired magazine days, we used to joke about technology that seemed to be perpetually "just around the corner" — like storing the entire Library of Congress in a sugar cube-sized device, nanobots, and contact lens computer displays. Looks like the latter is almost ready for prime time! Just this week, startup Mojo Vision has demonstrated augmented reality in a contact lens. They've integrated a 14K pixels-per-inch display, wireless, and image and motion sensors into a wirelessly-powered device that sits in your eye. "When you close your eyes, you still see the content displayed," Mojo Vision's Steve Sinclair says. Tekla Perry wrote about the technology, called Invisible Computing, in IEEE Spectrum:
The first application, says Steve Sinclair, senior vice president of product and marketing, will likely be for people with low vision—providing real-time edge detection and dropping crisp lines around objects. In a demonstration last week at CES 2020, I used a working prototype (albeit by squinting through the lens rather than putting it into my eyes), and the device highlighted shapes in bright green as I looked around a dimly lit room….
I also saw a demonstration of text displayed using the prototype; it was easy to read. Potential future applications, beyond those intended for people with low vision, include translating languages in real time, tagging faces, and providing emotional cues….
The path ahead is not a short one; contact lenses are considered medical devices and therefore need U.S. Food and Drug Administration (FDA) approval. But the Mojo Lens has been designated as an FDA Breakthrough Device which will speed things up a little. And clinical studies have begun.
