Is the ASL technology used in ‘Echo’ real?

In “Taloa,” the fourth episode of Marvel’s grim new Disney Plus series Echo, something wild happens.

Spoilers ahead from Echo.

Well, lots of wild things happen. We get to watch Vincent D’Onofrio stomp a guy, and the first memorable case of forcible lens application in Wilson Fisk. 

The whole thing has everything that audiences love: The tech of tomorrow, the promise of being able to do something hard like learning ASL without having to try. But is it real?

Where can I get some sweet Echo ASL lenses?

Like so much of the technological goodness promised to us by the Marvel Cinematic Universe, Echo’s hand-tracking, voice-interpreting, millimeter-thin lens system is not, at present, a reality. That’s the bad news. 

The good news is, there’s so, so much good news. Tech like the stuff shown in Echo has been in the works for so long, there’s promo footage from Microsoft promising that it could be achieved using the Xbox Kinect. There are even real-time interpretation apps that’ll get the job done, albeit not through a magical AR lens, and with some issues. 

AI programs like SLAIT utilize advanced body tracking and artificial intelligence to interpret sign language as it is spoken. Critics have pointed out that it’s mostly good for direct, word-to-word translation, and that it and programs like it still struggle to pick up on the intricacies of human communication – the grace notes and subtleties that make a phrase like “eat my shorts” an insult instead of a dietary recommendation.

Additionally, fitting the tech into a monitor that you can then fit on top of your pupil will take a lot of elbow grease. Currently, a company called Mojo Vision produces a super bare-bones AR lens display, but as of 2022, CNET reported that power consumption and wireless communications interference remained an ongoing issue. It’ll be a while before the slick-as-snot animation displays seen in Echo are realistic.

Still, ask anyone born before 1970 and they’ll tell you that there was a time when the idea that a phone would fit in something smaller than a suitcase was pure science fiction. In short, keep an eye out.
