AI May Help Screen for Dyslexia

Despite all of technology’s advances and the many data dashboards available to track classroom performance, screening children for dyslexia is still typically conducted using paper tests, whose evaluation can fall prey to subjectivity on the part of teachers.

Lexplore, a Swedish company operating in the U.S. out of Naperville, IL, hopes to employ eye-tracking cameras on computers with artificial intelligence and special algorithms to identify more students with dyslexia who might be missed by the current outmoded, time-consuming method.

The company’s tools analyze patterns in how a subject’s eyes follow words in sequential or nonsequential order as they read. Those at high risk for dyslexia make more right-to-left movements—vs. the more normal left-to-right—and take fewer or no regular pauses during reading.

Although its tech and algorithms are new, Lexplore’s underlying ideas draw on research dating back for decades that indicates tracking eye movements is one of the best ways to gauge reading ability. A 2015 study built a statistical model using eye-tracking that could identify dyslexia with more than 80% accuracy.

Two of Lexplore’s co-founders published their own study in 2016 that claimed an even higher success rate of 95.3% using their own technology, which is now in use across the city of Stockholm’s municipal education board.

In the U.S., Lexplore is still fine-tuning its business model and has so far only been tested in a handful of private schools in the Atlanta area.
