How it Works

Eye movements can offer valuable insight into the complex cognitive and linguistic processes behind reading.

Using the latest in eye tracking technology to measure when, where, and how student’s eyes move in relation to the words they are reading, Lexplore can detect minor differences in the way a student’s brain processes text.

Everyone uses a combination of fixations (stopping on a piece of text) and saccades (moving across the text) when reading. A strong, efficient reader tends to have smaller fixations and longer saccades, with very few regressions (backward saccades). A weaker, less efficient reader tends to have much longer fixations and much shorter saccades, with more regressions. You can see the differences by looking at the snapshots of eye-tracking recordings above. The one on the left is a stronger reader who moves quickly and easily through the text, while the one on the right is clearly struggling.

Lexplore’s ground-breaking AI carefully analyzes each recording to provide a clear view of reading. This holistic way of understanding a student’s reading ability provides valuable insights to teachers, administrators, parents and students. Lexplore provides audio and eye-tracking recordings for each child through its web-based portal. It also includes assessment for comprehension and recommendations for instruction.
