Challenge: Existing studies on eye movement in text quality assessment are limited . eye-movement features are important predictors of human judgments of text quality, but are costly and inconsistent.
Approach: They propose to capture eye-movement features during screen reading of LLM-generated text using a dataset that includes eye-motion recordings, reading-time measurements, and post-reading evaluations.
Outcome: The proposed dataset shows that eye-movement features can significantly improve models over other probabilistic metrics, including negative log-likelihood (NLL).

Assessing Language Proficiency from Eye Movements in Reading (N18-1)

Copied to clipboard

Challenge: a novel approach to determine second language proficiency uses behavioral traces of eye movements during reading . over 1.5 billion people are learning English as a second language worldwide . traditional approaches to language proficiency testing have several drawbacks, including the fact that they are typically prepared manually and require extensive resources for test development .
Approach: They propose a method which uses behavioral traces of eye movements during reading to determine learners’ second language proficiency.
Outcome: The proposed approach correlates with standardized English proficiency tests and is validated by eyetracking with eye movements from other readers.
