Title:
EYE MOVEMENT ANALYSIS WITH CO-CLUSTERING OF HIDDEN MARKOV MODELS (EMHMM WITH CO-CLUSTERING) AND WITH SWITCHING HIDDEN MARKOV MODELS (EMSHMM)
Document Type and Number:
WIPO Patent Application WO/2021/087651
Kind Code:
A1
Abstract:
Provided are an Eye Movement analysis with Hidden Markov Model (EMHMM) with co-clustering, an Eye Movement analysis with Switching Hidden Markov Models (EMSHMM) to analyze eye movement data in cognitive tasks involving stimuli with different feature layouts and cognitive state changes, a switching hidden Markov model (SHMM) to capture a participant's cognitive state transitions during the task and an EMSHMM to assess preference decision-making tasks with two or more cognitive states. The EMSHMM provides quantitative measures of individual differences in cognitive behavior/style, making a significant impact on the use of eye tracking to study cognitive behavior across disciplines.
