Chan et al, 2022), sustained attention to response (Lee et al, 2021), website viewing (Eckhardt et al, 2013), video viewing (Zheng, Ye, & Hsiao, 2022), scene perception (Hsiao, Lan, et al, 2021), reading (Liao et al, 2022), and visual search (Hsiao, Chan, et al, 2021). EMHMM is based on the assumption that the current fixation in a visual task is conditioned on the previous fixation, and thus eye movements in the task may be considered a Markovian stochastic process, which can be better understood using hidden Markov models (HMMs).…”
