Precise measurement of the position of the eye as it follows a moving target makes possible the exact computation of retinal information about the path of movement of that target. Comparing this retinal information with the reported visual perception of the path of movement enables inferences to be made concerning what information about eye position was used by the perceptual system. On the ass...

Conventional analyses on eye movement data only take into account eye movement metrics, such as the number or the duration of fixations and length of the scanpaths, on which statistical analysis is performed for detecting significant differences. However, the spatial dimension in the eye movements is neglected, which is an essential element when investigating the design of maps. The study descr...

Most of sleep disorders are diagnosed based on the sleep scoring and assessments. The purpose of this study is to combine detrended fluctuation analysis features and spectral features of single electroencephalograph (EEG) channel for the purpose of building an automated sleep staging system based on the hybrid prediction engine model. The testing results of the model were promising as the class...

The present study investigated the relationship between eye movement pattern in face recognition and cognitive performance during natural aging through modeling and comparing eye movement of young (18-24 years) and older (65-81 years) adults using Hidden Markov Model (HMM) based approach. Young adults recognized faces better than older adults, particularly when measured by the false alarm rate....

Cognitive effort measures inferred from eye movement patterns during textural information search have been correlated with subjective task difficulty and objective measures of task effort. Analysis of the same cognitive effort measurements in an independent user study (n=40) of recall-oriented search in the genomics domain reveals strong correlations with self-assessed domain knowledge. A simpl...

Rapid eye movements and complex visual dreams are salient features of human rapid eye movement sleep. However, it remains to be elucidated whether the eyes scan dream images, despite studies that have retrospectively compared the direction of rapid eye movements to the dream recall recorded after having awakened the sleeper. We used the model of rapid eye movement sleep behaviour disorder (when...

objective: early recognition of negative emotions is considered to be of vital importance. it seems that children with attention deficit hyperactivity disorder have some difficulties recognizing facial emotional expressions, especially negative ones. this study investigated the preference of children with attention deficit hyperactivity disorder for negative (angry, sad) facial expressions comp...

Analysis of eye movement data provides a valuable methodology to evaluate and inform user interface design. However, there are a number hurdles that must be overcome on the path to successfully gaining meaningful eye movement data. We describe how we used a commercially available eye tracking system to evaluate a new interface for personal desktop search called Phlat. A small eye-tracking user ...

Evaluating the effectiveness of the visual design of an interface is an important yet challenging problem. In this paper, we introduce the VERP (Visualization of Eye movements with Recurrence Plots) Explorer, a visual analysis tool for exploring eye movements during visual-cognitive tasks. The VERP Explorer couples conventional visualizations of eye movements with recurrence plots that reveal p...
