The effects of stressful arousal on conjugate lateral eye movement. Seo H. Sihite D. N. Abstract In a very influential yet anecdotal illustration, Yarbus suggested that human eye-movement patterns are modulated top down by different task demands.While the hypothesis that it is possible to decode the observer's task from eye movements has received some support (e.g., Henderson, Shinkareva, Wang, Luke, & Olejarczyk, 2013; Iqbal & Bailey, 2004), Greene, Liu, and Wolfe .

A computational model for task inference in visual search. Students' majors were computer sciences, neuroscience, psychology, mathematics, cognitive sciences, communication, health, biology, sociology, business, and public relations. Mack M. Napoletano P. Tatler B. W. We investigate the predictive value of task and eye movement properties by creating a computational cognitive model of saccade selection based on . Yarbus concluded that the eyes fixate on those scene elements that carry useful information, thus showing where we look depends critically on our cognitive task. In our view an important limitation of Greene et al. Castelhano M. (2012). Spontaneous eye movements during visual imagery reflect the content of the visual scene. Results of this analysis indicate that spatial fixation patterns are not informative regarding the observer's task when pooling all data (on Greene et al. (2012). A., Itti, L.: Defending yarbus: eye movements reveal observers' task. Samaras D. Early in the viewing period, fixations were particularly directed to the faces of the individuals in the painting and observers showed a strong preference to look at the eyes more than any other features of the face. Iqbal S. 4. Two prominent yet contrasting hypotheses attempt to explain eye movements and attention in natural behavior. In Eye movements and vision . Successful task decoding results provide further evidence that fixations convey diagnostic information regarding the observer's mental state and task, We demonstrated that it is possible to reliably infer the observer's task from Greene et al. . Hybrid computer vision system for drivers' eye recognition and fatigue monitoring. Scheiter K. In. Itti L. Wiggins C. Van Hlse J. O'Connell T. Springer. (2013). (2003). 's (, In the second experiment, we showed that it is possible to decode the task using Yarbus's original tasks, almost twice above chance, much better than using Greene et al. Evidence of the anticipatory use of gaze in acquiring information about objects for future manipulation is provided, suggesting that visual information on the temporal and spatial structure of the scene was retained across intervening fixations and influenced subsequent movement programming. Bertram R. From eye movements to actions: How batsmen hit the ball. Koch C. Graph-based visual saliency. (2012) and contrary to their conclusion, we report that it is possible to decode the observer's task from aggregate eye-movement features slightly but significantly above chance, using a Boosting classifier (34.12% correct vs. 25% chance level; binomial test, p = 1.0722e 04). Bailey B. Zhang L. These analyses help disentangle the effects of image and observer parameters on task decoding. Lu B.-L. 's (. Hayhoe M. M. 's (, Three factors may have caused task prediction failure in Greene et al. On his well-known figure showing task differences in eye movements, Yarbus wrote "Eye movements reflect the human thought process; so the observer's thought may be followed to some extent from the records of eye movements" (Yarbus, 1967, p. 190) In other words, Yarbus believed that an observer's task could be predicted from his static . A comparison of selected simple supervised learning algorithms to predict driver intent based on gaze data. Can eye tracking be used as a form of biofeedback? For task decoding, the classification methods Random Forest, LDA, and QDA were used; features were fixation- or saccade-related measures. Boccignone G. This site uses cookies.

With respect to the third factor, we conduct the following two analyses: (a) pooling data from all observers over all images and tasks (i.e., 17 20 scan paths) and (b) treating each image separately. ARVO (1962-2015); The Authors (2016-present). Kyllingsbk S. (1998). Koch C. Wilming N. In 1963 Yarbus integrated, analyzed, and systematized the results of all his investigations up to 1962 that were rather briefly presented in Biofizika and in a number of other Russian publications.

We show that task decoding is possible, also moderately but significantly above chance (24.21% vs. 14.29% chance-level; binomial test, p = 2.4535e 06). (2013). However, while saccadic decisions are intensively investigated in instrumental contexts where saccades guide subsequent actions, it is largely unknown how they may be influenced by curiosity - the intrinsic desire to learn. (2009). monitor screen so that scenes subtended approximately 43 25 of visual angle. (2011).

From a broader perspective, we discuss techniques, features, limitations, societal and technological impacts, and future directions in task decoding from eye movements. Table 1. (1999). Land M. F. Reconsidering Yarbus: A failure to predict observers' task from eye movement patterns In 1967, Yarbus presented qualitative data from one observer showing that the patterns of eye movements were dramatically affected by an observer's task, suggesting that complex mental states could be inferred from scan paths. First, according to the cognitive relevance hypothesis, eyes are driven by top-down factors that intentionally direct fixations toward informative task-driven locations (e.g., in driving).

Participants sat 130 cm away from a 42-in. Zelinsky G. In a very influential yet anecdotal illustration, Yarbus suggested that human eye-movement patterns are modulated top down by different task demands. Understanding egocentric activities. Despite the volume of attempts at studying task influences on eye movements and attention, fewer attempts have been made to decode observer's task, especially on complex natural scenes using pattern classification techniques (i.e., the reverse process of task-based fixation prediction). Eye position predicts what number you have in mind. They convey a wealth of information regarding our mental processes. For instance, in Tatler et al. Indeed this has been elegantly demonstrated by seminal works of Guy T. Buswell (, Yarbus's results show striking differences in eye-movement patterns across instructions over the same visual stimulus. Zhang L. In this study, we perform a more systematic investigation of this problem, probing a larger number of experimental factors than previously. The prominence of behavioural biases in eye guidance. A brief biography of Yarbus is provided and his impact on contemporary approaches to research on eye movements, including interest in his work on the cognitive influences on scanning patterns is assessed. In it he recorded photographically the eye movements of 200 observers when looking at a wide variety of pictures. Pari G. Abstract: . . Kanan C. Zhang L.

We thus conclude that Yarbus's idea is supported by our data and continues to be an inspiration for future computational and experimental eye-movement research. Eye movements Multivariate pattern classication Yarbus Task abstract In 1967, Yarbus presented qualitative data from one observer showing that the patterns of eye move-ments were dramatically affected by an observer's task, suggesting that complex mental states could be inferred from scan paths. This article aims to draw readers attention to decision-making experimental paradigms supported with eye-tracking technology among clinical populations and may become an important component that will help in objectively illustrating patients models of beliefs and values, support clinical interventions, and contribute to health services.

The consistent inability to report on one's own eye movements across experiments suggests that awareness of eye movements is extremely impoverished or altogether absent, which is surprising given that information about priorEye movements is clearly used during visual search, motor error correction, and learning. Blair M. R. Reconsidering Yarbus: a failure to predict observers' task from eye Milanfar P. Jones W. This model provides a Bayesian, cognitive approach to top-down transitions in attentional set in pre-frontal areas along with vector-based saccade generation from the superior colliculus and demonstrates that the properties from its generated saccadic vectors closely match those of human observers given a particular task and cognitive state.
