We also thank Dicky N. Sihite for his help on parsing the eye-movement data. 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. 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. Garcia-Diaz A. We followed a partitioned experimental procedure similar to Greene et al. Ullman S. 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. Brandt S. A. In Eye movements and vision . (2010). Eye movements and the control of actions in everyday life. Acronyms are: intensity (I), color (C), orientation (O), entropy (E), variance, t-junctions (T), x-junctions (X), l-junctions (L), and spatial correlation (Scorr). '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. Using eye gaze patterns to identify user tasks. Eye-Tracking; Procedural tree; Saliency . In the first experiment, we reanalyze the data from a previous study by Greene et al. Torralba A.

Olejarczyk J. Tavakoli H. R. 227: 2013: Revisiting Video Saliency: A Large-scale Benchmark and a New Model. Two prominent yet contrasting hypotheses attempt to explain eye movements and attention in natural behavior. Kietzmann T. Zhang L. Attention to eyes is present but in decline in 2-6-month-old infants later diagnosed with autism. (2010) the results obtained by Yarbus were confirmed in an experiment that studied the effect of instructions in viewing a portrait of Yarbus. (2001). Jang Y.-M. Poynter W. Mast F. On comparing classifiers: Pitfalls to avoid and a recommended approach. Just recently, we noticed that another group (Kanan et al., Is it always possible to decode task from eye movements? Jutta Hild, Elisabeth Peinsipp-Byma, and Edmund Klaus. All Holdings within the ACM Digital Library. Alfred Lukyanovich Yarbus ( ; 3 April 1914 in Moscow - 1986) was a Soviet psychologist who studied eye movements in the 1950s and 1960s.. Yarbus pioneered the study of saccadic exploration of complex images, by recording the eye movements performed by observers while viewing natural objects and scenes. Kster F. Cottrell G. W. Viewing task influences eye movement control during active scene perception. In. Hyn J. We provide a brief biography of Yarbus and assess his impact on contemporary approaches to research on eye movements. Strauss B. 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. In Eye movements and vision . However, there is of course a large body of work examining top-down attentional control and eye movements using simple stimuli and tasks such as visual search arrays and cueing tasks (e.g., Bundesen, Habekost, & Kyllingsbk, Due to important implications of Greene et al. (1997). Zhang L. Kingstone A. A theory of eye movements during target acquisition. Eye movements reveal the time-course of anticipating behaviour based on complex, conflicting desires. Static and space-time visual saliency detection by self-resemblance. Kwak H.-W. Bundesen C. 14, 3 (2014), 29--29. . Kowler, E. (1990). Tsotsos J. 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). Kanan C. Helle L. The strong claim of this very influential finding has never been rigorously tested. Predicting eye movements in multiple object tracking using neural networks. Eye movements reveal fast, voice-specific priming. Copyright 2022 ACM, Inc. Hayhoe M. Saliency from hierarchical adaptation through decorrelation and variance normalization. (1989). Trivedi M. M. (1960). 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. You can manage this and all other alerts in, Eyes are windows to perception and cognition. Watson M. R. Greene MR, Liu T, Wolfe JM. Eye movements reveal epistemic curiosity in human observers, Reconsidering Yarbus: A failure to predict observers task from eye movement patterns, An inverse Yarbus process: Predicting observers task from eye movement patterns. Eye movements reveal epistemic curiosity in human observers. Eye movement patterns are found to reveal human cognitive and mental states that can not be easily measured by other biological signals. Kuhn G. O and T stand for observer and task, respectively. Koch C. The information available in brief visual presentations. Quantitative analysis of human-model agreement in visual saliency modeling: A comparative study. 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 . (2012). (2012). Salzberg S. (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). Fathi A. Gelade G. Land M. F. Clark J. J. Hoffman L. 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. Predicting an observer's tasks from eye movements during several viewing tasks has been investigated by several authors. Luke S. Betz T. (1998). Bailey B. J. Vis. Mennie N. Coraggio P. Beecher G. P. Regarding the first factor, we use a simple feature that is the smoothed fixation map, down sampled to 100 100 and linearized to a 1 10,000 D vector (Feature Type 1). (1997). Hoffman A. Freund Y. 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. Reconsidering Yarbus: A failure to predict observers' task from eye movement patterns. The link between eye movements and visual perception is so tight that perception is facilitated even during the preparation of eye movements [1-5]. (, We train a RUSBoost classifier (with 50 boosting iterations) on 16 observers over each individual image and apply the trained classifier to the remaining observer over the same image (i.e., leave one observer out). Our code and data is publicly available at. Clark J. J. Here, a RUSBoost classifier (50 runs) was used over all data according to the analysis in the section Task decoding over all data). What/where to look next? Samaras D. What do we learn from the two experiments in this study? . In stark contrast, the published material in English concerning his life is scant. He found that an observer's eye movement patterns during freeview were dramatically different. Verbrugge R. Saliency, attention, and visual search: An information theoretic approach. Your gaze betrays your age. It is concluded that information about a people's search goal exists in fixation behavior, and that this information can be behaviorally decoded to reveal a search target-essentially reading a person's mind by analyzing their fixations. Expertise in pictorial perception: Eye-movement patterns and visual memory in artists and laymen. Sihite D. N. 's (, Three factors may have caused task prediction failure in Greene et al.

's, Task decoding accuracy highly depends on the stimulus set. 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 .

(2007). In a very influential yet anecdotal illustration, Yarbus suggested that human eye-movement patterns are modulated top down by different task demands. Seo H. . It is demonstrated that viewing task biases the selection of scene regions and aggregate measures of fixation time on those regions but does not influence other measures, such as the duration of individual fixations. Spontaneous eye movements during visual imagery reflect the content of the visual scene. We perform two experiments. Itti L.
