For example, if an image does not have the necessary content that is called for by different tasks (in an extreme case, a blank image and tasks about age or wealth of people), it may not yield task-dependent eye-movement patterns as strong as an image that has such content. 1935. Here, a RUSBoost classifier (50 runs) was used over all data according to the analysis in the section Task decoding over all data). Hagemann N. Methods: Thirty-two elderly people with healthy vision (median age: 70, interquartile range [IQR] 64-75 years) and 44 patients with a clinical diagnosis of . Pushing deeper into real-time scenarios, using joint online analysis of video and eye movements, we have recently been able to predictmore than one second in advancewhen a player is about to pull the trigger in a flight combat game, or to shift gears in a car racing game (Peters & Itti. Itti L. The prediction confidence level of each task-dependent model is used in a Bayesian inference formulation, w , 23 . Vis. 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.

This is often referred to as the saliency hypothesis (Itti, Koch, & Niebur, Yarbus showed a proof of concept with a single observer but did not conduct a comprehensive quantitative analysis. Sihite D. N. Pardo X. M. 2012; 62 (C):1-8. Navalpakkam V. 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. In a very influential yet anecdotal illustration, Yarbus suggested that human eye-movement patterns are modulated top down by different task demands. Saliency detection: A spectral residual approach. (2012). A theory of eye movements during target acquisition. . The list of studies addressing task decoding from eye movements and effects of tasks/instructions on fixations is not limited to the above works. Folk C. L. Wang J. The early eye tracking studies of Yarbus provided descriptive evidence that an observer's task influences patterns of eye movements, leading to the tantalizing prospect that an observer's intentions could be inferred from their saccade behavior.

Visuomotor characterization of eye movements in a drawing task. (2010). (2000). This study demonstrates that task decoding is not limited to tasks that naturally take longer to perform and yield multi-second eye-movement recordings, and shows that task can be to some extent decoded from the preparatory eye- Movements before the stimulus is displayed. 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). Tatler B.

Magicians use misdirection to manipulate people's attention in order to prevent their audiences from uncovering their methods. Further, Yarbus's experiments point towards the active nature of the human visual system as opposed to passively or randomly sampling the visual environment. Treisman A. Ramsay G. Interestingly, the patterns observed might partially differ from those in natural eye-hand coordination, probably due to limited confidence in robot behavior.

This active aspect of vision and attention has been extensively investigated by Dana Ballard, Mary Hayhoe, Michael Land, and others who studied eye movements in the context of natural behavior. Goal-directed and stimulus-driven determinants of attentional control. These analyses help disentangle the effects of image and observer parameters on task decoding. 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).

Feature Type 3 resulted in accuracy of 0.3414 (see, Average task decoding performance per image using Feature Type 3 is illustrated in, Easiest and hardest stimuli for task decoding in, Results of the second analysis support our argument that image content is an important factor in task decoding. Epelboim J. Table 1. Griffiths A. N. Oliva A. Memory representations in natural tasks. In 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). Alfred L Yarbus. Renninger L. W. Kster F. Hsiao J. H. 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. 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 (2012) argued against it by reporting a failure .

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. Nature. (2008). 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. J. Here, we showed that task is decodable on static images by a more systematic and exhaustive exploration of the parameter space including features, classifiers, and new data.

Observers were in the age range of 1924 (mean = 22.2. . This is particularly important since both Yarbus and Greene et al. Martinez-Conde S. Yarbus' claim to decode the observer's task from eye movements has received mixed reactions. 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.

Defending Yarbus: Eye movements reveal observers' task ALI BORJI, LAURENT ITTI UNIVERSITY OF SOUTHERN CALIFORNIA Robino C. (2012). 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. Since the parameter space is large, making strong arguments regarding impossibility of task decoding (see, e.g., Greene et al. Recognition of human's implicit intention based on an eyeball movement pattern analysis. Modeling top-down visual attention in complex interactive environments. In a very influential yet anecdotal illustration, Yarbus suggested that human eye-movement patterns are modulated top down by different task demands. S. Ramanathan, H. Katti, N. Sebe, M.
