Saliency, Attention, Active Visual Search, and Picture Scanning

John G. Taylor, Vassilis Cutsuridis
2011 Cognitive Computation  
How the decision is made when to terminate a fixation and move the gaze? How the decision is made where to direct the gaze in order to take the next sample?  ...  The special issue starts with a paper by Mital, Smith, Hill, and Henderson who investigated the contribution of low-to mid-level visual features to gaze location during free viewing of a large dataset  ...  Similarities between visual search patterns are essential to characterize the stereotypical visual behavior of observers and thus, expert knowledge.  ...

Pupil diameter differentiates expertise in dental radiography visual search

Nora Castner, Tobias Appel, Thérése Eder, Juliane Richter, Katharina Scheiter, Constanze Keutel, Fabian Hüttig, Andrew Duchowski, Enkelejda Kasneci, Susana Martinez-Conde
2020 PLoS ONE  
Our aim was to measure pupil diameter response to anomalies of varying levels of difficulty in expert and student dentists' visual examination of panoramic radiographs.  ...  However, certain tasks could still evoke different gradations of load even for an expert, e.g., when having to detect subtle anomalies in dental radiographs.  ...  In such tasks, expert visual inspection is derived from domain knowledge and is optimized for a short period of search.  ...

Visual search: psychophysical models and practical applications

Guang-Zhong Yang, Laura Dempere-Marco, Xiao-Peng Hu, Anthony Rowe
2002 Image and Vision Computing  
During visual search for a de®ned target, there is evidence for both parallel search, with which all objects are processed concurrently, and for sequential search, in which several ®xation points are found  ...  The purpose of this paper is to highlight some of the key opportunities for the image and vision computing community and promote further interactions between biological and computational vision research  ...  During a visual search, a saccade moves the gaze of the eye to look at the current area of interest.  ...

Eye Movements and Word Recognition during Visual Semantic Search: Differences between Expert and Novice Language Learners

Irina V. Blinnikova, Maria D. Rabeson, Anna I. Izmalkova
2019 Psychology in Russia: State of Art  
This study focuses on the cognitive strategies used by expert and novice language learners in a visual semantic search task.  ...  The registration of eye-movement patterns in visual semantic search tasks reveals the characteristics of effective and non-effective cognitive strategies used by ESL students at different levels of language  ...  In searching for a reliable answer, we attempted to compare eye movements in more and less successful trials.  ...

Task and user effects on reading patterns in information search

Michael J. Cole, Jacek Gwizdka, Chang Liu, Ralf Bierig, Nicholas J. Belkin, Xiangmin Zhang
2011 Interacting with computers  
One of the contributions of this research is a new methodology to model information search behavior and investigate information acquisition and cognitive processing in interactive information tasks.  ...  For each participant we classified eye gaze data to construct models of their reading patterns.  ...  During search in both experiments, all of the participants' interactions with the computer system, including eye gaze, were logged.  ...

Adolescents' Developing Sensitivity to Orthographic and Semantic Cues During Visual Search for Words

Nicolas Vibert, Jason L. G. Braasch, Daniel Darles, Anna Potocki, Christine Ros, Nematollah Jaafari, Jean-François Rouet
2019 Frontiers in Psychology  
In both experiments, participants' search times decreased from fifth to ninth grade, both because older adolescents gazed less often at non-target words during the search and because they could reject  ...  Two eye-tracking experiments were conducted to assess the influence of words either looking like the target word (orthographic distractors) or semantically related to the target word (semantic distractors  ...  to the Center for Research on Cognition and Learning.  ...

Expectations and memory in link search

Antti Oulasvirta, Lari Kärkkäinen, Jari Laarni
2005 Computers in Human Behavior  
We argue that practice-related decreases in reaction time were caused by semantic priming. Roles for the different types of memory in link search are discussed.  ...  Strategies in searching a link from a web page can rely either on expectations of prototypical locations or on memories of earlier visits to the page.  ...  The first author gratefully acknowledges grants from Elisa Communications and the Academy of Finland.  ...

Linking search tasks with low-level eye movement patterns

Michael J. Cole, Jacek Gwizdka, Ralf Bierig, Nicholas J. Belkin, Jingjing Liu, Chang Liu, Xiangmin Zhang
2010 Proceedings of the 28th Annual European Conference on Cognitive Ergonomics - ECCE '10  
One limitation is a lack of knowledge about the general reading model differences across different types of tasks in the population.  ...  Specifically we show that transitions between scanning and reading behaviour in eye movement patterns are an implicit indicator of the current task.  ...  During the search, all of the participants' interactions with the computer system, including eye gaze, were logged.  ...
