Using eye tracking to account for attribute non-attendance in choice experiments KU Leuven Universiteit Gent
© Oxford University Press and Foundation for the European Review of Agricultural Economics 2018; all rights reserved. This study uses eye-tracking measures to account for attribute non-attendance (ANA) in choice experiments. Using the case of sustainability labelling on coffee, we demonstrate various approaches to account for ANA based on the fixation count cut-offs, definitions for detecting ignored attributes, and methods for modelling ANA. ...
The use of eye tracking in landscape perception: influence of the horizontal and vertical view angle of observed landscape pictures Universiteit Gent
The European Landscape Convention states the need for public participation in landscape planning and management. Therefore, it is important to know how landscapes are observed by people, how distinct landscape features are perceived differently. This can be measured objectively using eye tracking technology, a system recording the speed and direction of eye movements (saccades) and fixations while observing images. Although, eye tracking is ...
Combined frequency-tagging EEG and eye tracking reveal reduced social bias in boys with autism spectrum disorder KU Leuven
Developmental accounts of autism spectrum disorder (ASD) state that infants and children with ASD are spontaneously less attracted by and less proficient in processing social stimuli such as faces. This is hypothesized to partly underlie social communication difficulties in ASD. While in some studies a reduced preference for social stimuli has been shown in individuals with ASD, effect sizes are moderate and vary across studies, stimuli, and ...
A comparison of visual identification of dental radiographic and nonradiographic images using eye tracking technology KU Leuven
OBJECTIVES: Eye tracking has been used in medical radiology to understand observers' gaze patterns during radiological diagnosis. This study examines the visual identification ability of junior hospital dental officers (JHDOs) and dental surgery assistants (DSAs) in radiographic and nonradiographic images using eye tracking technology and examines if there is a correlation. MATERIAL AND METHODS: Nine JHDOs and nine DSAs examined six radiographic ...
The use of eye tracking for analysing the perception of landscape composition and vertical objects Universiteit Gent
The European Landscape Convention states the need for public participation in landscape planning and management. Therefore, it is important to know how landscapes are observed by people, how they perceive different landscape features, to include this knowledge into landscape planning and design. This can be measured objectively using eye tracking technology, a system measuring the speed and direction of eye movements (saccades) and fixations ...
Equity Crowdfunders’ Human Capital and Signal Set Formation: Evidence from Eye Tracking KU Leuven Universiteit Gent Vlerick Business School
Signaling theory typically assumes that attention is always given to observable signals. We study signal receivers’ formation of signal sets—the signals to which receivers attend and that they can use for subsequent interpretations. Drawing on a cognitive perspective, we argue that signal receivers’ human capital influences the volume and type of signals they attend to and the time they take to form signal sets. Using eye tracking, we show that ...
A performance analysis of invariant feature descriptors in eye tracking based human robot collaboration Universiteit Antwerpen
For eye tracking applications in Human Robot Collaboration (HRC), it is essential for the robot to be aware of where the human gaze is located in the scene. Using feature detectors and feature descriptors, the human gaze can be projected to the image from which robot could know where a human is looking at. The motion that occurs during the collaboration may affect the performance of the descriptor. In this paper, we analyse the performance of ...
Sizing up numbers: Exploring individuals’ numerical magnitude understanding of natural and rational numbers using eye tracking KU Leuven
It is a well-established finding that the numerical magnitude of natural numbers (e.g., 250) is better understood than that of rational numbers (e.g., ¼ or 0.25; Vamvakoussi, Christou, & Vosniadou, 2018). Consequently, number type (i.e., natural vs. rational) can be regarded as source of difficulty in numerical magnitude understanding. However, research has shown, within the class of rational numbers, that the numerical magnitude ...
Application of visual servoing and eye tracking glass in human robot interaction Universiteit Antwerpen
Human gazes reveal a lot of information about their intention, which could be used for intuitive Human Robot Interaction(HRI). Using gaze as a modality to interact with robots has huge value in increasing freedom for human. It has a strong application potential in different domains. In this paper, we propose a system for eye tracking based HRI with which a human can select an object by his/her gaze and a robot manipulator receives the intended ...
