1. Regional specialization within the triple compound eyes of the gonodactyloid stomatopod Conodactylus oerstedii (Hansen) was studied by examining how ocular tracking of a small target was affected after occluding vision in particular ommatidial regions with black enamel paint. 2. Complete occlusion of one eye did not prevent the other eye from tracking, indicating that the two eyes act somewh...

Although eye tracking is a method able to reveal cognitive processes that cannot be measured with approaches such as surveys or direct observation, its use in consumer research is uncommon and primarily restricted to the measurement of attention. This paper analyzes the application of eye tracking in marketing and consumer research thus far, and identifies more innovative ways in which eye trac...

The effect of an attentional manipulation on eye tracking dysfunction (ETD) in the early stages of schizophrenia was examined in 34 recent-onset schizophrenic patients and 24 demographically matched normal subjects over a 1-year period. An attentional enhancement manipulation improved eye tracking performance of recent-onset schizophrenic patients more than that of normal subjects. Eye tracking...

Several visualization methods for eye tracking data exist to help researchers from many disciplines depict data collected in eye tracking experiments. Focusing on eye tracking data from observations of cartographic lines, in this paper we propose a new visualization of eye tracking data using polylines inferred from the analysis of samples. This visualization depicts the “average” line that is ...

Multi-modal interactions have long been explored as a way to improve user experience. With the development of mobile eye-tracking technology, the advantages of using multiple input modes can be applied to mobile eye-tracking applications. The paper introduces a platform for development of mobile eye tracking called Ogle; along with a key feature it possesses the ability to develop multimodal in...

In user studies, eye tracking is often used in combination with other recordings, such as think-aloud protocols. However, it is difficult to analyze the eye tracking data and transcribed recordings together because of missing data alignment and integration. We suggest the use of word-sized eye tracking visualizations to augment the transcript with important events that occurred concurrently to ...

Since eye tracking was first introduced by Mowrer in 1936, it has been gaining in popularity over the past decades as a window into observers’ visual and cognitive process. For instance, researchers have utilized eye tracking to study behavior in such domains as driver fatigue detection (Qiang et al., 2004; Horng et al., 2004; Dong et al., 2004 ), eye typing for helping users with movement disa...

Abstract One difficulty with sketching pedagogy is the tendency to assess growth according outcomes, as opposed processes. We assessed eye gaze patterns between advanced and intermediate design sketchers anticipated correlations eye-gaze practices proficiency. Participants sketched two different objects using analogue materials, a potted plant from memory, MacBook observation. The study utilise...

The problem of eye gaze tracking has been researched and developed for a long time. The most difficult problem in the non-intrusive system of eye gaze tracking is the problem of head movements. Some of existing methods have to use two cameras and an active infrared (IR) illumination to solve this problem. Otherwise, with a single camera, the user has to hold the head uncomfortably still when pe...

Eye-tracking is a valuable research tool that is used in laboratory and limited field environments. We take steps toward developing methods that enable widespread adoption of eye-tracking and its real-time application in clinical decision support. Eye-tracking will enhance awareness and enable intelligent views, more precise alerts, and other forms of decision support in the Electronic Medical ...
