A wearable eye tracker was used to record photographers' eye movements while they took digital photographs of person, sculpture, and interior scenes. Eye movement sequences were also recorded as the participants selected and cropped their images on a computer. Preliminary analysis revealed that during image capture people spend approximately the same amount(More)

In adjusting a gray square in an image to appear achromatic, observers spent 95% of their time looking only at the patch. When subjects looked around (less than , not achromatic regions, indicating that people do not seek(More)
Eye tracking has long held the promise of being a useful methodology for human computer interaction. However, a number of barriers have stood in the way of the integration of eye tracking into everyday applications, including the intrusiveness, robustness, availability, and price of eye-tracking systems. To lower these barriers, we have developed the(More)
Visual perception, operating below conscious awareness, effortlessly provides the experience of a rich representation of the environment, continuous in space and time. Conscious visual perception is made possible by the 'foveal compromise,' the combination of the high-acuity fovea and a sophisticated suite of eye movements. Our illusory visual experience(More)
We explore the way in which people look at images of different semantic categories (e.g., handshake, landscape), and directly relate those results to computational approaches for automatic image classification. Our hypothesis is that the eye movements of human observers differ for images of different semantic categories, and that this information can be(More)
Currently, developmental psychologists rely on paradigms that use infants' looking behavior as the primary measure. Despite hundreds of studies describing infants' visual exploration of experimental stimuli, researchers know little about where infants look during everyday interactions. Head-mounted eye-trackers have provided many insights into natural(More)
Visual perception is an inherently complex task, yet the bulk of studies in the past were undertaken with subjects performing relatively simple tasks under reduced laboratory conditions. In the research reported here, we examined subjects' oculomotor performance as they performed two complex, extended tasks. In the first task, subjects built a model rocket(More)
In studying image quality and image preference it is necessary to collect psychophysical data. A variety of methods are used to arrive at interval scale values which indicate the relative quality of images within a sample set. The choice of psychophysical technique is based on a number of criteria, including the confusion of the sample set, the number of(More)
Ubiquitous, high-resolution, large public displays offer an attractive complement to wearable displays. Unfortunately, the inherently public nature of these public displays makes them unsuitable for displaying sensitive information. We present EyeGuide, a wearable system that allows the user to obtain information quickly from a public display without(More)
