Light Intensity and Depth Perception

Depth perception from point-light biological motion displays.

Humans have a clear impression of facing in depth for point-light biological motion. However, this has not been measured systematically nor is it known on which cues humans rely for their judgment. In the present study subjects judged the facing orientation-in-depth of point-light displays. The displays represented natural walking and modified versions in which the time sequence was reversed, a...

Depth perception

Depth perception.

Glossary Cue The signal or information in a two-dimensional image that can be used to infer or reconstruct the spatial relations in a three-dimensional scene. Depth Refers to the distance between a viewer and an object as well to the distance between two objects that extend away from a viewer. This is the missing dimension when depicting a three-dimensional scene in a two-dimensional image, whe...

Intelligence, intensity, depth, vision,

The use of sensor arrays, embodied in electronic noses, to characterize complex samples is anactive and dynamic expression of research in chemical sensors. In this review, we emphasizesensors, instrumentation, and applications aspects of electronic nose technology. In addition, wehave added to the existing historical description of electronic nose development, projected likelydi...

Depth Perception, Cueing, and Control

Humans rely on a variety of visual cues to inform them of the depth or range of a particular object or feature. Some cues are provided by physiological mechanisms, others from pictorial cues that are interpreted psychologically, and still others by the relative motions of objects or features induced by observer (or vehicle) motions. These cues provide different levels of information (ordinal, r...
