An indirect measure of perceived distance from oculomotor cues

Tool use influences perceived shape and perceived parallelism, which serve as indirect measures of perceived distance.

Targets presented just beyond arm's reach look closer when observers intend to touch them with a reach-extending tool rather than without the tool. This finding is one of several that suggest that a person's ability to act influences perceived distance to objects. However, some critics have argued that apparent action effects were actually due to effects on the judgments rather than on the perc...

An XML Distance Measure

Distance measures are used extensively in data mining and other types of data analysis. Such measures assume it is possible to compute for each pair of domain objects their mutual distance. Much of the research in distance measures concentrates on objects either in attribute-value representation or in first-order representation. With the increasing use of XML technology as a means for unambiguo...

Revision of a fuzzy distance measure

A comparison of oculomotor and motion parallax cues of egocentric distance.

Using the head motion procedure, the apparent distance of a point of light in an otherwise dark visual field was measured under conditions in which oculomotor cues (accommodation, convergence) and absolute motion parallax were varied together and separately. It was concluded that absolute motion parallax is almost as effective a cue to distance as are oculomotor cues from monocular observation,...

Do visual cues contribute to the neural estimate of viewing distance used by the oculomotor system?

Perceived shape and depth judgments that require knowledge of viewing distance are strongly influenced by both vergence angle and the pattern of vertical disparities across large visual fields. On the basis of this established contribution of visual cues to the neural estimate of viewing distance, we hypothesized that the oculomotor system would also make use of high-level visual cues to distan...
