Relative cues and absolute distance perception.
I I t is possible, in theory, for the simultaneous occurrence of several different relative cues i of distances to increase the veridicality of the perception of absolute distance. To test whether I this actually occurs, a three-dimensional display was viewed monocularly while moving the head laterally, under conditions in which some error in perceived absolute distance was expected. The percei...
متن کاملDistance Perception and Cues to Distance in Virtual Reality
Distance perception in virtual reality is reviewed, and investigated in a series of experiments. In experiment 1, the systematic underestimation of distance found in virtual reality displays was investigated. This investigation used a video camera mounted on a head-mounted display to compare a photorealistic ”virtual” world to monocular viewing of the real world with restricted field of view an...
متن کاملThe necessity of a perception-action approach to definite distance perception: monocular distance perception to guide reaching.
In this investigation of monocular perception of egocentric distance, the authors advocate the necessity of a perception-action approach because calibration is intrinsic to definite distance perception. A helmet-mounted camera and display were used to isolate optic flow generated by participants' head movements toward a target, and participants' reaches to place a stylus either in a target hole...
متن کاملThe visual perception of size and distance.
The perception of absolute distance has been assumed to be important in the perception of the size of objects and the depth between them. A different hypothesis is proposed. It is asserted that perceived relative size and distance are the primary psychological phenomena with perceived absolute distance derived from the perceptual summing of perceived relative depths. In agreement with this poin...
متن کاملHow Haptic Size Sensations Improve Distance Perception
Determining distances to objects is one of the most ubiquitous perceptual tasks in everyday life. Nevertheless, it is challenging because the information from a single image confounds object size and distance. Though our brains frequently judge distances accurately, the underlying computations employed by the brain are not well understood. Our work illuminates these computions by formulating a ...
