Perceiving Affordances through Perceptual Information
The purpose of this study was to explore how users perceive the affordances of an object from specific operation tasks. These affordances can be specified in terms of perceptual information. To this end, the eye-tracking technique was employed to capture what product parts uses’ fixation focused on when using a product for specific operational tasks. The results show that, for physical-behavior...
متن کاملPerceiving affordances for fitting through apertures.
Affordances--possibilities for action--are constrained by the match between actors and their environments. For motor decisions to be adaptive, affordances must be detected accurately. Three experiments examined the correspondence between motor decisions and affordances as participants reached through apertures of varying size. A psychophysical procedure was used to estimate an affordance thresh...
متن کاملPerception of maximum stepping and leaping distance: Stepping affordances as a special case of leaping affordances.
Successfully performing everyday behaviors requires perceiving affordances-possibilities for behavior that depend on the fit between environmental properties and action capabilities. Whereas affordances for some behaviors are primarily constrained by relatively static geometric properties of the perceiver (non-launching behaviors such as stepping), others are additionally constrained by dynamic...
متن کاملPerceiving, Learning, and Exploiting Object Affordances for Autonomous Pile Manipulation
Autonomous manipulation in unstructured environments presents roboticists with three fundamental challenges: object segmentation, action selection, and motion generation. These challenges become more pronounced when unknown manmade or natural objects are cluttered together in a pile. We present an end-to-end approach to the problem of manipulating unknown objects in a pile, with the objective o...
متن کاملMemory for the functional characteristics of climbing walls: perceiving affordances.
In 2 experiments, differences in visual perception of climbing routes (route finding) between 7 expert climbers, 4 novices, and 9 inexperienced participants were studied. In both experiments, participants reproduced on a scale model the locations and orientations of 23 holds of a climbing wall. The results showed that the expert climbers recalled more information and recalled clusters of inform...
