We determined the foveal Stiles-Crawford Effect as a function of up to 8 D accommodation stimulus in 6 young emmetropes and 6 young myopes using a psychophysical two-channel Maxwellian system in which the threshold luminance increment of a 1mm spot entering through variable positions in the pupil was determined against a background formed by a 4 mm spot entering the pupil centrally. The SCE bec...

Spatiotopic cues, such as perceived distance, have little effect on accommodation unless blur has been reduced or eliminated. We investigated the effect of perceived distance on accommodation under binocular steady-state conditions, about which little is known. Blur was reduced but not eliminated by using a stimulus with a moderately low luminance. Accommodation was measured under two condition...

In this paper, an adaptive accommodation control for complex assembly is presented. The complex assembly (CA) is defined as a task whose wsembled parts have complex geome~ including concavity. The concept of the adaptive accommodation, which is inspired by the insertion operation of a blindfold human, is to adaptively change the accommodation property depending on the sensed contact wrench and ...

AIM To study accommodation in relation to different refractive errors, amblyopia and to measure the anatomical changes in the accommodating eye MATERIALS AND METHODS We studied the amplitude of accommodation (AA) in 150 patients in the age group 11 ± 30 years which included emmetropes, myopes, hypermetropes and hypermetropic amblyopes using the Royal Air Force (RAF) rule. The anterior chamber...

PURPOSE A reduced sensitivity to retinal image blur has been reported in myopes. Diminished blur detection reduces the error signal to the retinotopic (blur-induced) accommodation system and results in impaired accommodation responses under retinotopic conditions. This study was conducted to investigate retinotopic accommodation responses in emmetropia and myopia under dynamic conditions. MET...

Jointly working on shared digital artifacts – such as wikis – is a well-tried method of developing knowledge collectively within a group or organization. Our assumption is that such knowledge maturing is an accommodation process that can be measured by taking the writing process itself into account. This paper describes the development of a tool that detects accommodation automatically with the...

Peer-to-peer (P2P) accommodation rentals continue to grow at a phenomenal rate. Examining how this business model affects the competitive landscape of accommodation services is of strategic importance to hotels and tourism destinations. This study explores the competitive edge of P2P accommodation in comparison to hotels by extracting key content and themes from online reviews to explain the ke...

Accommodation is considered to be important by institutions interested in mental health care both in Australia and internationally Some authorities assert that no component of a community mental health system is more important than decent affordable housing. Unfortunately there has been little research in Australia into the consequences of discharging people with a primary diagnosis of schizoph...

Psycholinguistic phenomenon of communication accommodation (Giles et al., 1991) is probably one of the most important contributions in the interdisciplinary field of linguistics, psychology, information, and communication theory. Existing works have applied this theory to various domains like gesture, linguistics, backchannels, and even social media like tweets. In this work, we analyze the psy...
