Tutorial: Theoretical considerations when planning research on human factors in lighting

YAW de Kort - Leukos, 2019 - Taylor & Francis
Research on human functioning is notoriously difficult. This particularly holds for the study of
light effects, at least if one wants to go beyond establishing that changes in light “have an …

[HTML][HTML] Functional vision barriers: A new concept analyzed in terms of human visual performance.

EM Colombo, BM O'Donell, JE Santillán… - Psychology & …, 2013 - psycnet.apa.org
In this work we introduce a new category of barriers that we call “functional vision barriers.”
This expression refers to lighting and visual elements that may complicate or hinder …

Pupil light reflex produced by glare under mesopic adaptation

E Colombo, SA Comastri, L Issolio… - Journal of Light & Visual …, 2007 - jstage.jst.go.jp
The amount of light captured by the eye depends on pupil size. Moreover, one of the factors
determining the steady-state pupil size is ambient ilfumination and sudden increments of …

Effect of glare on simple reaction time

RC Aguirre, EM Colombo, JF Barraza - JOSA A, 2008 - opg.optica.org
We systematized the study of the effect of glare on reaction time (RT), for visual conditions
similar to the ones found during night driving: Mesopic range of adaptation (0.14 cd/m^ 2) …

Pupil dynamics with periodic flashes: effect of age on mesopic adaptation

B Silva, A Sfer, MA D'Urso Villar, LA Issolio… - Journal of the Optical …, 2016 - opg.optica.org
The purpose of this study is to determine the pupillary dynamics with periodical flashes from
a peripheral glare source, in similar conditions to night driving, while focusing on …

Evaluation of the intraocular scattering through brightness reduction by glare using external diffusers to simulate cataracts

PA Barrionuevo, EM Colombo… - 2010 - notablesdelaciencia.conicet.gov.ar
In this work, we evaluate the feasibility to determine the intraocular scattering by measuring
the brightness reduction by glare. A haploscopic system based on the brightness …

Retinal mesopic adaptation model for brightness perception under transient glare

PA Barrionuevo, EM Colombo, LA Issolio - JOSA A, 2013 - opg.optica.org
A glare source in the visual field modifies the brightness of a test patch surrounded by a
mesopic background. In this study, we investigated the effect of two levels of transient glare …

Estudio de la medida de la difusión intraocular con un nuevo parámetro basado en el análisis de imágenes de doble paso en el dominio de las frecuencias.

M Estrada Asensio - 2018 - upcommons.upc.edu
Objetivo: Validar un nuevo parámetro para la medida de la difusión intraocular basado en el
análisis de imágenes de doble paso en el dominio de las frecuencias (FSI, Frequency …

Veiling luminance as a descriptor of brightness reduction caused by transient glare

LA Issolio, PA Barrionuevo, SA Comastri, EM Colombo - JOSA A, 2012 - opg.optica.org
The presence of a glare source in the visual field produces a veiling luminance (L_v), which
generates a brightness reduction that can be expressed in terms of the glare index (V). The …

Robot navigation control using vision based steering wheel

MQ Do, CH Hung, CH Lin - Multimedia Tools and Applications, 2017 - Springer
Human-robot interaction has recently drawn great attention in both academic and industrial
communities. Given the benefit features of human-robot interaction, this article developed a …
