Research and its applications, medium-term and long term
I think the first step would be to create a physics-based model of the environmental conditions so that you really can computationalize it in a database from any viewpoint of what the illumination...

Appendix C: Previous Research on the Visibility of Detectable Warning Surfaces
The study was conducted indoors with artificial illumination of approximately 215 lux (20 fc) (it varied along the testing platform from 135 lux (12.5 fc) to 264 lux (24.5 fc)....

Issue 9: What are the top research topics that need to be undertaken (i.e., Identification of R&D Opportunities)?
But, I mean, for an office environment, one watt a square foot, that’s very difficult to provide a quality illuminated environment that addresses low-vision issues, provides appropriate...
