Discomfort Glare: - Focus on understanding discomfort glare - Embedding eye‐movement patterns in glare assessments - Refining glare position index. Problem: - The light of sight in glare position index is assumed to be fixed - In a natural experience, line of sight varies through time and space - This variation is due to light distribution and spatial configuration. How In an Experimental setting: - Subjective ratings and objective parameters are measured - Experiments are carries out in realistic and controlled work space.
