Abstract

This master's thesis investigates how people with visual impairment perceive light in urban environments and how lighting can better support their everyday mobility, focusing on train stations as common sites of stress. Motivated by a research gap that prioritizes indoor over outdoor lighting, the project examines how multisensory cues—especially touch and hearing alongside residual vision—shape spatial perception and wayfinding. The central question is how lighting qualities and configurations can enhance safe, legible, and comfortable station navigation for visually impaired users while also benefiting sighted users. The study adopts a human-centered, cross-disciplinary methodology: clarifying definitions and reviewing European rail accessibility standards (including PRM TSI); conducting natural science analyses (illuminance mapping, luminaire and material analysis); applying social science methods (walk-along interviews, obstacle analysis, and interviews with an occupational therapist and a mobility instructor); and integrating humanities and architectural perspectives through auditory and tactile analyses and movement mapping. Scenario testing is used to derive design criteria and inform a concept for inclusive urban lighting, potentially with intelligent features. Findings and final design outcomes are not presented in this excerpt.

Dette speciale undersøger, hvordan personer med synsnedsættelse opfatter lys i byrum, og hvordan belysning bedre kan understøtte deres daglige mobilitet, med særligt fokus på togstationer som en udbredt kilde til stress. Med afsæt i et forskningsgab, hvor udendørs belysning ofte overses til fordel for indendørs, belyser projektet, hvordan multisensoriske signaler – især berøring og hørelse sammen med restsyn – former rumopfattelse og orientering. Det centrale spørgsmål er, hvordan lyskvaliteter og -konfigurationer kan øge sikker, læsbar og behagelig navigation for synshandicappede og samtidig gavne seende brugere. Studiet anvender en menneskecentreret, tværfaglig metode: præcisering af definitioner og gennemgang af europæiske tilgængelighedsstandarder for jernbaner (bl.a. PRM TSI); naturvidenskabelige analyser (kortlægning af belysningsstyrke, armatur- og materialeanalyse); samfundsvidenskabelige metoder (gå-med-interview, forhindringsanalyse samt interview med en ergoterapeut og en mobilitetsinstruktør); samt humanistiske og arkitektoniske perspektiver gennem auditive og taktile analyser og bevægelseskort. Scenariotest bruges til at udvikle designkriterier og et koncept for inkluderende bybelysning, eventuelt med intelligente funktioner. Resultater og det endelige design fremgår ikke af dette uddrag.
