The importance of the research field, physical environment and the effects on people’s well-being, is highlighted since the report of Ulrich 1978. However, since this topic has an influence on a large amount of people, the difference between people gives the topic its multifaceted aspect. Which means many different angles on this topic have not been research yet or are still lacking research data. Notably the people who are sick and/or injured (hospital patients), are confined inside hospital patient rooms while they recuperate. The effect of relevant factors of view to the outside and the daylight parameter on the visual perception of patient, which influence patients’ wellbeing and recovery, is still lacking in research. This led to the research question of this graduation project paper: Which relevant factors related to the view to the outside and/or to daylight parameters influence the visual perception of people?
