To make an environment as safe and manageable as possible, not just family members but also architects and planners need to learn to see the world through the eyes of the people living there. Anyone can change their perspective. They only need to be willing to use a degree of empathy to see, hear and feel the world as others do. If they can do this successfully, they will be better able to recognize and grasp the demands everyday life can make. That is why the participants of the workshop “colour and light in architecture” held at the Bavarian Institute of Architecture for the elderly and cognitively impaired in Bamberg, have tested a pair of glasses simulating an eye cataract while walking on differently coloured surfaces.
