Hilde Ehrle presses a light switch. A green LED strip lights the floor, running across the apartment: From the bedroom with the nursing bed, through the living room, past the kitchen with height-adjustable countertops, and into the accessible bathroom. “Green light is especially good for orientation at night, as the brain doesn’t react as sensitively to this frequency,” Hilde explains to an elderly couple listening closely. She then walks in her bright sneakers along the green line from room to room, the couple following behind.
For over ten years, Hilde Ehrle has been volunteering to advise visitors at the LebensPhasenHaus, a two-story building on the outskirts of Tübingen. Researchers from the university work here together with guests, the district seniors’ council, local trade businesses, and enterprises from the medical engineering, pharmaceutical, and electrical industries to test ideas for independent living for seniors or people with physical or cognitive disabilities.
Since 2015, the LebensPhasenHaus has opened its doors every Friday. In the last five years alone, about 3,000 interested people and caregivers have visited.
