Many seniors want to use digital devices more independently, but complex interfaces, missing feedback and fear of making mistakes often create insecurity. As a result, they frequently depend on relatives or helpers for everyday digital tasks.
The goal was to develop a supportive system that helps seniors navigate digital applications step by step, while building confidence and digital independence.
Through expert and user interviews, feature prioritization and two rounds of usability testing, the concept was iteratively adapted to the needs, fears and learning habits of the target group.
The result is Mia, a digital assistant with a physical button, starter package and learning app that guides users through digital processes in a clear, contextual and reassuring way.
