Solutions

Design assumptions

1. A home is a living environment, not a technical object.
2. Accessibility arises from real user experiences.
3. The home and technology are to compensate for limitations.
4. Design takes place in parallel with evaluation from three perspectives.
5. The home is a system, not a sum of independent solutions.
6. Technology is a tool, not a goal.
7. Everyday use is the ultimate evaluation criterion.
8. The project takes into account variability in health and a long time horizon.
9. The project is open and replicable in nature.
10. The goal of the project is a real improvement in quality of life.

Criteria for evaluating solutions

• Usability from the perspective of a wheelchair, crutches, and non-vision.
• Reduction of user burden (physical and cognitive).
• Predictability and repeatability of operation.
• Sensory accessibility and clear feedback.
• Resilience to reduced ability and “worse days.”
• System integration and the possibility of central control.
• Verification in real, everyday use.

Decision map

The project is also defined by what we consciously do not implement.

• “Formally accessible” solutions that do not work in practice.
• Exclusively visual interfaces without an audio or tactile alternative.
• Technologies that are impressive but burden the user.
• One-dimensional solutions—working only for one perspective.
• Closed and unverifiable systems, without integration and control.

Accessibility Living Lab

We test solutions in a real home, in everyday use. This allows us to verify ergonomics, safety, and repeatability in practice.
