“Touch it, try to press. Guess what it is. And how it could look like”. The co-designing of the remote control took place in three different locations to improve an important part of the smart accessible toilet.

Previous research has shown that the user-friendliness of remote controls is still not up to standard. So we needed an input from the experts – elderly people and people with mobility restrictions, the primary users of the future toilet system. An interactive sessions with creative activities and group discussion helped us to find best solutions for the hand control. We know it should be simple, clear and visible. Colours help to make clear what is meant and a pictogram with a figure is more legible than an abstract graphic. Buttons should not be close to each other but apart and SOS button as well as STOP button are key elements. The project staff is still analyzing the results to give more recommendations to the technical partners.
