This patent survey are for no intrusion on existing patents should occur and give new ideas. The next step was generate concepts from a morphological matrix that has been evaluated from knowledge and experience. The concepts that were interesting to work further on have been made as small scale models, and new thoughts and ideas grown from there.The concepts and ideas that have been further investigated have been built in large scale prototypes. These prototypes have been tested on users on a community centre for the elderly and the staff working there. The final result will be created as a final prototype. This is a wish from the company and lay outside the master thesis.
