In most cases it is not the users fault. The products User Interface Design is to blame. In this bachelor thesis, #25. principals for designers and developers have been developed to prevent user from resignation. The focus is on Best-Agers as target group, because they are and will be a huge share in the German market, due to their growth.

The field of attention is to increase the User Interface quality by taking user interaction barriers into account. In the thesis, it will be explained, what the User Interface quality is, how it is measured, how the user processes informations, which user interaction barriers are known and which ones are relevant
for Best-Agers. The principles are based on these user interaction barriers, to give advice for the User Interface Design and the development process. Afterwards there is a list showing which principal is to use for certain specific user interaction barriers. The finishing chapter is valuating the principals and is a look ahead regarding User Interface Design.
To ease the access to the principals on a daily base, three placates have been designed for developers and designers. They are intended to be hung up in the office to check UI-, Information- and UX-design for improvement.
