Together with elderly people, a system for the notification of medication intake and measuring the blood pressure has been developed. This system consists of a hardware part, displaying different visual signals to remind users, and a software part to configure the hardware accordingly. Those visual signals are displayed with the help of a lamp, which can be placed in the living room or at any other desired place. The colors of those signals can be adapted with the help of an application, where the time and medication can be configured to be displayed. The developed software was created following a user centered design process together with four elderly people to get to know their needs and to identify the key requirements for such a system.
