Ein Festnetztelefon für die Zielgruppe 65+


Nowadays, landline phones are packed with features. Unfortunately, the results are phones that are complicated to use. If you think of easy tasks like creating contacts, organizing voicemails, and looking for missed calls, the chance of finding the wanted result is nearly impossible. Especially users aged 65+ have tremendous difficulties in learning how to use interfaces and understand the meaning of buttons. Together with my colleague Katharina Brunkhorst, we created an entirely new way of interacting with a landline phone.

Contextual + physical buttons

SUMI defines a new standard in interacting with your landline telephone. One of the groundbreaking innovations in smartphones was the Multi-touch-Screen. Touching the content gives a sense of orientation in most modern Apps. While the use of touchscreens can unveil serious problems, especially for people with a lesser understanding of digital technology,
SUMI combines the remarkable capability to contextually change buttons, which can be pressed physically. Depending on the action you are about to execute, pressable display-keys help to understand your contextual options, and highlight their meaning with understandable icons.

While designing SUMI, the user’s feedback on prototypes was crucial. On a regular basis, target-group users at the age of 65+ were asked to give their opinion on dimensions, software capabilities, and UX design. As a result, we were able to enhance the product experience, leading to a positive user reaction.
