Very old people often have problems with mental abilities, touch and vision. When the phone rings it is real issue to figure out what button to press and hit the right one to pick up the call. It is easy to end up in random phone menus instead that are incomprehensible for the elderly.

Here is solution for the problem in the form of 3D printed case and extra add-on button that is glued to the original dial/receive key of the phone. All other buttons are rendered inaccessible on purpose.

For extra clarity, this one important button:

• Is painted red.
• Has exaggerated surface and relief raising above main case surface.
• Has big white circle around it (I used airbrush with stencil to paint the circle).
