This software was developed to help the visually impaired to see who is calling on the landline. A possible setup would be using a Raspberry Pi and an USB modem.
The main part of the program only shows the last 4 callers and if being called the current caller. Everything is setup as big as possible on a fixed 1024x768 resolution with high contrast. The only input used is the scroll-wheel to mark the last called numbers as seen.
The program runs on node.js supported by some libraries.
