Me and my sister do live in different cities. She was quite old, but did not want any help from strangers. She did refuse to use a computer keyboard, since she hated informatization, and her sight was short.

So I did automate a system for her to scan the guests documents, detect the data required by local police for registration via OCR, fill up the form to send those data, and update the web site availability database table. The computer, when powered up, did only show instructions in big text, high contrast instructions, which where repeated by TTS (essentially "please feed the documents in the scanner", "please remove the documents from the scanner").

At the end she got used to using it, and she was quite proud being able to be so independent, since the last days of her lovely life.
