This is an indoor navigation system for those elderly people in nursing centers who seem to get lost a lot, it designed by Dutch inventors from Arnhem-Nijmegen University.

Instead of relying GPS signals which provide poor or no coverage indoors this system uses Wi-Fi to get a position fix. Keeping in mind the computer skills of people over 55 this experimental navigator was only fitted 5 buttons. As far as user interface they used big icons for things such as ‘bathroom’ or ‘cup of coffee’ to help them navigate throughout the building.
