NaviGadget: Dutch inventors from Arnhem-Nijmegen University designed this indoor navigation system for those elderly people in nursing centers who seem to get lost a lot.
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.
