Il navigatore da polso… degli anni 1920
Il primo navigatore della storia è questo “orologio” con mini mappe arrotolate da scorrere durante il viaggio: Plus Fours Routefinder
Invented in 1920′s this could be world’s first navigation system. No satellites or digital screens were used in the making of this portable navigation system.
Called Plus Fours Routefinder, this little invention was designed to be worn on your wrist, and the “maps” were printed on little wooden rollers which you would turn manually as you drove along.
The device was intended to allow drivers to navigate around the UK, but with so few cars on the roads it never really took off.
Now consigned to the scrap heap of history, the Routefinder is one of many gadgets patented by inventors who were hoping to strike it rich with their bizarre contraptions.
It’s part of a collection of weird and wonderful inventions, all conceived between 1851 and 1951, which have gone on display at the British Library in London.
