A pair of German inventors have created a digital pen that can check for spelling mistakes in handwriting.
The Lernstift, which is German for learning pen, has a built-in sensor that recognises writing movements and tracks the shape of the letters to recognise words. It then vibrates when a mistake is made.
Lernstift also has Wi-Fi built-in and the pen can be connected a smartphone or PC to upload written texts online, share them on social networks or take part in writing training
