Lernstift -digital pen that can check for spelling mistakes in handwriting

Lernstift - SMART PEN................

Now, smart pen that vibrates when you make spelling error.

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 is a regular pen with real ink or you can change it to a pencil, but inside is a special motion sensor and a small battery-powered Linux computer with a WiFi chip.

Together those parts allow the pen to recognize specific movements, letter shapes and know a wide assortment of words. If it senses bad letter formation or messy handwriting, it will vibrate.

Users can choose between two functions:
Calligraphy Mode - pointing out flaws of form and legibility
or
Orthography Mode - recognizing words and comparing the word to a language database.

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.
