Smart pen

Now, smart pen that vibrates when you make spelling error. Lernstift is a regular pen with real ink, 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 recognise 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 recognising words and comparing the word to a language database.
