Lernstift (German for “learning pen”) is a digital pen with a difference, carrying not only ink inside its casing but also a tiny computer that alerts users to spelling errors. A pen which vibrates when it detects its user making a mistake is being tested in schools. The Lernstift does not require ink or special paper to work and uses an internal gyroscope to work out what is being written.

The AAA battery-powered Linux computer includes a vibration module and a patent pending non-optical motion sensor which recognizes specific movements and shapes of letters and words. Lernstift recognizes all writing movements, the company says, written on paper or in the air and built-in Wi-Fi allows scribblers to connect with smartphones, computers or other pens in a network.
A Kickstarter campaign recently got underway looking to raise £120,000 ($180,000). The first pens will initially recognize only English and German spellings, but other languages will follow, says its co founded Daniel Kaesmacher. Eventually, the company plan to offer pencil, fountain and ballpoint pen options with a launch price between €120-150 ($160-200) falling to under €50 ($60) depending on how fast the company grows.
