Pen that detects spelling error

Jul 15, 2013 |

German inventors have developed a new hi-tech pen that gently vibrates every time it senses a spelling mistake or sloppy handwriting.

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, “ABC News” reported on Sunday. Users can choose between two functions: Calligraphy Mode — pointing out flaws of form and legibility or Orthography Mode.
