A digital pen to help clean up handwriting and spelling errors was developed by scientists.
The brainchild of two German entrepreneurs, 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 recognize specific movements, letter shapes and know a wide assortment of words.
If it senses bad letter formation or messy handwriting, it will gently vibrate.
The goal is also to make it smart enough that when you misspell a word it will vibrate as well.
Daniel Kaesmacher, the 33-year-old co-founder of Lernstift, which means 'Learning Pen' in German, told ABC News that the pen will have two functions-calligraphy and orthography mode.
He said that when it comes to orthography mode-the pen will be able to recognize words and compare the word it recognized to a language database. If the word isn't recognized it will vibrate.
