Lernstift – The pen that vibrates when you make a mistake


The writing tool from Lernstift is capable of picking errors in spelling or letter formation in real-time, delivering a warning vibration to the writer’s hand. In calligraphy mode it can buzz the user when the letter shape is being created oddly, while in orthography mode it can be used to pick up spelling or grammar mistakes  (one buzz for spelling errors and two for grammar).  Error detection is only beginning of Lernstift’s history. Future versions will have various other features – e.g. a dynamic pressure sensor, a networking module to connect with PCs and other devices as well as an open platform for app development.

This could be an especially useful tool for students and those who are just learning how to write letters and words.
