German new pen recognizes writing errors

German new pen recognizes writing errors

German scientists invented a new type of pen that recognizes errors and reminds its users during writing.

It is reported that a special sensor is installed in the pen to distinguish the running trajectory of the pen tip when the user writes, thereby determining whether or not a writing error has occurred. The pen will alert the user to the error in the form of vibration. And such a smart pen looks no different from a regular pen.

According to the report, the original intention of designing this pen was to help German lower grade students learn word spelling. At present, the market price of pens and the time to market have not been determined.
