Digital pen that helps kids learn to write
The electronic pen will vibrate to signal an illegible letter or misspelled word.
The pen will function in either calligraphy mode (vibrating when a letter is written incorrectly) or orthography mode (vibrating to signal a spelling or grammar error). Future generations of the pen will include pressure sensors and a network module to transfer data 'written' with the pen to digital devices.
