A Pen that vibrates when you make a mistake while writing – Lernstift

A unique digital pen points out spelling errors with a subtle vibration to help kids (and adults) acquire better writing skills!

Spellcheck can be pretty frustrating, but it’s become an invaluable feature in word-processing programs. For jotting down notes with a pen, though, people just have to take their lumps. Or, rather, they did; a new project on Kickstarter, created by two German dads, hopes to improve spelling around the world by alerting scribes whenever they make an error.

2 Primary Function:

1. Orthography Mode – to recognize spelling errors
– for writing starters (5-8 yrs) + everyone (7-99 years)

2. Calligraphy Mode– to point out flaws of form and legibility
– for writing starters 5-8 yrs (7-99 yrs in Asia)

Using a motion sensor that combines a gyroscope with an accelerometer, the Lernstift smart pen will be able to capture and monitor the user’s handwriting, vibrating whenever a word is spelled incorrectly. The pen was conceived by co-creator Falk Wolsky’s wife, who hit upon the idea after helping her son with his homework.

Features:

The computer inside Lernstift is an embedded Linux system
The board contains motion sensor, processor, memory, Wi-Fi and vibration module.
the sensor delivers a resolution of ~400 dpi at 200 Hz.
