Handwriting is a fundamental skill, but even the best writers make mistakes. Munich-based innovators Daniel Kaesmacher and Falk Wolsky have developed Lernstift, a pen that vibrates to notify users of spelling errors as they write.
The concept emerged when Wolsky’s wife questioned why their son couldn’t have a pen that highlighted his mistakes automatically. This led to the creation of a pen that integrates handwriting recognition software, comparing each written word to a built-in dictionary and providing immediate feedback through gentle vibrations.
Beyond its primary function, Lernstift is designed with an embedded Linux system, motion sensors, a processor, memory, Wi-Fi capabilities, and a vibration module.
The founders are also opening the platform to developers via an open API, envisioning a range of applications from educational games to real-time collaborative writing tools. The project is currently seeking support on Kickstarter, with a funding goal of $183,000 to commence full-scale production.
