Enter the Lernstift, a Linux powered pen that gives a subtle vibration when you make an error. The pen’s orthography and calligraphy modes are perfect for children learning to write and you won’t even need an app or computer to power the artificial intelligence behind the tiny computer. Parents can also keep an eye on their child’s learning using the pen’s optional app that tracks data on learning statistics. Since the pen is digital, it can also be programmed to share documents and sketches via its co-writing platform or through social media for school curriculum
