AI Decodes Mechanical Keyboards by Ear
Machine learning on microcontrollers has been a hot topic for the past several years, but most of the projects we see are still pretty simple, like keyword spotting or gesture recognition. Psychogenic Technologies shows just how far these tiny devices have come by building two very different edge AI projects: one that can identify which key was pressed on a mechanical keyboard simply by listening to it, and another that transforms a pair of boxing gloves into wireless motion controllers capable of recognizing punches in real time.
Both projects are built around Nordic Semiconductor's Edge AI ecosystem, but they demonstrate two different approaches to running neural networks on embedded hardware. One relies on dedicated AI acceleration, while the other shows that, for the right workload, even a modest processor is capable of getting the job done.
