One day, while scrolling through the internet, I came across a video that stopped me in my tracks. It was about a man with no arms who had undergone surgery to move nerves into his pectoral muscles. This transformation enabled him to control two prosthetic limbs. But there was a catch – he couldn\’t take […]
The Journey of Open Muscle: Democratizing Assistive Technology Read More »
We are excited to announce that our innovative finger tracking sensor, Open Muscle, has been submitted to the Supply Frame contest on hackaday.io. Open Muscle is a device designed to track finger movements, making it a valuable tool for building computer interface devices or controlling prosthetic hands. It consists of a wrist cuff (forearm band)
After obtaining initial results, I conducted further studies on myself to ensure that the random forest regressor was not simply memorizing the data. I employed a method that involved starting two separate sessions for open muscle and LASK data capture, but only fed one of them into the model. During the training process, I kept
