Our project is implementing controlling an electronic prosthetic hand created by Haifa3D using head gestures. The goal is to provide an easy-to-use and affordable product solution for amputees, using simple and daily movements.
An inertial sensor, MPU6050, is located on the user’s head. When using the system, the sensor is reading the user’s head movements, and the controller sends the appropriate movement command to the hand. Tilting the head left or right will turn the hand in the same direction, and moving the head up will open or close the hand. Also, as safety mechanisms, the system requires the user to tilt their head downward to “unlock” it—minimizing the risk of unintended hand movements—and it automatically locks again after a preset timeout period if no movement is detected.
This intuitive control system is designed to seamlessly fit into the user’s daily routine, making the prosthetic hand easier, safer, and more natural to use.
