Ottobock Myo Plus pattern recognition

In order to use the Myo Plus prosthesis control in the best possible way, it can be customized via an app. The biggest challenge in control is the similarity of individual patterns. Since many hand movements differ only by nuances, the Myo Plus pattern recognition system must recognize and correctly assign a large number of different patterns. After an initial configuration by an orthotist, the prosthesis wearer has the option of using the app to train communication with the prosthesis. For this purpose, the measured movement patterns are transmitted to a smartphone or tablet and visualized ( Video). The initial training to use the new controller takes a few days, depending on the patient. Once communication between the user and the prosthetic controller is working, the user can save the progress in the app and readjust it themselves. In addition, users can adjust the speed of the hand and the speed of rotation.

During the development of the configuration and training app, the blue-zone team was able to support Ottobock's developers in the areas of conception, implementation, optimization, verification and documentation, thus making a valuable contribution to this great product.
