Control system and user interface for prosthetic devices

A method of operating a prosthetic device, the method comprising:

• receiving first sensor data based on first myoelectric signals detected by a first sensor;
• receiving second sensor data based on second myoelectric signals detected by a second sensor;
• determining a resultant vector using the first sensor data and the second sensor data;
• causing display of a user interface comprising a multi-dimensional plot corresponding to a posture map, the posture map defining an association between one or more boundary regions and one or more posture definitions used to control movement of the prosthetic device,
• causing display of a dynamic graphical icon on the multi-dimensional plot indicating a current correlation of the resultant vector with respect to the one or more boundary regions of the posture map;
• receiving a user input changing a location of at least a portion of a first boundary region within the multi-dimensional plot;
• and
• updating the posture map based on the change to the location of the portion of the first boundary region.

A prosthetic device comprising:

• a first sensor configured to detect myoelectric signals at a first location of a user;
• a second sensor configured to detect myoelectric signals at a second location of the user;
• memory storing a posture map defining a correlation between one or more boundary regions defined by first and second component dimensions and one or more posture definitions used to control movement of the prosthetic device, the one or more boundary regions comprising:
• a first boundary region defining a first posture definition;
• a second boundary region defining a second posture definition;
• and
• a buffer region separating the first boundary region and the second boundary region and defining a region of the posture map that does not correspond to a posture definition;
• and
• a controller configured to:
• receive first sensor data based on the myoelectric signals detected by the first sensor;
• receive second sensor data based on the myoelectric signals detected by the second sensor;
• and
• determine a resultant vector using the first sensor data and the second sensor data;
• determine an intended posture definition based on mapping the resultant vector with respect to the posture map;
• and
• cause the prosthetic device to perform one or more operations associated with the intended posture definition.
