Wearable electromyography-based human-computer interface

A process for sending commands to one or more computing devices, comprising:

• arbitrarily positioning a wearable device in contact with an outer surface of a user's skin, said wearable device having a plurality of Electromyography (EMG) sensors for measuring muscle generated electrical activity via a skin of the user;
• providing automatic feedback to the user for directing the user to refine placement of the wearable device on a surface of the user's skin to position one or more of the sensors nodes to capture particular muscle generated electrical signals;
• automatically evaluating muscle-generated electrical signals of the user measured via one or more of the EMG sensors to automatically identify one or more specific gestures of the user from a predefined set of gestures;
• and
• automatically directing one or more computing devices to execute one or more specific commands corresponding to one or more of the identified gestures.

A system for providing a human-computer interface (HCI), comprising:

• an arbitrarily positionable wearable device having a plurality of sensor nodes, wherein each sensor node further includes one or more Electromyography (EMG) sensors;
• a device which provides automatic feedback to the user for directing the user to refine placement of a position of the wearable device on a surface of the user's skin to ensure adequate signal strength of the muscle generated electrical signals measured using one or more of the EMG sensors;
• a device for automatically measuring muscle generated electrical signals using one or more of the EMG sensors;
• a device for automatically determining which muscle generated electrical signals correspond to one or more specific user gestures;
• and
• a device for causing one or more computing devices to automatically execute one or more specific commands corresponding to one or more of the specific user gestures.
