Embodiments provide techniques for automating control of electronic device. A first interactive game playing within the physical environment using one or more electronic devices is detected. Embodiments collect electromyogram data from one or more electromyography sensors within the physical environment and analyze the electromyogram data collected to determine muscle activations made by the user. Upon determining that the determined muscle activations made by the user match a predefined pattern of electromyography data, embodiments determine a gameplay action corresponding to the predefined pattern of electromyography data and transmit an instruction, to at least one of the one or more electronic devices within the physical environment, instructing the electronic device to perform the determined gameplay action.

The present invention relates to a device and system to measure and assess superficial skeletal muscle mechanical and neuromuscular contractile characteristics, and interpret the results to provide metrics with quantifiable and qualitative descriptors relating to muscle function. The present device provides a further type of mechanomyography and a new use for acceleromyography by measuring the mechanical muscle movement of an involuntary stimulated muscle from an automated electro-stimulation protocol to determine muscle contractile properties. Muscle twitch response during the latent, contraction and relaxation phase is measured using an array of multiple accelerometers on a sensor pad to assess and diagnose muscle. function from various measurements. This information is processed using algorithms to determine muscle function abnormalities, muscle activation patterns, muscle symmetry of lateral muscle pairs, muscle synchronization of antagonist muscle, muscle force, muscle acceleration, muscle speed, muscle tone, muscle fatigue, muscle power/torque and muscle efficiency.

An exercise feedback system monitors the performance of athletes wearing a garment with sensors while exercising. The sensors generate physiological data such as muscle activation data, heart rate data, or data describing the athlete's movement. The system extracts features from the physiological data and compares the features with reference exercise data to determine metrics of performance and biofeedback. Based on the physiological data, the system may also modify exercise training programs for the athlete. The exercise feedback system can display the biofeedback using visuals or audio, as well as modified exercise training programs, via the athlete's client device in real time while the athlete is exercising. By reviewing the biofeedback, the athlete may correct the athlete's exercise form to properly use the target muscles for the exercise, or change the certain workouts to personalize the training program.

Local swing leg control was developed that takes advantage of segment interactions to achieve robust leg placement under large disturbances while generating trajectories and joint torque patterns similar to those observed in human walking and running. The results suggest the identified control as a powerful alternative to existing swing leg controls in humanoid and rehabilitation robotics. Alternatively, a detailed neuromuscular model of the human swing leg was developed to embody the control with local muscle reflexes. The resulting reflex control robustly places the swing leg into a wide range of landing points observed in human walking and running, and it generates similar patterns of joint torques and muscle activations. The results suggest an alternative to existing swing leg controls in humanoid and rehabilitation robotics which does not require central processing.
