Intervention type: DEVICE
Group type: EXPERIMENTAL
Intervention: Motion and Emg Control
Description: We will consider two methods for integrating motions and EMG signals:~1. Direct methods. Signals extracted from the latent EMG space will directly contribute to the control of the external device. We will integrate EMG and IMU in two ways. In a first scenario, EMG and IMU will be given variable weight in the control. In a second scenario (perturbative method) the distance of ongoing muscle patterns from a desired set of strategies will modulate the mapping from body to cursor motions in the form of assistive (i.e. the cursor moves faster towards the target) or resistive (i.e. the cursor slows down) influences on cursor movement.~2. Indirect Methods. Signals extracted by EMG will modulate the feedback offered to the learner to penalize deviations from desired muscle patterns. When multiple ways to perform a movement are offered by redundancy, (i.e., by the multiplicity of muscles compared to task demands), the brain chooses solutions that minimize noise and uncertainty.
