Abstract EN
Background.
The surface electromyogram (sEMG) is strongly related to human motion and is useful as a human interface in robotics and rehabilitation.
The purpose of this study was to establish a new system for estimating finger joint angles using few sEMG channels.
Methods.
To deal with a dynamic system, the proposed method adopts time delay factors and a feedback stream into a neural network (NN) with 6 system parameters.
The 2 target motion patterns were each tested with 5 subjects.
1000 combinations of system parameter sets were tested.
Results.
A system with only 4 channels can estimate angles with 7.1–11.8% root mean square (RMS) error, which is approximately the same level of accuracy achieved by other systems using 15 channels.
Conclusions.
The use of so few channels is a great advantage in an sEMG system because it provides a convenient interface system.
This advantage is conferred by the proposed NN system.
