This preliminary study introduces a novel method for providing proprioceptive feedback in prosthetic control using a compact solution with 8 vibro-motors, which is then compared to a traditional method with 12 motors splitted in 2 arrays. The novel approach employs Gaussian interpolation for distributing the stimuli across a single motor array (Compact feedback) to convey wrist rotation and hand aperture. Tested on ten able-bodied subjects using pattern recognition for controlling a 2-DOF hand, both Compact and Conventional feedback methods showed comparable accuracy and time efficiency in a target achievement task. Results indicate that the novel feedback strategy is effective and intuitive, while requiring fewer motors, thereby demonstrating potential for amputees’ application.

摘要

This preliminary study introduces a novel method for providing proprioceptive feedback in prosthetic control using a compact solution with 8 vibro-motors, which is then compared to a traditional method with 12 motors splitted in 2 arrays. The novel approach employs Gaussian interpolation for distributing the stimuli across a single motor array (Compact feedback) to convey wrist rotation and hand aperture. Tested on ten able-bodied subjects using pattern recognition for controlling a 2-DOF hand, both Compact and Conventional feedback methods showed comparable accuracy and time efficiency in a target achievement task. Results indicate that the novel feedback strategy is effective and intuitive, while requiring fewer motors, thereby demonstrating potential for amputees’ application.
