Understanding the Role of External Feedback in Motor Learning using EMS and Robotic Actuation

Description

When learning complex motor skills-like playing piano or dancing -we refine our movements over time through repetition and conscious correction. Neuroscience suggests that this process relies on internal execution and reflection. However, recent findings challenge this view: a study using Electrical Muscle Stimulation (EMS) showed that externally actuating corrective movements can enhance both performance and learning. This project investigates a key question: Is it the muscular stimulation or the external actuation that drives learning? You'll explore this by comparing EMS-based feedback with robotic physical guidance using our custom setup that includes a Novint Falcon haptic device, dual EMS systems, and Unity3D. The work will involve building interactive scenarios, conducting controlled user studies, and analyzing behavioral outcomes.
