A new robotic device helps piano players improve their finger skills after just 30 minutes of use, scientists report.
The study, published in Science Robotics, tested a robotic glove that moves pianists' fingers without them having to try. Players showed better control of their fingers after using the device.
The robot helped musicians play difficult piano techniques better. It improved their ability to perform complex finger movements like trills, where two notes are played very quickly one after another.
The device works by moving the pianist's fingers in specific patterns. This helps train their muscles and brain to remember these movements later.
"The results show how robots might help people learn physical skills faster," the researchers noted in their paper.
Musicians didn't have to practice actively while wearing the robotic hand. They just let the device move their fingers through the proper motions.
The study focused on experienced piano players. However, researchers think the technology could help others too.
The robotic hand might help people recovering from injuries. It could also assist patients working to regain movement after stroke or other medical conditions.
Scientists continue to study how robots can help people learn physical skills. This research shows promising results for both musicians and medical patients.
The team plans to test the robotic hand with different groups of people. They want to see if it can help with other types of movement training.
