In the video, a man is seen standing on a stage with a TEDx logo in the background. He is wearing a white shirt and has a prosthetic arm. The man is demonstrating the functionality of the prosthetic arm by moving his fingers and making gestures. He points to his prosthetic arm, opens and closes his hand, and moves his fingers individually. The prosthetic arm appears to be made of a shiny, metallic material, and the man's movements are smooth and controlled.
