Recent research conducted by scientists in Japan has revealed the critical role that the speed of movement plays in the perception of robotic prosthetics equipped with artificial intelligence. In the study, participants evaluated their sense of ownership, effectiveness, and social perceptions regarding the robotic arm based on its movement speed. This research highlighted how both very slow and very fast movements could reduce the users' sense of embodiment and, consequently, their evaluation of the prosthetic as a useful tool.

The implications of this study extend beyond mere technical specifications. Researchers utilized virtual reality environments to simulate various movement speeds, allowing them to assess users' reactions more effectively. The balance between autonomous and controlled movement of the prosthetic is essential for its functionality and could inform future designs to make these devices feel more like a natural extension of the body. This research represents a significant contribution to the field of prosthetics design, merging technology with neuropsychology.

As the demand for advanced prosthetics increases, addressing the challenges faced by designers regarding the brain's natural expectations will be pivotal. The findings of this study could lead to better integration of AI in prosthetic devices, enhancing user experience and acceptance. By understanding how the brain perceives robotic limbs, designers can create more intuitive and user-friendly products that meet the needs of individuals who rely on these life-changing technologies.
