German artist Lorenz Potthasts slow-motion helmet uses "sensory regeneration technology" to allow users to feel the world in slow motion.
There is a camera on the outside of the helmet, and a built-in computer is used to process the video signal captured by the camera, and then the slowed signal is displayed on multiple screens inside and outside the helmet. In other words, the computer processes the video signal captured by the camera and plays it back slowly. According to the users experience, it seems that the passage of time can really be forgotten in this helmet.
People can see the slow world perceived by the user from the external video screen.
