Take a stick and a telephone pole or something that can serve as an obstacle (a whole is also something and the lack of ground or sound can tell you a lot about what is around you) and work with a partner using a stick to check how you can use the stick to control him with this feature and how he can use this to avoid harm and keep moving. Move slowly at least at first so you learn from this and go up and down with the speed so you learn to be aware of it and be able to act despite the speed or lack of it of an attacker or partner.
