Mobile Full Body Haptic Resistance Rig with Touch-able Air Blast Free Space Projection Hologram:

A robotic suit suspended in air that you can wear in order to only allow movement in the space outside of virtual objects that also includes 3D virtual objects made by pointing a projector wherever you want it to appear and a gun that shoots air at the fingers of anyone else whenever they touch a virtual object, so that you can feel the full physical weight and hardness the objects on any part of your body while on the go and give the illusion of touching said object to anyone around you.
