Creating tactile focal points in a specific 3D coordinate seems possible if we use the transducers described in this video. You can see that they are able to "place" tactility in specific 3D location. https://www.youtube.com/watch?v=2QkbVr4J7CM https://www.youtube.com/watch?v=2QkbVr4J7CM All that would be needed here would be an AR solution that projects an opaque hologram of a 3D object in the same location where tactility is being placed in mid air. What stops us from increasing the power of the transducers as to magnify the torque, pressure? Like parent's comment: anvil vs basketball. What is a safe and realistic range of pressure for anvil? Could such virtual object injure the user if dropped?
