"AIREAL pumps out tight vortices of air to simulate tactility in three dimensional space. The idea is to give touchless experiences like motion control a form of physical interaction, offering the end user a more natural response through, well, touch." It looks like Aireal can only create a pulsing sensation, which will still be insufficient for sculpting, and I imagine it is a weak sensation in the first place, but I am still interested to see how these technologies improve over time.
