Holograms that you can Feel?

I thought that this was something of interest. The article “From sci-fi to science lab: Holograms you can ‘feel’” describes a holographic system called Multimodal Acoustic Trap Display (MATD) which “can simultaneously deliver visual, auditory and tactile content”. This uses “acoustophoresis” to move and manipulate particles to create the hologram.

This work was written up in the article “A volumetric display for visual, tactile and audio presentation using acoustic trapping” that appeared on11/13/19 in Nature. This could bring some very interesting interactive displays in the future.
