I liked this project:
https://tangible.media.mit.edu/project/recompose/
The project utilizes gestural movements similar to the Soli, yet 10 years prior and with real objects responding in physical characteristics rather than a computer program on a screen. The precision and control that the user can impose these shapes reflect a more precise version of soli’s tap function, allowing them to shape the height of the cuboid landscape. This also allows a more natural “pinching” gesture to indicate pulling up the surface below. I think this some ideas of how to approach soli.
