Automatic Synthesis of Haptic Audio

When you tap an object you can hear how hard it is, whether it is hollow and what it is made of. If you scratch or scrape it you can hear how rough it is, how bumpy, whether it has a regular texture. However most haptic objects don’t make a sound when you handle them. It’s as though you are in outer space.
