how to make three-dimensional objects completely touch sensitive

Projects Discussion and Showcase Interactive Art
3

well, the metal-surface I am going to use is already conductive.

the question is rather how to detect -

1)if it got touched (simple capacitive sensing)

  1. where exactly the three-dimensional surface got touched (the main problem!).

mabe also 3) how it got touched (http://www.disneyresearch.com/research/projects/hci_touche_drp.htm)

The second and third task cannot be performed onboard, I will trie to use PureData fot that.

Thanks for replies!
