UIST'09: Ripples: Per-Contact Visualizations for Touch Displays

[omniambience]

Actually, when not hitting something, the trace should not be bigger when actually hitting something

I like surface computing but not surface lag - note the lag when moving things around and the trace graphics is lagging behind the fingers actual position, this is not good - feedback needs to be real-time and accurate

Hi, is there any chance we can download and test your ripples on a Windows 7 installation with multitouch devices? This is something I'd love to touch!

Couldn't you add a coaster program to ripple that say allows someone to draw a circle with there finger and then they can place objects in that area of the table without it effecting there other programs? they could still manipulate it with there fingers if they wanted to change its size or throw it off screen to delete it. Also for things like the arm activating objects, you could make it so that only objects of within two centimeters can active them so most accidental brushes wont effect it.
