Based on my interest in interactive drawings, and previous experiments with flash and archicad, I now make some trials with svg. I had to make some changes for the iPad version as a response to the touch- istead of the mouse-interaction. I distinguish between three types of interaction, which in some cases can be combined. Feedback, when the drawing responds to a touch event with some information or a change in appearence; indirect, when interface elements mediate between touch actions and drawing responses; and direct, if the drawing is directly manipulated.

  Feedback – example 1

  Indirect – example 2
