How to simulate Touch event in Linux/Mac/Windows?

Question

Answer 1

Under Windows Vista and Windows 7, the Multi-Touch Vista drivers let you use 2 mice to simulate multi-touch gestures. It should degrade nicely to the "normal" touch experience. In my experience, it can be fairly tricky, but it works.

It really kind of depends on what you're working on and what the goal is. If you can separate the response from the action in your application, that will make it a lot easier to test something like this without going through a lot of hassle.

If you wind up needing a touch device, Wikipedia has a nice list of multi-touch devices.
