As I mentioned earlier, Windows 7 is something to think about, in particular when it comes to support for multi-touch. My question was if SDK will be ready by that time or even earlier, since some models of the laptops support MT mode even today.
BetaNews just published an article about Windows 7 multi-touch SDK being readied for PDC in October.
From PDC 2008 agenda:
Windows 7: Touch Computing
In Windows 7, innovative touch and gesture support will enable more direct and natural interaction in your applications. This session will highlight the new multi-touch gesture APIs and explain how you can leverage them in your applications.
Let’s keep watching for more stuff to come.
Update: PDC video are available now.
