Per a tip in the forum, N-Trig has posted a beta release of their N-Act software, a multi-touch gesture application that allows a user to switch windows, select text and images, and sweep through files.
The application was previously demoed by LAPTOP Magazine (YouTube video below). The software is for Windows 7, but hardware requirements are not listed, though presumably it only works with a N-Trig multi-touch digitizer. While the download page mentions the Dell Latitude XT and XT2 and HP TouchSmart tx2 Tablet PCs, that is for the other downloads listed on the page. I see no reason why it would not work on other N-Trig multi-touch systems, such as the Lenovo ThinkPad T400 and T410. Keep in mind though, those are Lenovo’s T Series touchscreen laptops; the X Series tablets uses Wacom. Yet another reason why it is increasingly important that vendors specify what digitizer they use.
Anyway, if you’re using an N-Trig multi-touch digitizer, you can give the beta software a thorough testing. If you give it a go, let us know what you think in the comments. I really like how it shows rings around the points of contact, showing cursors that aren’t obstructed by your fingertips. What do you think?
