I was lucky enough recently to be involved in a Surface project at Microsoft writing an educational game for an upcoming "trade show". I can really see how the collaborative nature and natural interaction of the Surface could be huge in the education space, I really can't get excited by touch or multi-touch on a "normal" machine. I can ...
I have an EeePC 900 running Ubuntu Intrepid Ibex. The touchpad has some simple multi-touch gestures built in - scrolling by dragging with two fingers instead of one for example. How would I detect multi-touch events in an OpenGL/C application? Is the touchpad on the EeePC 900 capable of handling rotational and scaling gestures? Th...
Hi, I develop a collaborative business application on a multi-touch device like Microsoft Surface. However to my mind every collaborative application on a multi-touch device was made to share photos, to draw, to play, or for one person at time.

Anyone out there developing for this, or know what the environment is?

You know how Mario just keeps running to the right when you press and hold the right-button on the D-Pad? In the same manner, I want my UIButton to continuously fire its action for the duration that it is held down. Is this possible for a UIButton? If not, is this possible to do with a UIImageView by overriding a touch handling method in...

After a period of iPhone work, I'm once again working on normal Cocoa apps on my MBP and I miss the "tap" gesture. I know that I can turn on the incredibly annoying "Tap to Click", feature in the Trackpad control pannel, but I don't want a click, I want a tap. I know it's probably not mac canon, but is it possible to receive this multi-...

We would like 2 code samples (C# would be great) of Windows 7 multitouch functionality using .NET 3.5 sp1 and the ManipulationProcessor: A two finger click sample – An event should be raised when a user “clicks” on a UIElement such as a Rectangle using 2 fingers simultaneously (Close together). The click event should be fired when the...
