How can a service listen for touch gestures/events?

阅读更多关于 How can a service listen for touch gestures/events?

I'm wondering how apps like SwipePad and Wave Launcher are able to detect touch gestures/events simply through a service. These apps are able to detect a touch gestures even though it is not in their own Activity. I've looked all over the Internet and haven't found how they can do that. My main question is how a service can listen in on touch guestures/events just as a regular Activity may receive MotionEvents even though it may not be in the original Activity or context. I'm essentially trying a build an app that will recongize a particular touch gesture from a user regardless which Activity

How to recognize swipe gesture in UIScrollView

阅读更多关于 How to recognize swipe gesture in UIScrollView

I'm trying to recognize left/right swipe gesture in a UIScrollView . I've tried to create UISwipeGestureRecognizers and associate them with the scroll view. It works but very rarely. Most of the time I do not get called. Why? How can I reliably get swiping left/right to work? Can I use the gesture recognizers or do I have to somehow handle it myself in touchesBegan/Ended Thanks David Figured it out. In my case, my UIScrollView contained a UIImage that I allowed zooming. Apparently that meant that scrolling is enabled and the UIScrollView had trouble distinguishing between gestures intended to

Is there a way to trigger gesture events on Mac OS X?

阅读更多关于 Is there a way to trigger gesture events on Mac OS X?

问题 I want to trigger multitouch gesture events on Mac OS X. Is there a way to do this? Mouse or keyboard events can be triggered with CGEventCreateMouseEvent and CGEventCreateKeyboardEvent. Is there similar low level function for multitouch events? Rok Your suggestion is not working. I've tried this code: - (void)rotateWithEvent:(NSEvent *)event { NSLog(@"ROTATE"); } -(IBAction)button:(id)sender { CGEventSourceRef eventSource = CGEventSourceCreate(kCGEventSourceStateCombinedSessionState);

Comparing a saved movement with other movement with Kinect

阅读更多关于 Comparing a saved movement with other movement with Kinect

问题 I need to develop an application where a user (physiotherapist) will perform a movement in front of the Kinect, I'll write the data movement in the database and then the patient will try to imitate this motion. The system will calculate the similarity between the movement recorded and executed. My first idea is, during recording (each 5 second, by example), to store the position (x, y, z) of the points and then compare them in the execution time(by patient). I know that this approach is too

How to make an Android view that flips between views on swipe/fling

阅读更多关于 How to make an Android view that flips between views on swipe/fling

I'd like to make a view in my Android app that flips between multiple views on a swipe/fling. I'd like it to behave more or less like the Android Launcher behaves when flipping between views. In particular, It should flip views on swipe. Generally a swipe will flip between one view and the next. It should not fling across all of the views. If you swipe slowly, you should see the views dragging as you're swiping, eg. the way the Launcher does it. I tried using a ViewFlipper with a GestureOverlayView as per Romain Guy's blog post here , but there's no indicator to the user as they're swiping.
