Using webcam to track hand gestures

老子叫甜甜 提交于 2019-12-03 16:08:05
I wanted to develop a program which uses the webcam to track four colours and which are going to be on my index finger and thumb of both my hands and according to the gestures of my hand the computer will interpret these gestures and carry out a command. For example if I have a website open, all I have to do is pinch with my fingers and the webpage will zoom. I wanted the advice of the stackoverflow community as to where to start and whether anyone has any advice for me. Thanks in advance.

How to use Android Map to zoom with hand gesture (iphone like)

Deadly 提交于 2019-12-03 15:58:17
How do you use the Android API to zoom in and out maps with the 2 finger gestures like iPhone? Android doesn't currently officially support multitouch. There's been some work by various people (Your google for 'android multitouch' is as good as mine), but nothing in the official android distro or APIs yet. A relevant blog post just showed up in my feedreader with more particulars. UPDATED: As of Android API Level 5 (aka Android 2.0), Android does have a multi-touch API. Support for it is, of course, browser-specific. You need to override the MapActivity's OnTouchEvent() with something like

Disabling Pan Gesture if out of bounds detected

江枫思渺然 提交于 2019-12-03 15:53:11
I have a UIView I am trying to move up and down the screen, however I only wish to enable it to pan so that you cannot drag the view down when it is in its normal position (0, 0) I tried to detect when the recognizer's center is not half the height of the view, however the view is then immovable, and the center is always half the height (230 in this case). Any ideas? - (IBAction)panDetected:(UIPanGestureRecognizer *)recognizer { CGPoint translation = [recognizer translationInView:self.view]; NSLog(@"\ncenter.y: %f\ntranslation.y: %f\n", recognizer.view.center.y, translation.y); if (recognizer

Android: Slide gesture and animation for switching between tabs

こ雲淡風輕ζ 提交于 2019-12-03 14:15:24
问题 I'm sure this has been answered somewhere, already, but I just can't find it: I have a TabHost with three tabs, each containing different views (not Activities). What I want is to make a swiping gesture from right to left and let the current view slide out to the left and the next view slide in from the right, thus changing the current tab. So, I want the switch between tabs to be triggered by a gesture (rather than only by clicking on the tab) and also want to show an animation when the

Android ViewFlipper + Gesture Detector

早过忘川 提交于 2019-12-03 14:02:21
问题 I am using gesture detector to catch "flings" and using a view flipper to change the screen when this happens. Some of my child views contain list views. The the gesture detector wont recognize a swipe if you swipe on the list view. But it will recognize it if it is onTop of TextView's or ImageView's. Is there a way to implement it so that it will recognize the swipes even if they are on top of another view that has a ClickListener? 回答1: Thank you for your answer. In order to get it working

Qt, Gestures. TapAndHold and Swipe are not recognized

本小妞迷上赌 提交于 2019-12-03 12:25:56
问题 I tried a "Image Gestures Example" from http://doc.qt.digia.com/4.6/gestures-imagegestures.html. In this Example you have only 3 Gesture: PanGesture, PinchGesture and SwipeGesture. But Qt provides 5 Gestures: TapGesture TapAndHoldGesture PanGesture PinchGesture SwipeGesture In order to recognize all 5 gestures we need to write into ImageWidget-Constructor: grabGesture(Qt::TapGesture); grabGesture(Qt::TapAndHoldGesture); grabGesture(Qt::PanGesture); grabGesture(Qt::PinchGesture); grabGesture

Swift 3 - Image view with Tap Gesture

十年热恋 提交于 2019-12-03 09:23:22
Im having issues with using a tap gesture that I have put on an image view. The image is currently stored in the Assets as 'ActionLiked' and I have set the image view to this image. It is then rendered into a table view which is dynamic based on JSON (so it repeats for each item I put into a JSON array). I added the tap gesture to print out 'TAPPED' each time I click on it however, it seems to not be working all the time - 7 items currently in the table, the tap gesture will work on 1 then not work on the next 2 then work on the 4th one and repeat that pattern ITEM 1 - WORK ITEM 2 - NO WORK
