Unity C# TouchScript - Overlapped collider detection issue

I'm working on a 2D non-game application. I used TouchScript to have all the multitouch gesture but I have an issue.
In the application, i have the ability to open a lot of popup that are draggable, pinch resizable and we can rotate them.
These popup are made with UIPanel. I add a collider2D on them
The issue is that when 2 popup are overlapping, if i want to move the one on top, i will randomly hit the one on the back or the top one.
It i like the touch goes through the first collider to hit the one behind...

First answering to the comment on your question suggesting to use the UI event system:
If you just use unity's UI events, you won't get advanced gestures such as swipe, pinch, etc and will have to code it yourself.
If you need these gestures, Touchscript is working fine and is a good choice.
Now to your question: I had the same problem and solved it by putting the script "UILayer" on the camera, instead of "CameraLayer2D"

Best way to draw moving sphere in a smooth way in C#

Hello: I am trying to create an app which will display a moving sphere. App will vary speed and direction. I've tried Adobe Flash but cannot get it smooth. Smoothness is essential in this case. So I am trying C#.
Initially, I can see that this can be implemented by:
1) Creating a PictureBox of a sphere, and using a Timer, change its coordinates. or
2) Using the this.paint function to draw a filled circle, and somehow, with a timer, erasing and redrawing it.
Can someone recommend the best path to take? I'll have a main menu where the user will chose speed/direction/how many etc... and then simply show the "game window" with the moving spheres. Any guidance would be much appreciated.
This is to be displayed on a PC only.
Thanks

I just answered a similar question here.
NOTE: Depending on your needs, it is possible to achieve smooth animations under winforms (under certain conditions) though you are responsible for everything. wpf provides an animation framework but wpf is perhaps a milestone harder.
It probably does not matter should you pursue winforms first or WPF. You arguably could learn the basics under winforms then move over to wpf. wpf may require you to learn quite a bit before you can do anything.
Summary
Essentially what this does is to create an offscreen bitmap that we will draw into first. It is the same size as the UserControl. The control's OnPaint calls DrawOffscreen passing in the Graphics that is attached to the offscreen bitmap. Here we loop around just rendering the tiles/sky that are visible and ignoring others so as to improve performance.
Once it's all done we zap the entire offscreen bitmap to the display in one operation. This serves to eliminate:
Flicker
Tearing effects (typically associated with lateral movement)
There is a Timer that is scheduled to update the positions of all the tiles based on the time since the last update. This allows for a more realistic movement and avoids speed-ups and slow-downs under load. Tiles are moved in the OnUpdate method.
If you note in the code for Timer1OnTick I call Invalidate(Bounds); after animating everything. This does not cause an immediate paint rather Windows will queue a paint operation to be done at a later time. Consecutive pending operations will be fused into one. This means that we can be animating positions more frequently than painting during heavy load. Animation mechanic is independent of paint. That's a good thing, you don't want to be waiting for paints to occur. xna does a similar thing
Please refer to my full SO answer complete with sample code

Here are a few hints to get you going:
First you will need to come to a decision about which platform to target: WPF or Winforms.
Then you should know what to move across what; a nice Bitmap or just a circle across an empty background or a Bitmap or a Form with controls on it.
In Winforms both your approaches will work, esp. if you set a circular region see here for an example of that. (The part in the fun comment!)
And yes, a Timer is the way to animate the sphere. Btw, a Panel or even a Label can display an Bitmap just as well as a PictureBox.
For smooth movements make sure to set the Form.Doublebuffered=true, if you move across a Form. If you move across any other control (except a PictureBox or a Label) you will need to subclass it to get access to the DoubleBuffered property!
It is often also a good idea to keep the Location of a moving item in a variable as a PointF and use floats for its speed because this way you can fine grain the speed and Location changes and also the Timer Intervals!

How do I do a "mouse click" with kinect?

I'm in the midst of developing a kinect application.
Basically, what I have now is a simple WPF form with 3 buttons, a rightHand image and a leftHand image is tracked and is working.
I have 2 problems though.
1st Problem: Unable to move "hand" pointer to the extreme right and left.
I know this has something to do with bounding box and i'm still looking for a solution online.
2nd Problem: How do I initiate a "click" without making use of Kinect Region and the Kinect Tile Buttons? I'm looking for something similar to the video shown below

If this is what you are looking for ?
X-box common gestures - Open the system menu
I think you have to use timer to check if the current positon is where you want it to be and start a counter for few secs.
Maybe this can help:
Hovering button

WPF - touch gestures - suppressed mouse click if scrolling

I have multiple videos in ScrollViewer and when I click on one of these videos It plays and I got movie on fullscreen and where I moved with scroll bar It's moving with videos. This is okay. I have implemented this by adding mouse click to media element and now I am testing this on touch screen and it's working.
But I want to differentiate between click on video and moving in that area. That user don't want to "select" video but he is just moving with area but not in scroll bar but in area with videos. For better understanding I added image:
To have WPF make difference between click and move (to have both but still calling just one). What is the best way to do this? Thanks

It is very hard to handle touch events on your own, especially when you have to handle nested controls.
I think the easiest way to solve this, is for you to use the Microsoft Surface Touch Pack
Replace your ScrollView with a SurfaceScrollView and place a transparent SurfaceButton above your MediaElements and react on the Click-event (or handle it via the a command).
This way, Microsoft does the tricky panning (scrolling) or tapping (clicking) for you. And as a nice side effect, you get things like bouncing and interia of the ScrollViewer for free.

Scroll the scrollviewer with mouse at the end of the screen like the Windows Start menu [duplicate]

In the Windows 8 Consumer Preview, moving the mouse towards the left or right edge in the start screen causes the content to scroll.
The standard controls (and currently released preview apps) does not seem to support this.
Is there a way to make this work?

I asked this question at TechEd North America this year, after one of the sessions given by Paul Gusmorino, a lead program manager for the UI platform.
His answer was that no, apps can't do push-against-the-edge-to-scroll. WinJS and WinRT/XAML apps don't even get the events you would need to implement it yourself. Apps get events at the level of the mouse pointer, and once the mouse pointer hits the edge of the screen, it can't move any farther and you don't get any more events. (Well, it might wiggle up and down a little bit, but not if it hit a corner. At any rate, it's not good enough to scroll the way the Start screen does.)
He mentioned that, if you were writing a C++/DirectX app, you would be able to get the raw mouse input you needed to do this yourself -- you can get low-level "device moved by DX,DY" rather than the high-level "pointer moved to X,Y". I'm guessing this is how the Start screen does it, though I didn't think to ask.
But no, it's not built-in, it's not something you can implement yourself (unless you write your app in low-level C++/DirectX), and it sounds like they have no plans to add it before Windows 8 ships.
Personally, I think it's pretty short-sighted of them to have apps feel cripped compared to the Start screen, but evidently they're not concerned about little things like usability. </rant>

You can do the following to get information on mouse moving beyond the screen and use the delta information to scroll your content.
using Windows.Devices.Input;
var mouse = MouseDevice.GetForCurrentView();
mouse.MouseMoved += mouse_MouseMoved;
private void mouse_MouseMoved(MouseDevice sender, MouseEventArgs args)
{
tb.Text = args.MouseDelta.X.ToString();
}
