Virtual Button Inconsistent

I have a problem with the virtual button.

sometimes its detected the touch, sometimes its not.

If I read the trackable from image on the monitor it won't activate the button touch even if all my fingers covered the virtual button.

but if I read the trackable from printed image it can activate the button touch

 

but after I tried again on another device the button won't detect touch even if I use the printed Image.

 

I wonder what could be the problem? color? camera quality? or anything else?

Hi, the detection of Virtual Buttons is very sensitive to the design of them and to the surrounding image target;

Thanks.

 

so the design of the virtual button is also affecting the quality of detection? I thought that just by covering the whole virtual button area it would be detected as a touch.

should the button be contrast with the background?

I'm sorry but, how is actually the right code to read the button?
should I use the Virtual button from VirtualButtonResult or I get the virtual button directly from the Image Target?

I found this tutorial is  ambiguous 

Hi fugougo,

Alessandro is quite right here about the design aspects of VBs.

One suggestion that some other developers are using is to have a button displayed as an augmentation so that the user can touch it on the screen.
