Review on Enhanced Touchscreen Experience with GreenTouch Points Infrared Overlay Screen 32 - GT-IR-F32.0-1 by Mike Abu

I used it to build a wall display. I made a groove to hide it in the frame just in front of the plexiglass to protect the real monitor screen. It worked really well because plexiglass is much closer to the point where it sees your finger. So I don't have as big a problem with it as other reviewers. In the middle of 90% of the screen everything works so well that you can navigate through the windows normally. The only bad thing is when you try to touch corners or when you want to right click. For example, I can't press X in a full-screen web browser. I have to drag the window down and then press X when it's closer to the center of the display. If you want to right-click, you need to press and then hold again. The sensor almost always thinks your finger is moving and therefore doesn't work properly. You can get it eventually, but it's not always easy. I'm still giving 4 stars because I don't expect this infrared touch sensor to be anywhere near as good as what most people are used to. It's just not possible, but even then it's perfectly applicable.
