The app, detects QR code in real time. The app will continue following the QR code as long it is readable. In addition, the app will detect the pixel colour (RGB) of the touch. In practice, once one touches any location of the screen the app, will collect the location of the touch gesture, and then updates the colour of the text on the screen to match the RGB level of the chosen pixel. This app has been primary designed as a requirement to fulfill academic research. But, anyone who feels interested is welcomed to locate the source code on my Github profile and use it for their own application under MIT licence.
