Virtual keyboard

June 7, 2011 - 7:21pm #1

Hi guys,

I am investigating if it is possible to use QCAR to create this type of application: keyboard recognition, i.e when pointing my phone camera to a laptop/PC keyboard, it can recognize the pressed buttons and display the recognized char. sequence on the phone's screen.

QCAR can recognize the physical keyboard just as an image target but it seems it fails to recognize the physical buttons as virtual buttons.

Is this thing possible with QCAR another way or ...?

Give me a clue pls.

Thank you!

This isn't an ideal use case, a keyboard doesn't make a particularly feature-rich target, and virtual buttons depend on a dense area of features to detect occlusion. Also, you would most likely occlude lots of other keys while reaching in to press a particular one, it could be tricky to figure out which key the user is actually pressing.
