My grandmother got her iPad somehow in this state where it seems to be in language setup, but taps dont work as expected, rather they activate unusual boxes on the screen:
How can I fix this? Holding down the power and home button for 10 seconds restarted the iPad but the same screen was there. No interaction seems to be doing anything to advance the setup, the boxes that pop up seem to be interfering. The box in the image appears after tapping.

I figured out the answer. This state is called Voiceover, its an accessibility feature for the visially impaired,
However when used unintentionally by someone who doesnt know the special controls of the Voiceover feature, it can seem that the device simply is not responding to touch.
One simply has to tap buttons to select them then doubletap to click them, navigate to the Voiceover memu under accessibility and turn it off. Alternatively clicking the home-button 3 times in rapid succession enables/disables this feature.
