Is it possible to simulate touch without root?

Is there any way to simulate a touch (anywhere) on the screen without root? If not, is there any other way I can perform a *cardboard* 'select' action without magnet support, or opening up my *cardboard* every time? ### Background I am trying to get *cardboard* apps to work to work with a 5.1 phone which doesn't support the magnet 'button'. Most apps seem to use the button to select or advance, so without it working, it is difficult to use. I have found that a touch anywhere on the screen also works as a select, so what I'm doing at the moment is opening the back, touching the screen and then closing it up again, but obviously that quickly gets tedious. What I have tried: * Using my ipega 9017 gamepad (in Gamepad, Keyboard and iCade modes) no mode maps any key to anything which performs a select action in *cardboard* (though some modes map the B button to back, which works to exit a *cardboard* app at least). * I have tried Tincore Keymapper , but that requires root in order to simulate touch, and I cannot root my device. * Looking on here, custom keymapping for games? , Can I use USB gamepad without any setup? and Mouse to touch? looked most promising, but none of them answer this question.
