<div>I have a new project, that has me stumped in a couple of areas.</div><div>The project is to use a couple of repurposed Raspberry Pi 3's in kiosk mode for lobby touchscreen event directories.</div><div>The most pressing problem is to do an auto return to the first page ( I'm doing this all in HTML4) when the guest walks away and leaves the kiosk in an unknown state. Nothing so far in Google makes sense to do an idle timer.</div><div>The other issue is cursor to touch alignment (index calibration). Which diverges further, going away from center screen.</div><div>The screens are ACER T272HL and made in 2012. No calibration software to be found. Still looking for generic software.</div><div>Only 7 action buttons, on the bottom of the screen, no keyboard, no internet, just 7 screens.</div><div> </div><div> </div>
