In software, I don't think there is any you can do from a webpage html. Unless the browser has a bug that makes it lock up, it's not possible to block the inputs, after all there has to be a way to go back to the main menu?

If you have a way to run a script on the Kobo itself (maybe via my WebPortal mod, using a custom CGI script?), you can disable the touchscreen like such:

Code:

# ls /sys/bus/i2c/drivers/zforce-ir-touch/
0-0050  bind    uevent  unbind
# echo 0-0050 > /sys/bus/i2c/drivers/zforce-ir-touch/unbind

That tells the touchscreen driver to unbind ("unplug") the touchscreen in software so it no longer works. To recover touchscreen functionality, you have to reboot.

You could also do this in hardware. An 8" screen protector that covers the entire bezel might prevent all touches. But if you're using this on a boat, I'm not sure how well that works in wind and weather and whether it would obstruct screen visibility. Or a waterproof bag for the entire device that doesn't come in contact with the screen. You could also use something soft/opaque around the screen borders to blind the IR touch entire.
