Need to capture user signature

CI or not won't make much of a difference.

You need a broswer plugin or client-side script that can capture touch input, translate it to an image and upload it to the web server. PHP can't really help you until you have data arriving at the server.

Running on a tablet PC is no problem - just adjust for screen resolution. However - ensuring that the user is not asked to sign on a system that DOES NOT take touch input will be harder.

From a PHP standpoint, this is no different to asking users to provide an avatar - PHP doesn't care how the image care into being.

On the PHP-side, though, you're going to need some pretty impressive security to guard user signatures, and a whole heap of trust from your users to be given that kind of information.

Try looking at touch-specific client-side scripts - javascript or smart phone api would be where I would start.
