We have developed POS software, in Rails 3.0 that is to run on tablet and touch screen PC’s.
The main menu interface is using jQuery, and all of the buttons on the screen are simply divs that respond to onclick events.
The interface is not as fast as a native application would be as we are restricted to response time by the browser itself (we are currently using firefox).
We have overcome the delay on the ipad using the script and guidelines here: http://cubiq.org/remove-onclick-delay-on-webkit-for-iphone
Is there anything else we can do to make the interface a bit more snappy?
I am looking into using Palemoon (http://www.palemoon.org/) also, but I still don’t think that we will match up to the response time of native apps.
Anyone got any advice?
