Rails 3 POS Software for touch interface with jQuery

Hi guys,

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:

I have refactored a lot of the javascript to make it run faster (taking
into
account guidelines from here:
http://blogs.msdn.com/b/ie/archive/2006/08/28/728654.aspx)

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?

thanks,

Lee

anyone?

Did you try Google Chrome browser?

Have you had a look at HTML5 specs for Safari? Offline storage might
help you speed things up a little if you are constantly going back and
forth to the server for repeated data.

Here’s a link to an Apple demo:

Actually chrome is a fraction faster than firefox, which helps a lot.
thanks.
It still needs to be faster however, so I will have to keep tweaking it
as
such.

I think we are limited by the speed of the JS engine? In which case
there is
nothing we can do there.

I already use a lot of offline storage, and the interface is completely
javascript based (all data is preloaded, and screens are switched via
showing/hiding divs).

I may have a problem that there is just too much JS in the interface?
Could
that ever be a problem?

thanks for the reply
