Hi ,


I have a query with regard to Multimonitor touch screen support in
Windows XP Embedded.

We want to control multiple video applications simultaneously in
mutiple touch screens and we are using Windows XP Embedded . In
normal case the display will be coming from the host cpu and through
Analog/DVI interface reaches the monitors. But in our custom
architecture we are having an intermediate touch panel card to which
the control commands of touch reaches and through which the DVI output
goes to the screen.The display comes to this intermediate touch
panel card through the PCI Express bus from there through DVI
interface to Touch panel .

Operating system and driver will be running in the
host.

Can anyone guide me on how to control multiple video applications
simultaneously in mutiple touch screens or whether this kind of
support is there in XP Embedded ?


Thanks in advance,
Rupesh
 
It can be done. The trick is setting up the touch screens with the right
monitor. As I recall, it comes down to install the touch screen driver by
hand to get the right order. Are you using Serial or USB touch screen?

We are using Serial touch screens, i'll repeat a particular scenario,
here we have a single processor using which we have to run two
different applications simulateously in two different touch screens.Do
you think that whether it is feasible with the current architecture ?
Please note that we are not using any graphics card we will be
developing our own custom display driver for both touch screens.
Also can you please elaborate upon your previous explanation on
setting up the touch screen and installing the driver.

Thanks in advance,
Rupesh

There is only one mouse cursor in a system so standard touch screen
systems that emulate a mouse would be an issue if both screens were
touched simultaneously.

It would be theoretically possible to do what you wand but you would
need to develop the touch screen firmware, driver and interface to the
user software. I imagine this would be quite a complicated project.

Hi Mike,
Mouse events are generic events right ? Can we have user defined
events which supports multiple simultaneous user inputs on two
monitors connected to a single host ?

Hi Sean Liming,

Can we interface the driver ( which supports simultaneous multiple
applications ) eventhough we have a custom architecture ?

Thanks in advance,
