Hello .. Am new to all this am helping out my son for his school project , We connected Arduino UNO to processing 1.5.1 standard , We up loaded sketch called touchless 3D tracker interface , However we keep receiving the error

In simple way how can we fix it to get it to work and interact with hand motion .. Thanks for all your help

That's not an error (I think) but a warning, ie. something that doesn't stop your code from working.
I got this message a few times too.

Incorrect .. Message correspond to serial interface mismatch , The sketch file Loaded to processing serial value set = 0 by default to =COM1 on Laptop , to set it to COM2 you must change the value to 1 and so on .However upon connecting and loading the Arduino UNO the Laptop detect it as COM3 .. So there is a mismatch between serial interface and the physical connection upon cable to cardboard .

But if you change the Processing file value nothing work and am still trying to force the PC to set USB as com1 to match sketch ...Any ideas

Regarding the display message, PhiLho is correct, it is quite normal for people to have more than one display (bear in mind processing was developed on the desktop ), and the message about display is often spurious. But it looks like you are seeing another error, a complete error report might be helpful....

Only other error message that pop on the screen below the above is

WARNING: RXTX Version mismatch

Jar version = RXTX-2.2pre1

native lib Version = RXTX-2.2pre2

And that is the project we doing

" Incorrect .. Message correspond to serial interface mismatch"
That's not the message you shown in your first post...
The other message is also very common, a quick search in the forum will show lot of related threads...
