Capture a game performance as video in labview

[anushaas]

Hi,

I need to acquire certain physiological parameters from a person attempting the following test in the net

I have a vi to acquire the signals which is attached alongwith.

Now I need to continuously monitor the test screen as well while the person is attempting it so that I can relate the test result (ie. whether attempted question is right or wrong) with the physiological parameter variation.

Can anyone tell me how to do this in labview?

Using the Vision Acquisition Software Toolkit (which, I believe, is an "extra-cost" item in LabVIEW, unless you have a "license for everything"), you could, in principle, use a WebCam to take a video of the video monitor.  I don't have experience in doing this, so I don't know what "gotcha's" there are in synchronizing (or not) the two imaging systems.

I notice that you are doing everything with Express VIs, which "hide all the details" from you, and give you much less control of timing and synchronization -- there may be trouble down the road.

I found the following vi for screen capture but this vi captures a predefined area based on mouse position.

How can I change it so that the full screen in which mouse moves is acquired all the time?Also where are all the png images saved after execution of vi?
