connecting to SMI iViewX running a RED tracker

[pkhoosh]

Hi,

I followed the hardware reference for connecting to the SMI eye tracker using iViewX, but there are no changes to the XY pupil position that I'm printing in Vizard. I'm assuming the values it prints should change a little because my is moving. It just prints [0.0, 1.0, 0.0] for the normalized data (and [0 1023 0] for the raw pixel value). A related question: Why is the output a 3 element vector (and not just two for the XY?)?

Let me describe our setup. We have the SMI laptop that runs iView X (address= 192.168.10.1, port=4444).

We have another computer running Vizard (address=192.168.10.7, port=5555) and the SMI Experiment Center (to which we need to connect for the study; we configure this with remote interface 2 in iViewX).

According to the Vizard help instructions, I setup the hardware section of iViewX to communicate to remote interface 1 via Ethernet. The iViewX network config is set to listen to 192.168.10.1 (port 4444), which is the laptop running iViewX, and send UDP packets to 192.168.10.7, which is the Vizard computer. According to the Vizard reference, I set the port value for both listening and sending as 4444 (the iView laptop). (What's the logic behind that?)

Am I missing something? The tracker is a RED4 using FireWire.
