Can't connect EYEX using URL

[Vijay Rajanna]

Hi,
I am using EYEX with Gaze SDK ( C, 32 bit).
To connect to the tracker I pass the tracker URL as per the documentation
tobii-ttp://EYEX2-11111111 [tracker id not shown].

However, I get can error

Image URL: http://bit.ly/1NNH1mt

However, with “–auto” option the system works just fine.
In case of –auto the system reads an URL tet-tcp://127.0.0.1

Please let me know how this issue can be resolved.

Hi,
Could someone respond to this query?

[Vijay Rajanna]

Could someone from Tobii answer this question at the earliest?
I’m using the URL format as specified in Tobii documentation for Gaze SDK C API.
Thanks.

Hi,

Is there any update on this issue from tobii?

[Richard Ray Wellman]

I would suggest contacting them directly via email. It doesn’t seem that these forums are monitored all that frequently.

Hi Vijay,

Sorry for the delayed response. I try to check the forums weekly, but sometimes I’m out traveling, and sometimes I need to get additional info from colleagues which might take a while.

The EyeX Controller is a TCP/IP eye tracker, and can only be used with the tet-tcp scheme.

As it says in the Gaze SDK Developer’s Guide – General Concepts, in the section about Eye tracker URLs:

The URL for a TCP/IP eye tracker uses the tet-tcp scheme instead of tobii-ttp, and the host part (i.e. the part that follows the double slashes) can be either an IP address or a hostname that the operating system can resolve into an IP address using for example a DNS lookup.
