Tobii 4C with "Pro" License: variable descriptions for saved data

[Stefan]

Hi everybody,

I am using a Tobii 4C eyetracker with a Pro License. The Pro License means that I can read and save all data that the eyetracker collects. When saving the data, I get a CSV file with several columns and associated headers (one per “variable” that gets collected) … and then the values in the rows respectively.

Unfortunately I cannot find information about what the headers mean specifically.

For example the header “device_time_stamp” –> after browsing around for a bit I found that this corresponds to “Time stamp in microseconds according to the eyetrackers internal clock”.

However, there are many other headers that I cannot find descriptions about.

Is there a list or a reference guide that I can read for this information? It’d be great to have a mapping between each header and its description in a table format.

Thanks,

Stefan

Hi @sappelhoff, thanks for getting in touch. It looks like you are using the Tobii Pro SDK. Tobii provides a comprehensive reference guide for the Pro SDK detailing all the various class members.

You can view this @ http://developer.tobiipro.com/net/dotnet-sdk-reference-guide.html

I think therein you should find what you are looking for. Best Wishes.

Thanks Grant, it took me some time to compile all the information I needed … but the SDK documentation does indeed cover my question.
