Hi @nekromantcer, if you check out the samples included with the Core SDK available @ https://github.com/Tobii/CoreSDK
herein are shown a number of ways to display the gaze data alongside time stamp information.
It should be simple enough to output the console values to an array as you go and thereafter trim the entries to 0.5 seconds apart (as close as possible)
Please however bear in mind that the long term storage of gaze data is prohibited within the Tobii Core SDK licence and that
if you wish to retain gaze data for analysis or research, this necessitates the purchase of a special licence to do do.
If you could kindly expand on what you are trying to achieve, we may be able to figure out a workaround based on your needs. Many thanks.
