Labvanced.com released a big eye tracking update
N ow you can have a static sampling rate of 30 Hz and also have no impact of the eye tracker to the main experiment performance/ accuracy, which was a major drawback in the previous version. In fact, we are now optimistic to include (maybe later this year) even a 60 Hz sampling rate optio n for setups with 60 Hz webcams, which become more and more common these days! How can you test / activate this?: You go to study settings and on the eye tracking section you will see a new option called "calculation mode", simply put this to "high sampling": You can also see the detailed comparisons of the different calculation options (see screenshot): Without wanting to be too technical here, the main achievement is that everything works now in parallel threads, hence is not blocking the experiment execution / precision (which was a problem before) and thereby everything is much faster. A good analogy is that we go from a single congested traffic lane to a multi-lane highway, so...
