Calibration Validation

The package contains functionality for validating calibrations by calculating various statistics for different stimuli points. Note: There is no functionality for actually presenting the stimuli points on screen.

tobii 4c linux support and SDK access

Sorry to bother you, i just saw tobii 4c available to purchase, and I am wondering if it is possible to make it work on linux?
In some places on the internet tobii company says i will need to buy some special upgrade pro key for their research license. But it's unclear if it's available for purchase nowdays.
