A few questions about the Pico Eye Pro 3 that we have. All are important for us to go forward with the headset so we need to have each one answered as detailed as possible.
1) The functions appear to only run in a ‘poll’ method - is there some sort of event or callback method we can use instead to get the data as fast as possible without running in a separate polling thread?
2) What is the sampling frequency of the eye tracking hardware? With our polling thread we are reading at 72fps (once every 13ms) but we see that data is often repeated.
3) We are not getting separate EyeGazeLeft, EyeGazeRight values etc - these are always zero. Is there a method to get the separate eye gaze values? Our concern is that someone who is blind in one eye will not be able to use this.
4) Calibration: do we need to recalibrate for each new person who is using the headset? If so, is the project that provides the eye calibration app available for us to embed?
