So I am working on an application which requires me to track eyes in 3D world and I am using Tobii EyeX for the same. But the problem is that during the head movement sometime eye tracker is not able to detect eyes and I need it almost in every frame at 25 fps. I am trying to use a mean filter with history of last 10 values (assuming constant velocity of head) to predict the missed prediction of eye ball, but it’s not smooth . Can someone suggest a more robust filter to predict the values missed by the eye Tracker?05/12/2016 at 21:31 #6007Grant [Tobii]Keymaster
Hi @optimud, It seems like you are attempting to store data from the Eye Tracker for long term storage which is quite explicitly forbidden in the licence agreement for the EyeX.
That being said, if you search online for IV-T Filter (which Tobii Pro products make use of) then that should point you in the right direction.06/12/2016 at 06:42 #6010MayankParticipant
Thanks for your reply. I am not storing the data for long term, I am using it for instantaneous actions and that’s why I needed an online filter.06/12/2016 at 12:28 #6011Grant [Tobii]Keymaster
All right, thanks for the clarification! I think the methodology for the IV-T filter should still be of use.
