For more clarification, i think i should explain more details about what i want to do.
I have some points in 3-d coordinate, and i want to project that points to eye positions using Tobii eye tracker.
I just want to calculate projected points coordinate.I think it’s not an analytical use.
But for that, i need to get ‘user key input’ in real time without delay in function ‘HandleEvent’
and i need to get eye positions and gaze point data simultaneously.
