Hi Stuff Team ,
I Have a Medical Project to Track the eye and Detect the Nystagmus ( un Controllable movement in the eye ) with respect to the time , I Work with Python and i know that i can get the timestamp with Headset.waitAndFetchNextEyeTrackingData( ) and Can get the Values of x,y,z through getGazeVector( ) ( if there is something False mention me please as the measurement should be accurate )
I need to Know :
1- How Can i Get the Origin of Each eye as it is the reference for me
2- X,Y are the displacement/distance that the eye move from which reference
i mean when x = - .002 and y = 0.147 ( i Get them from your sheets )
x , y are referenced to what which they moved from it !?!? to the origin i
asked about befor ?
and they are of course in mm right ??
3- i need to calculate the Horizontal displacement in Degree ( Angle ) and the Vertical one in degree also is there any function can help me ??
3- Z is the direction of the Ray right ??
4- is there any function can help me to calculate the Torsion in the basic not pro
