Way to find Visual angle ?
Hi Team,
I want to measure eye angle using the Fove VR. Is there a way already to do so ? If not, do you have any suggestions ?

Hey Snehal,
Assuming you know the two vectors v1 and v2 pointing towards their respective target, the dot product between v1 and v2 will yield v1・v2 = v1 v2 cos(theta), where v is the norm of the vector v.
If you normalize v1 and v2 such that v1 = 1 and v2 = 1, theta will be such that theta = acos(v1・v2).
Please let me know if this helps.
Cheers,
Kevin
