Hi @abirami,
The technique used to access to the coordinate point was explained further up in this thread.. did this not explain adequately what you were trying to achieve?
Perhaps you were no longer referring to accessing the data within Unity and rather within a standard EyeX SDK program?
The means to do this is well explained within the user manual. If you could be more explicit with the issues that you are having, I will try to point you in the right direction.
