Eye Tracking Data

Hi,

I'm currently working on a project and hoping to retrieve data from eye gaze. I'm looking to utilize eye gaze for controlling an interface, requiring the data for tasks such as selection or button pressing. If anyone has alternative methods to achieve this, feel free to recommend; it would be greatly appreciated. I haven't been able to find a way to retrieve this data. Although there's OVRManager.isHmdPresent, there doesn't seem to be OVRManager.eyeTrackingEnabled.
