1. A method to facilitate action by a user via a device on a simulated object in an augmented reality environment, the method comprising: detecting a gesture of the user in a real environment via a sensor of the device; wherein, the gesture includes, one or more of: movement of one or more eyes of the user, and movement of eye focal point of the one or more eyes of the user; capturing the gesture to implement the action on the simulated object in the augmented reality environment; wherein, the gesture is detected based on a given speed or velocity of the movement of the one or more eyes while the one or more eyes is in motion relative to the user; wherein, the action to be performed on the simulated object is based on the gesture that is detected; wherein, the gesture includes locating the eye focal point of the one or more eyes of the user to target the simulated object that is in the eye focal point; wherein, the eye focal point is determined from the given speed or velocity.
