Techniques are disclosed for facilitating action by a user on a simulated object in an augmented reality environment. In some embodiments, a method includes, detecting a gesture of the user in a real environment via a sensor of the device; wherein, the gesture includes, movement of eye ball or eye focal point of one or more eyes of the user. The gesture can be detected by tracking: a movement of one or more eyes of the user, a non-movement of one or more eyes of the user, a location of a focal point of one or more eyes of the user, and/or a movement of an eye lid of one or more eyes of the user. The gesture can be captured to implement the action on the simulated object in the augmented reality environment.
