Ordinarily AR eyewear devices neither use a game controller or clicker nor positionally tracked hand controllers. Instead, you use your hands. Hand gesture recognition is another challenging AI problem for computer vision and image processing.

In conjunction with tracking, where the user is looking (gaze), gestures are used to trigger events such as select, grab, and move. Assuming the device does not support eye tracking (moving your eyes without moving your head), the gaze reticle is normally at the center of your gaze. You must move your head to point to the object of interest that you want to interact with:

More advanced interactions could be enabled with true hand tracking, where the user's gaze is not necessarily used to identify the object to interact; however, you can reach out and touch the virtual objects and use your fingers to push, grab, or move elements in the scene. Voice command input is being increasingly used in conjunction with true hand tracking, instead of hand gestures.
