Abstract: An augmented reality device manages display of an interactive icon in a manner that enables selection by a simple and intuitive gesture. The interactive icon may initially be displayed at a predefined target position outside the fovea where it is visible in the near peripheral vision without being distracting to the user. The augmented reality device may control the icon to behave like a stationary object with respect to changes in orientation until selection or repositioning criteria are met. Upon detection repositioning criteria, the augmented reality device may reposition the icon to the target position. Selection of the icon may control functions such as alerting the user to an available notification, opening or closing a menu, or performing other actions associated with operation of the augmented reality device.
