Abstract: A head mounted device (HMD) has a transparent display. The HMD detects an event external to the HMD and determines a location of the event relative to the location of the HMD. The HMD generates augmented reality (AR) content identifying the event and a direction of the location of the event relative to the location of the HMD and displays the AR content in the transparent display.

Abstract: A head-mounted device (HMD) has a transparent display and an array of microphones. The HMD determines a task-based context of the HMD based on a task being performed by a user of the HMD, and determines an ambient-based context of the HMD based on audio data produced by the array of microphones. The HMD detects a first notification configured to be displayed in the transparent display of the HMD. The HMD intercepts the first notification in response to detecting the first notification and generates a second notification based on a priority level of the first notification, the task-based context, and the ambient-based context. The second notification includes a combination of an audio notification and a visual notification (AR content). The HMD replaces the first notification with the second notification and provides the second notification at the HMD.
