Abstract: A head-mounted wearable device (HMWD) incorporates a visual indicator device (VID) that provides a visual cue to a wearer about activity of the HMWD. The VID may be positioned in a frame of the HMWD to be within an upper portion of a wearer's field of view during wear. The VID may provide a diffuse illumination that is visible to the wearer but does not obtrusively illuminate the face of the wearer, resulting in the visual indicator being unobtrusive to bystanders. Activation, intensity, color, blink rate, or other characteristics of the visual indicator may be used to provide the wearer with information. For example, the VID may illuminate with a solid color while a microphone on the HMWD is active, or blink while the microphone is muted. Input from an ambient light sensor may be used to adjust the operation of the VID during operation.

Abstract: A device, such as a head-mounted wearable device (HMWD), provides audible notifications to a user with a voice user interface (VUI). A filtered subset of notifications addressed to the user, such as notifications from contacts associated with specified applications, are processed by a text to speech system that generates audio output for presentation to the user. The audio output may be presented using the HMWD. For example, the audio output generated from a text message received from a contact may be played on the device. The user may provide an input to play the notification again, initiate a reply, or take another action. The input may comprise a gesture on a touch sensor, activation of a button, verbal input acquired by a microphone, and so forth.
