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.

System for selective presentation of notifications

Operation of a head-mounted wearable device is responsive to whether a state of the device is being worn (donned) or not worn (doffed) on the head. The device may operate in a first mode while donned and a second mode while doffed. A capacitive sensor device having an electrode positioned in a bridge of the device provides output data. The output data is processed to determine a baseline value. Later, acquired output data is compared to the baseline value to determine don/doff data indicative of whether the device is donned or doffed. Data from other sensors, may also be used in conjunction with the output data to improve accuracy of the don/doff data. For example, if the output data is above the baseline value and accelerometer data is indicative of motion greater than a motion threshold, the don/doff data may be designated as donned.
