H4AR is a device for assisting hard-of-hearing people in their everyday lives, by visually alerting them about the direction of important sources of sound. Specifically, we will focus on alerting them to human conversation or voices around them.

The device is a wearable pair of glasses, equipped with an array of microphones and simple augmented reality in the form of a small heads up display. This microphone array will identify human speech, and determine the direction of the sound relative to the individual. This information will then be displayed as a visual cue in the form of an arrow on the heads up display, pointing towards the direction of the source of sound, This will greatly increase the individual’s peripheral awareness, allowing them to identify and turn towards people talking to them.
