H4AR

1. Performed current/power calculations for determining the battery
2. Finalized BOM with team together
3. Worked and codified design and slides with rest of team
4. Investigated osxAcousticSL library interfaces

1. Did calculations to make sure that sampling frequency was sufficient, and that for reasonable distances the angular resolution will also be good
2. Did order-of-magnitude calculations to check that our response time will be < 500 ms (can’t say with certainty yet, but seems to be in the ballpark, under 500 ms)
3. Looked at possible time-domain implementations of gcc-phat
4. Worked on design review points, and slides with the team
5. Finalized our BOM with the team

The slides for the proposal presentation are linked here.

Sound2Sight 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.
