What:

We decided to use a microphone to detect the public speaker’s volume and visualize the volume information by NeoPixel which can be served as a reminder for the speaker to use proper volume when they give speeches.

Where:

Classroom (Pod)/ Public Space (As Installation)

When:

Giving Presentation/ Rehearsal/ Practicing/ Party

How:

The NeoPixel will give speaker real-time feedback on their volume and voice visualization, and after the speech, the speaker can check their volume history on their phone which is able to help them improve for next time.

At the same time we were thinking about whether we could hang the whole installation, so that it would give the speaker real time feedback and it would hang on the wall as a work of art.

Prototype:

We use Rhino to make the 3D model.
And then we put the model into the real background to see the effect.

Bill List:

NeoPixel

Electret Microphone Amplifier – MAX4466 with Adjustable Gain

Mini Illuminated Momentary Pushbutton – Blue Power Symbol

Mini Illuminated Momentary Pushbutton - Blue Power Symbol

TBD: Adafruit Accessories Mini 8×8 white LED Matrix(maybe larger)

Frosted acrylic light diffusion tube

Interaction:

We’ve thought about a lot of ways to interact, and we’re going to do a follow-up experiment this week when we get the material together.


1.Lights flicker like flames to show volume


2.The light changes color with the volume of the sound (for example: the volume is small blue, and the light becomes red as the volume increases)


3.Simulate the curve of sound wave to change the position of light

Amplitude waves. Music sound voice wave. Dynamic equalizer
