What is the concept behind OptiTune?

Restoring the connection of an individual who has headphones on with other individuals, through displaying real time visualizations of what the user is listening to.

What is the form?

A 3 inch cylinder that lights up according to the beat of your music.

How does it work?

You can either plug in your headset and have the lights turn on according to your playlist, or take the headset out and have OptiTune visualize the sounds surrounding you.

What materials does it use?

  1. Arduino micro
  2. 3.5 mm audio jack (x2)
  3. 3.5 mm audio cable
  4. 100k resistor (x3)
  5. Porto board
  6. PCB mount pins
  7. Portable USB charger


What needs to be done ahead of time?

  • Create prototype
    • Set up the board with NeoPixel and microphone
    • Sewing the prototype into a badge
    • Constructing circuit and decorate the badge
  • Charge battery pack

Do you need extra batteries?

  • We have decided to use old phone batteries

What goes into your repair kit?

  • Fabric, thread and needle, battery charger

During Process:

First of all, we will document our user experience on using the the optune. And also select a group of testers to try it. We will document the process by vedio and writing notes.

Secondly, we will carry on our stuff and test it in a daily life. We will take notes regularly and also take selfies at different locations. We will be observing other people’s reactions to us playing the Optune, and we will collect  quantitative data like how many times does people inquiry our product.

Crunching the data

How will you structure a debriefing conversation?

  • Meet for a debriefing conversation, and take notes

What will you do with the data and media once you find it?

  • Look for improvements for future iterations
  • What was liked about the device?
  • What was not like about the device?
  • Was the device comfortable?

Where did you place your OptiTune?

We mostly put it next to our laptops when we were working on our projects at school. It was a fun and playful object that made stressful times entertaining.

What did you like about OptiTune?

Looking at the beautiful lights! Especially in the dark when the lights are off, or when you are taking a walk outside. It really is beautiful and exciting to see the music you are listening to.

What did you dislike about OptiTune?

The case, and the wires.

For future iterations we will have a case that can not only keep the device safe and waterproof but can easily be attached to anything.

How was the experience of the observers of your OptiTune?

We were on campus most of the time. So many of the people who passed us by were students. The fun part was when we were visiting the undergraduate buildings and the students would ask us if we had bought them from the OCAD store. Ofcourse, with pride we told them that we had made them as part of our project.optituneposter optizine_p_page_1 optizine_p_page_3optizine_p_page_4optizine_p_page_5 optizine_p_page_6_mg_3127_mg_3086
