Expressive Wearable – Dancing Belt

Dancing Belt

My expressive wearable is a belt that detects the wearer’s dancing. Reinforcing the benefits of dancing for the human body, the belt measures continuous movements to determine that the wearer is dancing, and rewards them with positive sounds and neopixel lights. When the wearer is still, it encourages them to move with pressing sounds and lights.


Parts List

  • Circuit Playground Express
  • Linen pillowcase (any thick, white fabric would do)
  • Conductive thread
  • Non-conductive thread
  • 2 pieces of conductive fabric
  • Long piece of fabric (I used a pre-existing fabric belt)

Concept & Objective

Happiness + Motion = Dancing. My concept for this wearable was inspired by the experience of dancing with my friends pre-COVID. When we’re out together (as an introvert and someone who’s quite shy), I sometimes forget to just enjoy the moment, have fun, and dance with my friends. This led me to imagining a wearable that would encourage me to, essentially, be happy and have fun!

Therefore, my final concept is a belt that detects the wearer’s ‘dancing’ and encourages continous movement when they are still. With this concept, I aim to promote happiness, movement, and fun for the wearer and to suggest the mental and physical benefits of dance.


Process

1. Brainstorming: I kicked off my brainstorming with a similar exercise to what we did for our Speculative Wearable assignment: by listing various emotions, then the everyday items that we wear. After this, I (initially) decided to create a dance-detecting skirt. (More on this later)

img_61152. Research: Next, I conducted some online research about dancing as a healthy form of movement! 

According to Danceworks, it’s pretty ‘impossible’ to dance and stay in a bad mood, because the act of dancing itself is an exercise. Exercise releases endorphins, which reduces the perception of pain and increases positive self-image in our brains. Therefore, dancing makes us happy. According to Greatist, these are some other benefits of dance:

  • Improves agility and flexibility
  • Improves balance and coordination
  • Improves cardiovascular health
  • Improves muscle tone and strength
  • Maintains and builds bone strength
  • Aids in weight loss or maintenance
  • Improves memory and cognition
  • Improves mood
  • Reduces stress levels
  • Provides an opportunity to socialize
  • Boosts self-esteem
  • Is easily adaptable to meet your needs

    3. Initial Interaction Flow:
     After deciding on my idea, I created a flow map that helped me understand the inputs, outputs, and the overall function of my wearable better.

4. Initial Sketches: Then I made some quick sketches! Here are the initial drawings I created based on my original skirt idea. I intended it to have LEDs sewed along the top that would light up with movement.
slide-16_9-1-1

5. Idea Shift: After some initial reflection and planning, I decided to change the direction of my project to be a belt instead of a skirt. This would allow for more ease of wearing (rather than having to put on the same skirt each time they go out dancing, the user can wear a belt with anything, anytime) and more inclusivity (it can be worn by anyone who wears pants, skirts, trousers, and more).

6. Inspiration Photos & Initial Sketches: After deciding on a belt, I gathered some inspiration photos to decide how/where to place my CPX. In the end, I decided to place it in the center as it would allow for the most secure hold – and the wearer would be able to see the neopixels easily.

slide-16_9-77. New Sketches & Flow: As outlined in my sketches below, the switch of the belt is activated by putting the belt on. Looping the end of the belt through the belt buckle would make the conductive fabric on opposite sides of the belt touch, activating the switch. (Please zoom in to see the detailed steps regarding input / output and what happens while the wearer is using the wearable.)

8. Circuit Diagram: I created a circuit diagram of how I’ll be sewing the conductive thread (the dotted lines) to connect A1 and GND to the conductive fabric pieces.

slide-16_9-9

9. Putting everything together: I’m terrible at executing hands-on projects, so I spent a lot of time testing out how exactly I should make my wearable. This is the pre-existing fabric belt I used for this project — it was too long for my waist as it was originally a coat belt, so I cut the end of it to fit.

img_5971I fastened the belt around my pants and held the CPX at the center, trying to figure out how to sew everything together. Then, I tried placing different types of white fabric on top to see how the neopixels would be diffused. I also determined that the cord of the CPX would loop around the side of my waist (see below).

img_6036 img_6050 img_6088

With the belt around my waist, drawing black lines with a pen helped me determine where to place the conductive fabric so that they align perfectly when I buckle the belt.

img_6120

Before sewing the conductive fabric on, I tested the alignment of the pen lines by taping on some pieces of non-conductive fabric.

img_6122

Once I was happy with the placement, I cut out the conductive fabric to fit on the belt, and sewed them on.

img_6124img_6125img_6139img_6142 img_6144

Then I placed my CPX in the center, and cut out a small slit on the side to pull my cord through. This would hide the cord underneath my belt, but leave a gap to have it ‘poke out’ to connect to my CPX.

img_6149

Next, I sewed conductive thread through both A1 and GND, and continued it down each sides of the belt. One sewing ‘path’ connected A1 to one piece of conductive fabric, and the other connected GND to the other piece of conductive fabric. It’s not pictured here, but to stabilize the CPX a bit more, I also looped non-conductive, regular thread through another hole in the CPX and sewed it through the belt. Here is how I tested whether the switch was working: Alligator Clip Test

Lastly, to cover up my conductive thread and CPX (and to make the belt a bit less flimsy), I wrapped a cut-out piece of linen pillowcase around the fabric and secured it, leaving only the belt buckle and conductive fabric exposed. The pillowcase was thick enough to make the belt more secure, but transparent enough to let the neopixels show through.

img_6196

10. Makecode: Of course, I was simultaenously working on the code for my wearable. After many iterations, this is my final code.

  • The wearable’s switch is activated by A1. If the switch is turned on, the neopixels are set at red. At start, it plays the sound ‘power up’.
  • If the wearer is still for 1000 ms, the wearable plays the sound ‘wawawaa’, telling them to move.
  • On each shake, the neopixels on one side turn green one by one, playing the sound ‘ba ding’ until it reaches 5 shakes. This indicates a series of movements that add up to ‘dancing’. At this point, the wearable plays the rainbow animation with the sound ‘magic wand’.
  • In each of these steps, if the wearer stops moving, the ‘wawawaa’ sound will play.

Here is a video of how the switch of the belt is activated. (P.S while I was fastening my belt, the conductive fabrics started touching and the wearable detected that I wasn’t moving — hence the ‘wawawaa’ sound playing while I’m still adjusting) Video 1

Here is a video of how the belt tells me to start moving, and how each shake leads up to the ‘continuous dance’ indication. Video 2


Reflections & Next Steps

If I had more time and resources, I would have wanted to use a different material for my wearable. The fabric of the belt was quite flimsy as mentioned before, and I suspect that it might have contributed to some slight glitches that appeared in my switch once in a while. Maybe the conductive thread wasn’t sewed tightly enough, or it got loosened because of the soft material! I would also like to program a way of detecting music as well, if I had the chance to revisit this project.

Assignment 1 — Speculative Wearable: Kate Jung

Process:

I began my brainstorming process with the ideation exercise, and came up with three different combinations with 7 total variations. After completing my ideation process for the earrings, I decided to move forward with earrings as the form of my speculative wearable.

processprocess-2process-1


Concept & Objective:

My wearable is a pair of earrings that detects high levels of anxiety or stress on the wearer, then activates sound therapy to provide them instant, discrete support.

As someone who experiences anxiety (and know people with other mental health conditions such as PTSD), I always thought it would be great for there to be a device that alleviates stress in real-time, and help those who need calming down — even if the impact is small. Therefore, my concept for the wearable is a pair of earrings that is constructed of two parts:

First, the input: a gemstone-like stud is pressed against the earlobe and measures stress with photoplethysmogram (PPG) technology, monitoring the pulse through blood flow in the skin. Following similar devices on the market (such as the Apple Watch and Samsung Gear), the technology allows light to be emitted through LED, which gets reflected by blood present under the skin. The reflected light is absorbed by photodiode to detect blood flow.

Because earrings are worn flush against the skin, this would create a better quality of contact between the device and the skin, and provide comfort to the wearer rather than having to wear clunky fitness watches or heart-rate monitors. Also, while wrist or skin-based devices sometimes shift around depending on a person’s movements, earrings can provide a more stable reading. According to research by ‘The Ear-o-Smart Smart Earring’ — another form of wearable earrings — physicians regularly use the earlobe to monitor the heart rate and blood oxygen of patients because the high blood flow in the area provides greater accuracy.

Second, the output: Once the top part of the earrings detects high rates of blood pressure, the bottom part (the part of the earrings that ‘dangle’ underneath and is larger, with a shell-like shape) would be triggered. This is a mini audio transmitter. The ‘holes’ that are dotted along the lines of this area would be where audio would be transmitted through the speaker.

In science, there has always been strong evidence that music has mental and physical health benefits. Audio such as vibrational therapy or meditation also offers therapeutic benefits to the body.

According to the Center for trauma, Stress and Anxiety, these are some benefits of sound healing:

– Immediate reduction in anxiety and stress
– Improves symptoms of depression
– Improves stress management
– Promotes sleep
– Reduces blood pressure
– Increases blood circulation
– Enhances memory, concentration, and focus
– Improves mood and sense of happiness

There are different forms of audio that can be therapeutic to those who are experiencing anxiety / stress, including alpha waves, vibrational waves, meditation sound therapy — or even just playing their favourite, relaxing song. I would imagine my wearable would allow the users the capability of progamming their own, preferred sounds onto the device depending on what helps them the most.

In conclusion, these earrings can be worn by anyone in the world who experiences stress and anxiety, but may have a larger benefit for those who experiences regular forms of mental health issues such as anxiety attacks, depression, etc. The earrings can also be worn in all-day, every-day use as they shouldn’t look too different than a normal pair of earrings (my paper prototype actually ended up a little bit larger than I would imagine it). Because it’s comfortable to wear and identical to the feeling of wearing normal earrings, people would be able to wear it for extended periods of time.

The Ear-o-Smart Smart Earring: The Ear-o-Smart is a smart earring that is designed to function as a fitness tracker. It is able to detect heart rate, calories, as well as activity level. (The information I included above about the earlobe as an ideal location for heart rate tracking was sourced from their website.)

Pip: This device is a biosensor that senses electrodermal activity (EDA), the electrical changes at the surface in the skin, to detect stress response. When the wearer grasps it between their fingers, this information is communicated via Bluetooth technology to Pip’s iOS and Android Apps.
