This blog post was written by, and highlights the Fall 2014 final project of, EMAC undergraduate student Justin Ozuna. Follow him on Twitter @TheOzunaVerse. The assignment for which he made the project can be found here.

Pet ownership is a way of life in the United States. According to humanesociety.org, more than 80 million dogs are pets in U.S. households. Eighty million! For perspective, there are an estimated 316 million people living in the United States. Nearly 47 percent of households own at least one dog, and the upward trend doesn’t show any signs of decline in the near future. In fact, pet ownership has nearly tripled since the 1970s.

Where there are numbers, there is a thriving industry. Americans will spend $58 billion on all pets combined this year. Walk into any store and there’s likely to be an aisle (or two) of pet food, snacks, toys and accessories. What you won’t be able to buy in the store, however, is time. After a long day of work and a full schedule of evening activities, Fido is ready for a long walk. The problem is that there’s not always time to take your pet for a stroll in the neighborhood before the sun goes down and the stars fill the sky. Walking your pet at night means you’re at the mercy of overcautious drivers and hyper-focused neighbors to stay safe.

A panic attack is a sudden surge of overwhelming anxiety and fear. Your heart pounds and you can’t breathe.

Relaxation techniques such as meditation, controlled breathing, and grounding can reduce anxiety and increase feelings of relaxation and emotional well-being. However, it is not always easy for a victim of a panic attack to be aware of what is physically happening to them at the onset of the attack and therefore they are unable to treat and calm themselves in the moment.

Additionally, panic attacks rarely happen in a controlled or private environment. Being exposed during a panic attack can heighten the overwhelming feelings of anxiety and fear and lead to complications if an attack occurs in an inopportune time such as during work or in a social setting.

Using sensors that measure specific physiological functions such as heart rate, biofeedback teaches an individual who suffers from Panic Attacks or Panic Disorder to recognize the body’s anxiety response and learn how to control them using relaxation and grounding techniques.

This project attempts to address the needs of a person who suffers from frequent panic attacks or panic disorder by allowing them to be aware of their physiological state in order to reduce the symptoms of a panic attack and aid in reducing the duration of a panic attack. Panic attacks are distinguished from other forms of anxiety by their intensity and their sudden, episodic nature. Through the Anxiety Cuff device a victim can take control of an attack and return to normal functionality as quickly as possible.

A person who is using the anxiety cuff will wear the Polar Heart Rate Transmitter which will measure their heart rate every second.

They will put the cuff on their arm, as pictured below, and go about their usual daily activities.

While an individual’s heart rate remains constant, there will be no change in the device and some light to moderate movement and exercise will have no effect on the device as well. However, as the wearer begins to experience the symptoms of a panic attack their heart rate will begin to dramatically increase.

Once the Heart rate increases to an exceptionally high level, the Arduino triggers the vibe board to apply vibration to the pressure point at the underside of the wearer’s wrist.

This notifies the wearer that they are experiencing the physiological symptoms of a panic attack and allows them to begin integrating relaxation and grounding techniques to halt the attack at it’s onset.

If the attack is acute, and continues to progress the vibrating motor will continue to apply pressure to the wearer’s wrist while the heart rate is elevated. What this continued pressure will do is to allow the wearer to focus on the vibration and the physical environment – grounding themselves and allowing them to begin the process of re-associating their internal and physical states to help the attack subside.

Once the heart rate had reduced the lilypad vibe board will turn off, and the wearer can resume their normal activites.

SMU was decorated and ready

Early on a Saturday morning, 11 Fashioning Circuits volunteers, ranging from 11 to 50-something years old, trekked down to Southern Methodist University for the Fall installment of the Design Your World conference, for 4th and 5th grade girls. Our volunteers included current and former students, parents, daughters, and friends from neighboring universities.

The event was organized by the Dallas Society of Women Engineers (SWE) in partnership with the SMU chapter of SWE . They invited Fashioning Circuits to lead an all day “Electronic Fashion Camp” workshop for twenty girls. In the morning, the workshop included an opening discussion about Fashion as Communication, an introduction to the concept of physical computing, and a coding workshop and time for geeking out and messing around with the Lilypad Arduino. The afternoon was focused on a take home project – a twinkling headband!

It was a really fun day. The girls who attended that day learned a lot but we also learned a few things. Lessons that we learned include that you can never have too many pairs of scissors and that for future workshops we should not be tempted by the inexpensive sewing needle multipacks – many of the needles had eyes that were so tiny they were very difficult to work with! This was our first workshop for a group this young that included a take home project. Our strategy of gluing down the LilyTwinkle, LEDs, and battery holder in advance worked quite nicely.

According to the Dallas SWE’s writeup of the event, 82% of the kids responded that they would attend a Design Your World event again, and 88% responded that they would recommend the event to others. We hope that our numbers for Fashioning Circuits were even higher.

The day made an impact on our volunteers as well. EMAC senior, Lance King, writes, “When I first got involved, I had no idea Fashioning Circuits would be such an impactful experience. The young girl I was mentoring through this project was so patient and inquisitive! Once we finished working on her head band, I looked her in the eyes and said, ‘The batteries are in now…Do YOU want to turn it on?!’ She nodded her head and as she flipped the switch…her eyes lit up and sparkled brighter than any LED could hope to! It felt SO amazing to be a part of a child’s educational experience in that way. I don’t think she’ll forget it and I know I won’t.”

In a few weeks, the Fashioning Circuits crew is going to lead a workshop on Open Source Fashion at the Girl Scouts College Journey — Teaming for Tomorrow summer camp at UT Dallas. In addition to introducing students to open source and the Lilypad arduino, we will be leading 25 high school students in a take-home project. Each student will get to make and take home a twinkling wrist cuff with four colored LEDs, made from the LilyTwinkle and Lilypad LEDs. Kim Knight just finished making the prototype and will be training the trainers soon. We only have four hours total for the workshop so we’ll cut out all of the fabric and sew the first few seams in advance, but the tutorial below covers the entire process from start to finish.
