Inspiration

Each year, nearly 1.5% of the U.S. population-- or 3.3 million adults-- endures panic attacks or is suffering from an anxiety disorder that can have debilitating effects on their everyday life.

Panic attacks and anxiety disorders can be difficult to formally diagnose but are typically defined as the abrupt onset of intense fear or discomfort in situations where most people wouldn’t feel worried.

There’s no “cure” for panic attacks and there are few-if any-commercially available tools for patients to identify and monitor their own panic attacks without a doctor’s help. That’s where we come in!

What it does

A device that is able to anticipate panic attacks through physiological indicators and aid in stabilizing / calming individuals undergoing panic attacks by showing physiological improvement and monitoring effects of meditation, breathing, and other panic attack relief techniques to help individuals learn what truly works best for them.

How we built it

Our device uses a push button to control images, pulse sensor to track heart rate, microphone to track breathing rate, and a 9-axis IMU to identify trembling motions. The green LED flashes at the heart rate, and the yellow LED flashes when a panic attack begins. A 2.2 inch LCD graphic display provides calming images and everything is integrated into a single wearable bracelet device.

In our internal algorithm, the pulse sensor identifies heart beats over a period of time to calculate beats per minute. The microphone picks up changes in breathing volume to identify the time between each breath and calculate breaths per minute. The 9-axis IMU evaluates every 6 consecutive position readings to isolate back-and-forth movements for trembling motions. When the heart rate rises above 120 bpm, the breathing rate rises above 25 breaths per minute, or if trembling occurs, then we have crossed the threshold for a panic attack and the user can press buttons to see calming images from a graphics card

Challenges I ran into

We had difficulties with making all the sensors work simultaneously and combining the output data to create a complex algorithm, but we successfully overcome this challenge.

Accomplishments that I'm proud of

Compared to other similar devices, idyll has several advantages: first, it can be worn all day for continuous monitoring. It collects inputs from 3 different sensors every second and allows users have access to their physiological data through serial connection-- in the future, this could be a web app. We are proud of creating a product that can combine multiple sensors at once to create a better user experience with more accurate data analysis algorithm.

What I learned

We learned to create a variable which can keep track of multiple sensors such as IMU, LCD Graphic display with an SD card, and microphone simultaneously.

What's next for Idyll

We are planning on creating a webapp that makes the collected data open to both our client and his/her doctor to make the treatment and data tracking easier for everyone. Our aim is to make the user experience as smooth as we can.
