Yogoddess

Inspiration

In Greek mythology, Artemis was the goddess of the moon and nature. She protected women and helped them find balance between strength and peace. She guided people through dark forests under the moonlight. Today, many women who practice yoga face similar problems. They want to find balance in their lives, but yoga can be difficult. Many people get injured because they don't know the correct way to do poses. Others cannot focus during meditation or don't know when their body is too stressed.

We wanted to create something like Artemis - a helper that protects women during yoga practice. We thought: "What if technology could help people practice yoga more safely and mindfully?" This is how we got the idea for Yogoddess. Just like Artemis protected women in ancient times, our system protects women during yoga practice. It helps them listen to their bodies and practice safely.

What it does

Yogoddess is a smart system that watches over you during yoga practice. It works like a caring friend who understands your body and helps you practice safely. The system uses three types of sensors that work together to understand what is happening with your body during yoga.

The first part of our system tracks your focus by watching your eyes. It can tell when you are paying attention during poses and meditation, and when your mind starts to wander. This helps you stay present and get the most benefit from your practice.

The second part monitors your muscle strength by measuring how hard your muscles are working. This makes sure you are doing poses correctly and not pushing your body too hard or too little.

The third part detects your stress levels by checking your heartbeat and how it changes. This helps you know when you are calm and when you might be pushing yourself too much.

The system gives you gentle feedback through lights, sounds, or soft vibrations that don't disturb your peaceful practice. This feedback helps you do poses with correct form, stay focused during your practice, avoid getting hurt, build strength slowly and safely, and understand your body's signals better. Like Artemis guiding people through the forest with her gentle wisdom, our system guides you through yoga practice with care and understanding, helping you connect more deeply with yourself.

How we built it

We built Yogoddess using both hardware and software components. The hardware includes EOG sensors for tracking eye movements, which measure the electrical activity around your eyes to see where you look and how focused you are. We also use EMG sensors that are small devices that stick on your skin to measure muscle electrical activity during yoga poses. ECG sensors monitor your heart's electrical signals to track heartbeat and stress levels. All these sensors connect to an Arduino microcontroller, which collects and sends the data to a main computer for processing.

For the software, we created programs that clean and analyze the data from sensors using Python programming language. We built machine learning programs that learn to recognize different yoga poses and stress levels. We developed an easy-to-use phone app. We also created a feedback system with programs that decide when and how to give you helpful advice.

Challenges we ran into

We faced technical problems during development. Because of equipment issues, the signals from different sensors interfered with each other, making the data very noisy and poor quality. The EOG, EMG, and ECG sensors sometimes created electrical interference that made it hard to get clear readings. The sensor data was often messy and hard to read, especially when people were moving. We had to use special computer programs to clean the data and filter out the interference. We needed the system to work very fast to give immediate feedback, which was difficult because processing data takes time. We had to find the best places to put sensors so they don't bother people during yoga but still work well. Since everyone's body is different, we had to make the system work for people of all sizes and fitness levels.

Accomplishments that we're proud of

We successfully integrated three different types of biomedical sensors (EOG, EMG, and ECG) into a single cohesive system, which was a significant technical achievement given the complexity of managing multiple signal types simultaneously. Despite facing major signal interference challenges, we developed effective data processing algorithms that can filter noise and extract meaningful information from the sensor readings.

We created a working prototype that can accurately detect different yoga poses and provide real-time feedback to users. Our machine learning models learned to recognize when someone is focused versus distracted during meditation, and can identify when muscle engagement levels indicate proper form versus potential strain or injury risk.

Most importantly, we built a system that truly embodies the caring, protective spirit of Artemis. Yogoddess provides gentle, non-intrusive feedback that enhances rather than disrupts the peaceful yoga experience. We successfully created technology that feels more like a wise companion than a cold monitoring device.

We're also proud of making the system accessible and user-friendly. The mobile app interface is intuitive, and the sensor placement is comfortable enough for extended yoga sessions. We validated our approach through testing with real yoga practitioners who confirmed that the feedback helped them improve their practice safely.

What we learned

We learned many important lessons during this project. Working with multiple biomedical sensors taught us that signal interference is a major problem when combining EOG, EMG, and ECG sensors. We discovered that electrical signals from different sensors can interfere with each other, creating noise and poor data quality.

Body signals are very complex, and everyone's body is different. The same signal can mean different things for different people. Context is very important because the same heart rate can be normal during hard poses but show stress during easy poses. We discovered that giving a few useful tips is better than giving too much information. Hardware placement is critical - we learned that even small changes in sensor position can greatly affect signal quality.

What's next for Yogoddess

In the short term over the next six months, we plan to add support for more than 100 different yoga poses from different yoga styles. We want to show users how they improve in flexibility, strength, and focus over time. We also plan to create tools for yoga teachers to help multiple students in classes.

For medium-term plans over the next 6 to 18 months, we want to build a smart system that creates personal yoga sessions based on what each person needs. We plan to make a place where yoga practitioners can connect and learn from each other safely. We also want to work with existing yoga apps and studios to help more people use our system.

Our long-term plans for the next 1 to 3 years include expanding beyond yoga to include meditation, breathing exercises, and other wellness practices. We want to work with doctors to use wellness data to help prevent health problems. We plan to make the system available in many languages and adapt it for different cultures around the world.

For future research, we want to explore new ways to measure body tension, nervous system activity, and energy levels. We are interested in studying brain signals to better understand meditation and mental focus. We also want to include things like air quality, light, and sound in the wellness system to create a complete environment for practice.
