Deeper Mind

Deeper Mind uses Gemini 3 and EEG data from a Brainbit to visualize brain wave data, understand current state, and guide the user through a 7 minute meditation session to get achieve a "deeper" state

Inspiration

I was inspired by the effectiveness of guided meditation and consumer accessibility to measure brainwave data. I thought there must be a way to leverage this to have a more dynamic experience during meditation and really take advantage of data and live insights to tune an experience.

What it does

It integrates with the Brainbit EEG headset through Bluetooth and reads and displays live brain wave data. It uses Gemini to analyze the current state, then guides the user through a 7 minute "Deep Flow Session" to achieve a "deeper" state. It takes readings throughout the session to prompt the user and provide a custom experience based on their actual data. There is a demo session available with synthetic data feeds, so anyone can demo the experience.

How we built it

I used Antigravity and Gemini 3 Pro to code my project, and Gemini as a brainstorming partner to plan. I am using Gemini 3 to analyze the brain wave data and to dynamically guide the user feedback over the session.

Challenges we ran into

I had some trouble reading the Bluetooth EEG data, but was able to quickly resolve it by looking for console errors and iterating back and forth.

Accomplishments that we're proud of

I'm proud of bringing this idea to life and dealing with a hardware integration that seemed like it would be impossibly hard. With Gemini 3 as a coding partner, the seemingly hard part of integrating hardware was really accessible and it allowed me to focus on tuning the more interesting parts of the user experience and what I found to be missing in other applications. Leveraging the low latency low cost Gemini 3 Flash Preview allowed me to make sense of the EEG data in real time in a useful way.

What we learned

This was the first time I implemented a Demo mode inside an application, which I think is important for new users to understand before fully committing to using it. I also dealt with hardware integration via Bluetooth data in a much deeper way than I had before.

What's next for Deeper Mind

I'd like to extend the Deeper Flow Session and improve the experience visuals, music and narration, perhaps include a log over time. It would also be nice for users to be able to get live data from more common wearable devices such as phones and watches.
