Description:
Hello everyone,
I've been experimenting with the Polar H10 to monitor breathing patterns and I'm curious if anyone has successfully managed to get real-time visualizations of breaths.
My current setup involves post-processing the data of about 2 min with high-pass and low-pass filtfilt butterworth filters, which provides a decent representation of the signals when analyzing data for specific durations. However, when attempting to visualize the data in real-time, I face issues. The accelerometer from the Polar device operates at 200Hz, I'm sending 200 values per second for processing. So, I notice discontinuities at the end of each 200-samples, which affects the continuity and virtualization looks nothing like a breathing signal.
Has anyone faced a similar challenge or managed to overcome it? If anyone can share any strategies or adjustments I have to make to handle these discontinuities effectively. Any insights on filter adjustments, data handling techniques, or even alternative approaches to achieving smooth, real-time visualization would be greatly appreciated.
Thank you in advance for sharing your experiences and solutions.

We use real time PPI for display in some experiments, but due to the fact that the updates are batched (typically in 5 samples), we need to have about 2-3 seconds delay on the UI to make it look nice.
@orestesgaolin Ohh okay I see. Thank you for your reply.
