#selfresearch — Public Fediverse posts

At today's Open Humans #selfresearch chat, Abhik shared his work on making in-home video recordings to classify the activities he does throughout the day.

One big challenge he needed to tackle: How to minimize the amount of data this generates, he blogged about this here: https://medium.com/@abhik.ch6/getting-a-500x-reduction-in-video-file-size-for-my-in-home-activity-recognition-4ff897840236

At yesterday's #SelfResearch call, someone noticed that the footer on https://tzovar.as put out that I "slept 0 hours". Weird, as the data itself was logged correctly on my phone.

After some sleuthing around the data, it turns out that the "inBed" data of Apple Health keeps returning only zeroes for each day - ever since updating to iOS 18. 🤦 This is the problem with #quantifiedself integrations: Manufacturers change their data models (and algorithms) without making this clear to users…

As Monday morning might be a better time to share than Friday afternoons: Check out our latest preprint on creating a shared knowledge base for #selfresearch, #personalscience & #quantifiedself. Katharina did a really great job on co-designing and testing the "Personal Science Wiki" with practitioners to make sure it fits their mental models of the practice!

This seems like a fun #selfresearch project, comparing a vegan to a non-vegan diet. https://theconversation.com/i-self-experimented-to-compare-a-vegan-diet-with-eating-meat-this-is-what-i-found-out-212213

I noticed that my respiratory rate started started being an outlier more often recently. I wondered if that was one of the outcomes of (again) stopping to smoke in February?

Plotting this year's respiratory rate compared to my own background data (collected since 2018) it looks like there's quite a big effect!

Not only is it down, it also goes against a seasonal effect – looks like my resp. rate usually goes up in (north. hemisphere) summer!

At the end of last year I shared a little heuristic I made – for whether my #wearable data said I might be under the weather or not.

Last week I remembered that I actually have some data to pseudo-validate it: For now 1000+ days I've been tracking whether I'm sick & if so what symptoms I have. Turns out that my heuristic of “combined number of physiological deviations" doesn't work too badly!

A full write-up is here: https://wiki.openhumans.org/wiki/A_heuristic_for_feeling_fine#EDIT_2023-06-08:_Using_historical_data_to_.22validate.22_approach

As I had to set up my development environment on my new computer I used the occasion to update the Oura Ring integration for Open Humans. It now also fetches data from the version 2 API, including intra-day heart rate recordings! You can find it at https://oura.openhumans.org
