About the SelfSense Practice

SelfSense did not start as an app. It started as a practice — a somatic research session where participants stepped into a room and discovered what happens to a body when it knows it is being measured.

The first iteration was presented at Martin Gropius Bau in Berlin in September 2022, as part of the broader EightOS bodymind operating system developed by Dmitry Paranyushkin. The setup was deliberately simple. Sensors. A screen. A few movement instructions. What it revealed was less simple. Once participants saw their own variability rendered back to them in real time, the body stopped behaving like a body and started behaving like something performing itself.

That observation is the practice.

What the Practice Investigates

The premise behind SelfSense — both the original sessions and the current app — is that real-time diagnostic tools are not neutral. The moment you measure something about a person and show it back to them, you've changed what they're doing. Heart rate variability is no longer just a number; it's a target, a mirror, a small ongoing negotiation between attention and biology.

Most consumer wellness apps treat this as a feature. Show the user their HRV, and they'll work to improve it. SelfSense treats it as the actual subject. What does it feel like to be watched by an algorithm? What happens to your breathing when you know it's being scored? How does behaviour change when surveillance becomes self-surveillance?

The practice repurposes the same machinery that normalises and optimises in clinical and corporate contexts, and points it somewhere else — toward play, toward noticing, toward the kind of strangeness that only shows up when you can see your nervous system from outside.

How a Session Works

The sessions adapt across formats. Some are immersive movement experiences with multiple participants. Some are collective ideation sessions where the sensors become a shared vocabulary for talking about bodily state. The common thread is that participants don't just generate data — they engage with the feedback as material.

A typical sequence:

  • Baseline. Sit, breathe, watch the sensors register your resting state. Notice what the numbers do when you stop trying to influence them.
  • Provocation. A movement task, a breath pattern, an instruction to break a habit. The sensors track what changes.
  • Observation. The most important part. What did the feedback show that you didn't expect? Where did you try to game it? Where did your body do something you couldn't have predicted?
  • Discussion or reintegration. Sometimes verbal. Sometimes more movement. Sometimes silence.

The DFA alpha measure is central because it gives a structural reading rather than just an amplitude. You can be calm and rigid (alpha drifts high), or stressed and chaotic (alpha drops low), or — the target — in a fractal state where your variability has internal structure across scales. The practice trains you to feel the difference, not just see it on a screen.

Why It Became an App

The original sessions were beautiful but bounded. A few dozen participants. A specific room. A specific moment. The app exists to extend the practice into the rest of life — into the breath you take at your desk, the walk to the shop, the moment you notice your shoulders are climbing toward your ears again.

Everything in the SelfSense app — the Apple Watch integration, the fractal breathing entrainer, the DFA alpha tracker — is a translation of something that happened first in a session with a body, a sensor, and someone willing to be curious about what their own nervous system was up to.

Where the Lineage Goes Next

The practice is still evolving. SelfSense the app is one branch. Fractal Choreography is another — the same sensors and the same DFA analysis applied to dance, music production, and live performance, where the goal isn't health but artistic expression. The SelfSense Event Server is the technical backbone that lets multiple sensors and multiple participants share a session in real time.

What ties them together is the underlying commitment: technology that helps you notice yourself more carefully, not technology that tells you what to do.
