PreFix SystemsThe movie your client chooses becomes the feedback.
PreFix turns a client's own forehead skin temperature or heart rhythm into a picture and sound that respond in real time, so they can learn to influence it. pIR HEG and HRV in one app, on Mac and Windows.
Built around what clients will actually sit through
Training works when the client stays engaged. PreFix lets them watch what they want while the session runs underneath it.
Any content
Streaming services in the app, DVDs, your own video files, or built-in scenic scenes for quiet sessions.
Two ways to train
Operant: the movie pauses when the signal drops below threshold and resumes when the client recovers. Continuous: picture size, clarity and volume follow the signal moment to moment.
HRV coherence
Paced breathing with a guided physiological sigh, and a live coherence display, using a Bluetooth heart-rate strap.
Clean records
Session summaries with total time and pause time, a client history, and session saving to EEGVault for practices that use it.
What the signal is
pIR HEG reads forehead skin temperature without touching the skin. As the small blood vessels of the forehead warm and cool, the temperature shifts with the client's state. It is an autonomic signal, like hand warming, read from the forehead.
The training is in the dips and recoveries: moving into a state and finding the way back out. PreFix makes those moments visible to the client through the movie, and visible to you through a live trace.
