With the biofeedback programs, users learn how to detect bodily functions, which otherwise go unnoticed. Processes, activities and signals in the body (bio) can be detected using feedback. The training parameters are measured and displayed – as well as linked to acoustic or visual signals – through the training software. These signals are also transmitted through the screen and/or speakers. This makes you aware of various physical processes. You can instantly see and/or hear what your body is doing.
