In Inbodied Interaction 101, we considered the Physiology and Anatomy of the body via three associated interactions that reflect an inbodied state: 1. inbodied adaptation in response to the in5 and C4 over Time and Context in order to maintain 2. homeostasis via 3. metabolism. We called this adaptation process "tuning."In 102 we build on this foundation to consider the physiology tuning. In particular we will look at a series of inbodied interactions: the neuro-endocrine system interaction with the organ systems that cue adaptive responses from genetic signals to fat metabolism; the autonomic nervous system and the limbic system's interactions that affect volitional/non-volitional interaction. We will introduce the components of the brainstem, basal nuclei and cerebellum that support interoception around self-Tuning. Within this framing, we will look at the strengths and limits of non-invasive measures of these processes (eg, HRV, EEG, blood oxygen saturation, qualitative responses). Outcomes will familiarity with how we function as inbodied complex systems, with worked examples of how the physiology of tuning can be translated into interactive designs to support health, wellbeing, performance in new ways.
