Health care is increasingly being viewed as a team effort between practitioner and patient, with the recognition of the quality of interaction as a potential problem in such team effort. The paper addresses this problem, providing a solution that enables to record, monitor and analyse the quality of such interactions. It is based on a visual language used to represent the quality of interactions. The shape and behaviour of the visual elements and expressions are based on the physicality of human movement. The visual expressions resemble musical scores. As the behaviour of the visual elements corresponds to our bodily knowledge, commonly understandable to humans, the information about the quality of the interactions, expressed in this language is easily digestible by people with a broad range of backgrounds. The paper presents also the visual reasoning technique that works with the setting and a high-level view of the underlying ICT architecture. The practical utilisation is demonstrated with an example from occupational therapy.
