The paper presents an example of a wearable system for caring for the elderly. It focuses on the relationships between the individual components of this system from a macro ergonomics point of view. The protection of older people has been identified as a standard of well-being that, in highly developed countries, is evolving from a passive social security model to an active, holistic paradigm. This new paradigm is aimed not only at prolonging life, but also at ensuring its highest quality, dignity and full social integration. This new standard goes far beyond pensions and basic healthcare, becoming a measure of a country's humanitarian maturity and social advancement. The design of such telecare systems should be user-oriented in accordance with the principles of universal design. Defining the relationship between humans and work elements is crucial. Its purpose is to ensure hygiene, safety and comfort at work, while maintaining high production efficiency.
