Where did the idea of Human Centered Design come from?
The Human Centered Design concept puts people in the center , their needs, expectations, possibilities, fears and limitations.
The creator of the theory is Donald Norman, who in the 1980s conceptualized a process that returns the end result of a project to the user, which is to serve him without any problems.
Human Centered Design resulted in the Human Centric Lighting (HCL) project, initiated in 2013-2016 by the European Commission, with the aim of broadening the knowledge in the field of modern lighting and supporting practices emphasizing technology development in this area. The findings of these activities define the impact that office lighting has on the well-being and productivity of employees . The existing standards only regulated the level of light intensity, glare or color rendering - they in no way directly referred to the comfort of work of employees, only indirectly spoke about the impact of poor lighting parameters on health.
The main recommendation of the project is that office lighting is optimized for the circadian rhythm . Daylight regulates our biological clock, stimulates our activity or makes us rest. This is because it moves receptors on the retina of the eye that signal to our body at time of day. As the sun moves, also change the color temperature of the light, its angle of incidence, intensity and quantity .
