Stéfanie Kay – Helia

Most people spend almost 90% of their time indoors, lit by artificial lights which, unlike the sun, do not change colour or intensity during the day, thus disturbing the circadian rhythm.

Helia follows the user throughout the day – from waking up to falling asleep – varying its light intensity and colour and thus improving the user’s concentration, productivity, quality of sleep, mood, etc. Thanks to its modular head, Helia can be used to create either ambient or work light.

The project, carried out in collaboration with the EPFL+ECAL Lab, turned out to be a very rewarding experience. Mixing different skills in one project was both interesting and instructive.
