Imagine a world where your music not only complements your mood but is finely tuned to your changing emotions. In this case study, we look into the design journey that blurs the lines between technology and human connection. Neurotune — an app designed to harmonise with your emotions, guided by the fluctuations in your brainwaves detected by the Neurosity Crown.

Specialising in wearable brain-computer interfaces (BCIs), is Neurosity, a company dedicated to pushing the boundaries. Their flagship product, the Crown headband, unlocks the potential of direct communication between the brain and external systems. At its core lies EEG (electroencephalography), a non-invasive neuroimaging technique capturing and interpreting the brain’s electrical signals.

Worn on the head, the Crown’s strategically placed electrodes measure activity in different brain regions, translating it into interpretable data. Particularly attuned to Gamma brainwaves associated with concentration, it provides real-time feedback on cognitive states.
