Light – Heart – Sync


Photoplethysmography (PPG) is a technology that allows the Heart Rate Variability (HRV) to be measured simply via mobile phone.

PPG is measured via reflection through the illumination of the skin using an LED (e.g. the mobile’s flash) and through detection of the amount of light that is reflected by a photodetector or a camera located next to the light source.

From HRV, we provide Ultra Sync which is a measurement of the level of synchronization between fans.


UVIBES’ peaks reveal the instant emotional response of the audience to the content, ads or live event. The second-by-second data allow to track the key moments , especially the lows and highs of response and engagement.
