About 'Log Flower'

'Log Flower' is a digital plant artwork conceived and produced by Konel Inc. The piece grows by absorbing the emotional atmosphere of a space. Using Empath's voice emotion analysis technology, it detects emotions in human speech in real time and transforms from seed to sprout to bloom, changing its shape and color accordingly.

The flower changes color based on detected emotions: white (neutral), yellow (joy), blue (sadness), and red (anger). As a digital art piece that reflects the ambient emotional climate over time, it offers visitors an interactive experience where speaking to it causes the plant to grow and evolve.
