Heart Bloom

Flowers for Life and Love

Heart Bloom is a biofeedback device that collects heart rate data and visualizes it with the assistance of a pen plotter. The path and rhythm of the pen’s movements are dynamically coupled to physiological information, such as heart rate variability, creating a new means for visualizing and monitoring personal medical information. Heart Bloom Illustrates the visitor’s heartbeat into a floral graphics, which reflects the natural biorhythm inside the human body. By interacting with Heart Bloom, participants can see, hear and feel their physiological signals transformed into a unique flower drawing on the paper.

HEART BLOOM for Charity at Dutch Design Week, 2017

“Let’s make every heartbeat count!”

In 2017, Heart Bloom served as a charitable initiative that aims to help children with congenital heart disease (CHD). Heart Bloom invited visitors to donate their heart rate data by creating a personal heart bloom card. Then the participants could receive their heart bloom card by making a donation to the Hartstichting, the Dutch Heart Foundation. The donation went towards the foundation’s efforts to improve the chances of children with heart disease.

With Heart Bloom, we attended a series of charitable public activities organized by the Hartstichting. At these events, we brought Heart Bloom to children with heart disease. The interaction with Heart Bloom empowered them to see, hear and feel the ‘seed’ inside the body blooming into a ‘flower’ with every beat of their heart.

Heart Bloom aimed to bring a positive message that everyone is special and that the heartbeats of children with CHD might be abnormal but create inimitably beautiful flowers. These activities tied the relationship with of children with their own heart, their families and the friendships among other children with heart disease.

HEART BLOOM Mobile Fundraiser, 2018

In 2018, for street fundraising, we developed a Heart Bloom mobile application which can be installed on a service cart, serving as a mobile ‘fundraiser’ for Dutch Heart Foundation in long-term use. The Heart Bloom application captures heartbeat data with a phone’s camera and visualizes the flower pattern interactively on the screen. The mobile Heart Bloom ‘fundraiser’ worked more ‘casually’ at a shopping center.
