OVER VIEW

COOPERATION

 

Heart Flow is an interactive installation, that could intelligently generate unique Water Marbling art pieces according to creators' heartbeat data.
It aims to reduce beginners' learning cost for Water Marbling and arouse their further interest, through a relaxing and highly relevant creating experience.

INTERACTIVE INSTALLATION DESIGN

Co-worked with my partner Ruiyao Luo

MY ROLE

Idea generation, appearance and structure design, interaction design, circuit building, digital modeling, prototyping, Arduino coding, display arrangement

DURATION

2 Months, 2018 Winter

BACKGROUND

Designing for popularizing Water Marbling, a traditional paper decoration 

craft. 

Water Marbling ( 墨流)is a kind of paper decoration craft born in China two thousand years ago. After the 12th century, it was introduced to Japan and Turkey, promoted with new names called ' Suminagashi' and ' Erub'. 

It is a floating dyeing technique. Creators use oily pigments to create beautiful patterns on the water surface by dripping, blowing and paddling. And then transfer the elegant patterns to paper for preservation.

THE CHALLENGE

How might we introduce the technique to beginners who lack artistic creation skills, and provide them with a highly relevant creating experience?

THE SOLUTION

An interactive experience that not only engagingly displays the process, but could also generate unique Water Marbling art piece according to creator's heartbeat data as a memento.

 

IDEATION

How to generate patterns under control?

Brain storm: the mechanical plans for dripping, paddling and blowing the pigments on the water surface.

Considering degrees of freedom, aesthetic factors and controllability of the drip nozzle, we chose to suspend the nozzle with three strings. Fix the spool on the axis of the stepper motor, control the moving path of the nozzle by setting the rotation angle of the stepper motor to adjust the length of the wire. When the nozzle moves to the set position, pigments in the nozzle will be blew out onto the water surface by the electric air valve.

How to interact with the installation?

The decided operation flow for audiences to create Water Marbling according to their heartbeat data.

Firstly, the creator wears the sensor module on the hand. The sensor collects his heartbeat data and transmits it to the processor through the attached Bluetooth module.

Secondly, the processor translates the heartbeat data into 3D coordinate instructions and sends them to the motor controller. Then the motor controls the nozzle to absorb pigments from bottles, move to a series of coordinate points and spray the ink onto the water surface. When the elegant patterns are generated, the creator could transfer the pattern from the water surface to paper materials.

By means of drilling, milling, lathing and grinding, wooden brackets with appropriate size are machined. And then, embed electronic components in them. Use mortise tenon structures and steel bars to fix each other together, and finally connect the wires and weld them.

In the manufacturing process, due to the change of temperature and humidity, the wood frame has inevitable natural deformation, which slightly affects the preset coordinate system size. After strict recalculation, this error is finally corrected
