#Final Project Proposal
Assignments: Propose a final project masterpiece that integrates the range of units covered. Your project should incorporate: 1. 2D and 3D design 2. Additive and subtractive fabrication processes 3. Electronics design and production 4. Microcontroller interfacing and programming 5. System integration and packaging Where possible, you should make rather than buy the parts of your project. Projects can be separate or joint, but need to show individual mastery of the skills, and be independently operable.Published on: Apr 01, 2020
In this proposal, presents one work, “Breath of Flora” —— an interactive sound and light mechanical flower. Infrared sensors and sound detection sensors are used in the artwork as the main technique to interact with people. The work adopts “Listening” as the concept and is going to be displayed in the oldest and longest functioning mental hospital in Finland —— Lapinlahti Hospital around summer in 2020.
Art Education, Physical Perception, Kinetic Sculpture, Distance and Sound Detection, Interactive Installation
The artwork will be installed on the corridor wall in the hospital as a decoration to intrigue passersby to stop and interact with it. Motors, gears, metal sheets, and microcontrollers are implemented to build the work into a mechanism in a shape of a flower for the purpose of echoing to one of the most essential medical treatments to patients —— the outside large blooming garden. Since natural surrounding plays an advantageous role in the cure of patients, it was taken into account while constructing the hospital, which was in fact unconventional in those days.
In the dim quiet passage full of kinetic flowers, these blossoms act as if they were transformed from consciousness of the past sufferers living with perception, leading audiences to listen and feel the patients' apprehension and belongingness deep inside their hearts. By detecting the distance between pedestrians and the installation with an infrared sensor, the inner microcontroller sends a signal to trigger the flower to blossom and light up LEDs hiding inside petals at the breathing rate. On the other hand, the script of a soliloquizing speaker placed inside the ovary of the flower installation correlates with the volume of the sound in the space which is observed by a sound detection sensor.
I found a final project about the mechanical blooming flower from the 2016 fab academy archive. The author used a servo as its output device, 3D printed components and poplar wood to construct the hardware parts. For the interaction, he adopted a photoresistor as its sensor which requires close/touchable detection.
The proposal mainly focuses on how to augment new media art to intervene in our daily life with the approach of enhancing the interaction between viewers and artworks. Most art pieces in domestic hospitals such as paintings, sculptures and calligraphy are all in the static state and passively waiting for people to appreciate and discover their notions. “Breath of Flora” —— an interactive sound and light mechanical flower contributes a whole new experience of art appreciation in the following aspects:

According to the material table above, the total amount is around €500 for 5 units (i.e., €100 per flower).
The “Breath of Flora” —— interactive sound and light mechanical flowers will be divided into these parts during its development:
Additive and subtractive fabrication processes
3D printers such as Ultimaker 2+ Extended will be used as tools for the addictive fabrication process to manufacture its 3D components designed in Fusion 360.
A laser cutter or a CNC milling machine will be adopted to subtractively fabricate a wooden box for packaging all the electrical components.
Microcontroller interfacing and programming
The megaTinyCore Arduino library will be used for programming the board to trigger a stepper motor to open the flower, light up the LEDs installed inside its ovary as well as play pre-recorded human voice sound files saved in a SD card.
After finishing making the systems above, there are some other processes left:
So far there are some questions I might need to think about at the moment:
For my own evaluation, the first flower prototype should follow its program to interact with audiences in real-time without any delay or shutdown. It is also important to me to get the feedback about whether or not the interaction is intuitive without any guidance from the people who play with it.
