WaterDropletPrint

The installation WaterDropletPrint is a public artwork located in Feng-Chia University, Taichung, Taiwan. Based on the principle of reflection of water, it is a dynamic interactive installation which can blur the transparency of the vision of people.
Through the intelligent water valve system, the water droplets can be controlled to stay in the iron mesh. With the passage of time and the force of the wind, the water droplets will gather to different shapes, which corresponds to the change of the four seasons. This can slightly reveal the change of landscape with the mark of time. Moreover, the visitors can leave any shape of water droplets in the iron mesh by drawing on the screen of their mobile phones. This enables the connection of the visitors' natural and temporal shared imaginations and memories.

WaterDropletPrint is a piece who is 15 m x 1.5 m x 3.25 m big and made from 12 pieces of stainless steel mesh, 6 water solenoid valves, a 6-bay 2-axis track and a 12-axis track control system.
The system flow of the device can be divided into seven categories, namely creation, reception, translation, transmission, execution, and presentation.
(1) Creation: There are two types of creation section. The first one is to study the uncertainty, transparency and time passing characteristics of the water, in order to figure out the pattern with the best effect to perform the titration action. The second to control the whole mechanism with the help of smart mobile phones, which can allow the people to program their own images on the Internet. The image will be presented in the form of drops of water on top of the work according to the user’s wish. And all the related signals will be transmitted via wi-fi.
(2) Receiving: The signal from the creation area will be received by the computer. And after the receiving of the signals, they will be transcripted immediately according to the program stored in the computer, which was compiled by us.
(3) Transcription: C# will be used to compile the program according to the requirement of the device. Through the graphics exported from the creation area, the speed and acceleration required for the motor and as well as the distance that the motor needs to travel and the I/0 control code will be calculated and translated.
(4) Sending: According to the code from the transcription area, the stepper motor will give different forward commands, and with the I/0 switch. The sending section is responsible for sending all the signals for the show.
(5) Execution: the stepping motor will receive the signal from the sending area and drive the slide. With the usage of the I/0 signal, the switch of the water solenoid valve above the slide will be controlled, so that the water drops can be titrated. This enables the water drops draw out the graphics presented in the creation section.
(6) The presentation: Using the changes of these graphics, weather and environment changes and the passage of time, the drops of water will be fleetingly presented on the iron mesh. These drops of water make people's eyes can feel the environment changes in the atmosphere, which connects the information of the environment, weather, time, drops of water and other information. This novel technology can enable people to redefine the spatial atmosphere of this site with the usage of the device.
