DESIGNING INTERACTIONS: VISUALIZING DATA

Workshop 1 Geurilla Prototyping I

Following the tutorial's instructions, we cut out cardboard pieces of identical dimensions and marked the edges for cutting or folding (to avoid trimming sections that needed to remain intact, areas requiring removal were marked with crosses). We trimmed the edges as instructed, leaving the cut-out insert intact. Fold the cardboard along the marked lines to curve and insert it, forming the front tabletop to complete the assembly. The finished mobile phone stand in operation. Improved version – optimising stability by simply extending the side supporting the phone, shifting the centre of gravity rearwards. More importantly, this slightly reclined angle allows users to sit more comfortably when viewing the screen at a desk.

Workshop 2 Geurilla Prototyping II

Draft 1: The lunar model hovers above the base, with light intensity control buttons on the surface. The Arduino and breadboard are housed in two layers within the structure. Draft 2: The lunar model remains elevated, but this time the Arduino and breadboard are positioned parallel within the device. A drive shaft synchronises the user's movements with the Arduino's receiver knob. Draft 3: Completely separates the lunar model from the control unit, connected solely by wires for data transmission. Initial prototype. Utilises Draft 2 (with open sides to reveal internal structure and facilitate debugging). Top view of initial prototype. The bulb and hollow sphere simulate the lunar model.

Activity 1: My Research

Initial debugging of basic Arduino and breadboard connections – a foundational attempt. Material testing – applying acrylic paint to transparent PE material to determine suitability for later painting the moon model's surface. Drive shaft model construction. The knob's interior features a fixed shaft for inserting the board. Holes drilled in the board ensure the knob rotates freely. Additionally, a positioning device beneath the board secures the fixed shaft to prevent the knob detaching from the board. During debugging and research, it became apparent that the Arduino knob could not precisely control specific numerical values. Consequently, we realised implementing a ‘calendar’ function was impractical—yet the phases of the moon remain constant. Thus, we decided to replicate only the eight distinct lunar phases, focusing on capturing this cyclical pattern. A 3D lunar model was selected to serve as a reference for particle system movement in subsequent production stages.

Activity 2: My Research

Preparing to build the prototype, we first sketched a basic circuit diagram. Following a YouTube tutorial, we debugged the circuit to make the LED light up—starting with the Arduino. Connected to the breadboard. Still debugging, troubleshooting why the bulb wouldn't illuminate. The successful version. The bulb is now lit. Now the knob can be turned to control the LED's brightness (though the effect is subtle).

Additional Research or Workshops

Immersive Art Exhibitions Reframe What People Expect from Technology explains that immersive art installations are shifting audience expectations—they no longer just observe, they participate, interact, and even influence. Our project’s interface (knob + light sensor + particle moon) fits this model: actions change the visual world. The physical housing and sensor interactions bring tangible interface into installation space rather than a screen environment. The transition from chaos to moon form, and the reflection of user gestures, aligns with immersive installation behavior: the system responds to the user and the environment. “Discover the must‑see exhibitions for autumn 2022” reviews immersive digital‑sculptural installation combining colour, projection, and spatial form. Highlights how exhibition designers use projected visuals interwoven with physical objects to create “micro experiences”. We may use of physical structure (moon ornament / paperboard shell) that becomes the anchor for projection or particle visuals. And think about spatial placement and how the housing invites approach and interaction—not just a screen! “Culture Guide Autumn 2023 – immersive, interactive displays” examines interactive, multisensory installation work that engages audiences through touch, sound, and movement. Emphasises the shift from “look at” to “participate in”. We might make the physical interface inviting: knob and light sensor should feel like an instrument. And we can consider ambient cues (sound, subtle vibration, glow) that elevate the interface beyond simple control to sensory experience. Arduino Uno for TouchDesigner and Immersive Experiences—I explored a range of artist projects where Arduino sensors trigger visual changes and LED responses in TouchDesigner. I can use these examples as inspiration for mapping my own hardware inputs to visual behaviours — especially for creating expressive reactions in my moon particles. I have located reference material to preview the anticipated lunar phase transition effect at this stage—in the form of a continuously moving particle system.

Project 2

Project 2 Prototype

1. Hardware (Circuit + Arduino) Prototype
· Added colour and texture to the “moon” to better match the theme
· Removed the light bulb element to avoid confusion
· Redesigned the container to appear less bulky
· Used Illustrator and laser cutting for constructing the container
· Integrated light sensor to capture LED data for TouchDesigner

2. Software (TouchDesigner)
· Created dynamic change to the moon depending on user inputs
· Provided an intuitive and engaging experience for users to interact with the UI
