Final Project Concept: Intelligent Interactive Environments
1. Design Sketches & Concepts
🛋️ Functional Interactive Chair
Inspiration: My inspiration came from sleep-assisting beds at an elderly care product expo. These beds help users fall asleep through gentle rhythmic shaking. Combined with the right temperature, music, and lighting, the experience is highly effective.
Core Features: * Rhythmic Support: Integrated airbags at unsupported joints to provide gentle up-and-down movements. * Multisensory Therapy: A combination of temperature control and ambient music to address sleep issues. * Evolution: While I have designed chairs before, this version focuses on functional interaction rather than just static form.
🧢 Light-blocking Hood (Sleep Series Extension)
This is a portable extension of the sleep series designed for rest on the go. * Zero-Interface Interaction: Designed for simplicity and portability. * Smart Inflation: Automatically inflates to provide neck support once activated. * Intelligent Wake-up: Gradually wakes the user based on external environmental conditions or a preset timer.
💿 Intelligent Rhythmic Light Disc Seats
Interactive Logic: * Autonomous Mode: When unoccupied, the seats move slowly with a "breathing" light pattern, interacting autonomously within the space. * Human-Centric Interaction: When a presence is detected, the seat utilizes sensors to track gravity, heart rate, and breathing. * Dynamic Response: These vital signals reshape the seat’s movement trajectory and light patterns in real-time, creating a poetic dialogue between the human body and the algorithm.
but for this idea i have new thinking:
🌙 Ambient Nodes
A spatial interface where connection is felt, not defined
🧾 Project Description
A quiet system of spatial nodes, disguised as familiar objects, that respond to the presence of the body.
As one sits, light begins to breathe—slowly, almost imperceptibly—expanding across the surface and into the surrounding space.
When multiple bodies share the space, their rhythms overlap, synchronize, and interfere, forming connections that are neither fully controlled nor entirely understood.
The project does not aim to create direct interaction, but to reveal how connection emerges through proximity, time, and shared presence.

| Top Layer | Stretch fabric / knit textile | Defines outer surface and touch | Soft, warm, non-technical appearance | Should remain visually neutral and hide internal structure |
| Diffusion Layer | Foam / silicone / diffuser sheet | Spreads and softens light evenly | Smooth, ambient glow without hotspots | Critical layer — determines overall light quality |
| Light Layer | LED strip (WS2812) | Generates dynamic light behavior | Enables breathing, flow, and interaction patterns | Must not be directly visible; positioned beneath diffusion |

Interaction & System Logic
Behavioral States * Idle: Slow breathing light representing presence. * Active: Light expands and intensifies upon physical contact. * Sustained: Stable rhythm maintained during continuous touch. * Proximity: Nodes synchronize patterns based on distance and duration of closeness.
Logic Factors * Distance: Defines the intensity of the inter-node connection. * Time: Defines the depth and stability of the emergent bond.
Bio-modulation (Optional) * Heart rate adjusts breathing speed; variability introduces subtle instability. * Note: Modulation only, no direct mapping.
Expression System
- Breathing: Slow, rhythmic fade in and out.
- Flow: Light movement across the surface.
- Transmission: Light patterns transferring from node to node.
- Interference: Overlapping patterns causing visual disruption.
- Subtle Movement: Optional 3–8 mm slow physical deformation. Using micro servo.
Development Roadmap
| Phase | Requirement | Features |
|---|---|---|
| Minimum Viable Prototype | Functional Prototype | 2 Nodes, pressure sensing, basic breathing light |
| Evaluation | Perception Goals | Functional sensing, emergent connection, sense of aliveness |
| Future Development | System Expansion | More nodes, mobility, sound layers, and bio-sensing |
Final Statement
The project is not about interaction, but about how connection emerges quietly through presence, time, and proximity.
🎨 Research: Light Art & Perception
The development of contemporary light art is deeply influenced by the Light and Space Movement, placing a core emphasis on perceptual experience.
1. James Turrell
Based on perceptual psychology, Turrell treats light as a physical, volumetric substance. * Representative Work: Ganzfeld Series * Concept: Eliminates the sense of depth through uniform colored light, allowing the audience to experience “seeing oneself seeing”.
2. Olafur Eliasson
Eliasson specializes in simulating natural phenomena to investigate the relationship between humans and their environment. * Representative Work: The Weather Project * Concept: Created a gigantic indoor sun at Tate Modern using monochromatic lights and haze.
3. TeamLab
An internationally acclaimed digital art collective integrating lighting, projection, and sensors. * Representative Work: The Infinite Crystal Universe * Concept: Employs tens of thousands of LED nodes to alter patterns in real-time based on audience movement.
4. Dan Flavin
A pioneer of light art who defined architectural boundaries using industrial fluorescent tubes. * Key Focus: Using standard industrial materials to transform the perception of architectural space.
