Project at a glance
Exhibition: Accepted for installation at ISEA2026 (Dubai)
Role: Concept, system design, sensing integration, real-time visual behavior
Tools: Arduino Uno • Ultrasonic distance sensor • TouchDesigner (CHOP/DAT pipeline) • Custom typographic deformation network
Interaction: Viewer distance continuously modulates stability, oscillation, and distortion
Format: Interactive installation prototype (behavior-driven typography)
Outcome: Demonstrated perceived “temperament” and agency through continuous modulation (no figurative representation)
Overview
This project investigates how typographic form can operate as a behavioral interface rather than a static visual representation. Using real-time proximity sensing, the system continuously modulates structural stability, motion amplitude, and distortion according to the viewer’s spatial position.
Rather than depicting presence, the installation reacts to it, allowing viewers to perceive temperament through changes in visual coherence. The work therefore examines whether perceived agency can emerge from continuous visual modulation alone, without figurative representation or explicit interaction controls.
Research Question
Can abstract typographic form communicate awareness of human presence through behavioral change rather than representational imagery?
More specifically, how does distance-based modulation of visual stability influence a viewer’s perception of agency, sensitivity, and spatial negotiation within an interactive system?
Conceptual Framework
The project draws on the theory of proxemics introduced by the anthropologist Edward T. Hall, who described how physical distance structures social behavior and perception. While proxemics traditionally applies to human interaction, this system extends the concept to human–artifact relationships.
The work also engages with embodied interaction theory, which argues that cognition emerges through physical engagement with space rather than abstract symbolic input. Instead of clicking or touching an interface, the participant’s body becomes the parameter.
By allowing typography — historically a fixed communicative structure — to destabilize in response to proximity, the system explores how visual form can simulate behavioral traits such as agitation, calmness, or defensiveness without relying on figurative imagery.
The viewer is not observing a screen; they are negotiating territory with a responsive spatial entity.
System Architecture
The installation operates as a behavioral pipeline:
Input → Interpretation → Expression
- Distance is measured continuously using an ultrasonic sensor.
- Sensor data is normalized into a 0–1 behavioral range.
- This value modulates deformation intensity, oscillation frequency, and structural coherence within the typographic system.
- State transitions can be triggered manually through a physical keypad interface.
The visual output does not replay pre-authored animation; it emerges from parameterized behavioral rules.



Technical Implementation
The system is composed of two interconnected layers: a sensing environment and a behavioral visual engine.
Physical Layer
An ultrasonic distance sensor continuously measures the viewer’s proximity.
An Arduino Uno microcontroller streams this data to the computer through serial communication.
A physical keypad provides discrete state changes, allowing participants to manually alter behavioral modes.
Computational Layer
Within TouchDesigner, incoming values are parsed and normalized into a continuous behavioral parameter space.
Distance values modulate deformation strength, oscillation frequency, and typographic coherence.
Rather than triggering predefined animations, the system recalculates form in real time according to rule-based transformations.
The visual output therefore emerges from conditions, not timelines.
Behavioral States
The typography operates as a reactive entity whose structure reorganizes according to spatial proximity:
Distant Presence
Forms remain unstable and continuously in motion. Oscillation and deformation persist, suggesting a searching or unfocused state.
Approach
Motion begins to dampen as the viewer enters the sensing field. The system reduces variability, appearing to “attend” to the presence.
Close Proximity
The structure stabilizes and becomes legible. Movement diminishes and coherence increases, producing a calm and resolved state.
Interaction Trigger
Manual input produces abrupt visual flashes and state transitions, reinforcing the perception of responsiveness.
The behavior therefore shifts from ambient activity to focused stability, creating the impression of attention rather than agitation.



Observations
During interaction, participants rarely remained static.
Viewers approached cautiously, then stepped back once instability increased. Many attempted to locate a “safe distance” where the typography appeared calm but responsive.
Instead of treating the installation as a display, participants negotiated space with it — testing boundaries, provoking reactions, and adjusting their position accordingly.
The system therefore shifted behavior from observation to spatial dialogue.
Evaluation notes (informal)
Setting: Studio prototype test
Participants: 12 viewers (informal observation)
Method: Open exploration with proximity-based response; brief post-interaction prompts
What was documented: Interaction video clips + observational notes on approach/retreat behavior and “safe distance” searching
Interpretation
The installation revealed that viewers did not treat the typography as an image but as a responsive presence. Participants rarely attempted to understand the system technically; instead, they attempted to negotiate with it. Movement became tentative, exploratory, and reversible, suggesting that the visual response was perceived as sensitivity rather than animation.
This indicates that behavioral variability alone can produce perceived agency without anthropomorphic representation. The system therefore operates less as an interface and more as a spatial actor whose “temperament” emerges from continuous modulation rather than discrete interaction events.
The findings suggest that in interactive environments, responsiveness may be communicated more effectively through stability and resistance than through explicit feedback cues such as buttons, cursors, or prompts.
Key contribution(s)
- Demonstrates typography operating as a responsive behavioral interface rather than a fixed visual carrier.
- Shows that continuous modulation — not discrete triggers — can generate perceived agency.
- Extends proxemics from human–human interaction to human–artifact spatial negotiation.
Significance
The project proposes typography as an interface rather than a surface.
Meaning is communicated not through symbolic representation but through behavioral response.
By coupling spatial sensing with visual instability, the work demonstrates how graphic form can express sensitivity, resistance, and presence without anthropomorphic imagery.
This suggests alternative models for interactive environments where communication emerges from spatial behavior instead of explicit controls.
Future Directions
Future iterations will explore multi-user interaction fields, allowing competing proximities to produce collective behavioral states.
Additional sensing modalities may introduce velocity and gesture recognition, enabling the system to respond to movement patterns rather than distance alone.
Scaling the framework architecturally could transform responsive graphics into environmental communication systems within public or exhibition spaces.
