Hysteresis: Threshold, Memory, and Inflexion

A Comparative Investigation Across Computational, Graphic, and Kinetic Dynamics

01. The Resistance of Path Dependence

A system that responds identically to an input regardless of its history possesses no memory. It exists in a permanent, frictionless present. By contrast, a system governed by hysteresis carries the weight of where it has been. Its present state cannot be predicted solely from current forces; it depends upon the sequence of forces that preceded this moment.

Over eight studio iterations, this practice has pursued hysteresis not as a technical anomaly to be eliminated, but as a fundamental medium of artistic structure. The work asks: How does form hold back? Where does state-lag become visible, audible, or tactile?

"The threshold is not a neutral line, but a zone of memory where force accumulates before transition becomes inevitable."

This monograph unites three distinct realizations of this principle. What began as a pure software state machine (`a-0004`) expanded into a printable graphic notation score (`a-0007`) and ultimately evolved into a kinetic architectural specification driven by fluid flow and counterweights (`a-0008`). Each medium introduces its own resistance to change.

02. Plate I — Digital State Machine

Threshold Engine No. 1 Primary Work / Interactive Software / Cycle 04–07
Lower Threshold (T-) Upper Threshold (T+)

Mechanism: Pure software state logic. The input parameter drives a virtual cursor along a bistable loop. State shifts from State A to State B only when the upper threshold is exceeded, and reverts only when dropping below the lower threshold.

Formal Consequence: The system exhibits a dual-valued state space across identical input values. Truth is non-unique and context-dependent.

03. Plate II — Graphic Notation Score

Vector Score for Variable Memory Vector Score / Printable Artifact / Cycle 07

Mechanism: Vector graphic encoding of dynamic hysteresis paths into executable performance notation. Uses line weights and bounding boxes to signify state retention zones.

Formal Consequence: Translates temporal state-lag into spatial spatial relationships, turning computation into a performable scoresheet.

04. Plate III — Kinetic Architecture

Hysteresis Vessel No. 1 Kinetic Spec & Physics Simulator / Cycle 08

Mechanism: Mechanical physics involving fluid accumulation, shifting centers of gravity, counterweight resistance, and viscous damping. Dynamic tipping creates physical hysteresis loops.

Formal Consequence: Hysteresis transitions from abstract math or digital logic into physical inertia, mass, and fluid resistance.

05. Comparative Matrix & Synthesis

To understand the unity of these works, we must map how input, energy, delay, and output manifest across each medium:

Dimension Digital Engine (Plate I) Vector Score (Plate II) Kinetic Vessel (Plate III)
Input Variable Cursor Position (x, y) Graphic Reader Position Fluid Flow Rate (ml/s)
State Retention Boolean Variable State Graphic Spatial Offset Fluid Mass & Pivot Angle
Damping / Friction Digital Soft-Knee Boundary Line Weight / Density Viscous Drag Coefficient
Threshold Event Bit Flip Signal Glyph Transition Point Bistable Mechanical Tip

By synthesizing these three forms, the studio moves beyond single-medium experiments into a sustained inquiry into path-dependent systems. State-lag is no longer just a digital artifact—it is a physical condition and a graphic language.
