The Screenless Sight Codex: Visual Transduction Technology From Signals To Perception

Author: Tristan Hash

Signals -> carriers -> transducers -> perception.

What if visual technology is best understood as a chain of transformations: encoded information moving through carriers, conversion layers, biological interfaces, and learned perception?

The map spans visual transduction technology: display physics, signal encoding, carriers, transducers, eye optics, retinal and cortical interfaces, sensory substitution, semantic cues, and memory-adjacent frontier concepts. CRTs are included where their engineering helps clarify signal, carrier, addressing, conversion, and perception, but no single display type defines the project.

Current focus: test how intermediate media can be removed, compressed, rerouted, or newly introduced. Instead of assuming that a full image must pass through every layer, the path also includes systems where trained perception becomes part of the medium: pixels become features, features become cues, and cues become usable experience through attention, motion, learning, and memory.

This is a documentation-only project. There is no Python program, no build system, and no app runtime. The repository is meant to become a structured knowledge base.

Core Question

Visual technologies can be read as transformation chains:

information source
-> encoding
-> carrier
-> transducer
-> visual or sensory interface
-> neural representation
-> learned perception
-> action, interpretation, or memory

Core question:

How can visual information be encoded, carried, converted, and learned across different physical and biological interfaces, from ordinary displays to screenless and prosthetic perception systems?

Why It Matters

Once visual experience is understood as a chain of transformations instead of only a rectangle on glass, every stage becomes a possible invention point: change the carrier, move the transducer, compress the signal, bypass a damaged layer, or invent a new perceptual language.

The path stays close to known science and engineering, then moves outward into stranger but explicit hypotheses.

Status Labels

Label Meaning
Established Standard display, optics, or visual-system science.
Research Demonstrated or actively studied in scientific or clinical research.
Prototype Plausible engineering direction with major current limitations.
Speculative Conceptual architecture with unsolved gaps, included because it may suggest useful experiments or analogies.
Frontier Far-future, fiction-forward, or not-yet-demonstrated idea kept because it can generate hypotheses and new research questions.

Speculation Policy

Speculative entries should expose the hidden design space around signals, carriers, transducers, sensory interfaces, perception, and memory.

The rule is:

keep the wild version visible
keep the evidence level visible

A good speculative entry should be bold, but explicit. It should say:

In other words, speculative labels are not stop signs. They are invitations to map the gap between idea, model, experiment, prototype, and reality.

Master Model

The broad chain is:

information
-> encoding
-> carrier
-> transducer
-> spatial or temporal addressing
-> biological interface
-> neural representation
-> perception
-> cognition
-> memory

Every arrow can be studied as its own module. Every module may have multiple possible routes.

The strongest “screenless” route may be the compressed route:

world or signal
-> feature/event/meaning extraction
-> minimal cue
-> active sensorimotor loop
-> learned perception
-> action

Here, perception is not only the endpoint. It is the medium that completes the display.

Conceptual Ladder

The ladder moves from least speculative to most speculative.

Level Name Description
1 Conventional display systems CRT, plasma, LCD, OLED, and MicroLED systems that create visible images outside the body.
2 Near-eye optics Headsets, waveguides, retinal projection, and scanned-light systems that still use normal vision.
3 Assisted retinal input Systems that enhance or replace part of the optical input while still relying on retinal processing.
4 Retinal neural prosthesis Electrical or optogenetic interfaces that stimulate retinal cells directly.
5 Visual-pathway bypass Optic nerve, LGN, or visual cortex interfaces that skip damaged earlier stages.
6 Noninvasive neuromodulation Magnetic or ultrasound approaches that may evoke percepts, but with coarse control compared with implants.
7 Learned perceptual code Systems that stop chasing natural pixels and instead teach the user a useful artificial visual language.
8 Semantic scene interface Systems that transmit labels, hazards, motion, depth, or navigation cues instead of images.
9 Cognitive cueing Systems that guide attention, recognition, or recall through ordinary perception and assistive cues.
10 Memory interface frontier Direct memory writing is not established, but the concept can be decomposed into perception, imagery, cueing, recall, and consolidation questions.

The most realistic path upward is not “build a better brain TV.” It is to reduce the amount of information that must be delivered, match the code to the biology, and let the user learn a stable interface.

00. Display Transduction Foundations

A useful visual technology can be treated as a chain: signal, carrier, conversion layer, receiver, and learned interpretation. A CRT gives one concrete route through that chain.

Stage Function
Signal input The incoming video signal encodes brightness and timing.
Electron gun A heated cathode emits electrons into a vacuum tube.
Acceleration High voltage accelerates electrons toward the screen.
Deflection Electric or magnetic fields steer the beam.
Raster scan The beam draws the image line by line.
Phosphor The screen coating glows when struck by electrons.
Persistence The phosphor glow and the eye’s temporal integration smooth the scan into an image.
Color CRT Separate red, green, and blue phosphors are addressed through beam control and mask geometry.

Key insight: the useful object is not just a screen. It is a coordinated signal-to-perception chain. A small controlled event can be addressed over time and integrated by the visual system into a stable experience.

01. Display Physics Routes

Technology Signal Route Lesson
CRT Electrical signal -> electron beam -> phosphor -> light A scanned beam can become a full image.
Plasma display Electrical signal -> gas discharge -> ultraviolet -> phosphor -> light Display chains can include gas and UV stages before visible light.
LCD Electrical signal -> liquid-crystal orientation -> polarization control -> filtered backlight Some displays modulate existing light rather than emit it.
OLED Electrical current -> organic emissive material -> light Each pixel can be a self-emitting source.
MicroLED Electrical current -> microscopic LED emitters -> light Dense direct emitters can replace scanned beams and backlights.

02. Signal Encoding

Visual information can be represented as:

The deeper question is whether a screenless interface must reproduce pixels, or whether it can transmit a more compact representation that the visual system can learn to interpret.

03. Carriers

Carrier Role Notes
Electron beam Scanned display and vacuum-tube carrier Precise in a tube, not a practical free-space biological carrier.
Visible light Normal vision and projection The safest familiar route when sent through the eye.
Infrared Optical carrier outside visible range Requires conversion or a biological/technical detector.
Ultraviolet Can excite phosphors Hazardous to tissue and not a normal vision route.
Electric current Electrode-based stimulation Requires contact or implanted interfaces for precision.
Magnetic field Can induce neural effects Noninvasive but spatially coarse compared with implants.
RF/microwave Field-based energy carrier Not a magic visual channel; would need a plausible transducer.
Ultrasound Acoustic pressure carrier Can be focused, but neural effects and safety remain research topics.
Chemical/molecular state Biological transduction route Slow compared with display refresh; relevant to optogenetics and biology.
Neural spikes Native nervous-system carrier The brain’s own signaling format, not a simple pixel bus.

04. Transducers

A phosphor screen is one familiar example of a transducer.

Transducer Converts Example
Phosphor Electron or UV excitation -> visible light CRT and plasma-style display logic.
Liquid crystal Electric field -> optical polarization change LCD.
Organic semiconductor Electric current -> photons OLED.
LED junction Electric current -> photons LED and MicroLED.
Retina Photons -> neural signals Natural vision.
Electrode Circuit signal -> local tissue stimulation Retinal or cortical prostheses.
Optogenetic cell Light -> neural activity Research and experimental prosthetic concepts.
Focused ultrasound Acoustic energy -> neural modulation Noninvasive neuromodulation research.
Magnetic coil Changing magnetic field -> induced electric field TMS and phosphene research.

05. Eye Optics

Before any retinal or neural interface, normal vision passes through optical preprocessing:

Screenless optical systems can still use the eye, for example by projecting light onto the retina, using near-eye displays, or scanning controlled light through optics. These do not remove biology; they move the display closer to the biological receiver.

06. Retina

The retina is not just a passive camera sensor. It performs early computation.

Layer Role
Rods and cones Convert light into biological signals.
Bipolar cells Relay and shape signals from photoreceptors.
Horizontal cells Support lateral interactions and contrast effects.
Amacrine cells Contribute temporal and motion-related processing.
Ganglion cells Send spike trains into the optic nerve.

Retinal prostheses try to use surviving retinal circuitry when photoreceptors or other parts of the retina have degenerated. The challenge is that stimulating one physical point does not necessarily create one clean visual pixel.

07. Visual Pathway

The standard visual route is:

retina
-> ganglion cell axons
-> optic nerve
-> optic chiasm
-> optic tract
-> lateral geniculate nucleus
-> optic radiations
-> primary visual cortex
-> higher visual areas

Each stage changes the representation. By the time visual information reaches conscious perception, it has been filtered, routed, compared, interpreted, and combined with attention and memory.

08. Neural Interface Families

Interface Status Description Main Limitation
Retinal projection Research Send controlled light to the retina without a wall screen. Eye tracking, safety, focus, field of view.
Retinal prosthesis Research Electrically stimulate retinal neurons. Low resolution and complex retinal coding.
Optogenetic retina Research Make cells light responsive and stimulate them optically. Gene delivery, brightness, safety, latency.
Optic-nerve interface Research/speculative Stimulate the visual signal cable after the retina. Fibers are densely mixed and hard to address.
LGN interface Speculative Target the thalamic visual relay. Deep target, complex relay function.
Cortical visual prosthesis Research Stimulate visual cortex to create phosphenes or patterns. Phosphenes are not clean pixels; surgery and coding are hard.
TMS phosphene interface Research Use magnetic stimulation to evoke visual percepts. Coarse targeting, variability, not image-level control.
Focused ultrasound interface Research Use acoustic energy to modulate visual cortex. Safety, precision, repeatability, and interpretation.
Sensory substitution Research Translate visual information into sound or touch. Requires learning and does not directly create normal sight.

Creative Engineering Concepts And Workarounds

These concepts are intentionally framed as research directions or design patterns, not build instructions. Their value is that they show ways around the naive “make neural pixels” problem.

Concept Plausibility Workaround Main Limit
Foveated Prosthetic Vision Prototype Put the highest information density where gaze or attention is directed and use lower-detail cues in the periphery. Requires eye tracking, fast adaptation, and careful user calibration.
Event-Camera Encoder Prototype Send only changes, motion, flashes, and edges instead of full video frames. Static scenes may lose detail unless paired with scanning or semantic cues.
Phosphene Font Research/speculative Design a small alphabet of stimulation patterns that users can reliably recognize, rather than trying to create natural images. It becomes an artificial language, not normal vision.
Personal Retinotopic Map Research Build a user-specific map from stimulation sites to perceived locations and shapes. Maps can drift over time and may change with attention, fatigue, or tissue response.
Closed-Loop Percept Calibrator Prototype The user reports what they perceive, and the system adjusts encoding until percepts become stable. Requires feedback, training, and long-term recalibration.
Hybrid Optical-Neural Overlay Speculative Use normal or remaining vision for what still works, then add artificial cues only where information is missing. Needs reliable detection of missing or degraded visual regions.
Semantic Safety Overlay Prototype Prioritize useful labels like obstacle, stairs, face, text, vehicle, door, or motion direction over photorealistic detail. Less immersive, but potentially more useful for navigation.
Depth-First Vision Prototype Encode depth, collision risk, edges, and motion before color or texture. Sacrifices visual richness for practical spatial awareness.
Attention-Guided Display Speculative Use gaze, task, or context to decide what information deserves bandwidth. Wrong attention estimates could hide important details.
Multi-Sense Redundancy Prototype Pair weak visual percepts with audio or tactile confirmation so the user does not depend on one fragile channel. Training burden and sensory overload.
Learned Visual Language Prototype Treat the interface like learning Braille or a new instrument: consistent symbols become useful through practice. It may never feel like natural sight.
Cortical Shape Tracing Research Trace shapes dynamically across cortical stimulation sites instead of flashing isolated dots. Requires stable percept mapping and invasive hardware.
Retinal Preprocessor Speculative Convert camera data into signals that mimic retinal contrast, motion, and edge processing before stimulation. Retinal codes differ by cell type and disease state.
AI Scene Compressor Prototype Use computer vision to reduce a scene into the few cues most relevant to the task. Model errors become perceptual errors.
Virtual Cane Display Prototype Encode near-field obstacles and surface changes as simple visual, audio, or tactile cues. Useful for mobility, not a replacement for full vision.
Peripheral Motion Radar Speculative Give the user coarse motion awareness around the visual field while central detail comes from another channel. Peripheral cue placement and false alarms are hard.
RF-Powered Local Transducer Speculative RF is used only to power or communicate with a local transducer; the local device performs the actual stimulation. Still requires a safe, implanted, addressable transducer.
Ultrasound-Gated Neural Pixel Speculative Ultrasound selects a region while another mechanism provides the effective stimulation signal. Coupling, targeting, safety, and coding are unresolved.
Magnetic-To-Local Conversion Speculative External magnetic fields influence a local implanted converter rather than trying to write images remotely. Requires an implant and strong safety validation.
Memory Cue Companion Prototype Use ordinary sensory prompts, labels, images, or spatial cues to support recall without pretending to write memories. Supports memory retrieval; does not create memories directly.

Workarounds By Bottleneck

Bottleneck Workaround Direction
Low resolution Use symbols, edges, motion, depth, or scene labels instead of full images.
Poor targeting Calibrate each user’s percept map and avoid assuming anatomy is a clean grid.
Limited bandwidth Use event-based sensing, foveation, compression, and task-aware filtering.
Unstable percepts Keep a closed feedback loop and update the map over time.
Slow adaptation Build a learnable visual language with consistent cues.
Safety risk Prefer external, reversible, low-power, clinically supervised designs.
Ambiguous perception Pair artificial visual cues with audio, tactile, or text feedback.
Memory interface frontier Split memory ideas into cueing, imagery, recall support, and direct-write hypotheses.

54 Associative Reconstruction Research concept Memory recall uses fragments, context, and association rather than stored pixels.
55 Dream Rehearsal Notebook Prototype Ordinary images, narration, and repetition support voluntary recall without neural writing.

10. Memory Branch

The memory branch should stay separate from visual prosthetics.

Visual prosthetics ask:

Can a device create useful visual percepts?

Memory implantation asks something much harder:

Can a device create a durable, personally integrated memory with context,
meaning, confidence, emotion, and recall behavior?

A visual percept is a present experience. A memory is a distributed, reconstructive state involving perception, attention, hippocampal systems, association, consolidation, and later recall. Display analogies become weakest here because the brain is not a video recorder.

Safety And Ethics

Any real interface with the eye, retina, optic nerve, visual cortex, or memory systems belongs under medical, scientific, and ethical oversight. This project should keep consent, safety, reversibility, and evidence quality explicit.

Speculative entries should stay focused on concepts, mechanisms, analogies, research questions, and toy models rather than device construction.
