45. Neural Scanning Interface
- Status: Frontier
- Interface point: Retina, optic nerve, or visual cortex
- Carrier: Depends on future interface
- Transducer: Retinal, cortical, optical, acoustic, magnetic, or local converter
- Encoding style: Scanned stimulus over time
- Addressing method: Raster, spiral, saccade-linked, or feature-trace scanning
- Expected percept: A temporally built artificial percept
- Related modules: Display Transduction Foundations, Creative Engineering
Summary
This scenario takes temporal scanning from display history and pushes it into a
frontier biological or prosthetic context. Instead of forming a whole image at
once, it scans a controlled stimulus across a target and relies on perception to
integrate the sequence.

Scanning Patterns
| Pattern |
Possible Use |
| Raster |
Line-by-line temporal update. |
| Spiral |
Fovea-first or center-out cueing. |
| Edge trace |
Draw object outlines only. |
| Symbol trace |
Draw glyphs, arrows, or warning icons. |
| Motion trace |
Emphasize movement direction. |
| Attention trace |
Scan only the task-relevant region. |
Expansion Ideas
- Compare raster scanning with shape tracing.
- Use event-based input so only changed regions are scanned.
- Build a software simulator for scanned phosphene fields.
- Design a phosphene font optimized for scanning.
- Use gaze to steer the scan path.
Research Questions
- What scan speed feels continuous?
- Does temporal tracing improve form recognition?
- Is raster scanning wasteful compared with feature tracing?
- Can the brain learn an artificial scan grammar?
