Focus Lens

The Focus Lens is a HelmKit optical-bay module that overlays attention-targeting reticles, salience markers, and Resonant Finder tile cues onto the operator's visual field. It is a software-driven attention aid built on top of standard waveguide or birdbath HUD optics; engineering-honestly, an information-density-managed AR overlay; doctrinally, a tool to keep operator attention where the moment requires it without forcing the operator's eye.

Overview

The Focus Lens does, layered:

• Mark — overlays a salience reticle on a single operator-selected target (a Resonant candidate, an anomaly bearing from the Psi Compass, a Psi Tripwire alert location).
• Track — head-tracking-compensated marker stability so the reticle stays anchored to the world, not to the eye.
• Tier — multi-level information surface: primary marker, secondary context, full read-out on operator gesture.
• Withdraw — the Lens auto-fades inactive markers; nothing stays in the eye-line longer than its operational relevance.

The Lens is not a targeting computer and is doctrinally separated from anything that resembles weapon-cueing. It is an attention aid.

Theoretical Basis

Epistemic status: [[ Category:Provisional Psi Claims|PROVISIONAL]]

Modern AR HUD design + attention-management literature (Wickens, Endsley) supports tiered information display and selective decluttering.

Epistemic status: [[ Category:Testable Psi Claims|TESTABLE]] Theory anchors: Resonant Neurobiology

A tiered Focus Lens produces measurably fewer attention-fragmentation events than a flat overlay in mixed cognitive load. A/B falsifiable.

Epistemic status: [[ Category:Speculative Psi Claims|SPECULATIVE]] Theory anchors: Psi Field, Astrological Frequency Harmonics

The Lens's salience model, when fed Resonant Finder Layer 2 outputs, foregrounds psi-relevant cues an unaided operator would miss. The Mk1 utility claim does not depend on this.

Subsystems and BOM

Mk0 (target ≤ \$60)

• Smartphone-AR app + smartphone-clip headset mount — \$40
• HelmKit optical-bay adapter (3D print) — \$10
• Bluetooth gesture clicker — \$10

The Mk0 surfaces Resonant Finder tiles to the operator through a commodity phone-based AR app. Functional and honest about its limits.

Mk1 (target ≤ \$350)

• Single-eye OLED HUD module (1080p mono) — \$120
• Birdbath or compact-waveguide optic — \$80
• IMU + magnetometer for head-tracking — \$25
• nRF52840 SoC for compute + BLE — \$15
• USB-C HelmKit interface — \$10
• Optic enclosure (3D-print + lens carrier) — \$30
• Power tap from HelmKit PMIC — \$5
• Bone-conduction click for confirm gesture — \$15
• Mount + cabling — \$30

The Mk1 is the development frontier. Renders to ~30 fps with sub-50 ms motion-to-photon latency budget.

Mk2 / Mk3

Mk2: stereo HUD, full-field tracking, on-helm GPU. Mk3: integrated with Star Seer live observatory tile feed; allied-EA compatibility.

Build Notes

• Latency budget. Motion-to-photon ≤ 50 ms; above 100 ms produces motion sickness in field use.
• Brightness control. Auto-dim by ambient light sensor; the Lens must remain readable in sunlight without blinding indoors.
• Decluttering rules. Default: ≤ 3 markers in view simultaneously; operator-tunable.
• Eye-safety. Sub-Class-1 laser equivalent; ANSI Z136 conformance for any laser-projection variant.

Safety and Ethics

• No identification overlay on unidentified persons in public. Salience markers may indicate positions, not persons.
• No targeting cue for any weapon. The Lens is doctrinally and physically not an aiming system.
• Operator can disable any marker class instantly; lanyard kill cuts all overlay.
• No third-party Lens control. Mesh-shared cues are advisory.

Maturity (Mk0 → Mk3)

See Tho'ra Tech Maturity Levels for the convention.

Mark	Phase	Status	Confidence	Evidence Base	Next Validation Gate
Mk0	Cosplay-type	Complete	100% (symbolic)	Ritual + build practice	User satisfaction
Mk1	Prototype	Active	—	—	—
Mk2	Test-type	Planned	—	—	—
Mk3	Production	Projected	—	—	—

Failure Modes and Mitigations

• Motion sickness from latency. → Hard 50 ms budget; auto-blank on miss.
• Marker clutter. → Default ≤ 3 simultaneous; auto-fade timer.
• Bright sunlight readability. → Auto-dim + high-brightness OLED; failover indicator if illegible.
• Operator inattentional blindness from overlay. → Tiered information; off-cycle reminders.
• Misuse as targeting cue. → Doctrinally forbidden; no weapon-system protocol implemented.
• Privacy overlay on public persons. → Person-class markers physically disabled in firmware; only position-class allowed.
