Module 06
Tools
The interactive learning layer. Tools turn the atlas from a reference into a study aid — searchable terminology, printable compilations, spaced-review quizzes, clinical cases, pattern training, and a personal progress dashboard. All progress is stored locally in your browser; nothing is sent to a server.
Available now
Two tools are live. Use them as you work through the chapters.
Glossary
Searchable terminology reference with bookmarking and chapter back-references
Forty-two canonical terms used across the atlas, each with a one-or-two-sentence definition, aliases, see-also cross-links, and back-references to the chapter section where the term is developed. Search the term name, aliases, or definition body. Bookmark terms to revisit; the bookmarks set is persisted locally and surfaces on the Progress dashboard.
For
Anyone reading any chapter who encounters unfamiliar vocabulary
Print edition
Twelve modules compiled into one document for PDF export or printing
Cover, table of contents, and every module rendered in pedagogical order, with page-break-before declarations between chapters. All three reader levels appear in print regardless of the sidebar level selector. Designed for browser 'Save as PDF' / 'Print' workflow — A4 geometry with 16-18 mm margins.
For
Clinicians wanting an offline reference, trainees printing for a study group
Self-assessment quiz
Twenty-eight single-best-answer questions across three study modes
Browse mode with combinable level (Foundation / Trainee / Clinician) and topic filters. Spaced-review mode offering two scheduling strategies: a five-box Leitner scheduler (10 min / 1 d / 3 d / 7 d / 21 d intervals) and a three-in-a-row streak scheduler with miss-reset. Timed mode: 10 random questions in 5 minutes, mid-round answers hidden until finish, personal best tracked locally. Every explanation deep-links back to the relevant chapter section so the reader can revisit the source material.
For
Trainees preparing for vestibular-themed examinations; clinicians refreshing
Clinical cases
Hand-authored case vignettes with diagnostic reasoning and rationale
Eight clinical cases covering the major DVA-relevant disease patterns — ototoxicity-induced bilateral vestibulopathy, vestibular neuritis, Ménière's disease with caloric-vHIT dissociation, vestibular schwannoma, posterior circulation stroke mimicking neuritis, presbyvestibulopathy at the BVP boundary, vestibular migraine with normal vestibular testing, and BVP rehabilitation tracking. Each case carries a vignette, audiogram where relevant, DVA-and-vHIT findings, a single-best-answer diagnostic question with per-option rationale, a teaching point, and references. Per-case completion tracked locally. Filterable by reader level.
For
Trainees applying chapter content to integrated clinical scenarios
Comparison tool
Side-by-side comparison of disease DVA signatures and test-battery patterns
Two-dropdown picker covering eleven disease and normal signatures. Overlay mode shows both signature traces on a shared four-axis radial chart with the 0.2 logMAR action threshold highlighted. Panels-vs-normal mode shows two side-by-side comparisons each against the normal reference profile. Per-signature description card below the figure with read-more link to the relevant chapter. Useful for revising differential-diagnosis nuance between similar presentations (Ménière's vs vestibular migraine; bilateral vestibulopathy vs presbyvestibulopathy; vestibular neuritis vs vestibular schwannoma).
For
Trainees reviewing differential diagnosis; clinicians comparing patterns at point of care
Pattern recognition trainer
Infinite random cases with graded feedback against archetype truth sets
Random selection from eight DVA disease archetypes, with lightly-jittered exemplars so no two rounds are identical. Seven-finding vocabulary specific to DVA: loss present, horizontal directional asymmetry, vertical directional asymmetry, symmetric bilateral, severe loss, horizontal with preserved vertical, progressive trajectory. Tick the findings you observe, click Reveal, get graded against the archetype's truth set with per-finding correct / missed / over-called breakdown. Per-user statistics persisted locally — rounds played, perfect calls, cumulative accuracy. Stats surface on the Progress dashboard.
For
Trainees building pattern-recognition fluency; useful in short repeated practice bursts
Progress dashboard
All locally-stored progress and preferences in one view
Top metric strip with chapters visited, active time on atlas, cases completed, quiz cards due, and glossary bookmarks. Spaced-review deck breakdowns for both Leitner (per-box counts + intervals) and Streak (fresh / 1-of-3 / 2-of-3 / graduated) schedulers. Timed-mode personal best. Bookmarked glossary terms with click-through. Per-chapter dwell time and visit count, sorted by total time. Page-visibility-aware tracker that pauses when the tab is hidden. Confirmation-gated reset that preserves theme and content-level preferences.
For
Self-directed learners wanting visibility into their atlas usage
Coming next
These tools are scaffolded into the navigation and will be enabled as they ship. The order below reflects the planned build sequence — the quiz and cases are the highest-priority next features.
How the Tools fit together
The chapters teach the test, its physiology, its technique, and its disease signatures. The Tools layer is where the reader applies that knowledge — identifies the pattern, defends the diagnosis, justifies the management. A trainee preparing for a postgraduate examination might use the Quiz daily for spaced review, work through the Clinical cases on weekends, and use the Comparison tool when revising differential diagnosis. The Progress dashboard is the feedback loop — what you've covered, what you've missed, where to focus next.
The atlas is deliberately self-contained: no server-side state, no authentication, no per-user accounts. Everything works offline once the static files have loaded. This is a design choice, not a limitation — vestibular medicine often needs a quiet, focused, unobserved space to learn in.
