65 terms
- AI Swing ReportBeginnerThe AI Swing Report is the comprehensive analysis document SwingVantage generates after processing your video, combining the deterministic engine's findings with optional AI-enhanced commentary into a single, prioritized report.
- AI-Enhanced AnalysisBeginnerAI-Enhanced Analysis is the optional second layer of SwingVantage's analysis pipeline — added on top of the deterministic heuristic result — that uses an AI language model to generate contextual explanation, drill language, and coaching narrative.
- Analysis JobIntermediateAn Analysis Job is the traceable processing record created each time you submit a video or session for analysis — it tracks status (queued, running, complete, failed), the inputs used, and the outputs produced.
- BalanceBeginnerBalance in a swing context is the ability to maintain a stable base and controlled center of mass through the full motion — from setup through the end of the follow-through.
- Baseline MeasurementBeginnerA baseline measurement is the first recorded data point for a metric, captured before training begins, that all future improvement is measured against.
- BenchmarkIntermediateA benchmark is a reference value that defines acceptable or optimal performance for a metric; SwingVantage score outputs use one fixed pro grading standard.
- Blocked PracticeIntermediateBlocked practice is repeating the same skill or shot in the same conditions many times in a row — effective for initial skill acquisition but less effective for long-term retention than varied practice.
- Camera Angle QualityBeginnerCamera angle quality describes how well the recording position allows the system to see the relevant joints and movement plane — the single biggest controllable factor in analysis accuracy.
- Confidence ScoreBeginnerA confidence score is a 0–100 calibration of how much to trust a finding, scaled by sample size, shot-to-shot consistency, and how complete your inputs were.
- Consistency ScoreIntermediateA consistency score measures how tightly grouped your metrics are across multiple swings — low variance produces a high score. This is because consistency is often more valuable than peak performance.
- Data Source LabelBeginnerA Data Source Label is the badge shown alongside every metric in SwingVantage that identifies where that data came from — Measured, Estimated, AI Interpreted, Placeholder, or Real — so you always know how to weight it.
- Deliberate PracticeIntermediateDeliberate practice is focused, feedback-rich work on a specific, diagnosed weakness — distinct from mere repetition or play — that produces faster skill gains per hour of effort.
- Deterministic IntelligenceBeginnerDeterministic intelligence is analysis that follows explicit, written rules, so the same inputs always produce the same answer and you can trace exactly why.
- Diagnostic ConfidenceBeginnerDiagnostic confidence is how certain SwingVantage is about a given finding, based on how much data was available and how reliably the pattern appears.
- Drill ProgressionIntermediateA drill progression is an ordered sequence of practice exercises that move from isolated, slow, and controlled movements toward full-speed, contextual performance — matching how motor learning actually works.
- Estimated ValueBeginnerAn estimated value is a number derived from observable cues and encoded rules rather than from direct sensor measurement. A confident, grounded inference that is never presented as a measured fact.
- Evidence LabelBeginnerAn evidence label separates what SwingVantage measured (a sensor or launch-monitor number) from what it estimated (an inferred likely pattern). As a result, an estimate is never presented as a lab measurement.
- Frame RateIntermediateFrame rate (frames per second, fps) is how many individual images your camera captures each second — higher frame rates freeze fast motion better and produce more reliable pose tracking.
- Ground Reaction ForceAdvancedGround Reaction Force (GRF) is the force the ground exerts back against an athlete's feet. The foundational energy input for the kinematic chain in every swing sport.
- Heuristic AnalysisBeginnerHeuristic analysis is smart, rules-and-pattern-based analysis that reads observable cues to surface what is most likely happening in your swing — a confident, data-backed estimate, not a guess.
- Heuristic DataIntermediateHeuristic data is information read through encoded expert rules of thumb to surface the most likely pattern quickly and reliably — a confident estimate, not a measured result.
- Heuristic EngineIntermediateThe heuristic engine is the deterministic, rules-based part of SwingVantage that runs first on every analysis — no external AI call required.
- Improvement DeltaIntermediateAn improvement delta is the measured difference between a baseline value and the most recent measurement for the same metric. The hard number behind "did I get better?"
- Instant EstimateBeginnerAn Instant Estimate is a fast, heuristic-only analysis result available immediately after upload — clearly labeled as an estimate derived from rules, before any AI-enhanced processing completes.
- Interpreted ValueIntermediateAn interpreted value is a judgment or label that emerged from AI reasoning applied to raw data — such as 'likely timing issue' or 'probable hip stall' — rather than from a direct measurement or a deterministic rule.
- Kinematic ChainIntermediateThe kinematic chain is the sequence of body segments — from ground to tip — through which force and speed are transferred in a swing, with each segment's energy amplifying the next.
- Landmark TrackingIntermediateLandmark tracking follows the position of each detected body keypoint across consecutive video frames. This creates a time-series trajectory for every joint that enables timing and velocity measurements.
- Lighting ConditionsBeginnerLighting conditions describe how evenly and brightly the subject is illuminated — poor lighting is one of the top causes of low-quality video and degraded pose estimation.
- Measured ValueBeginnerA measured value is a number that came from a real sensor or instrument. A launch monitor, radar gun, or wearable — and was not inferred or estimated from video or rules.
- Mobile Motion CaptureIntermediateMobile motion capture is the process of using a smartphone camera and on-device pose estimation to track body movement in real time or from a recorded clip — no specialized hardware required.
- Mock / Demo DataBeginnerMock or demo data is pre-generated illustrative data used in product demos, onboarding flows, and feature previews — always labeled to distinguish it from real user data.
- Motion LabBeginnerMotion Lab is the browser-based 3D motion analysis tool in SwingVantage that turns your video into a three-dimensional avatar and timeline, letting you rotate, scrub, and measure your swing without any installed software.
- Motor LearningIntermediateMotor learning is the scientific study of how the nervous system acquires, refines, and retains skilled movement. The theory underlying how practice actually changes your swing.
- Movement SequencingAdvancedMovement sequencing is the timed order in which body segments accelerate and decelerate through a swing — correct sequencing multiplies speed; incorrect sequencing bleeds it.
- One-Fix PlanBeginnerThe One-Fix Plan is SwingVantage's core methodology: identify the single highest-impact fault, build a focused practice plan around fixing only that fault, and confirm the fix with a structured retest before moving on.
- Outlier in Swing DataIntermediateAn outlier is a data point that falls far outside the normal range for that metric and session. It may represent a genuine extreme swing or a measurement artifact. It requires honest handling before being used in averages.
- Phone Video LimitationsBeginnerPhone video limitations are the practical constraints of recording on a smartphone — lens distortion, stabilization artifacts, variable frame rate, and compressed color depth — that can reduce analysis accuracy relative to purpose-built cameras.
- Placeholder DataBeginnerPlaceholder data is a temporary illustrative value shown in a UI before real data is available — always explicitly labeled as a placeholder so it is never mistaken for an actual measurement or estimate.
- Player ProfileBeginnerThe Player Profile is the persistent record of an athlete's sport, skill level, swing history, fault patterns, progress metrics, and linked sessions that SwingVantage uses to personalize every analysis and recommendation.
- Pose EstimationIntermediatePose estimation is the computer-vision process that detects the positions of major body joints (keypoints) in each video frame. This produces the skeleton that SwingVantage uses to measure angles and movement patterns.
- Practice PlanBeginnerA practice plan is a structured, time-blocked schedule of drills and tasks designed to address your diagnosed fault with the right repetitions, feedback cues, and retest protocol.
- Practice TransferAdvancedPractice transfer is how much a skill learned in a practice environment carries over to real performance — the ultimate measure of whether your training actually worked.
- Primary vs. Secondary FaultIntermediateThe primary fault is the swing issue with the highest severity and impact on performance; the secondary fault is the most likely co-existing issue.
- Progress TrackingBeginnerProgress tracking is the longitudinal record of how your key metrics change over multiple sessions and retests, displayed as a timeline that shows improvement, plateaus, and regressions.
- Random PracticeIntermediateRandom (or variable) practice mixes different skills, shot types, or conditions within a session — producing better long-term retention and transfer to real play than blocked repetition.
- Real / Live DataBeginnerReal / Live data is data captured from an actual user session or sensor — not a placeholder, not a demo, not a mock — and is labeled accordingly so you can trust it as genuine input to analysis.
- Recommendation EngineIntermediateThe recommendation engine ranks possible fixes by impact and confidence so you get one high-leverage priority fix — not twenty competing tips.
- Recovery SessionIntermediateA recovery session is a low-intensity practice day focused on reinforcing patterns at slow speed, flushing fatigue, and keeping motor grooves active without accumulating more load.
- RetestBeginnerA retest is a short follow-up protocol attached to each recommendation — how many shots. This metrics, and what counts as success — that confirms whether a fix actually worked.
- Retest DeltaIntermediateA retest delta is the change between a pre-drill baseline and the post-drill retest measurement for the same specific metric targeted by that session's fix — the short-cycle confirmation of whether a single training session moved the needle.
- Rules EngineIntermediateThe rules engine is the configuration-driven core that checks your shot data and symptoms against sport-specific target windows to identify the best-fitting pattern.
- Sample SizeIntermediateSample size is how many swings or shots a metric is based on — small samples produce more noise and lower confidence. Larger samples produce more reliable estimates.
- SeverityIntermediateSeverity is how significant a swing fault is expected to be for performance, labeled Critical, High, Moderate, or Low.
- Signal vs NoiseIntermediateSignal is the real, repeatable pattern in your swing data; noise is the random variation that looks like a pattern but isn't. Distinguishing the two is what separates useful analysis from false precision.
- Skeleton OverlayBeginnerA skeleton overlay is the on-screen visualization of detected body joints and the lines connecting them, drawn over your video so you can see exactly what the system tracked.
- Skill AcquisitionIntermediateSkill acquisition is the process by which practice and feedback cause a movement pattern to become more automatic, consistent, and robust under pressure — the goal of all training.
- Skill TreeBeginnerThe Skill Tree is a visual map of a sport's key technical skills, organized into an unlockable hierarchy that shows where you stand and what to develop next.
- Stability vs MobilityIntermediateStability vs mobility is the biomechanical principle that joints alternate between roles. Some must be stable anchors, others must be mobile movers — and faults often come from reversing these roles.
- Swing DecodeBeginnerSwing Decode is SwingVantage's golf-specific analysis view that breaks the swing into distinct phases — address, takeaway, top, downswing, impact, and follow-through — and annotates each phase with the relevant mechanics detected.
- TempoBeginnerTempo is the timing relationship between the two halves of a swing — the rhythm that separates efficient, repeatable mechanics from a rushed or laboured transition.
