    Add live per-step form feedback based on joint angles

    Extends pose angle tracking with knee bend (hip-knee-ankle), then uses
    it alongside the existing elbow/shoulder angles in a new
    PoseStageAdvisor to give a short live cue for whichever step of the
    approach is in progress: push-away on step 2, downswing on step 3,
    backswing on step 4, and knee-bend/arm-extension on the final step.
    Thresholds are starting defaults, not measured coaching data, and are
    expected to be retuned against real approach footage.

    Also fixes a layout bug found while testing this live: the new
    feedback text was chained via ConstraintLayout's toBottomOf to the
    step banner above it, so whenever that banner was hidden (GONE) the
    feedback text rendered at its collapsed zero-height position instead
    of staying put, landing on top of the recording indicator. Both now
    sit in a plain vertical LinearLayout, which collapses GONE children
    correctly.

    Add live final-position feedback and fix step detection accuracy

    Shows a live banner as each step of the approach is counted, ending in
    "FINAL POSITION - RELEASE!" once the 5th footfall lands. Also fixes
    LiveStepDetector's peak-prominence check, which compared a candidate
    footfall only to its immediate neighboring frame and silently dropped
    real steps that landed across several closely-spaced frames; it now
    tracks the true rise/fall trough on each side instead. Switches
    PoseAnalyzer to ML Kit's faster base pose model (the accurate model was
    starving the peak detector of frames on unaccelerated hardware), and
    makes LiveStepDetector's stillness-based reset toggleable, currently
    off for easier testing against recorded reference clips.

Project Proposal

TODO: Paste in the team's original submitted proposal here (verbatim, or a cleaned-up version with the same content). This file was scaffolded automatically as part of the required docs/ structure and does not yet contain the actual submitted proposal text.

Suggested sections to include

  • Problem statement / motivation
  • Target users
  • Proposed solution and key features
  • Scope (in-scope vs. out-of-scope for this project)
  • Success criteria
  • Team members and roles

Working summary (placeholder, derived from the current codebase — replace with the real proposal)

PinPoint (working name "BowlEye" in code) is an Android app that helps bowlers improve their approach and delivery form by recording video through the phone camera, running on-device pose detection (ML Kit) to track body landmarks in real time, and giving feedback on step timing, joint angles, and delivery phase.
