GaitPilot Universal TV Companion Guide (gaitpilot.com/tv)

Welcome to the GaitPilot Universal TV Companion Guide. GaitPilot TV transforms any television, smart display, trackside monitor, or clinic tablet into an ambient 16:9 widescreen biomechanical dashboard with zero app installation.

🔒 Athlete-Initiated Privacy & Session Control

A foundational security principle across GaitPilot is that only the walker can start a session and broadcast telemetry.

  • No Remote Waking: A coach, follower, or Guardian cannot wake up an athlete's sensors, trigger tracking, or view movement without the walker actively pressing START on their mobile phone.
  • Explicit Screen Pairing: A TV screen cannot connect to an athlete's workout unless the athlete physically enters the screen's temporary 4-digit code into their mobile phone under Settings → Link TV / Smart Display.
  • Instant Disconnect: The athlete maintains an active Linked Displays inventory inside the mobile app. With a single tap, the walker can unlink any display at any moment.
  • Automatic Session Closure: When the walker taps STOP on their mobile phone, the live WebSocket feed terminates immediately, and connected TV screens return to standby.

🔄 Dedicated Display Binding & "Last Linked Wins" Protocol

To keep big-screen viewing intuitive and prevent confusing split-screen clutter or data cross-talk, GaitPilot enforces a dedicated single-session display binding model:

  • Ephemeral Single-Use Codes: Each 4-digit numeric code is cryptographically unique, valid for 10 minutes, and permanently consumed and erased from the server the moment a phone pairs with it. A code cannot be intercepted or reused by a second device.
  • Dedicated 16:9 Display Focus: A physical television or trackside smart display renders exactly one athlete's active workout at a time, ensuring that coaches and observers have an unambiguous, distraction-free view of that walker's live symmetry and vitals.
  • Last Linked Wins Resolution: If another athlete or coach subsequently pairs the same television screen by entering a freshly generated 4-digit code, the server automatically re-binds the television display to the newly linked athlete and cleanly unbinds the previous session. The previously linked phone receives an unlinked status notification in its display inventory, guaranteeing that workouts never overlap or bleed into each other.
  • Complete Session Purge (resetSessionState()): Every time a new workout session starts, the TV interface immediately executes a comprehensive memory and canvas purge: completely wiping the GPS breadcrumb trail, resetting speed to 0.0, zeroing out step and cadence counters, and clearing chat feeds. This guarantees zero ghost data or residual metrics from previous walks appear on screen.

📺 Big-Screen Hardware Compatibility

GaitPilot TV runs natively inside any modern HTML5 web browser. No app store downloads or APK installations are required:

  • Living Room Televisions: Google TV, Android TV, Samsung Tizen Smart TVs, LG webOS TVs, Amazon Fire TV (Silk Browser), and Apple TV (via AirPlay or browser).
  • Trackside & Gym Displays: Widescreen PC monitors, smart mirrors, and wall-mounted tablets.
  • Clinical & Laboratory Monitors: Secondary HDMI or wireless displays hooked to coaching workstations.

🚀 Easy 4-Digit Pairing Walkthrough

Setting up a big-screen companion takes only seconds:

  1. Launch Browser on Your Display: Open the web browser on your TV and go to https://gaitpilot.com/tv.
  2. Read the Ephemeral Code: The screen presents a high-contrast standby screen with a unique, glowing 4-digit numeric code (e.g., 4821).
  3. Link in the Mobile App: In the GaitPilot phone app, open Settings → Link TV / Smart Display, enter the 4 digits, and optionally assign a nickname (such as "Living Room Sony 65" or "Clinic Trackside Display").
  4. Automatic Activation: As soon as the walker starts an active session on the phone, the linked TV wakes up automatically, transitioning from the standby card to the live 16:9 telemetry command deck.

📊 16:9 Ambient Screen Modes

The TV Companion provides two dedicated widescreen views designed for effortless viewing from across the room. When linking any TV or display in the mobile app, walkers can configure how that screen behaves: * Flexible / Either (Allow Switching on Screen): Displays interactive role toggle buttons (Coach / Guardian), allowing viewers in the room to switch between biomechanics and safety tracking views at any time with automatic chat synchronization. * Dedicated Guardian Safety: Locks the display strictly to Guardian mode (map, battery vitals, watchdog alerts, family cheers) with the switcher hidden. * Dedicated Coach Command: Locks the display strictly to Coach mode (biomechanics dials, GCT balance, cadence pacer, drill cues) with the switcher hidden.

1. Coach Biomechanics Deck (?role=coach)

Designed for coaches, athletic trainers, and physical therapists who need granular movement diagnostics during workouts: * Real-Time Gait Symmetry Dial: A prominent center radial gauge indicating bilateral symmetry percentage. * Cadence Metronome & Pacer: Current steps-per-minute alongside the target cadence delta. * Bilateral Ground Contact Time (GCT): Left vs. Right foot contact duration in milliseconds. * Impact Braking Force: Peak vertical deceleration in G-forces for both feet. * Interactive Terrain Map: Dark-mode course trail with speed and elevation profiles.

2. Guardian Safety View (?role=guardian)

Designed for family members and caregivers who want ambient reassurance while an athlete or elder is out walking: * High-Visibility GPS Map: Smoothly tracked street-level beacon following the walker's path. * Vitals & Battery Telemetry: Large, high-contrast indicators for phone battery percentage, walking pace, and heart rate. * Audible Safety Watchdog Alerts: If an antalgic collapse or fall is detected by the phone's safety engine, the TV displays an emergency alert banner and sounds an audible room chime.

🌐 Independent Global Cloud Streaming

The TV companion connects directly to the GaitPilot cloud relay over low-latency WebSockets (WSS).

Once paired, the phone and the television do not need to be on the same Wi-Fi network. An athlete can start walking outdoors miles away on cellular LTE/5G, while a coach or guardian in another room—or another country—monitors live biomechanics in real time with sub-second latency.

🎛️ Master Streaming Toggle: "Stream Walks to Linked Screens"

In the GaitPilot mobile app under Settings → TV & SMART DISPLAYS: * One-Tap Transmission Control: The top of the screen features a master switch: "Stream Walks to Linked Screens". * Instant Privacy: When toggled OFF, live telemetry transmission to TV screens is immediately withheld, conserving phone battery and mobile data without deleting your paired screen configurations. * Persistent Screen Preservation: The phone's local storage retains all paired displays. Even when cloud backend instances scale down or restart, your linked screens remain saved on the phone and automatically re-establish connections when a walk starts.

♿ Screen Reader Accessibility & Google TV Remote Microphone Guidance

The TV companion interface is optimized specifically for television screen readers (TalkBack on Google TV / Android TV, VoiceOver on Apple TV/iPad, and NVDA / JAWS on PC): * Interactive-First D-Pad Traversal: The interactive Living Room Chat & Quick Cheer deck is structured first in the DOM/focus order. Upon switching to the live walk view, screen reader users land directly on the chat and quick cues ("Target Cadence!", "Stand Tall!", "Looking Great!") rather than having to click through 30+ passive metric boxes. * Unified Card Aggregation (No "Bit-by-Bit" Fragmentation): * Rather than announcing each individual number, unit, and label separately ("0.0", "MPH", "Speed"), metric cards are consolidated into single unified stops (#card-vitals, #card-biomechanics). * TalkBack reads out the full composite telemetry in one smooth, human-friendly utterance (e.g., "Walking Vitals: Speed 3.2 miles per hour, Cadence 118 steps per minute, Heart Rate 124 beats per minute, Phone Battery 85 percent" and "Biomechanics Balance: Symmetry 96 percent, Cadence Target on pace. Ground contact time: Left 240 milliseconds, Right 245 milliseconds. Strike impact: Left 1.8 G, Right 1.9 G"). * Internal visual-only markup is cleanly marked aria-hidden="true" to prevent navigation stutter. * Zero "Article" Clutter: All HTML role="article" attributes have been completely eliminated from the TV interface, eradicating repetitive, meaningless "article" announcements when navigating with a television remote. * Google TV Remote Microphone vs. On-Screen Dictation: * System Hardware Constraint: On Google TV remotes, pressing the physical microphone button triggers the television's built-in operating system assistant (Google Assistant / Gemini) rather than the web browser. * How to Dictate Messages: To speak a coaching cue or cheer from the TV dashboard, navigate using TalkBack or the D-pad arrow keys to the on-screen microphone icon (🎙️) next to the chat box and press OK/Enter to start browser-level voice dictation, or select one of the high-contrast quick cheering chips.
