🎮 Gamepad — Vibration Test

Gamepad Vibration Test helps you check if your controller’s vibration is working. Vibration makes games feel more real by giving small shakes during actions like crashes, hits, or goals. If your controller is not vibrating, this test will show you if the problem is with the gamepad or the game. You don’t need to install anything—just connect your controller and press start to feel the vibration.

Disclaimer

This Gamepad Vibration Test is a diagnostic utility that runs entirely in your browser using the HTML5 Gamepad API. It attempts to send vibration commands to connected controllers. Results vary by browser, operating system, controller model, and drivers. This tool does not collect or transmit your data — all processing is local to your device. Excessive or prolonged vibration testing can accelerate motor wear or drain batteries; use responsibly. If your controller is under warranty, contact the manufacturer before attempting physical repairs.

Each major section is boxed for clarity.

Understanding Gamepad Vibration Technology

History & Evolution

Haptic feedback in controllers has evolved from simple buzzing to sophisticated, multi-channel feedback systems. Early consoles offered on/off motors. Over time, manufacturers added dual-motor setups, variable intensity control, programmable waveforms, and in high-end hardware, advanced haptic actuators (e.g., adaptive triggers and linear actuators found in recent gamepads). Today’s controllers aim to produce a broad palette of sensations — from faint footsteps to heavy explosions — by combining motors and controlling intensity, timing, and pattern.

How Vibration Motors Create Feel

Most controllers use small DC motors with eccentric weights. When the motor spins, imbalance produces oscillatory forces transmitted to your hands. There are two common styles:

• Low-frequency (strong) motors: larger mass, slower oscillation, produces heavy rumble and "thump" sensations.
• High-frequency (weak) motors: smaller mass, faster oscillation, produces buzzy, sharp feedback for details.

Some modern devices use more advanced actuators (e.g., linear resonant actuators or voice-coil actuators) for richer, more precise haptics, but the majority of consumer gamepads rely on the dual motor approach.

API: How Browsers Talk to Motors

The web Gamepad API exposes a vibrationActuator on compatible gamepad objects. When available it allows sending standardized "effects" (e.g., dual-rumble) with parameters like intensity for each motor and duration in milliseconds. Browser implementations and driver behavior ultimately determine how these commands are translated to electrical signals sent to motors.

Testing Methodology — How to Run Effective Tests

Environment & Preparation

1. Room setup: test in a quiet place so you can also hear motor noises that indicate mechanical issues.
2. Power: charge your controller or use a wired connection to avoid battery-induced weakness.
3. Warm-up: run a short 5–10 second low-intensity test to bring motors up to operating temperature.
4. Surface: hold the controller in hand — placing it on soft or hard surfaces changes sensation and can mask problems.

Test Types & Patterns

Use a range of patterns and intensities to expose different failure modes:

• Static intensity tests: set a fixed intensity (0.2, 0.5, 0.8, 1.0) to check linearity of motor strength.
• Pulse tests: short on/off pulses (e.g., 100ms on, 100ms off) to test start/stop response and latency.
• Ramp tests: slowly ramp from 0 to 1 and back to detect non-linear regions where the motor response changes unpredictably.
• Alternating tests: alternate weak/strong to check independent motor control and potential cross-talk.
• Full diagnostic sequence: automated run that repeats the above patterns in a short script — useful for repeatable reporting.

How to Interpret Results

Normal vs Problematic Behavior

Normal: Both motors respond to intensity changes, start quickly when commanded, stop promptly, and scale roughly linearly across intensities. Weak motor should feel buzzy; strong motor should feel heavy. Combined patterns should feel clearly different than single motor patterns.

Problem signs:

• One motor silent at all intensities — possible hardware failure.
• Motor spins but strength is significantly weaker than expected — motor wear, power issue, or driver limiting.
• Delayed start or stop — could indicate Bluetooth latency, driver buffering, or JS timing issues when running from the browser.
• Grinding, clicking, or mechanical noise — internal damage or debris; consider repair.
• Motor keeps running after stop commands — driver or hardware motor control stuck.

Platform & Browser Compatibility

Browser Differences

Support across browsers is inconsistent:

• Chrome & Edge (Chromium-based): Best support on Windows and Android for vibrationActuator and dual-rumble.
• Firefox: Partial support depending on OS; older builds may not support vibration actuators for gamepads.
• Safari: iOS/macOS support is limited or absent for gamepad vibration in many versions.

Operating System Notes

OS and drivers play a role:

• Windows: Generally good driver support for Xbox controllers and many wired/wireless gamepads. Edge/Chrome usually works well.
• Android: Many devices allow full vibration via browser with supported controllers (USB / Bluetooth). Mobile browser behavior varies.
• macOS / iOS: Support is spotty; PlayStation DualSense/DualShock may be more compatible through native apps than browsers.
• Linux: Support depends on kernel drivers and browser build; tests are recommended on target setups.

Platform-Specific Troubleshooting (Step-by-step)

Windows

1. Use a wired connection (USB) to rule out Bluetooth latency/power issues.
2. Install/update drivers: for Xbox controllers, use Microsoft drivers; for others, check vendor sites.
3. Test in Chrome/Edge. If vibration works in a game but not in the browser, it’s likely browser limitations.
4. Check Windows Power Settings and Device Manager power management options (disallow power saving for USB hubs).

macOS

1. macOS has weaker native support for some controllers; wired connections sometimes help.
2. Test with different browsers — note that Safari tends to lag in Gamepad API support.
3. Try third-party drivers (e.g., DS4Windows on Windows equivalent for macOS) with caution — they can enable features but also introduce instability.

Android

1. Connect via USB OTG where possible for stable power and lower latency.
2. Chrome on Android tends to have the best Gamepad API support; test there first.
3. Bluetooth power saving may reduce vibration strength — ensure device is not in power saving mode.

Linux

1. Make sure udev rules and kernel drivers are up-to-date for the gamepad in question.
2. Test with Chromium builds; results vary depending on distro and kernel version.
3. Use tools like jstest or SDL-based apps to verify hardware support outside the browser.

Common Issues & How to Fix Them

No Vibration

1. Confirm controller supports vibration by checking manufacturer specs.
2. Try another app or game known to use rumble — if it works there, the browser or page may not support vibration.
3. Switch to Chrome/Edge and retest. If still no vibration, test another controller to isolate device vs environment.

Weak Vibration

1. Charge the controller fully or replace batteries.
2. Test wired vs wireless — wired often yields stronger feedback.
3. Confirm there’s no OS power-saving throttle applied to peripherals.

Motor Keeps Running / Won’t Stop

1. Use the tool’s Stop button (calls actuator.reset()).
2. If persistent, disconnect the controller or reboot the device. Persistent running may indicate firmware/hardware issue.

One Motor Fails

If one motor never produces sensation while the other works across tests, it’s likely a hardware failure — consider warranty or repair/replace options (see maintenance section).

Maintenance, Care & When to Repair

Everyday Care

• Keep controllers in a cool, dry place. Excess heat accelerates motor wear.
• Avoid dropping or striking controllers; motors and internal mounts are delicate.
• Keep dust out of ventilation holes and avoid liquids near openings.

Battery & Power

Vibration uses noticeable battery power. If your controller’s vibration weakens during a session, the battery charge is a likely suspect. For testing, prefer wired mode or a fully-charged controller.

Repair Considerations

Replacing vibration motors usually requires opening the controller and sometimes soldering. For expensive or warranty-covered controllers, contact the manufacturer. For older or cheap controllers, replacement is often cheaper than repair.

Developer Notes — Using Vibration in Games & Apps

Design Principles

• Use vibration sparingly — overuse desensitizes players and can cause fatigue.
• Match vibration intensity and pattern to in-game events — subtle taps for footsteps, strong rumbles for explosions.
• Provide user options: allow players to reduce, invert, or disable vibration (accessibility).

Implementation Tips

1. Test on multiple controllers — intensity mapping differs between models.
2. Consider using short bursts for precise synchronization with audio/visual events.
3. Respect power constraints on wireless devices; avoid long continuous vibration sequences unless necessary.

Example (Web) Pseudocode

// Check vibration support
const gp = navigator.getGamepads()[0];
if (gp && gp.vibrationActuator) {
  gp.vibrationActuator.playEffect('dual-rumble', {
    startDelay: 0,
    duration: 200,
    weakMagnitude: 0.4,
    strongMagnitude: 0.8
  });
}
    

Accessibility & Inclusive Design

Why Accessibility Matters

Not all players can perceive vibration equally — some have sensory impairments or use alternative controllers. Offer settings that allow disabling or complementing vibration with visual/audio cues.

Practical Options

• Toggle vibration on/off in options menu.
• Adjust intensity scales and provide presets (High/Medium/Low/Off).
• Provide alternative cues (screen flash, sound effect, controller LED) for important events.

Extensive FAQ

Q: My controller vibrates in games but not in this page — why?

A: Many games use native APIs or drivers that have deeper access than browser APIs. Also, some browsers restrict vibration for security/performance reasons. Try Chrome or Edge, or test with a wired connection.

Q: Can vibration damage my controller?

A: Normal testing won’t damage the controller. However, continuous maximum-intensity tests for very long periods can increase wear. Use short bursts and allow rest periods during diagnostics.

Q: Why does one controller feel stronger than another at the same intensity number?

A: Intensity values are normalized by the browser, but hardware differences (motor size, placement, mounting) mean the subjective feel will differ. Test multiple controllers to build a baseline.

Q: The motor behaves non-linearly (weak at mid values, strong near max). Is that normal?

A: Some motors have non-linear torque curves and motor drivers may also implement non-linear scaling. Ramp tests help reveal non-linear regions.

Q: The vibration stops when I switch tabs. Is that expected?

A: Yes. Many browsers throttle or suspend background pages for performance/battery reasons. Keep the tab active during testing.

Technical Reference & Developer Resources

Key concepts and API notes for developers:

• vibrationActuator.playEffect('dual-rumble') — standard web effect with weakMagnitude, strongMagnitude, duration.
• reset() — try to stop all ongoing vibration effects.
• JavaScript timing is not real-time; for microsecond precision, native APIs or middleware may be required.

Always test across hardware and platforms when designing haptic experiences — the same waveform can feel dramatically different between controllers.

When to Repair vs Replace

If vibration fails on one motor but the rest of the controller functions normally, your options are:

• Warranty service: If under warranty, contact the manufacturer for repair or replacement.
• Repair: Motor replacement is possible but may be costly and requires micro-soldering/disassembly skill.
• Replace: For inexpensive controllers, replacement is often the most practical solution.

Pro Tips — Final (Big List)

This section collects practical, battle-tested tips to get the most out of vibration testing and long-term controller health. Use these as a checklist when diagnosing or comparing controllers.

Quick Checklist (Use Every Time)

1. Always test wired first — gives baseline behavior.
2. Run a short warm-up at low intensity before any diagnostic sequence.
3. Use pulse and ramp tests to identify non-linear motor response.
4. Record results (subjective notes + optional CSV logs) to compare controllers later.
5. If possible, test the same controller on another PC/phone to isolate environment issues.

Long-Term Care Tips

• Store controllers away from heat and direct sunlight.
• Use protective carrying cases for travel.
• Replace rechargeable batteries when they no longer hold sufficient charge for strong vibration.
• Periodically run short diagnostic tests to spot gradual degradation early.

Tips for Developers & QA

• Include haptics toggles and intensity scaling in-game options — users have widely different preferences and hardware.
• Create in-game diagnostics similar to this page — QA can use them to test builds across devices quickly.
• Document the haptics mapping you expect for engines and middleware (e.g., how strongMagnitude maps to game events).
• Automate tests where possible — repeated ramp/pulse patterns can be scripted in QA pipelines to detect regression.

Accessibility & Player Comfort

• Offer alternatives to vibration (visual cues, sound cues) for players with sensory differences.
• Avoid persistent high-intensity vibration — it can cause discomfort and fatigue.
• Consider user-controlled vibration duration limits (e.g., maximum 2–3s continuous by default).

If You Must Open the Controller

• Only open a controller if out of warranty and you’re comfortable. Keep ESD safety in mind.
• Take photos during disassembly so you can reassemble correctly.
• Replacement motors are inexpensive but require careful soldering and steady hands.
• If uncertain, a reputable electronics repair shop is a safer option.

Final Words

Vibration testing is both practical and surprisingly informative — it tells you about hardware health, driver quality, OS support, and design choices by controller manufacturers. Use this tool and guide as a baseline for sanity checking your gear, designing better haptic experiences, and keeping your controllers healthy for years of play.
