Touchpad Test — DualSense & DualShock 4 checker
A controller touchpad test verifies the touch surface on your PS5 DualSense, DualSense Edge, or DualShock 4 reports input accurately. Our free browser-based tester captures touchpad input via pointer events on an in-page canvas, runs a guided two-phase sequence (8 seconds of swipe tracking plus 3 click attempts), and reports sample rate, multi-touch detection, coverage map, dead zones, and click reliability. Used by PS5 players to verify hardware health before contacting Sony warranty support.
How the touchpad test works
Connect your controller
Plug in via USB or pair over Bluetooth. Press any button to register the gamepad. On most Chromium browsers, the DualSense and DualShock 4 touchpads expose themselves as system pointer devices when wired — swipes generate pointermove events on whatever window has focus.
Swipe phase (8 seconds)
Slide your finger across the on-screen canvas in figure-8 patterns covering the whole surface. The tester captures every pointermove event, computes samples per second (over 60/s is healthy), tracks simultaneous pointers for multi-touch detection, and marks which of 18 grid cells (6 × 3) have been touched for coverage analysis.
Click phase (3 attempts)
Press down firmly on the touchpad until it clicks. The tester captures three click attempts with a 5-second timeout each, evaluating either pressure (≥0.5) or sustained duration (≥80 milliseconds) as a successful click signal. This catches the underlying touchpad-button independent of swipe input.
Coverage and dead-zone analysis
After both phases, untouched cells in the coverage grid surface as potential dead zones — areas of the touchpad surface that did not register input. Dead zones are only meaningful when total coverage reaches at least 10 of 18 cells; below that, we mark the dead-zone signal as insufficient data rather than failing.
Composite verdict
Verdict combines worst-of-four signals: sample rate, click success count across 3 attempts, max simultaneous pointers seen, and dead-zone count. Multi-touch is capped at Functional severity (not Faulty) because many setups expose only one pointer at a time even on healthy hardware.
What the metrics mean
Four independent signals, each classified separately. The verdict is the worst classification across all four.
| Signal | Verdict | Threshold |
|---|---|---|
| Sample rate | Pointer events per second during swipe | Healthy ≥ 60/s · Functional ≥ 30/s · Partial ≥ 15/s · Faulty < 15/s. A wired DualSense on Chromium typically delivers 120/s; Bluetooth can drop to 60/s; below 30/s indicates polling-rate throttling or driver issues. |
| Click success | Successful clicks of 3 attempts | Healthy = 3/3 · Functional ≥ 1/3 · Faulty = 0/3. Inconsistent clicks usually mean the underlying tactile switch is failing — common on heavily used controllers past 2 years. Replaceable on most pads. |
| Multi-touch | Max simultaneous pointers detected | Healthy ≥ 2 · Functional = 1 · Capped at Functional severity on 0 (browser/driver limitation, not always hardware fault). True multi-touch confirmation requires WebHID Mode (v1.1). |
| Dead zones | Untouched cells of 18-cell grid | Healthy = 0 · Functional 1–2 · Partial 3–5 · Faulty 6+. Only meaningful when total coverage ≥ 10 cells. Persistent dead zones in the same region indicate physical damage to the capacitive layer. |
Compatible devices
Touchpads are exclusive to the Sony PlayStation controller line. Best results on Chromium browsers (Chrome, Edge, Opera, Brave) with a wired USB connection.

Touchpad questions
Most PS5 owners discover touchpad issues mid-game — a misregistered map open, a missed crouch bind in Warzone, an intermittent click. By the time you suspect a fault, the symptom may be too inconsistent to reproduce on demand. Our test provides a structured 11-second diagnostic — 8 seconds of swipe coverage plus 3 click attempts — that surfaces dead zones, slow polling, and click failures in a reproducible way that can be screenshotted for a Sony warranty claim.
When you connect a DualSense or DualShock 4 over USB to a Chromium-based browser on a PC, the controller exposes its touchpad as a system pointer device. Finger swipes on the physical touchpad generate pointermove events identical to a touchscreen on the focused window. Our tester captures these events through an in-page canvas and analyzes their rate, position, and pressure.
The canvas is the input target the browser is listening on — pointer events only fire when your cursor is inside it. Most users have their DualSense touchpad mapped to control the system cursor, so swiping moves the cursor across the screen. As long as the cursor passes through the canvas during your swipe, events register. Keep the browser window focused and the cursor over the canvas during the swipe phase.
A wired DualSense on Chromium typically delivers around 120 pointer events per second during continuous swipes. DualSense over Bluetooth drops to roughly 60/s. DualShock 4 over USB lands around 100/s. Anything below 30/s suggests polling-rate throttling — driver issues, Bluetooth interference, USB hub contention, or a degraded controller cable.
Multi-touch on the DualSense touchpad has historically been Chromium-version-dependent. Recent Chrome versions (since 110) expose simultaneous pointers reliably. Older Chromium builds, Edge before 2024, and some driver configurations only surface one pointer at a time even when the hardware supports multi-touch. The verdict caps this signal at Functional rather than Faulty because single-pointer detection is often a browser limitation, not hardware failure.
Moderately. The test divides the touchpad into an 18-cell grid (6 columns by 3 rows). Cells you never touch during the swipe phase show as potential dead zones. The detection is only meaningful when you cover at least 10 of 18 cells — below that, we mark coverage as insufficient. For confirmed dead zones, retest with a deliberate slow sweep across the suspect region; a true dead zone produces zero events in that area regardless of finger contact.
Underneath the capacitive surface, every PS-line touchpad has a single mechanical micro-switch — typically rated for 100,000 actuations. Pressing the touchpad hinges the entire surface down to actuate this switch. The click is independent of where you press on the surface. After heavy use, the switch can develop intermittent contact, producing missed or false clicks. Replacement switches cost $1–3 plus your own soldering labor.
Yes, significantly. v1 ships pointer-event mode, which is limited by the OS pointer-translation layer — coordinates are normalized to your screen, pressure is binary, and multi-touch can be inconsistent. v1.1 will add WebHID Mode that reads the raw HID stream from the controller, giving us native touchpad coordinates (0–1920 horizontal, 0–1080 vertical on DualSense), precise pressure values, and reliable multi-touch separation. Same WebHID upgrade path as our Gyro Test.
