Turn angle distribution

0 completed turns

No completed turns yet.

Each completed gyro camera movement is integrated into an in-game turn and counted here. Distance from the center is the in-game turn angle (degrees); direction shows FPS camera movement direction. Turn angles use JoyShockMapper GYRO_SENS directly as the calibrated camera-angle ratio. REAL_WORLD_CALIBRATION / IN_GAME_SENS is used only to model the mouse output JSM must emit; JSM compensates IN_GAME_SENS so it does not change the intended camera angle. The radial scale automatically follows the 90th percentile of completed turns (rounded up to 10°, with a 50° minimum), so rare large turns do not compress the main aiming cluster. Turns outside the displayed 90% region are retained for the distribution and aiming-profile statistics but are not forced onto the heatmap edge. The distribution keeps the high-density aiming region detailed even when a rare large turn expands the heatmap: 5° bins from 0–50°, 10° from 50–100°, 20° from 100–200°, 25° from 200–400°, 50° from 400–800°, then 100° bins. Each bin shows both percentage and turn count. GYRO_OFF movements are excluded.

Time spent at each effective sensitivity

This histogram is time-weighted: each IMU sample contributes its elapsed time to the effective sensitivity bucket, so it shows where the player actually spends time rather than simply counting samples.

Saved runs are kept in this browser using localStorage. Accuracy is optional and entered manually from Halo Infinite; the table does not infer that one configuration is better from accuracy alone.

The analyzer examines the actual WebHID payload delivered by the browser. It reports byte offsets, signed 16-bit LE activity, and likely motion fields.

A candidate is only a statistical hint: acceleration, buttons, timestamps and other HID fields can also move. Use the analyzer while physically rotating the controller and compare the three adjacent 16-bit fields. “Use as gyro” changes the live parser for testing and can be reset.

The controller's raw IMU values are decoded from the DualSense HID reports. Factory sensor calibration from feature report 0x05 is applied before user deadzone/filter/JoyShockMapper processing; “Calibrate gyro” adds a user bias offset while the controller is stationary. A JoyShockMapper config can be loaded locally; the parser understands GYRO_SENS, MIN/MAX_GYRO_SENS, MIN/MAX_GYRO_THRESHOLD, GYRO_CUTOFF_SPEED, GYRO_AXIS_X/Y, MOUSE_X/Y_FROM_GYRO_AXIS and common GYRO_* acceleration modifier keys. JoyShockMapper sensitivity is a multiplier, so processed camera velocity is raw angular velocity multiplied by the effective sensitivity.

WebHID requirements

This controller mode requires a Chromium browser with WebHID support and a secure context such as HTTPS or localhost. USB is recommended for initial testing. Pair the controller with the operating system first when using Bluetooth, then press Connect DualSense. The app requests Sony DualSense (054C:0CE6) and DualSense Edge (054C:0DF2).
