Vibrate (haptic feedback) API for gamepads

Project Member Reported by mattreynolds@chromium.org, Jul 26 2017 
The Gamepad API should support the haptic feedback motors found in popular modern videogame controllers like the XBox One and DualShock 4.

Support Buffered Haptic Effects
https://github.com/w3c/gamepad/issues/39

The most common haptic feedback mechanism for standard gamepads uses two Eccentric Rotation Mass (ERM) motors positioned in the controller handles. These ERMs have different masses to provide both low-frequency and high-frequency rumble effects. ERMs are typically controlled by a sequence of intensity/duration pairs which tell the motor when to vibrate and how strong the effect should be.

Newer gamepads, including the Oculus Touch and HTC Vive VR controllers, use Linear Resonant Actuator (LRA) motors to provide haptic feedback. LRAs can provide a wider variety of effects, and can often be programmed by sending a buffer of samples that are played back by the LRA as vibration intensity.

Comment 1 by mattreynolds@chromium.org, Jul 26 2017 

I think we should consider three main use cases:

Simple vibration: One haptic device that takes duration/intensity pairs (or sequences of pairs). This would support gamepads with a single motor or more complex gamepads that don't fit the other categories but still support vibration. It will also be appropriate for mobile phones that expose themselves as a gamepad.

Left/Right vibration: Two haptic devices, a low-frequency motor on the left and a high-frequency motor on the right, which each take duration/intensity pairs or sequences of pairs. This would support most modern console gamepads including XBox 360, DualShock 3, and DualShock 4. Most other standard gamepads like the Steam Controller and VR gamepads have haptic devices that can create a low/high frequency rumble effect.

Linear resonant vibration: Two identical haptic devices in the left and right hands which take arrays of samples and play them back as vibration intensity. This would support the Oculus Touch which uses the OVRHaptics API. Other gamepads with LRA-based haptics may also be able to take advantage of this (Nintendo Switch joycons, XBox One rumble triggers, Steam Controller). We should also expect LRAs to become more common in the future.

This leaves out many devices that don't fall into the above categories. For instance, some devices have additional haptics beyond the standard Left/Right rumble. If we expose all haptic devices on the gamepad as an array, it will be difficult for developers to know how the user will experience haptic effects from those additional devices. So, we may want to extend the gamepad API's standard gamepad spec to specify indices for common haptic devices, or maybe add a way for the gamepad mapping to associate a haptic device with a particular button or axis to give developers a hint at what they are vibrating.

Some APIs (for instance, SDL2's haptics) also support force feedback devices like steering wheels and joysticks. These feedback effects rely on the current position, velocity, or acceleration of the input axes and require a fast control loop for a good user experience. Support for these devices is outside the scope of this API.

Fully supporting sending buffers of intensity samples to the LRA for custom effects will require a much more complex API than for simple left/right rumble effects. To keep it manageable, perhaps we can use Web Audio and MediaStreams to stream the data to the device. I think it's fine to leave this out of the initial version of the API and have LRA devices fall back to Left/Right for now.

Implement GamepadHapticActuator

GamepadHapticActuator receives haptics commands and forwards them to
GamepadDispatcher, which dispatches them to the device service. It also
manages the state of promises which have been returned to the user as
the result of haptics commands.

Haptics commands include playEffect, which plays a vibration effect on
the target gamepad, and reset, which stops vibration and resets any
vibration-related state on the gamepad. Both commands return a promise
that is resolved with a result code once the command is completed.

Haptics on Dualshock4 devices are typically not supported by OS-level
haptics APIs, so in order to support vibration effects on these devices
we issue device-specific reports using the raw HID protocol.
Dualshock4ControllerBase implements the common logic for creating the
report buffer from the vibration intensity values. Users should
implement WriteOutputReport to provide the OS-specific logic for sending
the report to the device.

Add haptics for evdev gamepads on Linux

Allow haptics commands to be sent to the platform data fetcher on Linux.
In order for a gamepad to support haptics, the gamepad must be enumerable
through the evdev input event interface. The evdev device must support
the EV_FF feature (force feedback) and FF_RUMBLE (rumble effects).

Don't clear devices during gamepad enumeration

In GamepadPlatformDataFetcherLinux, when enumerating devices with
EnumerateSubsystemDevices, we incorrectly clear the device list. Since
we enumerate multiple subsystems, this causes us to lose all devices
except those found in the last subsystem. This CL instead clears the
device list before enumeration begins.

This CL also combines some subsystem strings that were duplicated.

Avoid recreating haptics in GamepadPlatformDataFetcherWin

A gamepad may be enumerated twice while its active state is still
marked as GAMEPAD_NEWLY_ACTIVE. If this happens, a new
XInputHapticGamepadWin instance will be created without properly
shutting down the previous instance, causing a DCHECK failure.

This situation can occur when a gamepad is enumerated twice before
the polling thread polls the gamepad state, which resets all gamepads
to GAMEPAD_INACTIVE.

To avoid the DCHECK failure, this CL modifies the newly active gamepad
logic so the XInputHapticGamepadWin instance is only created if it was
previously null.

Add bus_type param to GetGamepadStandardMappingFunction

The Standard Gamepad spec lays out a standard configuration for gamepad
buttons and axes. The browser attempts to remap the buttons and axes
reported by connected devices to more closely match the standard. In
most cases, a suitable mapping function can be chosen from the vendor
and product IDs reported by the device.

In some cases this is not sufficient; for instance, some devices are
supported over both USB and Bluetooth and require different mapping
functions in either case. To help select a mapping function in these
cases, a |bus_type| parameter is added to
GetGamepadStandardMappingFunction to specify whether the device is
connected over USB or Bluetooth.

Split GamepadActiveState into separate flags

The Gamepad service allows gamepads to be enumerated by a number
of distinct data fetchers which feed into a central gamepad provider.
The provider is responsible for managing the state and ordering of
connected gamepads as well as issuing notifications when gamepads are
connected or disconnected.

PadState's |active_state| member indicates the gamepad's current
connection status as "inactive" (not receiving updates), "active"
(recently received an update), or "newly active" (just connected).
This state used for three tasks:

* A connection event is fired when the gamepad is first connected.
* A disconnection event is fired when the gamepad is no longer
  connected.
* The data fetcher performs some first-time initialization when the
  gamepad is first connected.

This CL splits |active_state| into separate flags to address each case.

* |is_active| is used to detect the current connection status. It is
  initialized to false for each polling cycle and set to true once
  the PadState is accessed. If this flag is false after a polling
  cycle, the gamepad is considered disconnected.
* |is_newly_active| is initialized to true when the PadState slot is
  allocated and set to false once the gamepad connection event has
  been issued.
* |is_initialized| is initialized to false when the PadState slot is
  allocated and may be set to true by the data fetcher to indicate
  that it has performed first-time initialization for this gamepad.

[Mac] Fix long haptic effects on Xbox One gamepads

On Mac, Chrome includes an internal driver for Xbox 360 and Xbox One
gamepads connected over USB. Vibration effects are issued to these
devices over USB HID using a vendor-specific protocol.

The Xbox One rumble packet specifies a duration for the effect. Chrome
always sets this to the maximum value and instead issues a new rumble
packet to end the effect. However, the duration of an Xbox One effect
with the maximum duration is approximately 3 seconds, causing longer
effects to end earlier than intended.

To support longer effects, the internal driver will now issue a second
rumble packet when needed.

Add a GamepadVibration runtime feature flag

In previous versions, the vibration feature was enabled with the
GamepadExtensions runtime feature flag. This CL splits the vibration
functionality into a separate flag that is enabled by default. This
allows the vibration feature to be enabled independently of other
features that use the same runtime flag.

Allow late initialization of gamepad haptics

Several fields of the blink::Gamepad object are only modified when
the device is first connected. This is done under the assumption that
these device properties cannot change while the device is connected.
However, in some cases we expose a gamepad to a page before we have
determined the haptic capabilities of the gamepad. Once the
capabilities are known, the gamepad object is updated but the new
value is not propagated. Instead, the page still sees the null value.

This changes the vibrationActuator caching behavior to allow a one-time
update from null to non-null after the gamepad is initially connected.

Comment 30 by a...@scirra.com, Jul 25 

I'm confused about the status of this - it looks like it just shipped enabled by default in Chrome 68, but as the gamepad.vibrationActuator property. However the MDN documentation and the spec (https://w3c.github.io/gamepad/extensions.html#partial-gamepad-interface) instead use an array at gamepad.hapticActuators. The feature was not listed on the release schedule (https://www.chromestatus.com/features/schedule), the platform status still indicates it's behind a flag (https://www.chromestatus.com/feature/5705158763741184), and this issue is not yet marked "fixed".

We'd like to implement code using this once it's released, but is it actually fully shipped now? It looks a bit like it got shipped accidentally...

Comment 31 by dannyyy5...@googlemail.com, Aug 27 

@mattreynolds I'd also very much like to know the current status of this.

I can confirm that it works and is enabled by default using Chrome M68+ so if this wasn't an accidental release, I'd really appreciate if this could be marked as "fixed" and mentioned in the upcoming Chrome M69 stable release.

Comment 32 by mattreynolds@chromium.org, Aug 27

Status: Fixed (was: Started)
This is intentionally enabled by the commit in #28, I forgot to update the chromestatus entry. Sorry for the confusion!

Comment 33 by dannyyy5...@googlemail.com, Aug 28 

Thanks a lot for the info and your work!

I'm sure that a lot of game developers will make use of this feature in their  HTML5 games.

Comment 34 by a...@scirra.com, Aug 29 

mattreynolds@ - thanks for clarifying. However how do we actually use the API? There is no accurate documentation anywhere. The spec describes a different API, MDN describes a different API, etc. I can't find documentation on how to use the API and what the parameters to playEffect() should be anywhere. Any tips?

Comment 35 by mattreyn...@google.com, Aug 29 

Here's the pull request on the github with the proposed spec changes but it hasn't been merged yet:

https://github.com/w3c/gamepad/pull/68/commits/8e65fbf6d84d70fbf11e504420b97e90c681ae72

canPlayEffectType is not yet implemented, but isn't very useful at this point anyway since there is only one effect type.

There's also a design doc with some examples:

https://docs.google.com/document/d/1jPKzVRNzzU4dUsvLpSXm1VXPQZ8FP-0lKMT-R_p-s6g/edit

And here are some interactive examples:

https://codepen.io/anon/pen/yKgYGz

I'll see if we can get better documentation on MDN.

Comment 36 by a...@scirra.com, Aug 29 

Great, thanks, looks like there's enough to get going with there.
