Haptics in GameInput

​

Requirements

1. The device must be recognized as an audio source in Windows. The connection medium (USB, Bluetooth®, etc.) does not matter.
2. The device must expose no more than one haptic endpoint.
3. The device must expose no more than eight haptic locations.
4. The device must not modify its haptics capabilities after being connected.
5. The device must not have multiple audio endpoints with identical formats (bits per sample and samples per second).
6. The device must present the same container ID for its audio endpoint as the rest of the device.
7. The device must have a registry entry in to explicitly identify the haptic endpoint. The format is as follows:
   • Haptic devices are enumerated in the registry in HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\GameInput\Devices.
   • The specific device key is a combination of the vendor ID, product ID, usage page, and usage ID formatted as a hexadecimal string.
   • The HapticSamplesPerSecond is a DWORD value identifying the number of samples per second (Hz) of the haptic endpoint format.
   • The HapticsBitsPerSample is a DWORD value identifying the number of sample bits (sample size) of the haptic endpoint format.
   • The HapticLocations is a BYTE array of haptic location GUIDs. This array must contain between one and eight GUIDs, corresponding to the haptic channel mapping.
   To better illustrate this, consider the following sample device:

   Field	Value
   Vendor ID	0x045e
   Product ID	0x1234
   Usage page	0x0001
   Usage ID	0x0005
   Sample frequency	0x0fa0
   Sample size	0x0010
   Haptic locations	GAMEINPUT_HAPTIC_LOCATION_GRIP_LEFT, GAMEINPUT_HAPTIC_LOCATION_GRIP_RIGHT

   The associated haptic registry entry would look as follows:

    Windows Registry Editor Version 5.00

    [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\GameInput\Devices\045E123400010005]
    "HapticSamplesPerSecond"=dword:00000fa0
    "HapticBitsPerSample"=dword:00000010
    "HapticLocations"=hex:c2,07,c7,08,bb,66,6c,40,a8,4a,df,e0,85,12,0a,92,77,0b,5a,\
    15,b2,8b,db,40,86,90,b6,d4,11,26,df,c1
