Interhaptics is a cross-platform tool.

The Interhaptics SDK powered by the Interhaptics Engine allows the developer to deploy haptic experiences onto multiple devices. Each device has their own haptic capabilities as described in the table below.

Device/Platform	Haptic Perception supported	Rendering Strategy
iPhone (Core Haptics Engine - iPhone 8 or newer)	Vibration	Transients and 1 haptic melody averaging all haptic effects melodies both in frequency and amplitude. Frequency is translated into sharpness.
	Texture	1 haptic melody averaging all haptic effects melodies both in frequency and amplitude. Frequency is translated into sharpness.
	Stiffness	Modulation of the vibration strength in function of the stiffness value. Sharpness is set at 0.5.
Android Phone (Android APIs 26 and higher) with Amplitude Control	Vibration	Transients and 1 haptic melody adding all haptic effect amplitudes.
	Texture	1 haptic melody adding all haptic effect amplitudes.
Android Phone (Android APIs 26 and higher) without Amplitude Control*	Vibration	Similar to Android with Amplitude Control, check here for threshold usage.
	Texture	Similar to Android with Amplitude Control, check here for threshold usage.
Meta Quest (OVR APIs)	Vibration	Transients and 1 haptic melody adding all haptic effect amplitudes.
	Texture	1 haptic melody adding all haptic effect amplitudes
	Stiffness	Modulation of the vibration strength in function of the stiffness value.
DualSense™ wireless controller for PlayStation®5	Vibration	Full wideband haptic signal.
	Texture	Full wideband haptic signal.
	Stiffness	10 points of the stiffness function following device specifications.
XInput controller	Vibration	Transients and 1 haptic melody adding all haptic effect amplitudes.
	Texture	1 haptic melody adding all haptic effect amplitudes
	Stiffness	Modulation of the vibration strength in function of the stiffness value.
OpenXR headset (controllers)	Vibration	Transients and 1 haptic melody adding all haptic effect amplitudes.
	Texture	1 haptic melody adding all haptic effect amplitudes
	Stiffness	Modulation of the vibration strength in function of the stiffness value.

*For Android devices without Amplitude Control capability, is it worth mentioning that rendering will greatly differ compared to Android devices with this capability. For more information, please refer to the Mobile SDK Setup section
