Haptic Integration Software Comparison

A-Frame Haptics Component

The aframe-haptics-component is an A-Frame extension that enables integration of haptic feedback into WebXR applications with the Gamepad Haptics API. It provides a declarative interface for triggering controller vibrations in response to defined events, embedding tactile cues directly within A-Frame’s component architecture.

Key Features:

Actuator Selection (actuatorIndex): Specifies which actuator (the component of the controller that vibrates) in the gamepad's array of actuators to use for haptic feedback. Default is 0.
- - In practice, most VR controllers have only one actuator per controller (including Meta Quest 3 controllers), so (actuatorIndex:0) is the default and usually sufficient. But the option is there in case a device exposes more than one.
Duration (dur): Sets the length of the vibration pulse in milliseconds. Default is 100ms.
Enabled State (enabled): Determines whether the haptic feedback is active. Default is true
Event Listeners (events): An array of events that trigger the haptic feedback, such as triggerdown or triggerup. Default is an empty array []
Event Source (eventsFrom): Defines target entity from which to listen for the specified events, if different from the controller entity. Default is this.el.
Force (force): Controls the intensity of the vibration, ranging from 0 to 1. Default is 1.

Method:

pulse(force, duration): Manually triggers a vibration pulse with optional parameters for force and duration. If not specified, it defaults to the component's force and dur values.
Example usage:

this.el.components.haptics.pulse(); // Uses default force and duration

this.el.components.haptics.pulse(0.8, 550); // Custom force and duration

Installation:

Install via npm:

npm install aframe-haptics-component

Then require and use.

require('aframe');

require('aframe-haptics-component');

Include the component directly in your HTML (example):

<head>

<title>My A-Frame Scene</title>

</head>

<body>

<a-scene>

<a-entity hand-controls="left" haptics="events: triggerdown; dur: 5000; force: 0.5"></a-entity>

<a-entity hand-controls="right" haptics="events: triggerdown; dur: 100; force: 1.0"></a-entity>

</a-scene>

</body>

Pros/Cons for Development:

Pros:
- - Ease of Integration: Designed to work seamlessly with A-Frame, making it straightforward to add to existing projects.
  - WebXR Compatibility: Built to work with WebXR, meaning there no need for app installation. Allows for cross-platform deployment, and immediate access through any supported browser (easier for both developers and users of the app).
  - Low Learning Curve: A-Frame’s HTML-like syntax and modular component system make it accessible to developers without needing 3D or graphics experience. The haptics component fits naturally into this model, requiring minimal JavaScript.
  - Customizability (within bounds): While limited in scope, the component does allow control over vibration force, duration, and selection of specific actuators, giving developers a straightforward way to manage haptic feedback
Cons:
- - Browser and Device Support Variability: The component relies on the Gamepad Haptics API, which is still considered experimental and not uniformly supported across all browsers and hardware. Some controllers expose no haptic actuators via WebXR, and others may behave inconsistently.
  - No Maintenance Updates: The latest version (v1.6.3) was released four years ago, and there is no active maintenance or community-driven updates. A-Frame and WebXR have continued having updates since then, so there may be compatibility issues with some projects using this component.
  - Limited Documentation: While the component's README provides basic information, it lacks more comprehensive documentation and examples for more advanced implementations.
  - Limited Haptic Capabilities: The component only supports control of force and duration, which limits its usefulness on devices that support more advanced haptics (e.g., waveform patterns, frequency modulation). There is no native support for continuous vibration control, adaptive feedback, or rich tactile textures.

- 1. amplitude : The desired motor amplitude that should be within a [0-1] range.
  2. duration : The desired duration of the impulse in seconds.
  3. frequency : The desired frequency of the impulse in Hz. A value of 0 means to use the default frequency of the device.

SimpleHapticFeedback:

Component that responds to select and hover events by playing haptic impulses.
Allows configuration of haptic feedback for various interaction events such as Select Entered, Select Exited, Hover Entered, and Hover Exited.
Provides properties to set amplitude, duration, and frequency of the haptic impulse for each event.

HapticsUtility:

Provides utility methods for sending haptic impulses to controllers using static method calls.
Facilitates convenient triggering of haptic feedback without directly interacting with lower-level device APIs.

Pros/Cons for Development:

- - Integrated Workflow: Easily integrates with Unity's XR Interaction Toolkit, allowing developers to add haptic feedback without extensive customization. Simplifies the process of associating haptic feedback with common interaction events like selections and hovers.
  - Customizability: Offers control over amplitude, duration, and frequency of haptic impulses, enabling more tailored feedback experiences. (more variables to control than a-frame haptics component). Supports targeting specific haptic channels on devices for precise feedback delivery.
  - Event-Driven Feedback: Components like SimpleHapticFeedback allow for haptic responses tied to user interactions, enhancing user experience.
  - Regularly Updated: Up to date with Unity features, with documentation and a range of online videos for guidance in debugging and development
Cons:

Complexity in Advanced Scenarios: While the toolkit simplifies basic haptic integration, implementing complex haptic patterns or feedback synchronized with intricate interactions may require additional scripting and a deeper understanding of the underlying APIs.
Steeper Learning Curve: Integration with Unity features requires significant prior knowledge and familiarity with the platform's constantly updating settings, which may be unfeasible for some projects
No Built-In Support for Advanced Haptic Patterns: While more options for finer control exist, they provide only impulse-based haptics (amplitude, duration, and optionally frequency). There is s no out-of-the-box support for complex waveforms, dynamic modulation, or temporal patterns like ramping or rhythmic pulses.
