Haptic Design

Estimated reading: 3 minutes 1703 views

The Haptic Composer is a tool used in the process of haptic design. It is a graphical interface that allows for the manipulation of .haps files, which store the haptic experiences. It is also possible to edit the files manually, due to their human-readable format.

The Haptic Composer follows a familiar design interface of other design software, and its functionalities can be found in the tutorial section of the documentation.

Audio to Haptics encoding

The Haptic Composer also includes the ability to import a wav audio file and extract haptic properties automatically. Once imported, you can select which properties to extract by clicking on the audio representation.

Note Editing

The notes in the Composer can be edited precisely in the note editor by double-clicking on them. The properties that can be edited within the Haptic Composer include keyframes, which can be dragged and dropped on the design space, and the side properties indicate the value of the chosen keyframes. A right-click on the design space will allow adding a keyframe or transient.

Haptic Presets

The Haptic Composer also includes several pre-designed notes, called Haptic Presets, that can be assembled to quickly create haptic experiences. The preset can be edited in the note editor. To include a Haptic Preset, simply click on the preset category and drag and drop the preset name on a haptic melody.

Testing

Testing haptic effects can be done by sending them to the Interhaptics Player app, available for both iOS and Android. To use this feature, a free Razer ID is required (login and sign up detailed here).

Testing haptic effects can be done in the Haptic Composer app for PlayStation DualSense controllers / Razer Kraken V3 HyperSense DevKit.

Additionally, for other supported platforms, .haps files can be tested directly within the game engine via the Unity and Unreal SDK.
