Xbox Accessibility Guideline 110: Haptic feedback

  • Artículo

Goal

The goal of this Xbox Accessibility Guideline (XAG) is to ensure that players can configure haptic feedback settings for their controller. This addresses the needs of a wide range of players. They include players who benefit from haptic feedback as an additional output modality and players who prefer to disable haptic feedback due to discomfort or pain that this feedback might elicit.

Overview

Haptic feedback is enjoyed by many players because of its ability to provide a more immersive gaming experience. The use of in-game haptics as an additional way of providing informational cues also benefits players who aren't able see visual cues or hear audio cues.

For some players, it's important to note that haptic feedback can be bothersome, distracting, or even painful. Players with sensory processing disorders might interpret haptic feedback more intensely than others and want to turn it off. Similarly, players with chronic pain conditions might experience pain or discomfort as a result of haptics. This is why it's important to provide players the option to configure their own haptic settings. This includes the option to turn haptics on or off, depending on player preferences, and the option to configure the haptic vibration intensity across a spectrum for players who use haptic cues but can only tolerate them at a lower intensity than the default.

It's also important to note that haptic feedback isn't supported by all platforms or devices such as PC mice and the Xbox Adaptive Controller. Therefore, conveying in-game cues or other important information should be supported through a combination of outputs in addition to haptic feedback. This ensures that players who are using adaptive devices that don't have haptic motors, and those who disable haptic feedback, don't miss any key information.

Scoping questions

Does your game support haptic feedback to provide information? If so:

  • Can players disable haptic feedback entirely?

  • Can players adjust the intensity of haptic feedback?

  • Does your game use haptic feedback alone to convey any information?

    • If yes, additional methods of conveying information should be used to ensure that players who have haptic feedback disabled or are using devices that don't support haptic capabilities don't miss any key information.

Implementation guidelines

  • If haptic feedback is a supported feature, players should have the ability to:

    • Turn off the feedback.

    • Adjust the strength of the feedback.

      Example (expandable)

      A screenshot from the Sea of Thieves Game Options menu. The "Accessibility Settings" tab is selected. The controller focus is currently on the "Controller Vibration Intensity" option slider. Its current value is set to 49 out of 100.

      A screenshot from the Ori and the Will of the Wisps Settings menu. The Vibration setting has focus. The slider's current value visually appears to be set to about 75 percent intensity.

      In Sea of Thieves and Ori and the Will of the Wisps, players can adjust the intensity of haptic controller vibrations across a wide spectrum from no vibration to the highest intensity vibration available.

    • Use other means of feedback. Haptic feedback shouldn't be the only method of conveying information. It should be accompanied by visual and auditory indicators.

      Example (expandable)

      A screenshot from the Grounded gameplay environment.

      In this example from Grounded, haptic cues are given in addition to audio and visual cues. Players can choose to enable haptic feedback. However, because Grounded also provides ample audio and visual cues to represent the same information, players won't miss any key information if they decide to disable haptics.

  • Consider adding haptic cues as an optional, additional channel for important visual or audio information.
