Success Criterion 2.5.6 Concurrent Input Mechanisms *

Understanding Success Criterion: 

Web content does not restrict use of input modalities available on a platform except where the restriction is essential, required to ensure the security of the content, or required to respect user settings.

Accessibility Level: 
AAA
Intent of Success Criterion: 

The intent of this Success Criterion is to ensure that people can use and switch between different modes of input when interacting with web content. Users may employ a variety of input mechanisms when interacting with web content. These may be a combination of mechanisms such as a keyboard or keyboard-like interfaces and pointer devices like a mouse, stylus or touchscreen.
Even though a device may have a primary input mechanism, the user may choose to employ alternative input mechanisms when interacting with the device. For example, the primary mechanism for mobile phones and tablets is the touchscreen. The user of these devices may choose to use a paired mouse or external keyboard as an alternative to using the touchscreen.
Users should be able to switch input mechanisms at any point should the user determine that certain tasks and interactions are more easily accomplished by using an alternative input mechanism. Content must not limit the user's interaction to any particular input mechanism unless the restriction is essential, or is required to ensure the security of the content or to respect user settings.

Specific Benefits of Success Criterion: 

• Users can interact with web content with whichever input mechanism is preferred and available to them.
• Users may switch between input mechanisms when they desire or the circumstances require it.
• Users are allowed to add and remove input mechanisms at any point, where supported by the operating system.
