‘Concurrent Input Mechanisms’ requires no restrictions on modes of input.


Users may choose to switch between different methods of input when interacting with a website. For example, for some controls a user might prefer to input by keyboard and for others they might favour a mouse.

Users might also prefer to override the primary input mechanism for a device. For example, connecting an external keyboard to a touchscreen tablet. Allowing users to switch between concurrent input mechanisms can satisfy these needs.

How to Pass ‘Concurrent Input Mechanisms’

Ensure there are no restrictions on modes of input. 

Exceptions to ‘Concurrent Input Mechanisms’

  • Where a set input mode is essential. For example, a touch-typing test.
  • If the restriction is required for security.
  • If the restriction is required to respect a user’s setting.
