Concurrent Input Mechanisms (2.5.6 – Level AAA)

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

Introduction

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.
