Description

This document specifies the design and specification of on-screen keyboards (keyboards that are displayed on a screen) with direct touch interface, including those with some audio feedbacks.

This document specifies keyboard layouts designed for on-screen keyboards with direct touch interface and ways for interaction with them, and proposes a new framework including requirements and recommendations.

It does not cover virtual keyboards that are not displayed on a screen, and on-screen keyboards that do not provide a direct touchscreen interface such as on-screen keyboards relying on an accessory unit like a trackpad or a remote control for interactions with the user.

It does not apply to physical keyboards that use real or adaptable keys, which can be customised to user needs, for example with LCD display.
