  • Accessibility — The fundamental issue regarding accessibility is that everyone should have access to the services provided by ICT, e.g. computer programs, Email and the World Wide Web, regardless of any visual, auditory, or other physical impairment they might have. Assistive Technology may be employed to increase access to such services, e.g. Text To Speech (TTS) screen readers, screen magnifiers, speech recognition systems, hearing assistance devices, etc. Designers of computer programs and websites need to take account of accessibility when choosing colours, fonts and font sizes, etc: see Font. See Section 4, Module 3.5 regarding speech technologies and how they may help unsighted and partially sighted computer users and people with hearing impairments. See SENDA. See Section 6.3.1, Module 3.3, headed HTML Validators, regarding website accessiblity.
