- Physical approach - For stationary or installed systems, people may need an accessible path of approach that fits them and any assistive technology they use use (such as mobility devices).
- Private data entry - For systems that collect private information, people need positive assurance that sensitive information they enter, such as password or national ID, is not displayed on the screen.
- Programmatic structure and relationships - For systems that present content, people may need structure and relationships (title, labels, section headings) presented sensorily and programmatically.
- Room for use - For stationary or installed systems, people may need adequate room to approach a device that fits them and any assistive technology they use (such as mobility devices).
- Separate output control - For systems with assistive technology built into the platform or that work with assistive technology, people may need to be able to control output of assistive technology separate from output of content.
