In relation to the accessibility of lifts, lack of awareness regarding the importance of measures that allow people with a visual impairment to use lifts autonomously is a big problem. While it is broadly understood and accepted that certain specific requirements such as access without steps, a minimum door width or enough space inside the lift car are necessary requirements, it is not yet widely accepted that, for example, the usability of control devices is just as necessary to ensure the accessibility of the whole lift. Therefore, people with visual impairment often experience serious difficulties in using lifts.
