On this page we explain, based on the Web Disability Simulator, how users with impairments can experience a website.
People with colour vision deficiency have difficulty distinguishing some or all colours. Total colour blindness (monochromatism / achromatopsia) is very rare. People with this visual impairment cannot perceive colours, but only different shades of grey.
People with colour vision deficiency have difficulty distinguishing some or all colours. Yellow-blue colour blindness (tritanopia) is rare. The name can be misleading. It is not the colours yellow and blue that are confused, but blue with green and yellow with violet.
People with colour vision deficiency have difficulty distinguishing some or all colours. Red-green colour blindness (protanopia and deuteranopia) is the most common form of colour blindness. It is more common in men than in women. People with red-green colour blindness have difficulty distinguishing the colours red, green, brown and orange.
Long-sightedness (hyperopia) is one of the most common forms of visual impairment.
People with hyperopia have difficulty focusing on objects at close range, making them appear blurred.
What is commonly called tunnel vision is the loss of peripheral vision. This can be due to a disease affecting the cells in the eye, but can also happen temporarily due to stress or depression.
Many people need to use their computer outside in bright sunshine. This can make it harder to see what is on the screen. Make sure there is sufficient contrast between the text and its background.
Parkinson's disease destroys the cells in the brain that produce dopamine, reducing the brain's ability to send signals. People with Parkinson's can suffer from symptoms such as tremors, stiff muscles and reduced mobility. The causes of Parkinson's disease are still unclear.
Dyslexia is a disability that makes it difficult for the brain to automate the interpretation of words. This makes it difficult for people with this disability to read and write. There is no connection between dyslexia, vision or intelligence. The causes of dyslexia are still unclear.
OpenDyslexic ist eine Schriftart, die speziell für legasthene Menschen entwickelt wurde. Manche legasthene Menschen haben Schwierigkeiten, die Richtung der Buchstaben zu unterscheiden oder es scheint ihnen, dass die Buchstaben nicht an ihrem Platz bleiben, sondern hin und her springen. In OpenDyslexic sind die Buchstaben unten etwas dicker.
Concentration can be difficult for anyone, but for some it can be a big problem in everyday life. Disabilities such as ADHD and autism can lead to difficulties in processing external stimuli, sorting information and sensitivity to sound.
The Web Disability Simulator helps you to better understand the importance of web accessibility by allowing you to experience how users with disabilities perceive a web page.
