What to consider when making your chatbot accessible.
Start by understanding how visitors to your chatbot interact with it;
- Some users have motor disabilities and have difficulty selecting some elements on your website with a mouse.
- Users with vision loss, low vision or colour blindness find it hard to use websites that are low in contrast.
Customise your chatbot to meet accessibility standards
Your chatbot can present any range of challenges for your visitors. You may want to consider screen readers and keyboard tab keys as navigation aids.
Visual cues or buttons which reveal chatbots are normally place bottom right of your screen. Consider how a screen reader or keyboard tab keys find or return to the chatbot. Think what it would be like for users who would have to tab through the entire web page each time. By adding skip to... links can help with some of these challenges.
Your users also need to know when a new element of a conversation is available on screen, like replies or redirects to web pages. Not just with sound or visually, screen readers need to be able to announce these events.
Consider colours for those with visual impairments and dyslexia.
In general you need strong contrasts for users with poor eyesight and slightly less contrast or colour combinations for those with dyslexia. There is a contrast range that works well for both.
Your chatbots scripts ideally will follow plain conversational speech patterns, avoiding jargon and acronyms. At the best of times jargon is difficult to understand and acronyms are certainly not understood by everyone.
If you can provide a feature on your website and chatbot that allows your users to change these combinations themselves then you can’t go too far wrong.
The ideal way to comply is to have your chatbot tested by a group of users with motor and cognitive disabilities, blindness and other forms of visual impairment.
