> However one thing he also says is: don't assume that low-vision is the only type of disability. You also need to build software for people who are: deaf, have slow motor skills (e.g. avoid putting strict time limits on user actions, or making things jump around on the screen too much while people are trying to hit a target), lack fine motor skills (e.g. don't make a target too small), etc. These are also good UX guidelines in general.
