There is a lot of low hanging fruit ripe for the picking within the inclusive design realm. So in 2017 what fruit do i think is the ripest?
Dark mode. This one feature alone implemented OS wide could make a huge difference to a substantial user base Not only would it solve a problem for the visually impaired for whom contrast is a major issue, but those with situational requirements where dark mode makes the most sense. Think late at night in bed, that white screen just makes your eyes ache.
So will there be an appetite for this in 2017? My gut says yes. If rumours hold true and the iPhone moves to an AMOLED display, we will see an introduction of dark mode. This will have a wonderful knock on affect of influencing design direction for a while. So not only we will see dark mode introduced at the OS level, but we will start to see a whole host of apps fall in line.
