Since it’s inception, the user interface design of DAKboard has centered around two key design principles: minimalism and distance legibility.
Minimalism is conveying our message (ie. the time, or an event) as simply as possible with the fewest user interface elements as possible. And distance legibility is arranging and sizing the user interface elements such that they’re visible and legible at the appropriate distances.
While DAKboard will look great on any display, it was really designed for our 23 inch Wall Display. With this size display, we utilized distance legibility rules so that various user interface elements are visible at different distances. For example, we wanted the time and current weather to be visible from across the room, which is why they’re the largest elements. Lets break down each distance group and the elements in them.
Distance: 20+ feet / 10 meters
This distance is looking at DAKboard from another room (or from across a large room), or down the hall. The very basic features of DAKboard should be visible and legible: time and current weather, and of course the background photo:
Distance: 10 feet / 3 meters
A distance of 10 feet is standing in the same room as DAKboard. Events and the extended forecast should now be legible. In addition to the event title, the hour the event starts should also be legible. Note that at this distance, we can’t easily read the minutes or AM/PM (that comes next!).
Distance: 5 feet / 2 meters
We’ve seen the time, forecast and events from afar and now want to know a little more about the event. At 5 feet, the event minutes and AM/PM become easily visible:
Distance: 2 feet / 0.5 meters
And finally, at 2 feet we can see the smallest level of text that states the weather service being used, and the last update time:
Other Display Sizes
If you’re not using our 23 inch Wall Display, that’s ok! These rules still apply for displays of all sizes, however the distance break points will shrink or expand. For example, if you’re running DAKboard on a 10 inch tablet, the largest text now is only visible up to about 10 feet.
