I was frequently called upon to help determine how to adapt the UI strategic design to several unanticipated display sizes.
One of the main goals of the user-interface design group was coherence. The same design had to be scaled to fit anything from the largest full-screen displays to the smallest quarter-panel devices. This had to be done while maintaining the a usable touch-target size and readable font size. This allows a coherent user-experience across all level of devices.
Shown are large 4:3 aspect ratio display (both 10-inch and 8-inch), 7-inch 16:9 aspect ratio displays, half-panel and quarter-panel touch displays. All displays met the requirements for touch-target size and font readability.The UI architecture is similar to allow transfer of learning and a common user experience.
