One thought "design pattern" I pay attention to is respecting multiple modes. For example, language learning tends to focus on single-phase progress. In practice, a tourist such as myself, bad at many languages, will study before a trip and hope it all comes together during the trip. One realistically doesn't continue studying during a trip, but one's mind shortens available connections to develop a working facility. This favors committing a radio play to memory, over the staggered recall patterns of single-phase language study. Von Neumann could recall entire books, but in sequence. That's key. For keyboards, the most novel designs are better at intense coding sessions, but worse at hunt-and-peck finding an arrow key, or muting one's computer in the middle of the night before the dog wakes everyone up. For me, the middle "tap/hold" zone of my Leopold FC660C is perfect for long coding and typing sessions, while the periphery does a great job of supporting casual use.
