1. Deference. icons simplify and clarify ornamentation
Clarity. Text is legible at every size, icons are precise and lucid, adornments are subtle and appropriate, and a sharpened focus on functionality motivates the design.
Depth. Visual layers and realistic motion impart vitality and heighten people’s delight and understanding.
The UI helps people understand and interact with the content, but never competes with it. For my understanding, as an interactive designer, our target of interface design can be also seen as to design a visual system or communication language between user and content. Through reading the rules of HIG design, I deeply thinking about why we choose icons simplify and clarify ornamentation in iOS system. And how to using design for helping people get the content, but not confuse them. The interface’s exist is servicing for user experience. That’s why as a UI designer our target is highlight the users to get content at first. And putting your personal design style as second place.
2. Continue thinking of how to make the most important content and functionality clear and easy to interact with. The IOS design system use plenty of negative space, let color simplify the UI, ensure legibility by using the system fonts and embrace borderless buttons. These details are telling us each single gesture design were creating through users perspective.
3. Another interesting point for me is about the iOS app includes a window. But—unlike a window in a computer app—an iOS window has no visible parts and it can’t be moved to another location on the display. Most iOS apps contain only one window; apps that support an external display can have more than one. Because users tend to experience an iOS app as a collection of screens. From this perspective, a screen generally corresponds to a distinct visual state or mode in an app. Through this point, I continue explore the object is becoming more important which is UIScreen design.
