The intense popularity of touchscreen devices is nothing new to us—the web/mobile designers and developers. So we're not going to talk about market shares, statistics, or analytics numbers. Instead, we're going to talk about the things we need to consider to build a usable interface, such as target sizes, navigation patterns, navigation icons, best practices and mobile device ergonomics.
In this chapter, we're going to cover the following topics:
The ideal target sizes on small UIs.
The posture patterns and the touch zones.
The basic guidelines to consider for RWD.
The navigation patterns for RWD.
