Mobile applications continue to proliferate. But the quality of mobile user experiences ranges from pathetic to pure joy. You can develop an app for the iconic Apple iPhone that has horrible usability. Likewise, you can develop an app for Windows Phone 7 that seems to read your mind. If you think mobile user experience design is about choosing the best development tools and designing for a smaller screen size, guess again. Sure, the platform is important, but great mobile user experiences don’t happen just because you chose the best development tools. To deliver apps your users will love, you must design a user experience that is useful, usable, and desirable and that takes into account the five dimensions of the mobile context: location, locomotion, immediacy, intimacy, and device. User experience design is the differentiator. Great mobile apps are the result. This report shows you how.
