“A new class of mobile service is emerging called engaging mobile experiences. Engaging mobile experiences put the user experience first. As a result, these experiences prioritize usability, offer new services and deliver content instantaneously. But much more importantly, they build a powerful affinity with the user. They promise experiences that are expressive, memorable, and much more desirable. The design of these engaging mobile experiences requires a special touch as they are developed for the small screen. We believe these guiding principles are critical in defining this new class of experience.”
