Introduction

With all devices now touch-driven and offering few physical keys, the effective usage of touch screens is critical. The chapter, “Touchscreen-Based User Interaction,” by Andrea Bizzotto, provides basic insight into the complexities and solutions required to achieve the best possible user-interaction and experience through a touch-based interface.

“Optimizing a 3D UI Engine for Mobile Devices,” by Hyunwoo Ki, offers early insights into optimizing a user interface for mobile devices, looking at the importance of font rendering engines and “dirty region”-based optimizations to avoid rendering more than is actually required.

The chapter, “A Shader-Based eBook Renderer," by Andrea Bizzotto illustrates a vertex-shader-based implementation of the page-peeling effect of a basic eBook renderer. It covers high-quality procedural antialiasing of the page edges, as well a...
