ShareBook: An Application of Cross-Platform E-Book Viewer with Vector Graphic

Many handheld devices have been developed in the mobile industry. Most mobile devices in the market are carried Android operating system. Android also supports many other hardware components that increase mobile devices functionality. The operating system can be used for multimedia, touch screen, number of types of sensors and 2D/3D graphics. Due to open source license, many manufactures integrate their own production to Android system. Hence, this paper proposed a ShareBook software based on Android system. ShareBook integrates new types of sensor such as touch sensor, bending sensor and gyroscope to develop a flexible display platform with Android operating system. These sensors change user’s operation in general smart mobile devices with Android. Flexible displays bring great difference in interaction behavior between system software and end user. However, there are some other problems in traditional E-Book application. Size of screen on mobile devices is the first problem. Hardware manufactures produce 4-5 inches display on their mobile phone production, the display size is at most 10.1 inches on pad production. Some people hardly read contents on small size screen. So, ShareBook can easily transfer e-book viewer to larger size display such as TV or LCD display when user can reach the larger size display in their environment. Second problem is application’s performance efficiency. ShareBook integrates vector graphic library into Android and optimizes the performance of vector graphic library by Renderscript and GPGPU. ShareBook also combines cloud platform resource for image file transformation and storage resource extension.
