Talk Abstract:
One of the biggest challenges in current and future application development is device heterogeneity. Nowadays, we are seeing a rich variety of mobile computing devices that can run applications, such as Notebook PCs, PDAs, smart phones, car navigation systems, etc. These devices have different capabilities in processors, memory, networking, screen sizes, input methods, and software libraries. We also see that users own many types of devices. Depending on their changing situations and environments, users may choose to switch from one type of device to another that brings the best combination of application functionality and device mobility (size, weight, etc.). In this talk, I will present an application framework called the Roam system. The Roam system can assist application developers to build multi-platform applications capable of running on heterogeneous devices, and allow users to move/migrate a running application among heterogeneous devices in an effortless manner.
