Interacting Devices, Applications, and Users In a Pervasive Computing World

In the future, we foresee the emergence of a pervasive computing world in which every device is internetworked via ubiquitous wireless and wired communication links to interact with every other device, e.g. Bluetooth-enabled personal digital assistants, video-enabled mobile phones, wearable computers, appliances, kiosks, toys, and sensors. Such interaction will occur both between devices in close proximity as well as between devices and remote applications and services distributed on the Internet and Web.

A first step towards enabling pervasive computing is facilitating interactive access to remote multimedia and the Web's content from a single user's wireless handheld client. I will discuss how my research on adaptive transcoding of Web content has helped to mitigate this problem. Looking beyond single-device wireless Web access, my recent work on the "WebSplitter" concept has expanded the role of multi-device proximity-based pervasive computing. WebSplitter's novelty resides in its ability to create multiple partial views by filtering XML content based both on what a user is authorized to receive and on what nearby devices are capable of receiving. A wireless PDA would leverage a WebSplitter service to remotely control multiple nearby devices. My talk will conclude with a discussion of my future research interests in the areas of multi-device proximity-based pervasive computing and distributed Internet computing.
