Automated support for the capture and access of live experiences is a common theme for ubiquitous computing. For certain capture situations, such as informatl or opportunistic gatherings, existing capture framesworks are inadequate for a number of reasons. They require too much time to initiate a capture session and they often are too inflexible to support unstructured and impromptu use. In this paper, we present a whiteboard capture application called DUMMBO, aimed to support opportunistic and serendipitous meeting capture. We emphasize an easy-to-initiate interface that mirrors as much as possible traditional whiteboard functionality. This is accompanied by visualization techniques for accessing captured meetings afterwards. By separating the physical interface for capture from the electronic interface for accessing captured meetings, we demonstrate how a capture and access application can be designed to better support its intended audience.

We present a new user interface technique for the visualization and playback of long media streams decorated with significant events. Our Multi-Scale Timeline Slider allows users to precisely focus on a specific location in a very long media stream or set of streams based on significant events while also retaining the stream's entire context.

A common focus shared by researchers in mobile, ubiquitous and wearable computing is the attempt to break away from the traditional desktop computing paradigm. Computational services need to become as mobile as their users. Whether that service mobility is achieved by equipping the user with computational power or by instrumenting the environment, all services need to be extended to take advantage of the constantly changing context in which they are accessed. This paper will report on work done in the Future Computing Environments Group at Georgia Tech to provide infrastructure for context-aware computing. We will describe some of the fundamental issues involved in context-aware computing, solutions we have generated to provide a flexible infrastructure and several applications that take advantage of context awareness to allow freedom from traditional desktop computing.
