One of the general themes in ubiquitous computing is the construction of devices and applications to support the automated capture of live experiences and the future access of those records. Over the past five years, our research group has developed over half a dozen different capture and access applications. In this paper, we present an overview of eight of these applications. We discuss the different design issues encountered while creating each of these applications and share our approaches to solving these issues (in comparison and in contrast with other work found in the literature). From these issues we define the large design space for automated capture and access. This design space may then serve as a point of reference for designers to extract the requirements for systems to be developed in the future.

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.
