    Enabling the Generation, Preservation & Use of Records and Memories of Everyday Life
    (Georgia Institute of Technology, 2002) Truong, Khai Nhut ; Abowd, Gregory D.
    Our daily lives provide us with a great deal of records and memories that we want to access at some point in the future. As a result, we often spend our time and effort trying to preserve much of these experiences. To assist in the process, automated capture and access applications attempt to relieve humans of the burden of manually documenting these experiences. To allow application developers to build such applications more easily, we have developed INCA, an infrastructure for capture and access applications. In this paper, we show how this infrastructure can facilitate the construction of these applications, and demonstrate its use through the development of three sample applications.

    Vicariously Sharing Captured Web Experiences through an Automated Recommendation System
    (Georgia Institute of Technology, 2002) Truong, Khai Nhut ; Abowd, Gregory D. ; Pimentel, Maria da Graca Campos
    Our daily experiences are rich in content that we want to recall in the future. These previous experiences are often where we begin in our search for information needed when we work. In a community, we can rely on others to suggest materials when our own expertise fails to provide us with what we need. Likewise, others will make referrals only from things that they have previously experienced. In this paper, we present WebMemex, a system that recommends related Web pages to what the user is currently viewing. This system acts as an instantiation of an architecture to automatically capture and access information in a manner similar to when a person is searching for information related to her current work context where the related information being retrieved is something she has previously seen or that her friends have seen before and could ultimately suggest to her.

    Who, What, When, Where, How: Design Issues of Capture and Access Applications
    (Georgia Institute of Technology, 2001) Truong, Khai Nhut ; Abowd, Gregory D. ; Brotherton, Jason Alan
    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.

    Supporting Capture and Access Interfaces for Informal and Opportunistic Meetings
    (Georgia Institute of Technology, 1999) Brotherton, Jason Alan ; Abowd, Gregory D. ; Truong, Khai Nhut
    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.

    A Multi-Scale Timeline Slider for Stream Visualization and Control
    (Georgia Institute of Technology, 1999) Richter, Heather Anne ; Brotherton, Jason Alan ; Abowd, Gregory D. ; Truong, Khai Nhut
    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.
