  • authoring viewing and generating hypervideo an overview of hyper Hitchcock
    ACM Transactions on Multimedia Computing Communications and Applications, 2008
    Co-Authors: Frank M Shipman, Andreas Girgensohn, Lynn D Wilcox
    Abstract:

    Hyper-Hitchcock consists of three components for creating and viewing a form of interactive video called detail-on-demand video: a hypervideo editor, a hypervideo player, and algorithms for automatically generating hypervideo summaries. Detail-on-demand video is a form of hypervideo that supports one hyperlink at a time for navigating between video sequences. The Hyper-Hitchcock editor enables authoring of detail-on-demand video without programming and uses video processing to aid in the authoring process. The Hyper-Hitchcock player uses labels and keyframes to support navigation through and back hyperlinks. Hyper-Hitchcock includes techniques for automatically generating hypervideo summaries of one or more videos that take the form of multiple linear summaries of different lengths with links from the shorter to the longer summaries. User studies on authoring and viewing provided insight into the various roles of links in hypervideo and found that player interface design greatly affects people's understanding of hypervideo structure and the video they access.

  • hypervideo expression experiences with hyper Hitchcock
    ACM Conference on Hypertext, 2005
    Co-Authors: Frank M Shipman, Andreas Girgensohn, Lynn D Wilcox
    Abstract:

    Hyper-Hitchcock is a hypervideo editor enabling the direct manipulation authoring of a particular form of hypervideo called "detail-on-demand video." This form of hypervideo allows a single link out of the currently playing video to provide more details on the content currently being presented. A workspace is used to select, group, and arrange video clips into several linear sequences. Navigational links placed between the video elements are assigned labels and return behaviors appropriate to the goals of the hypervideo and the role of the destination video. Hyper-Hitchcock was used by students in a Computers and New Media class to author hypervideos on a variety of topics. The produced hypervideos provide examples of hypervideo structures and the link properties and behaviors needed to support them. Feedback from students identified additional link behaviors and features required to support new hypervideo genres. This feedback is valuable for the redesign of Hyper-Hitchcock and the design of hypervideo editors in general.

  • hyper Hitchcock authoring interactive videos and generating interactive summaries
    ACM Multimedia, 2003
    Co-Authors: Andreas Girgensohn, Frank M Shipman, Lynn D Wilcox
    Abstract:

    To simplify the process of editing interactive video, we developed the concept of "detail-on-demand" video as a subset of general hypervideo. Detail-on-demand video keeps the authoring and viewing interfaces relatively simple while supporting a wide range of interactive video applications. Our editor, Hyper-Hitchcock, provides a direct manipulation environment in which authors can combine video clips and place hyperlinks between them. To summarize a video, Hyper-Hitchcock can also automatically generate a hypervideo composed of multiple video summary levels and navigational links between these summaries and the original video. Viewers may interactively select the amount of detail they see, access more detailed summaries, and navigate to the source video through the summary.

  • combining spatial and navigational structure in the hyper Hitchcock hypervideo editor
    ACM Conference on Hypertext, 2003
    Co-Authors: Frank M Shipman, Andreas Girgensohn, Lynn D Wilcox
    Abstract:

    Existing hypertext systems have emphasized either the navigational or spatial expression of relationships between objects. We are exploring the combination of these modes of expression in Hyper-Hitchcock, a hypervideo editor. Hyper-Hitchcock supports a form of hypervideo called "detail-on-demand video" due to its applicability to situations where viewers need to take a link to view more details on the content currently being presented. Authors of detail-on-demand video select, group, and spatially arrange video clips into linear sequences in a two-dimensional workspace. Hyper-Hitchcock uses a simple spatial parser to determine the temporal order of selected video clips. Authors add navigational links between the elements in those sequences. This combination of navigational and spatial hypertext modes of expression separates the clip sequence from the navigational structure of the hypervideo. Such a combination can be useful in cases where multiple forms of inter-object relationships must be expressed on the same content.

  • hyper Hitchcock towards the easy authoring of interactive video
    International Conference on Human-Computer Interaction, 2003
    Co-Authors: Frank M Shipman, Andreas Girgensohn, Lynn D Wilcox
    Abstract:

    To simplify the process of editing interactive video, we developed the concept of “detail-on-demand” video as a subset of general hypervideo where a single button press reveals additional information about the current video sequence. Detail-on-demand video keeps the authoring and viewing interfaces relatively simple while supporting a wide range of interactive video applications. Our editor, Hyper-Hitchcock, builds on prior work on automatic analysis to find the best quality video clips. It introduces video composites as an abstraction for grouping and manipulating sets of video clips. Navigational links can be created between any two video clips or composites. Such links offer a variety of return behaviors for when the linked video is completed that can be tailored to different materials. Initial impressions from a pilot study indicate that Hyper-Hitchcock is easy to learn although the behavior of links is not immediately intuitive for all users.

  • dartmouth Hitchcock medical center spine care tn
    Social Science Research Network, 2009
    Co-Authors: Robert S Huckman, Michael E Porter, Rachel Gordon, Natalie Kindred
    Abstract:

    Describes the Spine Center at Dartmouth-Hitchcock Medical Center, a multidisciplinary unit that offers patients suffering from spinal problems 'one-stop' access to a range of providers including orthopedic surgeons, neurosurgeons, neurologists, medical specialists in physical medicine and pain management, mental health providers, and occupational and physical therapists. The Center was created to address what its founder, James Weinstein, M.D., saw as the uncoordinated and inefficient delivery of spinal care in the United States. The Center emphasized using non-surgical treatments (e.g., physical therapy and exercise, behavioral modification, pain-relieving drugs) as either a complement to, or substitute for, surgical procedures, and patients were actively engaged in the process of determining what type of care to pursue. In addition, Weinstein and his staff collected data from the Center's clinical practice to conduct academic research on the outcomes and cost-effectiveness of various approaches to treatment. The case allows for a critical analysis of the Spine Center's unique approach to care delivery and provides an opportunity to examine the applicability of this model in other clinical areas.

  • a clinical pathway for guardianship at dartmouth Hitchcock medical center
    The Joint Commission Journal on Quality and Patient Safety, 2014
    Co-Authors: Jasper J Chen, Michele A Blanchard, Christine T Finn, Margaret L Plunkett, Karen Homa, Debra A Fournier, James F Gregoire, Miranda M Handley, Elizabeth A Stedina
    Abstract:

    Article-at-a-Glance Background Guardianship may be necessary when inpatients lack medical decision-making capacity and are unwilling to go home to be cared for by interested proxy decision makers. Interventions, centered on a clinical pathway, were conducted at Dartmouth-Hitchcock Medical Center (DHMC; Lebanon, New Hampshire). Because guardianship occurs at the interface of clinical care and governmental bureaucracy, quality improvement efforts focused on "in-hospital" processes, while actions were taken to improve communication between clinical teams and the legal system. Methods A multidisciplinary quality improvement team mapped the DHMC guardianship process and analyzed the causes for delays before creating the clinical pathway. Specific interventions were designed and implemented to address the identified improvement areas. Results For the 26 guardianship patients during a two-year period (May 1, 2011–May 1, 2013), the charges incurred totaled approximately $4,000,000—for an average of more than $150,000 per patient. The medically unnecessary days of their length of hospital stay decreased from an average of 27.8 to 11.3, a statistically significant result as demonstrated by statistical process control analysis. The shorter hospitalizations of the last 13 patients amounted to 214.5 medically unnecessary hospital days saved and more than $1.2 million in charges reduced during the two-year period. Conclusions Guardianship is a complex process that generates significant delays in appropriate care and increases in charges. The redesigned, standardized guardianship process, as defined in the clinical pathway, reduced associated medically unnecessary days of hospitalization.
