  • A responsiveness metric for controllable characters

    Creator:
    Oregon State University. Dept. of Computer Science, Srinivasan, Madhusudhanan, and Metoyer, Ronald A., 1971-
    Abstract:
    This paper presents an empirical approach for measuring and characterizing the responsiveness of a character to changes in goal. Our approach is based on keeping track of the character's progress towards a frequently changing goal. A "distance-to-goal" function is defined to measure the progress. We then calculate an asymptotic proportion...

  • Behavior graphs for data-driven animation of 3d characters

    Creator:
    Srinivasan, Madhusudhanan
    Abstract:
    In this dissertation, we present a user-in-the-loop method for the design of an interactive motion data structure that benefits from the advantages of both motion graphs and blend-based techniques. Our novel approach automatically analyzes a traditional motion graph built from labeled motion clips. The result is a more condensed, coarser...

  • Evolving character controllers for collision preparation

    Creator:
    Rose, Robert W.
    Abstract:
    Full dynamic control of physically simulated characters is the holy grail of video games and other interactive applications. Recent advances in the field have presented controllers that can handle the balance and fall response after a collision. This thesis addresses the development of a controller that handles the response before...

  • A data-driven model of pedestrian movement

    Creator:
    Casburn, Ledah
    Abstract:
    This thesis presents a model for simulating individual pedestrian motion based on empirical data. The model keeps track of a pedestrian’s position, orientation, and body configuration and leverages motion capture data to generate plausible motion. Our model can automatically incorporate a pedestrian’s physical limitations when making movement decisions, since it...

  • Interactive human locomotion using motion graphs and mobility maps

    Creator:
    Srinivasan, Madhusudhanan
    Abstract:
    Graph-based approaches for sequencing motion capture data have produced some of the most realistic and controllable character motion to date. Most previous graph-based approaches have employed a run-time global search to find paths through the motion graph that meet user-defined constraints such as a desired locomotion path. Such searches do...

  • Creating and editing motion machines for 3D characters

    Creator:
    Korada, Suman
    Abstract:
    Recent efforts in user-control of data-driven characters have focused on designing high-level graph data-structures that we call a Behavior Finite State Machine (BFSM). A BFSM is an interactive data-structure that benefits from the advantages of both motion graphs and blend-based techniques for generating animated motion. Each node in a BFSM...

  • Anticipating impacts

    Creator:
    Hermens, Benjamin J.
    Abstract:
    We present an approach for generating a character’s response in anticipation of an impending impact. Protective anticipatory movement is built upon several simple actions that have been identified as response mechanisms in monkeys and in humans. These actions are parameterized by a model of the interaction based on the approaching...

  • Studies to inform a visual language for authoring interactive exercise prescriptions

    Creator:
    Dodge, Jonathan E.
    Abstract:
    Communicating dynamic motion content, such as exercise, with a static medium, such as paper, is difficult. The technology exists for presenting 3D animated exercise content to patients; however, the tools for allowing exercise domain experts to effectively author the content do not exist. We conducted two formative studies with exercise...

  • The whats and hows of programmers' foraging diets

    Creator:
    Oregon State University. Dept. of Computer Science, Piorkowski, David, Fleming, Scott D., Kwan, Irwin, Burnett, Margaret, 1949-, Scaffidi, Chris, Bellamy, Rachel, and Jordhal, Joshua
    Abstract:
    One of the least studied areas of Information Foraging Theory is diet: the information foragers choose to seek. For example, do foragers choose solely based on cost, or do they stubbornly pursue certain diets regardless of cost? Do their debugging strategies vary with their diets? To investigate "what" and "how"...

  • Determining the validity of the task management environment to predict pilot concurrent task management performance

    Creator:
    Stebel, Jeffrey Michael
    Abstract:
    Concurrent Task Management (CTM) is the process by which human operators of complex systems (such as pilots, drivers, surgeons, and operators) allocate their attention among multiple concurrent tasks (Funk, 1991). A more thorough understanding of the human operator's knowledge, skills, and abilities associated with CTM might help us to prevent...
