    • ALOHA: Adaptive Level of Detail for Human Animation: Towards and new Framework. 

      GIANG, THANH; MOONEY, ROBERT; PETERS, CHRISTOPHER; O'SULLIVAN, CAROL ANN (2000)
      The task of animating and rendering virtual humans in real-time is challenging. One must first establish a sense of realism through appearance, and then maintain this realism through correct and plausible motion, while ...

    • Attention-driven eye gaze and blinking for virtual humans 

      PETERS, CHRISTOPHER; O'SULLIVAN, CAROL ANN (ACM Press, 2003)

    • Bottom-up visual attention for virtual human animation 

      PETERS, CHRISTOPHER; O'SULLIVAN, CAROL ANN (IEEE Computer Society, 2003)
      We present a system for the automatic generation of bottom-up visual attention behaviours in virtual humans. Bottom-up attention refers to the way in which the environment solicits one?s attention without regard ...

    • Crowd and group simulation with levels of detail for geometry, motion and conversational behaviour 

      CASSELL, JUSTINE; VILHJALMSSON, HANNES; PETERS, CHRISTOPHER; LEESON, WILLIAM; GIANG, THANH; DINGLIANA, JOHN; DOBBYN, SIMON; O'SULLIVAN, CAROL ANN (2002)
      Work on levels of detail for human simulation has occurred mainly on a geometrical level, either by reducing the numbers of polygons representing a virtual human, or replacing them with a two-dimensional imposter. ...

    • Levels of detail for crowds and groups 

      CASSELL, JUSTINE; VILHJALMSSON, HANNES; DINGLIANA, JOHN; MACNAMEE, BRIAN; PETERS, CHRISTOPHER; GIANG, THANH; DOBBYN, SIMON; O'SULLIVAN, CAROL ANN (Blackwell, 2002)
      Work on levels of detail for human simulation has occurred mainly on a geometrical level, either by reducing the numbers of polygons representing a virtual human, or replacing them with a two-dimensional imposter. ...

    • A memory model for autonomous virtual humans 

      PETERS, CHRISTOPHER; O'SULLIVAN, CAROL ANN (2002)
      A memory model based on ?stage theory?, the dominant view of memory from the field of cognitive psychology, is presented for application to autonomous virtual humans. The virtual human senses external stimuli through a ...

    • New metrics for evaluation of collision detection techniques 

      LEVEY, EVIN; PETERS, CHRISTOPHER; O'SULLIVAN, CAROL ANN (2000)
      In this paper we describe new metrics for the evaluation of collision detection techniques. Through careful study of common applications of these techniques we have developed a series of comparative tests that should ...

    • Smart objects for attentive agents 

      PETERS, CHRISTOPHER; MCNAMEE, BRIAN; DOBBYN, SIMON; O'SULLIVAN, CAROL ANN (2003)
      We present an extended framework for modelling agent-object interactions in virtual environments. Our framework is based on the concept of Smart Objects and provides agents with pre-programmed interaction information for ...

    • Synthetic vision and memory for autonomous virtual humans 

      PETERS, CHRISTOPHER; O'SULLIVAN, CAROL ANN (Blackwell, 2002)
      A memory model based on ?stage theory?, an influential concept of memory from the field of cognitive psychology, is presented for application to autonomous virtual humans. The virtual human senses external stimuli through a ...

    • Vision-based reaching for autonomous virtual humans 

      PETERS, CHRISTOPHER; O'SULLIVAN, CAROL ANN (2002)
      A method for the generation of realistic real-time goal-directed virtual human arm motion is presented. Agents are endowed with a rudimentary synthetic vision and memory system that is used to gather and store data about ...
