  • Human Perception, Virtual Reality and the Built Environment
    2010 14th International Conference Information Visualisation, 2010
    Co-Authors: Angie Johnson, Emine M. Thompson, Kenny R Coventry
    Abstract:

    Recent research indicates that Virtual Reality (VR) as a communication tool to convey design intent and construction methodologies in the built environment sector has been utilized to varied degrees. Currently, the effectiveness of VR has been demonstrated from conception to the final stages of projects in many fields, yet its potential within the Built Environment has still to realised, despite a variety of successful demonstrations. There is concern that the current utilisation of VR compromises its full potential, unsurprisingly, as environmental representations focus predominantly on the visual modality, regardless of the multi sensory nature of the spatial experience. In addition, there is a distinct paucity of research exploring the complex interaction of environmental design and the user, such as the role of attention or conceptual interpretation. This paper aims to identify the issues concerning the utilization of VR models to aid communication for the Built Environment with specific reference to Human Perception issues.

  • A systems theoretical model for Human Perception in multimodal presence systems
    IEEE ASME Transactions on Mechatronics, 2001
    Co-Authors: P. Kammermeier, Martin Buss, Günther Schmidt
    Abstract:

    Advanced virtual environment and telepresence systems (here termed presence systems) are to display a continuous flow of information to the Human operator in several modalities of Human Perception. Such multimodal stimulation enhances the quality of the Human operator's interaction with the remote, or virtual environment. Dynamics and bilaterality in interaction between operator and environment complicate model-based display to the operator, particularly for the Human proximity (haptic) senses. In this paper it is shown how a mathematical model of the Human Perception process, in the terminology of systems theory, can contribute to convergence and progress in an interdisciplinary research held with regard to problem structuring, systematic planning and evaluation of experiments, and model-based generation of multimodal stimuli. The proposed systems theoretical framework describes the principles of Human Perception as a concatenation of nonlinear vector mappings. The efficacy and benefits of the presented theory are demonstrated by formal descriptions of sensory substitution experimental results found in the literature, and novel experiments performed in a virtual environment.

  • Rate-distortion theory and Human Perception
    Cognition, 2016
    Co-Authors: Chris R. Sims
    Abstract:

    The fundamental goal of Perception is to aid in the achievement of behavioral objectives. This requires extracting and communicating useful information from noisy and uncertain sensory signals. At the same time, given the complexity of sensory information and the limitations of biological information processing, it is necessary that some information must be lost or discarded in the act of Perception. Under these circumstances, what constitutes an 'optimal' perceptual system? This paper describes the mathematical framework of rate-distortion theory as the optimal solution to the problem of minimizing the costs of perceptual error subject to strong constraints on the ability to communicate or transmit information. Rate-distortion theory offers a general and principled theoretical framework for developing computational-level models of Human Perception (Marr, 1982). Models developed in this framework are capable of producing quantitatively precise explanations for Human perceptual performance, while yielding new insights regarding the nature and goals of Perception. This paper demonstrates the application of rate-distortion theory to two benchmark domains where capacity limits are especially salient in Human Perception: discrete categorization of stimuli (also known as absolute identification) and visual working memory. A software package written for the R statistical programming language is described that aids in the development of models based on rate-distortion theory.
