• PROFILE

    Nami OGAWA is currently pursuing her Ph.D. in Engineering under the supervision of Prof. Michitaka HIROSE at the University of Tokyo in Japan.

    Her research fields are mainly virtual reality (VR) and perceptual psychology.

    Based on psychological theory, especially well-known illusions, she tries to develop ingenious displays and artworks that evoke artificial novel sensations and experiences.

    At the same time, she utilizes VR as an experimental tool to investigate human perception.

    She is interested in body ownership and cross-modal perception.

     

    KEYWORDS: virtual reality, body ownership, embodied perception, rubber hand illusion, body-based scaling, cross-modal

    Metamorphosis Hand [video]

    "Metamorphosis Hand" is a work that provides an experience of having an augmented body by enabling to play the piano with virtual hands whose shape, especially finger lengths, and movement are transforming dynamically.

    From a psychological point of view, this system is a tool for investigating "Body Ownership", the conscious experience of the body as one's own.

    I investigate how humans recognize their own bodies by causing illusion as if virtual bodies with different characteristics from their own physical bodies are as their own bodies.

     

    From an artistic point of view, I made this work with the aim of creating new types of human-tool interaction.
    In our long history, humans have invented tools that are fit for our constrained bodies and evolved ourselves by tool-use.

    Now that we can invent our bodies that are fit for the existing tools by using VR technologies, resulting in a novel human-tool coevolution.

    Swinging 3D Lamps

    "Swinging 3D lamps (youtube) " is a novel naked-eye 3D spatial augmented reality technology that makes a static 2D image look like 3D by adding only motion signals on it.

    It creates optical 3D illusions of motion parallax by superimposing luminance motion signals on a common picture in a real environment by using a projector.

    Our basic idea is to combine ”wiggle stereoscopy”, which is a phenomenon involving 3D perception by exploiting motion parallax with ”deformation lamps”, which is a projection technique to make static pictures dynamic.

    Embodied Spatial Perception in VEs

    In virtual environments (VEs), we handle virtual bodies with different sizes and characteristics from our actual body.

    I am considering how this affects the way we perceive the external world.

    Especially, I am focusing on the phenomenon that the scale of the self-body influences the scale of the world (body-based scaling).

    I am also examining the difference in the scale perception between the real and virtual environments.
