    Developing realistic tactile displays for virtual reality has been challenging. Tangible displays are increasingly important interfaces not only for augmenting the reality of computer graphics but also for conveying graphical information to persons with visual impairments. We propose a tactile display using surface a acoustic waves. We can continuously change the fineness of the surface's grain by... View full abstract»

    For part 2, see ibid., September/October (2001). Every now and then surprising new theories appear on the scientific stage that hold the promise of dramatic new technologies. Quantum computing is one of these. The ideas in this field radically change the way we think about computers and computing. in my last two columns, I introduced the theory of quantum computing and presented its basic terminol...

    We introduce a new projection-based AR display system-the Virtual Showcase. The Virtual Showcase has the same form factor as a real showcase, making it compatible with traditional museum displays. Real scientific and cultural artifacts are placed inside the Virtual Showcase allowing their 3D graphical augmentation. Inside the Virtual Showcase, virtual representations and real artifacts share the s... View full abstract»

    In 1997, Azuma published a survey on augmented reality (AR). Our goal is to complement, rather than replace, the original survey by presenting representative examples of the new advances. We refer one to the original survey for descriptions of potential applications (such as medical visualization, maintenance and repair of complex equipment, annotation, and path planning); summaries of AR system c...

    We present some applications that therapists have used with patients. Treating psychological disorders is one aspect of a larger application area of VR that we refer to as clinical virtual reality-the direct use of VR as a tool in treating or assessing psychological and physical disorders. Examples of clinical applications that use VR include treatment of phobias, post-traumatic stress disorder in... View full abstract»

  • Mixed reality: future dreams seen at the border between real and virtual worlds

    Mixed reality (MR) is a kind of virtual reality (VR) but a broader concept than augmented reality (AR), which augments the real world with synthetic electronic data. On the opposite side, there is a term, augmented virtuality (AV), which enhances or augments the virtual environment (VE) with data from the real world. Mixed reality covers a continuum from AR to AV. This concept embraces the definit... View full abstract»

    It makes sense that humans-with their forward-facing eyes-would understand the patterns of the world through sight rather than sound. The form of creatures long past, their evolution and growth, even the development of our own form as we grow in life are mysteries to us today. But, buried in the past are keys to unlocking our understanding of form. We may still use tools such as picks and shovels ... View full abstract»

  • Interface with angels: the future of VIR and AR interfaces

    Although real guardian angels aren't easy to get hold of, some of the computer technology needed for such a personal assistant is already available. Other parts exist in the form of research prototypes, but some technological breakthroughs are necessary before we can realize their potential, let alone integrate into our daily routines. Future VR and AR interfaces won't necessarily try to provide a... View full abstract»

    Photorealistic rendering of graphical models continues to be a topic of considerable research effort in the computer graphics community. However, photorealism isn't the only criterion for judging an image's value. In visualization, where rendering is the conduit through which abstract, nonrealistic forms (such as isosurfaces or streamtubes) become perceivable to users, photorealism may neither be ...
