    Millions of children worldwide are born with defects known as cleft lips and palates. These defects cause major deformities to a person's face, and can lead to other health problems. Unfortunately, many children with such defects cannot afford the surgery required to correct the problem. The Smile Train is a charity which provides free training, education and equipment to help local doctors perfor... View full abstract»

    Diverse museum artifacts, such as ceramics, porcelain, and ritual bronzes, can convey a sense of a people's history and culture, time, or place. Following specific criteria about the protection, maintenance, and preservation of these artifacts ensures their proper care and restoration. Often, this means visitors must view the artifacts statically in a glass showcase, precluding any kind of physica... View full abstract»

    The Last clock displays a space's history and rhythm. Trails behind its hands paint the clock face with a video feed, creating a mandala of archived time. The Last clock began as an investigation into representations of time. The goal was to use the mutable properties of digital technology, hoping to create something aesthetically pleasing, interesting, and ever changing without having to succumb ... View full abstract»

    A locomotion interface for swimming and floating in a virtual ocean is part of the interactive installation of the Swimming Across the Pacific artwork. In the 'Swimming Across the Pacific' artwork, the authors create a space for collaborative artwork in an airplane by having a swimmer swim while flying across the Pacific Ocean. The swimmer's swimming represents a transformation of the airplane int... View full abstract»

  • Harnessing real-world depth edges with multiflash imaging

    Publication Year: 2005, Page(s):32 - 38
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1376 KB) | HTML iconHTML

    A method for capturing geometric features of real-world scenes relies on a simple capture setup modification. The system might conceivably be packaged into a portable self-contained device. The multiflash imaging method bypasses 3D geometry acquisition and directly acquires depth edges from images. In the place of expensive, elaborate equipment for geometry acquisition, we use a camera with multip... View full abstract»

    Handheld projection lets users create opportunistic displays on any suitable nearby surface. This projection method is a practical and useful addition to mobile computing. Incorporating a projector into a handheld device raises the issue of how to interact with a projection. The focus of the article is interactive projection: a technique for moving a cursor across a projection, allowing all the fa... View full abstract»

    An untethered VR system with force feedback based on the use of air pressure gives the user the feeling of touching an object. The result is an untethered human interface that's easy to use in everyday life. The system uses a projection-based stereo display and optical position tracking. The user employs red and blue 3D glasses and a lightweight paddle. This article is available with a short video... View full abstract»

    A novel tabletop display provides different images to different users surrounding the system. It can also capture users' gestures and physical objects on the tabletop. The Lumisight Table approach is based on the optical design of a special screen system composed of a building material called Lumisty and a Fresnel lens. The system combines these films and a lens with four projectors to display fou... View full abstract»

    Time-Followers's Vision is a mixed-reality-based visual presentation system that captures a robotic vehicle's size, position, and environment, allowing even inexperienced operators to easily control it. The technique produces a virtual image using mixed reality technology and presents the vehicle's surrounding environment and status to the operator. Therefore, even for inexperienced operators, the... View full abstract»

    The CirculaFloor locomotion interface's movable tiles employ a holonomic mechanism to achieve omnidirectional motion. Users can thus maintain their position while walking in a virtual environment. The CirculaFloor method exploits both the treadmill and footpad, creating an infinite omnidirectional surface using a set of movable tiles. The tiles provide a sufficient area for walking, and thus preci... View full abstract»

    The desire to reproduce and expand the human senses drives innovations in sensor technology. Conversely, human-interface research aims to allow people to interact with machines as if they were natural objects in a cybernetic, human-oriented way. We wish to unite the two paradigms with a haptic sensor as versatile as the sense of touch and developed for a dual purpose: to improve the robotic capabi... View full abstract»

    Nonlinear projections and implementations are largely unexplored in 3D environments. A technique for generating deformed 3D visual effects using nonlinear perspective projections allows real-time navigation of 3D environments. The authors derive their deformation algorithms from 3D nonlinear perspective projections, which consider factors such as depth, view angle, and camera position-parameters 2... View full abstract»

    For Part 2 see ibid., vol.24, no.6 (2004). The article finishes a three-part series on crop circles and crop formations. Part 1 (see ibid., vol.24, no.5, 2004) talked about the history of crop circles, and the people who make and study them. The author also presented the strange story of the five Hawkins Theorems, and showed how to construct the basic geometrical skeleton for a crop design. In Par... View full abstract»
