    Request Permissions | Click to expandAbstract | PDF file iconPDF (3315 KB) |  | HTML iconHTML  

    Simulating complex events is a challenge and often requires carefully selecting simulation parameters. As vast computation resources become available, researchers can run alternative parameter settings or simulation models in parallel, creating an ensemble of possible outcomes for a given event of interest. The visual analysis of ensembles is one of visualization's most important new areas and sho... View full abstract»

    A proposed real-time neurosurgery simulator handles skull drilling and surgical interaction with the brain. This involves the development and combination of areas such as collision handling, haptic rendering, physical simulation, and volumetric visualization. The simulator's input data comes from computed-tomography and magnetic-resonance-imaging images of the patients. Collision detection for dri... View full abstract»

  • The IrPen: A 6-DOF Pen for Interaction with Tablet Computers

    Publication Year: 2014 , Page(s): 22 - 29
    Request Permissions | Click to expandAbstract | PDF file iconPDF (4584 KB) |  | HTML iconHTML  

    Researchers have proposed various techniques for over-the-surface interaction using pens. However, current pen systems can't properly support these techniques because of their limited tracking abilities. The IrPen, an extension of the IrCube tracker, is a six-degree-of-freedom pen system that properly supports over-the-surface interaction on tablet computers. Besides incorporating the tracker's ba...

  • 3D Object Manipulation Using Virtual Handles with a Grabbing Metaphor

    Publication Year: 2014 , Page(s): 30 - 38
    Request Permissions | Click to expandAbstract | PDF file iconPDF (3964 KB) |  | HTML iconHTML  

    This technique lets users manipulate 3D objects as if they had actually grabbed them. It employs a grabbing metaphor to provide the mapping protocol for finding the desired reference frame for the object. The technique projects the user's hand into the virtual environment; a virtual-handle avatar provides feedback. View full abstract»

    A proposed multitouchless interface accurately tracks users' hands and fingers in 3D, using a Microsoft Kinect sensor. The system tracks up to four hands simultaneously on a standard desktop computer at 30 fps, with approximately 5-mm accuracy. From this basic tracking, the system identifies gestures and uses them for interaction. The Making Sense demonstrator applied this technology to let users ... View full abstract»

  • 3D Volume Drawing on a Potter's Wheel

    Publication Year: 2014 , Page(s): 50 - 58
    Request Permissions | Click to expandAbstract | PDF file iconPDF (5646 KB) |  | HTML iconHTML  

    The proposed 3D-volume-drawing interface can easily create various organic, artistic models. To provide intuitiveness, it adopts the metaphor of the potter's wheel. With one hand, users control a wooden wheel whose rotation is synchronized with that of the virtual space. A 3D depth camera captures the mid-air poses of the users' other hand, which the system translates into a virtual brush for inte... View full abstract»

    Request Permissions | Click to expandAbstract | PDF file iconPDF (4908 KB) |  | HTML iconHTML  

    ClaytricSurface is a shape-changeable display with dynamic stiffness control. The prototype uses vacuum pressure control on an enclosed volume of particles. Users can mold 3D shapes and apply textures to them while experiencing tactile feedback through dynamically changing stiffness. The system's developers have added both touch input using a depth camera and peripheral devices to expand the syste... View full abstract»

    Visual programming in 3D sounds much more appealing than programming in 2D, but what are its benefits? Here, University of Colorado Boulder educators discuss the differences between 2D and 3D regarding three concepts connecting computer graphics to computer science education: ownership, spatial thinking, and syntonicity.

  • Mixed-Reality Humans for Team Training

    Publication Year: 2014 , Page(s): 72 - 75

    Researchers have created mixed-reality humans (MRHs) and applied them to critical team training. MRHs are embodied conversational agents with virtual and physical components that inhabit the user's space. In this research, MRHs role-played members of an operating-room team. Studies examined how MRH components affected social presence (the user's sense of "being there" with an embodied conversation... View full abstract»

    Tangible cultural heritage has provided visually appealing material for those researching in computer graphics, computational geometry, and interactive techniques. However, experiments were initially of more benefit to computer scientists as tests for their novel techniques than of any practical benefit to cultural-heritage professionals. Recently, however, tools have matured considerably, and tec... View full abstract»
