Device-Independent Navigation and Interaction in Virtual Environments
We present a new approach to the integration of input devices into virtual environment software systems. Our approach employs a so-called Mapper module as an intermediate between input device drivers and virtual environment application. Major advantages of our approach are full device-independence, including the easy integration of new input devices and emulation of missing device capabilities,...
متن کامل(CTA)3[SiW12]-Li+-MMT: Efficient nanocatalyst for the synthesis of 3,4-dihydropyrimidin-2(1H)-ones under solvent-free conditions
A highly practical and efficient preparation of 3,4-Dihydropyrimidin-2(1H)-one derivatives was developed via an efficient and simple nanocatalyst and promoted multi-component reaction of ethyl acetoacetate, aromatic aldehyde, and urea in the presence of a catalytic amount of (CTA)3[SiW12]-Li+-MMT under solvent-free conditions. In comparison to the conve...

متن کاملStrolling Through Cyberspace With Your Hands In Your Pockets: Head Directed Navigation In Virtual Environments
Head-Directed Navigation is a new and simple, yet efficient paradigm for navigating large virtual spaces. For walkthrough applications such as architectural visualization or games, the user is often required to cover simulated distances. In doing so, unexperienced users often have a hard time learning complicated navigation patters with 3-D mice or similar input devices. In large virtual worlds...
متن کاملAlternative input devices for efficient navigation of large CT angiography data sets.
PURPOSE To compare devices for the task of navigating through large computed tomographic (CT) data sets at a picture archiving and communication system workstation. MATERIALS AND METHODS The institutional review board approved this study, and all subjects provided informed consent. Five radiologists were asked to find 25 different vascular targets in three CT angiography data sets (average nu...
