Search Results for "target"

Traditional URLs are simple and easy to use, but they’re also quite limited. For one thing, a URL only points at a single, complete document. More granularity than that, such as linking to the third sentence of the seventeenth paragraph in a document, requires the author of the targeted document to manually insert named anchors at the targeted location. The author of the document doing the linking can’t do this unless he or she also has write access to the document being linked to. Even if the author doing the linking can insert named anchors into

This project focuses on exploring multimodal interaction in immersive environments, particularly on the problem of target disambiguation while selecting an object in 3D. We have created an interactive 3D environment as our test bed and have used it in a variety of augmented reality (AR) and virtual reality (VR) scenarios.Often in 3D immersive environments the user is faced with many selection problems, such as imprecise pointing at a distance, selection of occluded/hidden objects, and recognition errors (e.g., speech recognition errors). Our goal is to

The research on Virtual Reality being carried out at VRLAB is around the topic of multimodal human-computer interaction in virtual environments. We focus mainly on developing new interaction metaphors integrating 3D sound, stereo visualization, and force feedback, towards more intuitive and immersive systems for several applications. Multimodal Interactive VR Systems One of the investigated topics concerns the use of intelligent avatars (or autonomous virtual assistants) to efficiently perform tasks in cooperation with the user. In this context,

Outside of custom editors and viewers, reading XML data is comparatively difficult. A lightweight approach for viewing XML is to attach a cascading style sheet (CSS2) to XML documents and then use a recent Web browser to view them (Mozilla is excellent, IE often adequate). developerWorks columnist David Mertz takes a look at this alternative approach in this tip. Reading XML documents is not easy -- for a human. XML documents are all text, but the visual arrangement of parts does not necessarily correspond well to the conceptual connections between
