Multimedia hypertext has grown from the basic addition of dynamic media only at "leaf" nodes of the hypertext, to higher structured attempts to compose and integrate the different media. One of the core problems in this evolution has been, and still is, the construction and perception of context, making explicit which part of a presentation is relevant when media elements are integrated. The search for contextualized integration of video material with other sources of information has emerged from the work in several domains and from mutually reinforcing needs. The work presented here is centered on this problem: how to provide the perception of context to users or readers, when navigating through a space of heterogeneous media elements, where video plays an important role.
In the search of alternative ways to learning veterinary surgery with live animals, hypervideo was considered a promising candidate as a learning tool. Video can enhance the realism and authenticity of a learning environment. By adding structure and interactivity to video, hypervideo allows to navigate video and to explore other related media to complement it. Hypervideo might then support the creation of a rich and realistic learning environment, through the interactive access, construction and communication of knowledge on veterinary surgery. In this paper, we present the design and evaluation of Hvet, a hypervideo environment to support learning of veterinary surgery. Design was based on cognitive and media theories, and evaluation was based on the use of Hvet by veterinary students, in order to test its efficacy in substitution of learning and training with live animals. Results support the hypothesis, showing the potential of hypervideo as a valuable and effective tool to support learning of surgery techniques and revealing the most appreciated design options.
In traditional video, the user is locked to the angle where the camera was pointing to during the capture of the video. With 360º video recording, there are no longer these boundaries, and 360º video capturing devices are becoming more common and affordable to the general public. Hypervideo stretches boundaries even further, allowing to explore the video and to navigate to related information. In this paper, we describe an approach to the design and development of an immersive and interactive interface for the visualization and navigation of 360º hypervideos over the internet. Such videos allow users to pan around to view the contents in different angles and effectively access related information through the hyperlinks. Challenges for presenting this type of hypervideo include: providing users with an appropriate interface capable to explore 360º contents, where the video should change perspective so that the users actually get the feeling of looking around; and providing the appropriate affordances to understand the hypervideo structure and to navigate it effectively in a 360º hypervideo space, even when link opportunities arise in places outside the current viewport.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
