Multimedia Authoring Tool

Abstract. This paper consists of an in-depth summary and analysis of the research and development state of the art for intelligent tutoring system (ITS) authoring systems. A seven-part categorization of two dozen authoring systems is given, followed by a characterization of the authoring ...

Digital video is becoming increasingly ubiquitous. However, editing video remains difficult for several reasons. It is a time-based medium, it has dual tracks of audio and video, and current tools force users to work at the smallest level of detail. In this paper, we describe several visualization and interaction techniques that use video metadata, including a transcript, to mitigate the problems of editing in this domain. We implemented these techniques in Silver, an authoring tool designed to make it easier for novice users to edit video. To help users visualize video, Silver provides multiple views with different semantic content and at different levels of abstraction, including storyboard, editable transcript and timeline views. Silver offers intelligent editing operations that help users resolve the inconsistencies that arise because of the different boundaries in audio and video. We conducted a preliminary user study to investigate the effectiveness of the system. Participants...

The need for e-learning systems that support a diverse set of pedagogical requirements has been identified as an important issue in web-based education. Until now, significant R&D effort has been devoted aiming towards web-based educational systems tailored to ...

The World Wide Web (WWW) is now accepted as a de facto standard for human–computer interaction and human–human communication, so it is desirable to develop net-centric, multimedia and collaborative applications. In this paper, we present a new scripting language, JACIE, designed to support rapid prototyping and implementation of such applications. The support for the management of multimedia interaction and communication in collaborative applications is highlighted. JACIE facilitates such support through the concepts of channels and a collection of interaction protocols. A template-based programming style is adopted by JACIE, using a single program for both client and server, and platform-independence achieved by employing Java as the target language. All these features characterise a desirable multimedia software engineering tool.

Authoring tools are a crucial component in the practice and research of interactive digital narrative design, yet no recent meta-analysis or mapping of such tools exists that would make it possible to comparatively study their defining qualities and characteristics and their effects on the artefacts produced with them. As a first step towards this goal, we created an online resource [1] in which we surveyed and classified over 300 tools. This paper lays out our proposed categorisation and description framework for IDN authoring tools. After exploring our definition of authoring tools and research methodology, we describe 9 categories and 38 descriptors for tool analysis and comparison. We conclude with a sample analysis of Twine [2].

In this work we describe a 3D authoring tool which takes advantage of multimodal interfaces such as gestures and speech. This tool allows real-time Augmented Reality aimed to aid the tasks of interior architects and designers. This approach intends to be an alternative to traditional techniques. The main benefit of using a multimodal based augmented reality system is the provision of a more transparent, flexible, efficient and expressive means of human-computer interaction.

The DARWARS Tactical Language Training System (TLTS) helps learners acquire basic communicative skills in foreign languages and cultures. Learners practice their communication skills in a simulated village, where they must develop rapport with the local people, who in term will help them accomplish missions such as post-war reconstruction. Each learner is accompanied by a virtual aide who can provide assistance

In the last years, authoring based on e-learning standards has been consolidated as a core factor of industry and development of interoperable and effective virtual learning environments. However, there is a need for further research on abstraction to provide a more instructional view in the context of authoring tools in a variety of ways, in order to avoid being driven by Learning Technology (LT) specifications, facilitate instructional knowledge aggregation, and to provide an appropriate level of clarity and semantics in the design of collaborative activities. We propose a combination of techniques to provide this instructional abstraction in the context of the new European educational model, combining instructional layers and collaborative scripts in authoring tools, and semantic web techniques for extending e-learning material in order to harness the wealth of existing web content and semantically labeled repositories.
