Introduction: As the number of people with visual impairments (that is, those who are blind or have low vision) is continuously increasing, rehabilitation and engineering researchers have identified the need to design sensory-substitution devices that would offer assistance and guidance to these people for performing navigational tasks. Auditory…

Purpose: The purpose of this paper is to propose an indexing and teaching focus mining system for lecture videos recorded in an unconstrained environment. Design/methodology/approach: By applying the proposed algorithms in this paper, the slide structure can be reconstructed by extracting slide images from the video. Instead of applying…

Purpose: Social navigation is an emerging trend for navigation in hypermedia. With social navigation, users can be guided through large volumes of learning content by cues which integrate the browsing history of past users. Earlier papers have shown that social navigation is suitable for navigation not only in classic hypermedia but also in…

Instructional elements remain the foundation of current instructional design practice. Practice is the instructional element provided after learners have been given information required to master an objective and Navigation is the non-instructional element guides the learner on the sequence of instruction. Linear Navigation can be referred to as…

The Virtual Grand Tour (VGT) is a paradigm for integrating a presentation of an overview of a larger subject with the possibility of launching at any time an exploratory study of a given sub-topic. The name derives from the paradigm's emulation of those 18th-century travels intended to educate (especially) young, affluent British men; today, with…

This paper presents a high-level course in computing for non-majors offered at Queens College (New York). The course focuses on the acquisition and presentation of data and information. For data acquisition, the course will give the students high-level mastery of the Internet. For the presentation of information, the students will learn multimedia…

Computer applications that facilitate the use of the World Wide Web (WWW) within elementary and secondary education must provide support for educators to locate materials quickly and easily; they must minimize the amount of time spent waiting for files to traverse the network; and they must deal sensitively with censorship. The MicroWeb Toolkit is…
