Search results

Keywords search is intuitive, simple to use and convenient. It is also the de facto input interface for textual and multimedia retrieval. However, individuals often perform poorly when faced with exploratory search tasks that are common during learning, resulting in poor quality searches. The purpose of this paper is to examine how adolescent learners search and select videos to support self-learning. The findings allow for the identification of design concepts of video retrieval interface and features that can facilitate better exploratory searches.

Participants were assigned two customized video search tasks. The think-aloud protocol is used to allow participants to verbalize their actions, thoughts and feeling. This approach offered rich insights to the participants’ cognitive processes and considerations when performing the search tasks.

This study identified five themes for exploratory video search behavior: selection of internet resources, query formulation/reformulation, selection of the video(s) for preview, getting acquainted with the video content, and making a decision for the search task. The analysis of these themes led to a number of design concepts, ranging from supporting exploration of topics to better interaction with metadata.

The findings can inform future development of dedicated video retrieval systems interfaces that seeks to facilitate effective exploratory searches by learners.

This study contributes by suggesting design concepts for video retrieval system developers to support exploratory video searches.

The New Macintoshes as Library Appliances. Can an information appliance be a library workstation? Can a computer that is low‐cost, easy‐to‐use, and relatively fast for its price also crunch data, manipulate text, invent graphics, and respond to sound? If a CPU is designed for consumers can it also work in libraries? Or should librarians resign themselves to the hands of specialists, those who argue that the best machine to handle bibliographic files is large, complex, and expensive?

HAS BRITAIN really lost its sense of purpose? Has it no noticeable industrial policy?

THAT THE NEWSPAPER industry has gone through a tremendous change has been obvious to all by the horrific scenes of violence shown on television over the past several months.

The purpose of this paper is to present a framework applicable to interactive video retrieval. The objective of the framework is so that it can be applied conceptually for understanding users and use of video digital libraries, and also practically for designing retrieval components like user interfaces.

The framework was developed through a user-centered and analytical approach, and serves as an initial attempt at generalizing how users interact when searching and browsing digital video, throughout different situations, along with the general designs that can be supportive.

The framework is two-fold, yet, together, comprises one set of conceptual findings. The first component of the framework depicts generalized user interactions throughout varying contexts of an interactive video retrieval process, followed by a second component, an illustration of the resulting supportive interface designs or sets of features. Cautions from previous studies not to over generalize the interactive process were heeded.

The implications for such research are based on the understanding that video retrieval will benefit from the advancement of user-centered foundations, which can guide and support design decisions for resources like digital libraries.

The need for this study is rather straightforward: there is currently not enough conceptual research of interactive video retrieval from a user-centered perspective, which contrasts with other areas of information retrieval research where the interaction process has been thoroughly examined for a variety of domains and contexts with implications for different retrieval tools like OPACs, search engines, and article databases.

The purpose of this study is to develop an environment where participants share a virtual workspace, which allows the participants to collaborate on a physical model as well as a digital model in a natural manner as if they were in a face‐to‐face meeting.

The idea of this study was designed and implemented as BOCOLLA system based on CELAVIS system. BOCOLLA system enables users to manipulate computer software on a conventional whiteboard using a marker pen during video conference with CELAVIS system.

BOCOLLA system shows the feasibility of the non‐IT interface with a conventional whiteboard as an IT‐based interface which enables telematic operation for video conferences.

Digital models plays a critical role in e‐manufacturing, but their physical models would enhance the collaboration in e‐manufacturing if it could be shared among the collaboration members over the network.

The study identifies the potential of conventional tools as an interface to the innovative technologies.

Using a physical model sharing example, this paper shows the feasibility of BOCOLLA to the application of e‐manufacturing.

In the context of information storage and sharing new electronic technology has much to offer conventional library systems. A video disc can be a valuable storage component. However, its full potential is unlikely to be realised if it is used in isolation from other equipment. Computers, communication networks and video discs can together provide many novel information storage and dissemination systems for use in libraries. This paper describes some of these and also gives a brief outline of some approaches to providing the all important user interface to such systems.

The purpose of this paper is to report on a user-centred analysis of video digital libraries and to present users’ criteria based on concepts emerging directly from the responses of study participants. As a time-based and multi-channeled format, video warrants considerations for information delivery through interactive tools such as digital libraries.

A survey method was used to collect open-ended responses from participants. Content analysis was performed on the responses, and categories then emerged to form the coding scheme where simple and weighted frequencies were calculated to obtain a ranked set of users’ criteria. Cohen’s κ was 0.87, indicative of high-level of inter-coder reliability. In the end, 81 participants contributed a total of 385 open-ended responses, which were all then analysed and coded.

The emergent coding method and continuous refinements to the coding scheme ultimately produced 28 criteria (subcategories) under four primary categories. Criteria corresponding to “retrieval functionality” of video digital libraries emerged as the highest, or most frequently referenced, primary category, while the “user interface”, “collection qualities”, and “user support” followed, respectively.

The primary research contribution is a baseline for video digital libraries that can be applicable throughout design and evaluation. Future studies can utilise findings presented here as guidance for the initial design stages and/or for assessing systems via targeted evaluations.

While users’ criteria of digital libraries have been analysed from non-visual contexts, they have not been directly assessed as they pertain to users’ experiences and perceptions with video, which is needed as the nature and structure of video can influence users and use.

The purpose of this paper is to examine perceived self-efficacy of users within an interactive video retrieval context. The motivation for this research includes that understanding self-efficacy will provide insight on how potential users target resources and in turn promote and sustain use of retrieval tools and systems.

A survey method was employed. In total, 270 participants rated levels of perceived self-efficacy for successfully fulfilling different video needs if using a particular system. Perceived self-efficacy was explored quantitatively, both overall and across different potentially influential factors, such as topic type, topic familiarity, system experience, and system context. In addition, open-ended responses on the survey were categorized through content-analysis and subsequently analyzed using weighted frequencies.

Findings demonstrated significant associations between participants’ perceived self-efficacy and different topical factors, including familiarity and topic type, and also system factors, such as exposure (or experience) and system context.

User confidence is one belief or attitude about technology acceptance, with self-efficacy intersecting multiple factors related to initial and sustained use of technologies. Findings give researchers a look at users’ preconceptions of interactive video retrieval situations, which, in turn, suggest positive implications for future research and design.

Video retrieval comprises considerations that are unique from other contexts due to the structure and physical makeup of video. However, until now, self-efficacy has not been directly examined in relation to video or according to several of the specific retrieval factors as explored in the current study, which is thus warranted.

The use of the Internet for Web‐based teaching and learning is fast becoming a reality. However, since it is difficult to verify the identity of the student through a simple user ID and password system on the client side, performance evaluation through test and examination through the Internet is still in its infancy. To overcome this main hurdle, a system has been designed and developed where a camera at the client computer is used to capture the student’s face and posture at random intervals during the test. The captured images are stored at the server and can be used to verify the identity of the person taking the test if the need arises. The system developed has been successfully used in a randomized multiple choice test in a course on analog and digital signals involving 450 students.
