Streszczenie:

The area of multimedia information retrieval (MMIR) faces two major challenges: the enormously growing number of multimedia objects (i.e., images, videos, audio, and text files), and the fast increasing level of detail of these objects (e.g., the number of pixels in images). Both challenges lead to a high demand of scalability, semantic representations, and explainability of MMIR processes. Smart MMIR solves these challenges by employing graph codes as an indexing structure, attaching semantic annotations for explainability, and employing application profiling for scaling, which results in human-understandable, expressive, and interoperable MMIR. The mathematical foundation, the modeling, implementation detail, and experimental results are shown in this paper, which confirm that Smart MMIR improves MMIR in the area of efficiency, effectiveness, and human understandability.

Streszczenie:

Multimedia information is now routinely available in the forms of text, pictures, animation and sound. Although text objects are relatively easy to deal with (in terms of information search and retrieval), other information bearing objects (such as sound, images, animation) are more difficult to index. Our research is aimed at developing better ways of representing multimedia objects by using a conceptual representation based on Schank's conceptual dependencies. Moreover, the representation allows for users' individual interpretations to be embedded in the system. This will alleviate the problems associated with traditional semantic networks by allowing for coexistence of multiple views of the same information. The viability of the approach is tested, and the preliminary results reported.

Streszczenie:

The identification of the overlapped objects is a great challenge in object tracking and video data indexing. For this purpose, a backtrack-chain-updation split algorithm is proposed to assist an unsupervised video segmentation method called the "simultaneous partition and class parameter estimation" (SPCPE) algorithm to identify the overlapped objects in the video sequence. The backtrack-chain-updation split algorithm can identify the split segment (object) and use the information in the current frame to update the previous frames in a backtrack-chain manner. The split algorithm provides more accurate temporal and spatial information of the semantic objects so that the semantic objects can be indexed and modeled by multimedia input strings and the multimedia augmented transition network (MATN) model. The MATN model is based on the ATN model that has been used in artificial intelligence (AI) areas for natural language understanding systems, and its inputs are modeled by the multimedia input strings. In this paper, we will show that the SPCPE algorithm together with the backtrack-chain-updation split algorithm can significantly enhance the efficiency of spatio-temporal video indexing by improving the accuracy of multimedia database queries related to semantic objects.

Streszczenie:

Recent technological developments have increased the use of machine learning to solve many problems, including many in information retrieval. Multimedia information retrieval as a problem represents a significant challenge to machine learning as a technological solution, but some problems can still be addressed by using appropriate AI techniques. We review the technological developments and provide a perspective on the use of machine learning in conjunction with knowledge organization to address multimedia IR needs. The semantic gap in multimedia IR remains a significant problem in the field, and solutions to them are many years off. However, new technological developments allow the use of knowledge organization and machine learning in multimedia search systems and services. Specifically, we argue that, the improvement of detection of some classes of low-level features in images music and video can be used in conjunction with knowledge organization to tag or label multimedia content for better retrieval performance. We provide an overview of the use of knowledge organization schemes in machine learning and make recommendations to information professionals on the use of this technology with knowledge organization techniques to solve multimedia IR problems. We introduce a five-step process model that extracts features from multimedia objects (Step 1) from both knowledge organization (Step 1a) and machine learning (Step 1b), merging them together (Step 2) to create an index of those multimedia objects (Step 3). We also overview further steps in creating an application to utilize the multimedia objects (Step 4) and maintaining and updating the database of features on those objects (Step 5).

Streszczenie:

This paper illustrates an object-oriented programming environment, called Application Conference Interface (ACI), which has been designed in order to facilitate the implementation of cooperative information systems. It interfaces developers of cooperative applications with services provided by a software platform, called ImagineDesk. The platform offers a rich set of services which can be exploited by developers of cooperative applications in order to manage them, to exchange multimedia data and to control users' interactions according to their roles. Basically, the ACI provides a set of local abstractions of remote services. These abstractions take the form of local objects, hiding the details of the underlying physical network from the application developer. By exploiting the object-oriented paradigm, the ACI clearly confines the host environment and network constraints in few easily upgradable objects, thus resulting in a highly system-independent architecture.

Multimedia information has been extensively growing from a variety of sources such as cameras or video recorders. In order to select the useful multimedia objects, multimedia recommender system has been emerging as a tool to help users choose which multimedia objects might be interesting for them. However, given the complexity of multimedia objects, it is challenging to provide effective multimedia recommendations. In this paper, we therefore conduct a survey in both the multimedia information system and recommender system communities. We further focus on the works that span the two communities, especially the research on multimedia recommender systems. Based on our review, we propose a set of research challenges, which can be used to implicate the future research directions for multimedia recommender systems. For each research challenge, we have also provided the insights of how to perform the follow-up research.

Information is being presented these days in terms of text, data, images, video, and audio. Graphics and animations. Information is being disseminated through web sites which are either dynamic or static. Quality of the WEB site is however a big question. Users are quite concerned about quality of the WEB site. Too many operations if need to be undertaken for want of quality visualisation of the content such as Images, then the users loose interest in looking at that kind of content. WEB sites are presenting the content by integrating text and data with multimedia objects. Quality visualisation of the multimedia content would be the real issue as presenting these elements. The number of operations that the user is expected to carry must be minimised as much as possible.Quality presentation of the multimedia objects is most important for making available web sites to the customer satis-faction. Assessment of quality of the multimedia objects is needed to project the extent to which the users will be satis-fied with a web site that hosts different types of multimedia objects. In this paper the methods that computes quality of multimedia objects individually and also considering all types of multi-media objects as a whole are presented.

Streszczenie:

With the widespread availability of media technologies, such as real-time streaming, new Internet-of-Thing devices and smart phones, multimedia data are extensively increased and the big multimedia data rapidly spread over various social networks. This has created complexity and information overload for users to choose the suitable multimedia objects. Thus, different multimedia recommender systems have been emerging to help users find the useful multimedia objects that are possibly preferred by the user. However, the evaluation of these multimedia recommender systems is still in an ad-hoc stage. Given the distinct features of multimedia objects, the evaluation criteria adopted from the general recommender systems might not be effectively used to evaluate multimedia recommendations. In this paper, we therefore review and analyze the evaluation criteria that have been used in the previous multimedia recommender system papers. Based on the review, we propose a generalized evaluation framework to guide the researchers and practitioners to perform evaluations, especially user-centric evaluations, for multimedia recommender systems.

One of the most important challenges in the information access field, especially for multimedia repositories, is information overload. To cope with this problem, in this paper, the authors present a strategy for a recommender system that computes customized recommendations for users’ accessing multimedia collections, using semantic contents and low-level features of multimedia objects, past behaviour of individual users, and social behaviour of the users’ community as a whole. The authors implement their strategy in a recommender prototype for browsing image digital libraries in the Cultural Heritage domain. They then investigate the effectiveness of the proposed approach, based on the users’ satisfaction. The preliminary experimental results show that the approach is promising and encourages further research in this direction.

Streszczenie:

The modeling of multimedia databases in the context of multimedia information systems is a complex task. The designer has to model the structure and the dynamic behavior of multimedia objects, together with possible user interactions with them. These can include content-based queries, and dynamic presentations, which might both require the construction of special index structures on the stored data. In this paper we present a methodology for the design of multimedia databases. The methodology extends some of the Unified Modeling Language (UML) diagrams with constructs to model the structure of multimedia objects, their dynamic behavior, presentation layout, and user interactions. These constructs allow a designer to model important aspects of database oriented multimedia applications. As a consequence, it is possible to construct refinement techniques to map our high level models onto logical data models of several target multimedia DBMSs. In particular, we describe how to map our conceptual models onto extended relational data models.

In this paper, we are interested in XML multimedia retrieval, the aim of which is to find relevant multimedia objects such as images, audio and video through their context as document structure. In context-based multimedia retrieval, the most common technique is based on the text surrounding the image. However, such textual information can be irrelevant to the image content. Therefore many works are oriented to the use of alternative techniques to extend the image description, such as the use of ontologies, relevance feedback, and user profiles. We studied in our work the use of links between XML elements to improve image retrieval. More precisely, we propose dividing the document into regions through the document structure and image position. Then we weight links between these regions according to their hierarchical positions, in order to distinguish between links that are useful and those that are not useful. We then apply an updated version of the HITS algorithm at the region level, and compute a final image score by combining link scores with initial image scores. Experiments were done on the INEX 2006 and 2007 multimedia tracks, and showed the potential of our method.

Streszczenie:

Multimedia feature graphs are employed to represent features of images, video, audio, or text. Various techniques exist to extract such features from multimedia objects. In this paper, we describe the extension of such a feature graph to represent the meaning of such multimedia features and introduce a formal context-free PS-grammar (Phrase Structure grammar) to automatically generate human-understandable natural language expressions based on such features. To achieve this, we define a semantic extension to syntactic multimedia feature graphs and introduce a set of production rules for phrases of natural language English expressions. This explainability, which is founded on a semantic model provides the opportunity to represent any multimedia feature in a human-readable and human-understandable form, which largely closes the gap between the technical representation of such features and their semantics. We show how this explainability can be formally defined and demonstrate the corresponding implementation based on our generic multimedia analysis framework. Furthermore, we show how this semantic extension can be employed to increase the effectiveness in precision and recall experiments.

Multimedia authoring tool serves to facilitate an author to create multimedia presentations. Multimedia authoring tool will convert the multimedia presentation into a document. Mobile devices with different screen sizes that can cause visual media to overlap are called Spatio-temporal conflict. The process in the multimedia authoring tool involves a Spatio-temporal verification process to detect Spatio-temporal conflicts. This study proposes a method for correcting the conflict using a conflict region detection process, Spatio-temporal verification, and auto-correction. The auto-correction method uses two stages of area relocation for vertical conflict and horizontal conflict. The two stages are repeated for the ability to correct up to four conflicting regions. Visual media objects such as overlapping images and videos were successfully separated into non-overlapping media objects. The proposed method succeeded in separating the four media objects that were previously overlapping.

On the grounds, ontologies have been shown to be a powerful resource for the interpretation and translation of the terminological and semantic relationships within domains of interest but it is still unclear how they can be applied in the context of multimedia data. In this paper, we describe a framework which can capture and manage semantic information related to the multimedia data by modeling in the ontology their features. In particular, the proposed ontology-based framework is organized in the following way: at the lower levels, spatial objects, colors, shapes are represented, and semantic relationships can be established among them; at the higher levels, objects with semantic properties are put into relationship among themselves as well as with the corresponding low-level objects. On this basis, we have designed an ontological system particularly suitable for image retrieval. We have also taken into account the inherent uncertainty related to the representation and detection of multimedia properties in this complex domain. Along this work, we have provided examples from the image domain; moreover, since ontologies provide a semantic means for the semantic comparison of objects and relationships across different formats, the system is easily extensible to other, heterogeneous data sources.

The new vision of the Web as a global intelligent repository needs advanced knowledge structure to manage complex data and services. From this perspective, the use of formal models to represent information on the web is a suitable way to allow the cooperation of users and services. This paper describes a general ontological approach to represent knowledge using multimedia data and linguistic properties to bridge the gap between the target semantic classes and the available low-level multimedia descriptors. We choose to implement our approach in a system to edit, manage and share multimedia ontology in the WEB. The system provides tools to add multimedia objects by means of user interaction. The multimedia features are automatically extracted using algorithms based on standard MPEG-7 descriptors.

Streszczenie:

Purpose – The overwhelming speed and scale of digital media production greatly outpace conventional indexing methods by humans. The management of Big Data for e-library speech resources requires an automated metadata solution. The paper aims to discuss these issues. Design/methodology/approach – A conceptual model called semantic ontologies for multimedia indexing (SOMI) allows for assembly of the speech objects, encapsulation of semantic associations between phonic units and the definition of indexing techniques designed to invoke and maximize the semantic ontologies for indexing. A literature review and architectural overview are followed by evaluation techniques and a conclusion. Findings – This approach is only possible because of recent innovations in automated speech recognition. The introduction of semantic keyword spotting allows for indexing models that disambiguate and prioritize meaning using probability algorithms within a word confusion network. By the use of AI error-training procedures, optimization is sought for each index item. Research limitations/implications – Validation and implementation of this approach within the field of digital libraries still remain under development, but rapid developments in technology and research show rich conceptual promise for automated speech indexing. Practical implications – The SOMI process has been preliminarily tested, showing that hybrid semantic-ontological approaches produce better accuracy than semantic automation alone. Social implications – Even as testing proceeds on recorded conference talks at the University of Tebessa (Algeria), other digital archives can look toward similar indexing. This will mean greater access to sound file metadata. Originality/value – Huge masses of spoken data, unmanageable for a human indexer, can prospectively find semantically sorted and prioritized indexing – not transcription, but generated metadata – automatically, quickly and accurately.

Information management includes multimedia data management, knowledge management, collaboration, and agents, all of which are supporting technologies for XML. XML technologies have an impact on multimedia databases as well as collaborative technologies and knowledge management. That is, e-commerce documents are encoded in XML and are gaining much popularity for business-to-business or business-to-consumer transactions. Recently, the internet sites, such as e-commerce sites and shopping mall sites, deal with a lot of image and multimedia information. This paper proposes an intelligent web digital image information retrieval platform, which adopts XML technology for social curation commerce environment. To support object-based content retrieval on product catalog images containing multiple objects, we describe multilevel metadata structures representing the local features, global features, and semantics of image data. To enable semantic-based and content-based retrieval on such image data, we design an XML-Schema for the proposed metadata. We also describe how to automatically transform the retrieval results into the forms suitable for the various user environments, such as web browser or mobile device, using XSLT. The proposed scheme can be utilized to enable efficient e-catalog metadata sharing between systems, and it will contribute to the improvement of the retrieval correctness and the user’s satisfaction on semantic-based web digital image information retrieval.

The integration of multimedia technology and foreign language teaching has gradually become a contemporary key research topic under the trend of the integration of modern information technology and education. As an emerging method, multimedia-assisted learning method can not only create a more realistic language learning environment but also make contributions in stimulating students’ willingness to learn and improving educational effects. However, sometimes it is used improperly, this method can easily lead to the teaching form being larger than the content, and the teaching effect may not be satisfactory. This article focuses on the characteristics of the professional English teaching model based on wireless network communication and multimedia, discusses the practical application of wireless network communication and multimedia technology in professional English teaching, and conducts a simple research on the professional English teaching model. Taking the professional English teaching model and the traditional multimedia teaching model of English as the research objects, two natural students are selected as the research objects, and they are divided into the experimental group and the control group. Statistical software is used to analyze the data in detail. The test results of the experimental class and the control class were analyzed before and after the experiment. The experimental results show that the professional English teaching model based on wireless network and multimedia has a significant teaching effect compared with the traditional English teaching model. Comparing the experimental group and the control group, English scores improved by 11%. The gap between the two groups is very obvious. As far as the scores of each part of the English test paper are concerned, the scores of each part of the experimental group are also higher than those of the control group. The professional English teaching model based on wireless network communication and multimedia turns out to be effective and popular among students.

The purpose of this paper is to explain why object oriented data modeling is more popular than relational data modeling. A data model is a logic organization of the real world objects (entities), constraints on them, and the relationships among objects. Relational model is very simple since data in represented in the form of relations that are depicted by use of two-dimensional tables. Rows in the table represent records and Columns represent attributes of the entity. The basic concept in the relational model is that of a relation. In object-oriented model main construct is an object. As in relational model, there are relations similarly we have objects in OO data modeling. So first thing in OO model is to identify the objects for the systems. Examining the problem statement can do it. Other important task is to identify the various operations for these objects. It is easy to relate the objects to the real world entity. The object-oriented approach has proved to be especially fruitful in application areas, such as the design of geographical information systems which have a richly structured knowledge domain and are associated with multimedia databases. Relational data modeling is different from Object Oriented data modeling because it focuses solely on data while object oriented data models focuses on both the behavior and data aspects of your domain. OODBMS are faster than relational DBMS because data isn’t stored in relational rows and columns but as objects. Objects have a many to many relationship and are accessed by the use of pointers.

This theme focuses on representing and reasoning high-level semantic based on concepts and their space relations. As to multimedia data, such as image and video, acquiring, representing and retrieving high-level semantic information has been a confused problem for a long time. Without the support of knowledge database, it is an impossible mission to carry out the simple synonymous retrieval, let alone retrieving the abstract semantic. This paper proposes some algorithms to translate restored concepts and their relations into a Concept Semantic Network, which is visualized by SVG finally. The paper also introduces the method of recording concepts distribution by description logic, which services users with concepts and distribution retrieval.

The Earth Mover's Distance (EMD) is one of the most-widely used distance functions to measure the similarity between two multimedia objects. While providing good search results, the EMD is too much time consuming to be used in large multimedia databases. To solve the problem, we propose an approximate k-nearest neighbor (k-NN) search method based on the EMD. In the proposed method, the overhead for both disk accesses and EMD computations is reduced significantly, thanks to the approximation. First, the proposed method builds an index using the M-tree, a distance-based multi-dimensional index structure, to reduce the disk access overhead. When building the index, we reduce the number of features in the multimedia objects through dimensionalityreduction. When performing the k-NN search on the M-tree, we find a small set of candidates from the disk using the index and then perform the post-processing on them. Second, the proposed method uses the approximate EMD for index retrieval and post-processing to reduce the computational overhead of the EMD. To compensate the errors due to the approximation, the method provides a way of accuracy improvement of the approximate EMD. We performed extensive experiments to show the efficiency of the proposed method. As a result, the method achieves significant improvement in performance with only small errors: the proposed method outperforms the previous method by up to 67.3% with only 3.5% error.

AbstractDue to its wide range of applications, the impact of multimedia in the real world has shown stupendous growth. Texts, images, audio, and video are the different forms of multimedia which are utilized by humans in various applications such as education and surveillance applications. A wide range of research has been carried out, and here in this paper, we propose an object racking with the aid of rough set theory in combination with the eminent soft computing technique evolutionary programming. Initially, the input video is segregated into frames, then the frames that belong to particular shots are identified through the shot segmentation process, and after that the object to be tracked is identified manually. Subsequently, the shape and texture feature is extracted, and then the rough set theory is applied. This is done to identify the presence of object in the frames. Consequently, genetic algorithm (GA) is utilized for the object monitoring process to mark the object with variant color. As a result, the selected object is tracked in an effective manner.

The overall development of technology has also contributed to the development of multimedia technology and its greater application in education. The curriculum cannot be viewed separately in relation to the changes taking place in modern society and in relation to its technological progress. Teaching methods, techniques and tools are constantly changing and in modern pedagogy they are more efficient and stimulating for the acquisition of knowledge. In traditional teaching, the role of teachers and students differs significantly, the teacher has a dominant role of lecturer, while students have a passive role in the process of acquiring knowledge. Teaching conceived in this way changed with the development of technology, because the teacher is no longer the only source of knowledge and information, and students are not passive objects that absorb that knowledge. Our goal is to review the importance and efficiency of multimedia education by reviewing the relevant literature. As first, we will try to define the concept of multimedia and analyze the theoretical basis of multimedia education, as well as its application in teaching. We start from the assumption that since technology simplifies functioning in general, it contributes to simplifying and improving the education process.

These applications are useful not only as presentation tools, but also as supplementary instruction, whereby a student can interact with an application at his/her own convenience and learning level. “Interactive Lessons for Introductory Horticulture©” is one example of an application used in OSU's HORT 1013: Principles of Horticultural Science course. Students are able to navigate to various topics by selecting chapters and topics within chapters. The information is not just presented, but rather acted upon by the student through movable objects, touch-sensitive areas, text, audio and video clips, etc. Student learning should be enhanced by the variety of stimuli and the ability to review an entire presentation or portion thereof at will.

One of the major concerns throughout the world today is to make high quality health care available to all. Traditionally, part of the difficulty in achieving equitable access to health care has been that the provider and the recipient must be physically present in the same place. Recent advances in Information and Communication Technologies have increased the number of ways health care can be delivered to reduce these difficulties. Mobile phones are the most commonly used devices in today’s scenario. The expanding use of mobile phone, telecommunication companies added feature such as MMS (Multimedia Messaging Service) in order to attract more customers. The Multimedia Messaging Service (MMS) has became very popular for sending messages containing multimedia objects such as images, audio, or video clips among mobile users. Alongside, the need for the secure communication became more imperative. Steganography is the most reliable technique for hidden communication. Hiding information, especially in images has been an alternative solution for secret communication [2].

Recently, there has been an increasing interest in building question answering (QA) models that reason across multiple modalities, such as text and images. However, QA using images is often limited to just picking the answer from a pre-defined set of options. In addition, images in the real world, especially in news, have objects that are co-referential to the text, with complementary information from both modalities. In this paper, we present a new QA evaluation benchmark with 1,384 questions over news articles that require cross-media grounding of objects in images onto text. Specifically, the task involves multi-hop questions that require reasoning over image-caption pairs to identify the grounded visual object being referred to and then predicting a span from the news body text to answer the question. In addition, we introduce a novel multimedia data augmentation framework, based on cross-media knowledge extraction and synthetic question-answer generation, to automatically augment data that can provide weak supervision for this task. We evaluate both pipeline-based and end-to-end pretraining-based multimedia QA models on our benchmark, and show that they achieve promising performance, while considerably lagging behind human performance hence leaving large room for future work on this challenging new task.

AbstractThe increasing costs of health care and the economic reality has produced an interesting paradox for the health professional to perform more clinical work with fewer support personnel. Moreover, an explosion of the knowledge-base that underlies sound clinical care not only makes effective time management critical, but also knowledge management compelling. A multimedia workstation is an electronic assistant for the busy health professional that can help with administrative tasks and give access to clinical information and knowledge networks. The multimedia nature of processed information reflects an evolution of medical technologies that involve more and more complex objects such as video sequences or digitized signals. Analysis of the 445 Medline-indexed publications for the January 1991 to December 1994 period, that included the word “workstation” either in their title or in their abstract, helps in refining objectives and challenges both for health professionals and decision makers. From an engineering perspective, development of a workstation requires the integration into the same environments of tools to localize, access, manipulate and communicate the required information. The long-term goal is to establish an easy access in a collaborative working environment that gives the end-user the feeling of a single virtual health enterprise, driven by an integrated computer system when the information system relies on a set of heterogeneous and geographically distributed components. Consequences in terms of migration from traditional client/server architectures to more client/network architectures are considered.

As a large number of the multimedia information emerges, the cross-media retrieval system becomes an important research focus. The cross-media retrieval system is based on the traditional content retrieval, extracting color, texture, and shape features vector of the images. A new method was carried out in this paper. Firstly, the uniform semantic representational framework was built to organize the different mode media heterogeneous characteristics. Secondly, the Ontology database representing each type of media concepts was set up. The Ontology database organizes the low level features of the multimedia objects to associate multimedia files in the semantic level. Thirdly, the cross-media retrieval algorithm based on ontology was introduced. The results of the experiment showed that this cross-media retrieval method based on the Ontology was more effective and accurate.

numbers, short text, and dates. With the advent of powerful and affordable multimedia computers, people increasingly need databases to store more complex objects. Typical objects include graphics, sound, and video clips. For some applications, like geographic Information Systems(GIS) and computer-aided design (CAD), developers need the ability to define their own objects.Storing objects involves two aspects: storing data for their properties and storing and activating theirmethods. The first part- storing properties – is relatively easy. In relational database, the properties becomes columns. Relational databases can be adapted to handle objects. On of main components is the ability to define new data types. These data types are treated as objects, and they can inherit properties from other data types. Many commercial applications are created using OO methodologies. Given that several object-oriented applications might need to share the same data, we describe how such applications can interoperate with eachother. By exposing the internal object properties and methods, the developers can use the applications to create the complex integrated business applications. The applications can use all the features of a spreadsheet, word processors, or graphics packages.This technology also provides function as well as data together so that the data can be manipulated bythe given function. we show that how the data is more secure in object-oriented database than in relational database and also why do we migrate from RDBMS into OODBMS.In this paper, we describe the major characteristics and requirements of object-oriented applications and how they may affect the choice of a system and method for making objects persistent in that application.

Classrooms are radically changing across the nation's campuses. Rooms that were once dominated by bright lights, chalkboards, and overhead projectors are being transformed into multimedia “Master Classrooms,” complete with task lighting, video projectors, visualizers, laserdisk and videotape players, soft boards, and computers. What are these pieces of equipment, how much do they cost, and how can they be implemented into horticultural curriculum? Just as our college students teethed on television programs such as Sesame Street when they were toddlers, they now are continuing to learn through a combination of audio, video, and kinesthetic stimulation in the classroom. Computer hardware and software empowers today's educator with a multimedia development studio on his/her desktop to create simple “slide” presentations or complex, interactive multimedia applications. However, it is not multimedia itself, any more than it was the chalkboard, that makes a powerfully educational presentation; rather it is the educator's creativity, utilization of instructional methods, and delivery. Interactive, multimedia development software allows the educator to address different styles and paces of learning as he or she develops a lesson. Through on-screen hot spots, movable objects, buttons, etc., the educator engages the learner's attention and provides the opportunity for the learner to rehearse a concept as often and repeatedly as necessary to encode the information for later retrieval and application to new concepts. Given the power of this new medium to visually and audibly present information, how does the educator avoid overloading the learner? Although multimedia applications readily engage the learner, it takes careful programming by the educator to maintain and direct the learner's attention to ensure transfer of the information from short- to long-term memory.
