New Textbook Review

 

I am currently researching the possibility of publishing a new text on Multimedia by Anton Eliens, and am keen to receive feedback from lecturers who are currently teaching in these areas. Many thanks, therefore, for agreeing to help with my research. Below are listed the questions I would like you to answer.

 

A report following the headings listed below would be ideal. If you would please avoid answering “yes” or “no” to individual questions, and answer all questions as fully as possible, I would be very grateful.

 

As far as length is concerned, I would hope to receive approximately five sides of typed A4. Can I please remind you that the deadline for this review will be Friday, 21st May 2005.

 

Please contact me if you have any queries or require any further information. My direct telephone number is: 020 7067 2584. My address is:

Definition and Teaching

  • How is Multimedia taught at your university?

Multimedia Systems is a Part III single semester module.

  • Is there a degree awarded in Multimedia?

You can do a degree or Masters in Computer Science with Image and Multimedia Systems.

  • Please describe the technical background of your student cohort for this subject.

Students will typically be 3rd year BSc students with a solid grounding in computer science theory.

  • How many specialist multimedia modules are offered? How many students enrol on each module and are they core or optional?

There is one 3rd yr option which is chosen by between 40-80 students a year (30-60% of the year group)

  • What are the foundational principles of this topic and key subtopics and themes

Our aim is to provide a broad overview of the area re-inforced by private study on a specific topic. For the purposes of the course we loosly divide the field into the following four themes (Multimedia Networking, Multimedia Storage, Distributed Information Systems and, Applications and Content Creation).

  • Of the multimedia modules on offer at your institution, please describe the balance between theoretical content and practical implementation and indicate in which module (if at all) there is a greater emphasis on principles.

The students are expected to write a research paper on one aspect of Multimedia Systems. These can range from technical briefings of a technology to discussions of social issues. The course is designed to cover a range of material from theory and philosophy through the practical issues and technical details.

  • What principles of multimedia do you teach and how stable do you feel these to be?

One of the core principles seems to be discussing how the field relates to and overlaps with other areas of computer science. It is a difficult subject to pidgeon hole, not least because there are many working definitions.

  • How do you see this subject developing over the next few years?

It’s difficult to think of it as just one subject. As will become apparent from my answers below, often it will be defined by which  other courses run alongside it. It is such a broad topic that it can cover a multitude of things. I suspect more chunks will break off and form their own areas. DigitalBroadcasting for instance could easily occupy a course on its own and many of the interface issues raised in multimedia systems are being tackled by the HCI community and the Ubiquitous Computing community so drawing lines will always be a temporary thing.

  • What technologies and applications are used for practical work?

Students can use whatever technologies they choose depending on the nature of the topic they have chosen. Only a subset will do practical work but they range from implementing steganography algorithms through to setting up VOIP systems.

  • Which are the most popular themes amongst your students:
    • Visual design

Not included on the course. A graphic design or art department would be better candidates to teach it. We do have a Computer Graphics module and elements might be covered on the HCI course.

    • Audio and Music

Very popular with students, included VOIP and standards such as MusicXML. Digital rights issues are also heavily debated.

    • Animation

Again, not specifically taught. This seems to be a combination of Computer Graphics (taught elsewhere) and Animation (best taught by artists). Tools for creating animations could be chosen but not the process itself.

    • Usability

Usability can be considered for any multimedia system. Usability as a concept would not be gone into in depth, the HCI module includes this.

    • Hypermedia

Hypermedia has its own module at Southampton as does Web Technologies. This is one of the School’s strengths. Hypermedia has been chosen by students on the Multimedia Course, but they have to focus on the multimedia aspects, it is not multimedia in itself.

    • Other (please specify)

Social factors are a strong influence here. Many multimedia systems raise issues to do with Privacy, Rights Management, Ethics and also have social impacts in terms of changing how people live their lives. The students will often look at these aspects for example discussing how technologies like MSN Messenger have changed how people communicate over distances.

 

 

General

  • How clear, concise and accessible is the writing style? How well is the subject explained?

The writing style is not very clear. Despite claiming to be academic I found lots to be very opinionated and vague, often straying into hyperbole. The grammar would need strong editing to provide an easy reading experience.What are presented as definitions often turn out to be opionions or even inaccurate potrayals. ‘virtual reality (is) when and where the computer disappears and you become the ‘ghost in the machine’ is one of the worst definitions I’ve come across.

  • How logical and relevant is the book’s structure and table of contents?

I found the inclusion and ommisions in the table of contents to be quite puzzling. Admittedly not having read all the chapters I was unable to see how distinctions were drawn between Information Spaces, Information Systems Architecture and Digital Content Creation. Topics such as hypermedia and Virtual Environments have been written about extensively elsewhere and without a strong tie in to a central message seem to be just two examples out of any number that could have been chosen. Chapter 4, masquerading under the guise of Multimedia Platforms, is actually a tutorial of DirectX 9 SDK that would make an appendix to a Computer Graphics book and anywyay would be out of date before the book reached the printers.

  • How well are the core topics covered in the book? How could any of them be improved?

I didn’t feel that any core topics were covered. The chapters disolved into specific technical examples almost instantly. What’s worse, the introduction left me with no clear idea as to what the author thinks multimedia is other than the idea of digital convergence.There is no one definition of multimedia, it will depend what field you work in and what perspective you are taking. To not tackle this is a major oversight. Application development appears to be a coursework and not a chapter with an information content. Multimedia networking appears to be absent and there seems to be very little evidence of social implications.

  • Are there any topics that you would remove?

As I said above, some sections will be covered in more depth in books specifically about those topics. Without a conceptual overviewing tying them into multimedia systems topics such as VR, hypermedia and Computer Graphics i.e. DirectX 9 could easily be left out.

  • Are there any topics that you would add?

Multimedia Networking, History of Multimedia, Social Implications, a proper (accurate) chapter on communications theory. Rather than go into too much detail here, I found and have pasted below the call for papers from this years Multimedia conference. This is what the Multimedia Research community believes are interesting topics in the field of multimedia systems today. It is interesting to compare this list with the contents page of the manuscript.

 

Multimedia analysis, processing, and retrieval, including multimedia semantics, aesthetics, modeling, assimilation/fusion, audio/video/multi-modal processing, multi-sensor processing, multimedia content description and indexing, multimedia digital rights management (protection and attribution), content-based retrieval with emphasis on multiple and novel media.

 

Multimedia networking and systems, including context-aware multimedia communications, Internet telephony, peer-to-peer streaming, audio/video streaming, multimedia content distribution, wireless multimedia, adaptive support for scalable media, Internet protocols, multimedia servers, operating systems, middleware and QoS.

 

Multimedia tools, end-systems, and applications, including new UI metaphors, usable distributed collaboration, authoring, multi-modal interaction and integration, multimedia in e-learning, entertainment, personal media, assisted living, and virtual environments.

 

 

Pedagogical features

  • How useful are the examples? How well do they highlight key issues in the text? How could they be improved?

I found the examples to be at best distracting and at worst incomprehensible summaristions of niche areas of research (I’m thinking ‘VR for pain relief’ here). The authors tendancy to take examples from the City where he lives and his own work make the book seem very parochial and insular. There are countless better example out there that could have been chosen. An example is also only good if it has a point to illustrate and too often no concept was clearly presented in the first place.

  • Please offer suggestions for any examples or case studies of multimedia projects, relevant to the scope of the book, that you would like to see included in this book and which you think would be particularly appealing to your students.

This is difficult to answer as I’m left unsure as to what concepts the author is trying to communicate.

  • How useful are the other pedagogical features: Learning Objectives, Case studies, Future Directions, Quick Exercises, and Longer Exercises?

I’m not sure I agree with the idea of having learning objectives at the start of chapters. Learning objectives will always need to be tailored to courses (and students), they will vary across education systems, and it suggests that the material can only be used to get across specific ideas. Perhaps suggested learning objectives could be provided for teachers seperately. Having said that, ‘You should be able to … recount the history of digital entertainment.’ (Chapter 1) Is not an achievable learning goal by any stretch of the imagination. Even if any history of digital entertainment were offered in the chapter, which it isn’t! The questions were weak reflections of the learning objectives, the case studies were so embedded in the course taught at the author’s instituation so as to be incomprehensible, the future directions were at best a single random research area.

  • Do the illustrations motivate and make the content come alive?

If I’m honest, no. With no captions it was unclear why they were there. I’m also not sure why ‘the artwork’ is described in the preface. Surely this is a note to the editor at best.

  • Should there be more, or less, or are there sufficient?

There should be less pictures from the author’s ‘personal’ collection and more images that actually illustrate something. And the text should say why they’re there.

  • Should the visual impact of this manuscript be improved? If so, please suggest in what ways.

I’m assuming that the manuscript in the form sent to me was typeset by the author? There were numerous problems, captions missing, case issues, floating headings, etc. To be honest though, if the content isn’t right then that’s a side issue.

  • What do you think of the overall pedagogical approach for the book? How well is the teaching and learning process enhanced?

I’m not sure it’s enhanced at all. If anything, the constant cramming in of material from the author’s own course only serves to undermine any efforts a lecturer might make to use the book for their own cohort. If someone wants to pick up an entire course off the shelf then the learning approach, goals, assessment, evaluation and general methodology need to be articulated in a far more comprehensive manner.

 

Supplements

  • What web resources would be useful with a Multimedia textbook, both for lecturers and for students?

I’m always wary of supplementals, they often make people feel the book doesn’t have to stand entirely on its own. If someone is going to maintain it, then a portal site that has links to interesting reading, projects, additional material might be useful but they go out of date very quickly. One of the urls listed in the manuscript already doesn’t exist and it’s still at the review stage.

  • Are there any essential or value added electronic components that we should consider including on CD-ROM/DVD?

Not that I can think of.

 

Competition

§         What other Multimedia textbooks teach principles rather than/as well as practice?

Principles of Interactive Multimedia,  Mark Elsom-Cook

§         What are the main text(s) used to teach this subject? (Please list author, title, and publisher)

Digital Multimedia,  N. Chapman, J. Chapman

§         Which of these books do you use yourself? Why did you choose it and what would make you change to another textbook?

I don’t use either as the nature of our course is that there is no core-text and students are encouraged to reasearch specific topics themselves and gain an overview from reviewing and reading each others work.

§         What are the real strengths and weaknesses of the main competing texts (content, pedagogy, design, supplements)? Please list 4 or 5 key points.

§         Do they take a significantly different approach to Eliens?

§         What pedagogical features do they include? How well do these aid teaching and learning?

§         In what ways is Eliens strong compared to these books? (If possible, please list 5 key points.)

§         In what ways is Eliens weak compared to these books? (If possible, please list 5 key points.)



Summary

  • Please tick which title you feel is most appealing and best describes the approach of this book:

An Introduction to Multimedia Authoring

What is Multimedia?       No answer is given to this question!

The Essence of Multimedia

Or provide your own suggested title……A personal perspective on Multimedia

………………………………………………….

§         What do you feel would be the main market for this book?

Students attending the author’s own course on Multimedia

§         Would you use this book as a textbook for your course(s)?

Not a chance.

§         If so, what could make this a required, set book for your course?

§         What improvements/changes are mandatory for publication?

I’m not sure where to start. It needs to have a coherent approach. It needs to define multimedia in something other than one narrow research based categorisation. It needs the communications studies sections to be reviewed by someone that understands the topic to at least A-level standard.

§         What other enhancements would you (ideally) like to see?

Incremental changes are not going to be enough.

§         What would you identify as the key strength(s) of this manuscript?

If you want to write a 3D shader using DirectX9 in the next year then Chapter 4 is for you.

§         Given the above, please rate the strength of this book proposal, assuming that this draft will be modified and refined in the light of technical editing and reviewer feedback:

1 = not suitable for publication     

------------------------------------------------------

2 = average but requiring major modifications

3 = good background on Multimedia and could be useful on my course

4 = strong coverage, will recommend to my students

5 = excellent, will set as required textbook

 

Please indicate whether you would like to review more chapters from this manuscript as and when they have been developed.

Given my views stated above, I can’t see any more chapters changing my view on this manuscript. Also, as my main research area is Hypermedia, the thought of reading Chapter 2 fills me with dread.

 

This is the end of your review. Very many thanks again for your time and feedback.

 

I can only apologise if my review appears unduly harsh, however, I was disturbed by quite how poor this manuscript is. I was also slightly surprised that it has even gone out for review by domain specific reviewers. Even someone with no knowledge of the field would find this an uncomfortable and uninformative read. I could almost see the author gathering his lecture notes, research papers, last years courseworks and contents off his random pinboard of interesting applications to mash together  to prepare this book. I suspect an incremental approach may not be enough here, the author needs to sit down and think about what multimedia is for everyone and not just tell his own personal experience of the field, which is, I’m afraid, what we have here.
