  1. Chapter 2Products and Evaluation Multimedia Products They come in many shapes and forms. In order to develop multimedia products, you need to know what types are out there • Types of multimedia products • The type of product is defined by who is using it • Ex: use of CD-room based encyclopedia

  2. Multimedia types depending on their uses are grouped as: Briefing Reference Database Education and Training Kiosk Entertainment and games Some of the products may overlap each other. Example: A child playing a computer game

  3. Multimedia Products: Briefing • Briefing products are small, straightforward, linear products used to present information quickly and concisely • Characteristics of Briefing Products • Developed in short period of time • Short lifetime • Text is the predominant media used • Briefing Products Examples • Corporate presentations • Sales presentations • Educational lectures

  4. Briefing contains few navigation controls. Other control types are used to enhance the presentation such as the following: • Zooming • Panning control • Thumbnail pages or bookmarks (for review, select, move) • Drawing and graphic editing tools • Characteristics of good Briefing products: • A thorough understanding of the subject • Seamless integration of content • Consistent page layout • The briefing presenter should speak Extemporaneously about the presentation

  5. Multimedia Products: Reference • They are the most common type of commercial multimedia products. • Examples of Reference products • Encyclopedias • Dictionaries • Cook-books • Historical and scientific surveys • Characteristics of Reference products • Long lived products • Usually deployed on CD-ROM or other high-density media • Developed and used by a wide range of users • Very structured and easy to use

  6. Types of Reference products • Generalized content • Detailed content (specialized) • Multimedia Products: Database • Similar to reference systems in having large amounts of data • Different because they are focused on storing and accessing the actual data • Examples: • Collections of fonts, pictures, sound and video clips • Materials of plays, stories • Map, chart • Scientific survey information • Phone number and zip code listings

  7. May require multiple disks/CDS to store large amount of data • It depends on support functions such as: • A search and find engine • Presentation functions to display the data nicely • Export functions • Print facilities • Conversion utilities • The type of the support functions will vary depending on the expected use of the product

  8. Multimedia Products: Education and Training • They fall in three general categories • Instructor support products • Standalone or self-paced products • Combination products • Instructor support products • Used by teachers and trainers (with textbooks, lectures,..) • They may include study notes, lectures slides and handouts and testing and assessment materials • Standalone products • Called CBT (Computer Based Training) • Can be used alone by the students

  9. Combination products • Combine of support and standalone products • Example is textbooks that have CD-ROMs • Three important things must be considered when building Education and Training products: • The background of the students • The learning objective and outcome of the training • Assessment (testing) of the students to make sure that they have learned something

  10. Multimedia Products: Kiosk • Kiosk products are easy to use and have a relatively simple function (ex. ATM bank machines, mall ) • They are entertaining, utility and workhorse • They are unique in that they consist of software and hardware solutions • They usually consists of top-level menu with no more than two or three layers of sub-menus • A timing mechanism to reset the kiosk to a starting point when it is unused

  11. Multimedia Products: Entertainment and Games • They are the most popular especially for those who never used computer • They may be accessed on a standalone computer via CD-ROM, networks or special purpose game machine connected to television monitors • Heavily based on the use of graphics, audio, animation and video • Have simple navigation controls • Most of them depend on a timer or scorekeeping system • Offers multi player feature

  12. Evaluation • There are 2 perspectives for evaluation of multimedia products, the user and the developer • The User’s perspective • Issues concern the user are: • Subject/content • Platform • What type of platform and the compatibility with the product • Usability • How well the product works and can the user operate it • Learning/training time • Error rate • Task time • Retention :operating the product in future sessions • Look and feel • Cost • How much is gained for how much is spent

  13. The Developer’s perspective • Evaluation by other developers • Will not repeat mistakes • Issues to be considered during the development process • Content • Product domain • Message • Comparison to other similar products • Performance • Behavior on the end user hardware • Graphic quality • Audio and video playback quality

  14. Delivery • Installation • Operational features • Packaging • Documentation • Interface • Ease of use for novice users • Depth for experienced users • Navigation features all work and useful • Strategies for new Developers
