Multimedia Development & Design  Definition - Multimedia Multimedia: Combination of text, graphics, sound, animation and video (forms of media) delivered by computer.  Definition - Multimedia Multimedia Developers: people who create multimedia projects. Multimedia Projects: multimedia materials, that are part of a particular topic or subject, presented on a computer or television screen. What / Where Multimedia Usages?  Multimedia Usages Business – Communication: Voicemail, video conferencing. – Marketing & Sales: Presentations, advertising, product demos, online catalogs. – Training: Interactive training programs, simulations (mechanics learning engine repair).  Education / Schools – Empowering students: explore beyond traditional teaching, taking charge of their learning. – Shifting teacher roles: to become guides and mentors, rather than simply delivering information. – Courseware / Simulations: e.g medical simulations with case presentations for healthcare professionals. – Information searching  Public Places – Location: Available in hotels, train stations, shopping malls, museums, and grocery stores. – Purpose: Provides information and assistance via stand-alone terminals or kiosks. – Advantages: – Reduces the need for traditional information booths. – Operates 24/7, offering help outside of regular hours. – Examples of Services: – Supermarket Kiosks: – Hotel Kiosks:  Home – Television – Satellite TV – SMS services (chats, voting) Entertainment – Games – Movies – Video Multimedia Requirements 1- Creative skills Graphic design, Storytelling , Audio & Video production 3- Technology & Tools Adobe Photoshop, Multimedia Flash..etc 2- Organization and business talent Project Management, Communication Skills  What are the Advantages and disadvantages of Multimedia?  Advantages of Multimedia 1. Enhances Text Messages Adds interesting sounds and eye-catching visuals 2. Better Than Traditional Presentations More attractive than simple slide shows 3. Grabs and Keeps Attention Combines text, audio, graphics, and video to maintain interest 4. User-Friendly Easy to use, even for people uncomfortable with computers 5. Both Fun and Educational Makes learning more enjoyable 6. Interactive Allows users to click, explore, and participate  Disadvantages of Multimedia 1. Expensive 2. Not always easy to configure 3. Requires special hardware 4. Not always compatible  Multimedia Categories 1. 1- Linear Multimedia is: - Not interactive - User have no control over the content that is being showed Example: Movie, Non interactive lecture / demo show 2- Non-Linear Multimedia is: - Interactive - User have control over the content that is being showed - Users can given navigation control Example: Games, Interactive CD  Linear vs Non-Linear Presentations Aspect Linear Non-Linear Path Sequential Flexible Control Presenter-driven Audience-driven Structure Fixed order Interactive, choose own path Adaptability Low High Formal, informational Interactive sessions, Suitability sessions exploratory learning Ease of Requires more planning to Easier as it follows a set path Preparation allow for choices Linear Presentations Advantages Disadvantages Predictable, Every audiences see Not interactive. They cannot change same Presentation the order of presentation Timing of presentation is predictable Can be boring as the audience may have to view the slides that happens to be irrelevant to them. Nonlinear Presentations Advantages Disadvantages Slides can be accessed in any More complicated order Users can go both forward and Harder to predict the timing of backward through the slides presentation Can provide presentation that meets the needs of individual users Improved Interactivity The presenter can use same presentation for different audience's Match Linear or Non-Linear Linear Non-Linear  Last Class Review https://quizgecko.com/learn/characteristics-of- multimedia-systems-rn50pc/play?qsid=1070774  Multimedia System “A system capable of processing multimedia data and applications”. Characterized by: 1. The processing 2. Storage 3. Generation 4. Manipulation 5. Delivery Multimedia information. 4 Characteristics of a Multimedia System Must be Must be computer represented controlled. digitally. interactive interface of Integrated. the final presentation  1- Computer Controlled Producing the information content using authoring tools, image editor, sound and video editor Storing info providing large and shared capacity for multimedia info. Transmitting info through network. Presenting info to end user use of computer peripheral such as display device (monitor) or sound generator (speaker).  2- Integrated All multimedia components (audio, video, text, graphics) used in the system must be somehow integrated. Every device (microphone and camera) is connected to and controlled by a single computer. A single type of digital storage is used for all media types. Video sequences are shown on computer screen instead of TV monitor.  3- Interactivity Level 1: Interactivity strictly on information delivery. Users select the time when the presentation starts, order, speed and form of the presentation itself. Level 2: Users can modify information content (modification is recorded). Level 3: Actual processing of users input and the computer generate genuine result based on the users input.  Digitally Represented Digitization: process involved in transforming an analog signal to digital signal. Components of a Multimedia System 1.

Turn real-world sounds and images into computer-readable There are 3 aspects of the digital audio video operation: 1. Capture-raw the original signal 2. Storage-Files digitally 3. Play it back by converting it to an understandable format  Multimedia Software There are 2 Classes of software that make desktop software and multimedia products: 1) Executables: completely self-contained executable programs that provide all functionality of a particular application. 2) Libraries: often called dynamic link libraries.  Multimedia Application? “Any computer application that contain or use Multimedia elements”. ‫ة أو‬ like a movie or a book. Content must be created and produced. Usually, interactive.  Examples of Multimedia Application World Wide Web Hypermedia courseware Computer-based Training (CBT) Interactive TV Computer Games Virtual reality Multimedia Database systems  Delivering Multimedia 1- Optical disk (CD-based) The most cost-effective method of delivery for multimedia materials. Store large amounts of some combination of text, graphics, sound, and moving video. 2- Over a distributed network (Web-based) Suitable for web-based content eg. website Files need to be compressed before transfer  Web-based CD-based Limited in picture size and low Can store high end Multimedia video resolution elements Can be changes, damaged or Can be permanently stored and not deleted by irresponsible individuals changeable Information can be updated easily Information can be quickly and cheaper outdated Summary Quiz  Reference Multimedia Technology & Applications, David Hillman,1997,First edition, Delmar Cengage Learning ,ISBN-13: 978-0827384989
