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 Interactive, choose own Structure Fixed order path Adaptabilit Low High y Formal, informational Interactive sessions, Suitability sessions exploratory learning Ease of Easier as it follows a Requires more planning Preparation set path to allow for choices Linear Presentations Advantages Disadvantages Predictable, Every audiences Not interactive. They cannot see same Presentation change the order of presentation Timing of presentation is Can be boring as the predictable audience may have to view the slides that happens to be irrelevant to them. Nonlinear Presentations Advantages Disadvantages Slides can be accessed in More complicated any order Users can go both forward Harder to predict the and backward through the timing of presentation slides 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  Multimedia System  Multimedia System is 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 ‫يجب أن يتم التحكم فيها بواسطة‬.‫الكمبيوتر‬.‫يجب أن يتم تمثيلها رقميا‬.‫مدمج‬ Must be Must be ‫واجهة تفاعلية للعرض النهائي‬ comput represe er nted controll digitally ed.. interacti ve interface Integrat of the ed. final presentat ion  Computer Controlled Producing the content of the information – e.g. using ‫أدوات‬ the authoring tools, image editor, sound and video editor ‫فيديو‬ Storing the information – providing large and shared ‫مشتركة‬ capacity for multimedia information. Transmitting the information – through the network. – ‫رفية‬ Presenting the information to the end user – make ‫و مولد‬ direct use of computer peripheral such as display device (monitor) or sound generator (speaker).  Integrated ‫دة‬ All multimedia components (audio, video, text, graphics) used in the system must be somehow integrated. ‫يه‬ Every device, such as microphone and camera is connected to and controlled by a single computer. A single type of digital storage is used for all media type. Video sequences are shown on computer screen instead of TV monitor.  Interactivity Level 1: Interactivity strictly on information delivery. Users select the time at which the presentation starts, ‫يل‬ ‫ت‬ the order, the speed and the form of the presentation ‫ض‬ itself. ‫كله‬ ‫أو‬ Level 2: Users can modify or enrich the content of the ‫هذا‬ information, and this modification is recorded. ‫يل‬ ‫الت‬ Level 3: Actual processing of users input and the ‫جة‬ computer generate genuine result based on the users ‫ين‬ input.  Digitally Represented Digitization: process involved in transforming an analog signal to digital signal. ‫ عملية تتضمن تحويل اإلشارة‬:‫الرقمنة‬ ‫التناظرية إلى إشارة رقمية‬. Components of a Multimedia System 1.

Capture devices / Input Devices - Keyboard, scanner, video camera. 2. Storage Devices - Hard disk, optical disk. 3. Communication Network - Modem, network card, cables 4. Computer System - CPU, RAM, Display card. 5. Display Devices - Monitor, Projector, Printer. Multimedia Computer Architecture  Digital Audio and Video Digital audio and video typically require specialized hardware and software for ‫صة‬ capture and playback. :‫مي‬ There are 3 aspects of the digital audio video operation: ‫و‬ 1. Capture-raw analog sources are digitized. 2. Storage-Files are stored and transmitted. 3. Playback-Playback based on hardware or software, digital to analog conversion.  Multimedia Software There are two classes of software that make up desktop software and ‫مج‬ multimedia products: :‫ددة‬ ‫هي‬ 1) Executables: executables are ‫ميع‬ completely self-contained executable ‫تبات‬ programs that provide for all functionality of a particular application. 2) Libraries: the libraries are often called dynamic link libraries.  Multimedia Application? Any computer application that contain or use Multimedia elements. ‫ائط‬.‫ًا‬ A multimedia application is more like a movie or a book. Content must be created and produced. Usually, interactive.  Examples of Multimedia Application ‫ش‬ World Wide Web ‫من‬ Hypermedia courseware ‫الت‬ Computer-based Training (CBT) ‫تل‬ ‫الع‬ Interactive TV ‫الو‬ Computer Games ‫أنظ‬ Virtual reality Multimedia Database systems  Delivering Multimedia :‫م‬ Multimedia can be delivered using: ‫سليم‬ 1- Optical disk (CD-based) ‫ة من‬ The most cost-effective method of delivery ‫وت‬ for multimedia materials. ‫ى‬ These devices are used to 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 compress before transfer  Web-based CD-based Limited in picture size and Can store high end low video resolution Multimedia elements Can be changes, damaged Can be permanently stored or deleted by irresponsible and not changeable individuals Information can be updated Information can be quickly easily and cheaper outdated  Reference Multimedia Technology & Applications, David Hillman,1997,First edition, Delmar Cengage Learning ,ISBN-13: 978- 0827384989 Education – GameMaker Help Centre (yoyogames.com) https://gamemaker.io/en/download https://gamemaker.io/en/tutorials https://www.youtube.com/playlist?list=PLwfY1MeupeNZ11cAzjyiDFwA y58mWNKL7 https://www.youtube.com/watch?v=fSXlELAB5jU Introduction to Multimedia
