Multimedia Computing Lawrence Goetz What is multimedia? Media=Way of Transmition There are multiple ways to display information using different medias, hence the name Multimedia. Any combination of text, graphics, sounds, etc. that is viewed to you on a computer. Basically a mixture of medias. When a user can choose the media content, then you have interactive multimedia. When the user can navigate (such as topic to topic), then you have hypermedia. Social Media Social Networking. Chatting, interacting, posting material. Facebook/Twitter Blogging. Generally oneway, the user posts information for others to see. A web log (blog) like a diary. Microblogging - limited to certain content, such as images or video. Wiki. People can collaborate on a topic and edit pages related to the topic (or post a new topic). Content Sharing. Such as sharing video. Social bookmarking. People rate and share website link Content Producers Consumers are the Producers. Social medial allows people to easily create and post content for others to view. Such as YouTube or Instagram Broadcast – For general audience Narrowcasting – For a specific targeted audience Old vs New Media Old: Physical media (analog). Record, tape, paper, etc. New: Digital. Electronic. Digital media is sampled (measurement of the physical properties) and digitized to electronic form. Modular. Adjust values of the various parts of the project at any time (generally) during production. Automation lets you easily create content. You can use various formats for your content (some are more universal than others). Such as JPG for images. History Of Multimedia 70’s Pong first commercial multimedia product Atari: Home System, Cartridges. 80's Nintendo VR, head-mounted display, data glove. i386 gave PCs power to use multimedia well. People could burn their own CDs History Continued 90's Adobe Photoshop WWW - broswer, mosaic. HTML MPC - Multimedia Personal Computer standard. DVDs USB Devices History Continued Current Multimedia Devices Smartphones Tablet Computers Bluray Discs 3D TVs eBooks Cloud Storage Building Multimedia Convergence of technology - Devices will merge. Education & Edutainment Bandwidth – How fast the content will take to load. Storyboarding - visual layout or map of your project. Multimedia makes for a good interface to an application. Intuitive Interface. Make sure icons are meaningful. Evolution of the interface The Interface is how you interact with the software running on the computer. Hardware and Software have changed to allow the Interface to evolve. Command Line Text Menus by keys Text by mouse. Drop down menus. Icons and graphics (GUI, graphical User Interface. Pronounced ‘gooey’) Sound and Sight Multimedia Styles Immersive Experience - software application takes over the entire computer screen. Applications across platforms should have the same look and feel. Also similar programs have the same general concepts. Index: visually and textually Graphical User Interface and Metaphors Hot Spots & Importance Styles Continued Make careful use of multimedia in your application. Have the right blend of multimedia. Linear vs. nonlinear (interactive) media Scripting or storyboarding helps you see the choices a user can make in your application. Authoring tools allow you to combine your media files into a navigational project with minimal programming. Multimedia Uses Business uses for multimedia • Computer Based Training - study at your own pace, various forms of media, cheaper, safer, more fun. • Marketing (Catalogs) • Video conferencing Schools -Simulations of hazardous topics. Like chemistry where chemicals can explode. Look up databases of various topics, like encyclopedias Home - Video games , Interactive TV Public Places - Information Kiosks Multimedia Tools Sound Image Video - Movie clips, DVDs Interleaving - synchronizing the audio with the video. QuickTime - Can mix various forms of data together. Such as titles, multi track files, etc. You can add various features, like 3D, etc, to your multimedia files. It has a Media Abstraction Layer that explains to the computer how to access the media elements contained inside of it. AVI - not as flexible as QuickTime. Compressing Movies will be covered when we get to video later on in the term. Screen Capture Tools Continued File Conversions Word Processors - Edit multimedia documents Presentation Packages - produce multimedia shows consisting of slides, audio clips, animations, movies, etc. Powerpoint is one such package. Hypermedia Programs - go beyond linear slideshows and allow the user to navigate through them. We will use Powerpoint to make an interactive Kiosk. OCR (Optical Character Recognition)- turns printed text to electronic text. Tools Continued • • • • • Paint & Drawing Tools 3D Modeling software - Sketchup from Google Photoshop (bitmaps) Fireworks (vectors or bitmaps) Image editors typically allow you to import a photo from a camera, scanner, etc. They also allow you to have plugins to enhance the features. Such as a special effects plugin. Tools Continued • Authoring Systems - allow you to evaluate input from the user, branch in your program according, and allow for a wider range of user interaction are called authoring systems. They typically have a flow chart showing the organization of the program. • Web Page Creation - Dreamweaver, Front Page, and other programs allow you to create web pages by using WYSIWYG (what you see is what you get) Computer Parts Memory RAM More is needed for media production, because the programs that create the content demand more power (generally) than those that view the content. If you run out of memory, the system will swap memory to the hard drive and this slows things down conciderably. Flash Memory Hard Drive DVDs (Digital Versatile Disc) can hold GBs of data. CD-R/W Blu-ray Input Devices Keyboards Mice/Trackballs Touchscreens Scanners Video Capture Cards OCR (Optical Character Recognition) helps get printed text into electronic text. Microphone Voice Recognition Digital Camera Output Devices Speakers Monitor Printers What others can you think of?
