Multimedia • Presentation of a computer application (usually interactive) • Incorporating media elements such as text, graphics, video, animation and sound on a computer. Multimedia Systems • encompass the computer and software systems that are used in multimedia environments • Interactive control Definition of Multimedia Multimedia is any combination of text, art, sound, animation, and video delivered to user by computer, or other electronic or digitally manipulated means. Introduction to Multimedia • Multimedia becomes interactive multimedia when a user is given the option of controlling the elements. • Interactive multimedia is called hypermedia when a user is provided a structure of linked elements for navigation. Introduction to Multimedia • A multimedia project development requires creative, technical, organizational, and business skills. • Multimedia developers develop multimedia projects. Introduction to Multimedia • Multimedia projects can be linear or nonlinear. • Projects that are not interactive are called linear. • Projects where users are given navigational control are called non-linear and user- interactive. 4 Characteristics of Multimedia Product • Information present on a computer. Without this feature Polymedia or Mixed Media • Links. Without this feature Book • Navigation tools (icon, button, hot spot) • Interactive presentation. Without this feature TV Newspaper were the first mass communication medium to employ Multimedia -- they used mostly text and graphics sent his first Gugliemo wireless radio Marconi transmission at Pontecchio, Italy. detected radio waves beamed across the Atlantic • Television was the new media for the 20th century. • It brings the video and has since changed the world of mass communications.

Virtual reality was invented with both head-mounted display and dataglove A device that transmits data from an array of movement and position sensors. • 1990 – Adobe released Photoshop, a photo editing and graphics design application • 1992 – the first children’s interactive book title, “Just Grandma and Me” was launched • 1994 - Jim Clark and Marc Andreesen: Netscape • 1995 - JAVA for platform-independent application development. • 1996 - Microsoft, Internet Explorer. NOW!! Why Apply Multimedia Technology • Ease of use • Intuitive Interface • Immersive Experience • Self-Paced Interaction and Better Retention • Better Understanding of the Content • Cost Effectiveness • More Fun = Greater Efficiency Applications of Multimedia • Business - Business applications for multimedia include presentations training, marketing, advertising, product demos, databases, catalogues, instant messaging, and networked communication. • Schools - Educational software can be developed to enrich the learning process. Applications of Multimedia • Home - Most multimedia projects reach the homes via television sets or monitors with built-in user inputs. • Public places - Multimedia will become available at stand-alone terminals or kiosks to provide information and help. Summary • Multimedia is a combination of text, graphic art, sound, animation, and video. • Multimedia projects can be linear or nonlinear. • Multimedia projects are often stored on CD-ROM or DVDs.
