The Definition of "Media" (on-line definition by Webopedia http://www.webopedia.com/)
(1) Objects on which data can be stored. These include hard disks, floppy disks, CD-ROMs, and tapes. (papers are also one kind of media)
(2) In computer networks, media refers to the cables linking workstations together. There are many different types of transmission media, the most popular being twisted-pair wire (normal electrical wire), coaxial cable (the type of cable used for cable television), and fiber optic cable (cables made out of glass).
(3) The form and technology used to communicate information. Multimedia presentations, for example, combine sound, pictures, and videos, all of which are different types of media.
Computers as Media. "The computer is both the tool of multimedia and its medium. ....Multimedia is interaction with multiple forms of media supported by the computer." (Cartwright and Peterson, p. 1, 1999, Multimedia Cartography).
GIS as Media. Sui, D.Z., 1999. GIS as media? Or how media theories can help us understand GIS and society. Book chapter for GIS and Society: An international perspective, eds. E. Sheppard and R. McMaster
Maps as Media. Maps could be used to store and communicate geographic information. "...providing a map that is not just a picture of geographic reality, but also a search engine which, as well as giving access to geographical data and a means of data selection and display... The geographically linked ""things"" are a conglomerate of items, systems, processes and conventions." (Cartwright and Peterson, p. 4, 1999, Multimedia Cartography).
WWW as Media. The Web could be used to store and communicate information (multimedia presentation).
The Definition of "Multimedia" (on-line definition by Webopedia http://www.webopedia.com/)
The use of computers to present text, graphics, video, animation, and sound in an integrated way. Long touted as the future revolution in computing, multimedia applications were, until the mid-90s, uncommon due to the expensive hardware required. With increases in performance and decreases in price, however, multimedia is now commonplace. Nearly all PCs are capable of displaying video, though the resolution available depends on the power of the computer's video adapter and CPU.
Because of the storage demands of multimedia applications, the most effective media are CD-ROMs.
Currently, the Web could become the most effective media. or TV Cables?
"Multimedia as an information interface. Multimedia is a new form of visual and aural presentation and expression." (Cartwright and Peterson, p. 5, 1999, Multimedia Cartography).
Could we say that "GIS is in the end just a set of tools for producing spatial information whereas multimedia cartography is a set of tools for presenting geographic information" ? (Please compare this one to the statement in p. 6 of the Cartwright book: "Computer graphics is in the end just a set of technical tools for producing imagery whereas multimedia is a set of tools for using imagery.")
The Definition of "Hypermedia" (on-line definition by Webopedia http://www.webopedia.com/)
An extension to hypertext that supports linking graphics, sound, and video elements in addition to text elements. The World Wide Web is a partial hypermedia system since is supports graphical hyperlinks and links to sound and video files. New hypermedia systems under development will allow objects in computer videos to be hyper linked.
"It is a communication medium created by the convergence of computer and video technologies and it describes the whole spectrum of new interactive media spanning telecommunications, High Definition Television (HDTV), interactive cable television, videogames, and multimedia. .... Hyper documents could also include things like tastes, odors and tactile sensations". (Cartwright and Peterson, 1999, p. 20)
- Hypertext is a text which contains links to other texts. The term was invented by Ted Nelson around 1965. Hypertext is therefore usually non-linear (comparing to books and movies).
- Linear media (books, movies) vs. Non-linear media (hypertext) -- Which one is better? (Video tapes vs. DVD)
Hypermaps: Laurini and Millert-Taffort (1990) first introduced the term "hypermap". "Hypermap is an interactive, digitized multimedia map that allows users to zoom and find locations using a hyperlinked gazetteer (Gotton and Oliver, 1994).

The History of Multimedia Applications
Who introduced the concept of multimedia or hypermedia?
Bush, Vannevar (1945).
As We May Think. (Required reading!)
The Atlantic Monthly, vol. July: 101-108.
(Source: http://www.theatlantic.com/unbound/flashbks/computer/bushf.htm )
He was the Director of the Office of Scientific Research and Development (OSRD).
"Bush proposed a system, "MEMEX", a multi-dimensional diary with links to all connected things... His writings foreshadowed both the Personal Computer (PC) and the World Wide Web." (p. 13, Cartwright and Peterson, 1999).

The MIT Media Lab http://www.media.mit.edu/
"The outline of the Media Laboratory was formed in 1980 by Professor Nicholas Negroponte and former MIT President Jerome Wiesner, growing out of the work of MIT's Architecture Machine Group, and building on the seminal work of faculty members in a range of other disciplines, from cognition and learning to electronic music and holography. It officially opened its doors for business in the Wiesner Building, designed by I.M. Pei, in 1985. In its first decade, much of the Laboratory's activity centered around abstracting electronic content from its traditional physical representations, helping create now-familiar areas such as digital video and multimedia. The success of this agenda is now leading to a growing focus on how bits meet atoms: how electronic information overlaps with the everyday physical world. The Laboratory pioneered collaboration between academia and industry, and provides a unique environment to explore basic research and applications, without regard to traditional divisions among disciplines. Currently the Laboratory has approximately 170 sponsors. Information on sponsorship is available from Communications and Sponsor Relations (CASR).
The MIT Media Laboratory provides a unique environment for exploring basic research and applications at the intersection of computation and the arts. Areas of research include: software agents; machine understanding; how children learn; human and machine vision; audition; speech interfaces; wearable computers; affective computing (a new branch of computing that relates to, arises from, or deliberately influences emotions); advanced interface design; tangible media, object-oriented video; interactive cinema; work in various forms of digital expression, from text, to graphics, to sound; and new approaches to spatial imaging, nanomedia, and nano-scale sensing. "
Digital Life (DL) addresses the interconnection between bits, people, and things in an online world.
Digital Nations (DN) aims to address major social challenges (improving education, enhancing health care, supporting community development) through the innovative design and use of new technologies.
The News in the Future research consortium provides a forum for the MIT Media Laboratory and member companies to explore and exploit technologies that will improve the collection and dissemination of news.
Things That Think (TTT) explores ways of moving computation beyond conventional sites, such as PCs or laptops, and adding intelligence to objects that are first and foremost something else.
Spin-off company: Http://oblong.com
Andrew Lippman and his group at the MIT Architecture Machine Group (now part of the Media Lab) developed what is probably the first true hypermedia system, in 1978. The Aspen Movie Map was a surrogate travel application that allowed the user to enjoy a simulated ride through the city of Aspen.
The system used a set of videodisks containing photographs of all the streets of Aspen, Colorado. Recording was done by means of four cameras, each pointing in a different direction, and mounted on a truck. Photo's were taken every 3 meters. The user could always continue straight ahead, back up, move left or right. Each photo was linked to the other relevant photos for supporting these movements. In theory the system could display 30 images per second, simulating a speed of 200 mph (330 km/h). The system was artificially slowed down to at most 10 images per second, or 68 mph (110 km/h).
To make the demo more lively, the user could stop in front of some of the major buildings of Aspen and walk inside. Many buildings had also been filmed inside for the videodisk.
The system used two screens, a vertical one for the video and a horizontal one that showed the street map of Aspen. The user could point to a spot on the map and jump directly to it instead of finding her way through the city.

Three Attractive Keywords:
"People want to go into the map, both spatially and conceptually. ... Interaction is the key to knowledge formation" (Cartwright and Peterson, p. 2, 1999, Multimedia Cartography).
People like to see dynamic pictures or animations rather than static display. Dynamic display help people to "visualize" the change of spatial phenomena or "represent" 3D/4D surfaces.
"People seems to learn things more quickly when the learning process is fun. .... Multimedia Cartography can contribute to the joy of this discovery." (Cartwright and Peterson, p. 32, 1999).

Three Types of Media Functions: (Doris Dransch, from Cartwright and Peterson (edited), 1999, p.41)
1. To fulfill in the perception of information.
Avoiding information overload
Emphasizing important information
2. To fulfill in the knowledge generation.
Setting in context
3. To fulfill according to the purpose of communication.
Decision support function
A Paradigm shift: "Revolution" or "Evolution"?
A medium is the carrier of information? or
The Medium is the Message (McLuhan, 1967)
Example: Stroop Effect (Stroop, 1935)
Please tell us what the color is in the text?
Yellow Red Green
Literate people are visually incompetent because they have been so conditioned by the recognition of printed text. (Peterson, 1995).
The only acceptable way of approaching the new medium is by emulating the old -- through the rea-view mirror (McLuhan, 1967).
