Tutorial 1 (Week2, Text Book Pg.15)

1) Briefly discuss the history and future of multimedia. How might multimedia be used to improve the lives of its users? How might it influence uses in negative ways? What might be its shortcomings?

What is Multimedia?

Multimedia, In common usage, refers to an electronically delivered combination of media including video, still images, audio, text in such a way that can be accessed interactively. Much of the content on the web today falls within this definition as understood by millions. Some computers which were marketed in the 1990s were called "multimedia" computers because they incorporated a CD-ROM drive, which allowed for the delivery of several hundred megabytes of video, picture, and audio data. That era saw also a boost in the production of educational multimedia application CD-ROMs.

History of the term Multimedia

The term multimedia was coined by singer and artist Bob Goldstein to promote the July 1966 opening of his "LightWorks at L'Oursin" show at Southampton, Long Island. Goldstein was perhaps aware of a British artist named Dick Higgins, who had two years previously discussed a new approach to art-making he called "intermedia". 

On August 10, 1966, Richard Albarino of Variety borrowed the terminology, reporting: “Brainchild of songscribe-comic Bob (‘Washington Square’) Goldstein, the ‘Lightworks’ is the latest multi-media music-cum-visuals to debut as discothèque fare. Two years later, in 1968, the term "multimedia" was re-appropriated to describe the work of a political consultant, David Sawyer, the husband of Iris Sawyer—one of Goldstein’s producers at L’Oursin.

In the intervening forty years, the word has taken on different meanings. In the late 1970s, the term referred to presentations consisting of multi-projector slide shows timed to an audio track. However, by the 1990s 'multimedia' took on its current meaning.
In the 1993 first edition of McGraw-Hill’s Multimedia: Making It Work, Tay Vaughan declared “Multimedia is any combination of text, graphic art, sound, animation, and video that is delivered by computer. When you allow the user – the viewer of the project – to control what and when these elements are delivered, it is interactive multimedia. When you provide a structure of linked elements through which the user can navigate, interactive multimedia becomes hypermedia.

The German language society, Gesellschaft für deutsche Sprache, decided to recognize the word's significance and ubiquitousness in the 1990s by awarding it the title of 'Word of the Year' in 1995. The institute summed up its rationale by stating "[Multimedia] has become a central word in the wonderful new media world.

History of Multimedia


Printing Press

The printing press was invented in the Holy Roman Empire by the German Johannes Gutenberg around 1440, based on existing screw presses. Gutenberg, a goldsmith by profession, developed a complete printing system, which perfected the printing process through all of its stages by adapting existing technologies to the printing purposes, as well as making ground breaking inventions of his own.

Gazettes Newspapers

The newspaper in its modern form is usually regarded as beginning in 1566, when the government of Venice, Italy, issued written news-sheets and exhibited them in the streets. Anyone was allowed to read them on payment of a small coin called Gazetta. Onthis account the news-sheets were called gazettes.
In 1822, Charles Babbage proposed the use of such a machine in a paper to the Royal Astronomical Society on 14 June entitled" Note on the application of machinery to the computation of astronomical and mathematical tables". This machine used the decimal number system and was powered by cranking a handle.


Analytical Engine

The Analytical Engine was a proposed mechanical general-purpose computer designed by English mathematician Charles Babbage. It was first described in 1837 as the successor to Babbages Difference Engine, a design for a mechanical computer.


 
In 1879, Thomas Edison granted the patent of phonographs.


Adding Machine

In 1886, Burroughs First commercially successful adding machine.

The first primitive radio transmitters (called Hertzian oscillators) were built by German physicist Heinrich Hertz in 1887 during his pioneering investigations of radio waves. These generated radio waves by a high voltage spark between two conductors.


Tabulating Machine

The tabulating machine was an electrical device designed to assist in summarizing information and, later, accounting. Invented by Herman Hollerith, the machine was developed to help process data for the 1890 U.S. Census. It spawned a larger class of devices known as unit record equipment and the data processing industry.


Nickel-in-the-slot phonograph

 In 1890, Louis Glass and William S.Arnold invented the nickel-in-the-slot phonograph, the first of which was an Edison Class M Electric Phonograph retrofitted with a device patented under the name of Coin Actuated Attachment for Phonograph. The music was heard via one of four listening tubes. Early designs, upon receiving a coin, unlocked the mechanism, allowing the listener to turn a crank which simultaneously wound the spring motor and placed the reproducers stylus in the starting groove.


Mickey in the Steamboat Willie

Steamboat Willie is a 1928 American animated short film directed by Walt Disney and Ub Iwerks. It was produced in black-and-white by The Walt Disney Studio and released by Celebrity Productions. The cartoon is considered the debut of Mickey Mouse, and his girlfriend Minnie.


Magnetic Tape

Magnetic tape was invented for recording sound by Fritz Pfleumer in 1928 in Germany, based on the invention ofmagnetic wire recording by Valdemar Poulsen in 1928. Pfleumers invention used a ferric oxide (Fe2O3) powder coating on a long strip of paper. This invention was further developed by the German electronics company AEG, which manufactured the recording machines and BASF.

Atanasoff-Berry Competer

The Atanasoff–Berry Computer (ABC) was the first electronic digital computing device. Conceived in1937, the machine was not programmable, being designed only to solve systems of linear equations.



Zuse - Z3

1943:Zuse – Z3: First machine to work on a binary system rather than decimal system.


The first transistor

1948: Shockley, Bardeen and Brattain develop the transistor. More reliable and cheaper to run the vacuum tube.

IBM 701

IBM 701: First electronic stored computer that use vacuum tubes, Ram, punch cards and was the size of a piano, was announced to the public on April 29, 1952

Atari 1972

In 1972 the first commercial video game was released by The Atari inc.


SONY Betamax VCR

SONY Betamax VCR with a one hour, ½ inch video cassette tape.1975.

Future of Multimedia

1) Graphic imaging technology


There is a concept of future technology - Graphic imaging technology. With it users can effortlessly and instantly inquire everyday info such as calendar, stock market, maps, ID card, weather report and so on. It also allows high definition video playback to make your video chat and long-range cooperation better with dynamic adjustment of the screen size. Amassing a vast collection of songs, users can enjoy high-fidelity sound quality on the go. Providing a flexible user interface, the portable device ensures an immersive game experience so the avid gamers could have an unprecedented game life.







2) Virtual reality - It uses multimedia content. Applications and delivery platforms of multimedia are virtually limitless.


3) Flexy Multimedia Device 


How might it influence uses in negative ways

Nowadays, children use a variety of multimedia learning programs, which either seek to teach or reinforce basic skills in math, language, reading, and other subjects. Other software allows children to draw pictures or create visual works of art and self-expression. Communication with others is growing as an application of computers by children, particularly as more homes and schools gain access to the Internet. As computers continue to become more powerful, increasing numbers of children are using computers to create multimedia presentations and even web sites that include pictures, text, audio, and even video.

In addition, for e-learning, the learners self-guide through the training. This is 
problematic for those not used to being a self-directed learner, are uncomfortable by the lack of 
an instructor or are not comfortable relying on objectives. These variations on learner’s 
preferences may result in a hesitancy and reluctance to learn. Those whose learning style 
requires more structure and guidance may become frustrated. Some less-experienced or less 
well-disciplined learners may also make poor decisions about how much information they need, 
resulting in information overload.

Shortcomings of multimedia

There are several shortcomings which are:

1) Information overloads. Because it is so easy to use, it can contain too much information at once.
2) It takes time to compile. Even though it is flexible, it takes time to put the original draft together.
3) It can be expensive to develop. Multimedia makes use of a wide range of resources, which can cost large amount of money.
4) Too much makes it unpractical. Large files like video and audio has an effect of the time it takes for the presentation to load. Adding too much can mean that you have to use larger computer to store the files.
5) In case you want to upload it onto the internet, there are a few factors to consider, for example, network bandwidth. 



3) Multimedia is shifting from being localized (contained on a CD-ROM) to being distributed (available on the World Wide Web). What are some of the implications of this? Who will have access to the presentation? How will you keep it secure? How will you distribute it?

What are some of the implications of this?


It implicates that users are able to access the multimedia from different locations and reduce the distribution of multimedia cost. It allows people to move easily from one Web page to related information elsewhere on the same page, on the same site or one a different site half-way around the world. Besides that, it allows people to Localize and scope of media mentioned above concerned geographical aspects. This is also true for thematic aspects. There are today millions of communities specialized on specific themes (languages, hobby, nature,…). While there are thematic radio, newspaper, TV, and magazines, their diffusion is geographically limited, while these communities are spread over the Web. The Web, by connecting people, enables those with shared interests to exchange their resources independently of their respective locations.


Who will have access to the presentation?

Only the authorized and related users have the right to access to the presentation. 


How will you keep it secure?


When keeping files in internet, always use a difficult to guess password on all websites. Avoid using a single combination of username/password for all websites. Secondly, use encryption software to protect sensitive data. Keep all your sensitive data in one main folder and use a software like TrueCrypt to create an encrypted volume. With encrypted volume to store all your sensitive data, even if you lose your laptop, your data will be safe. Thirdly, Use the HTTPS versions of sites. This simple fix will help you keep the data you send back and forward between your computer and websites like social networks private. 

How will you distribute it?


I will distribute the files through email, I will make sure that I send to the correct persons. Besides that, password is required to open the files. Also, I will upload the files to a online storage and put a strong password to protect it.
