Interantivity In Multimedia Application
Introduction
In the age
of technology, computer is familiar to human being as a technology product
unlike past time, that computer is used only in a company, scientist,
programmer and other professions. In the past time, computer was only used by
people to do or complete their job with using the application software
installed in their computer, and the application software that can be used in
computer was very limited. But in nowadays, the modern age, there are many
computer application software were developed by programmer for different
profession and also for entertainment. The application software are classified
to many categories, one of them is multimedia application. The impressions of
people about multimedia are picture, image, video, animation, game and so on. These
are only a minor part of multimedia and some of them are not the product of
multimedia, but they need the help of multimedia to complete them, e.g. game. Thus,
the importance of multimedia are unquestionably especially in the area of computing.
It also plays a key role in variety profession such as business, tourism
industry, advertising and so on.
Multimedia
Multimedia
is the integration of multiple forms of media that includes text, graphics,
audio, video and others. Users can choose from a range of media elements to
convey massage that the users wanted to.
“Multimedia
can be defined as an integration of multiple media elements (audio, video,
graphics, text, animation, etc.) into one synergetic and symbiotic whole that
results in more benefits for the end user than any one of the media elements
can provide individually” (Reddi, 2003). It
means that with the use of combination of the elements of media, it may bring
an interesting, attractive and easier understanding to the massage that user
may want to express compare to use only one element of media.

Application
An
application, or application program, is a software program that runs on
computer and each program has a specific application for the user (techterms.com). Multimedia application is one of them.
Multimedia application came with the capabilities to capture, digitize,
compress, store, decompress and present information. The aim of multimedia
application is to provide a creative and effective way of producing, storing
and communicating informations(hubpages.com).
Nowadays,
there are many multimedia application provided for entertainment, education,
corporate presentation and much more. The application for entertainment which
have Window Media Player, Cyberlink PowerDVD, Media Player Classic and much
more. There are also have application for editing photos which are the famous
Adobe Photoshop, Adobe Flash and much more. There are many applications for
multimedia from free of charge until paid for license and some are expensive.

Interactivity
In Multimedia Application
Interactivity
bring means two-ways between human being and other party(human being or
computer software or others). People interact with other people by
communicating through language, movement, facial expression and so on. This
interaction could be set up is because people can understand the expression
that the other people would like to express through communicating with
language. But, the way of interactivity between human being and computer is
different from people interact with people.
According
to Rada Roy(1995), the “Human Computer
Interaction model might consists of 4
main component which is HUMAN, COMPUTER, TASK ENVIRONMENT and MACHINE
ENVIRONMENT. The communication between people and computers : one must
understand something about both and about the tasks which people perform with
computers. A general model of human, computer interface emphasizes the flow of
information and control at the human computer interface.” The interactivity
between people and computer refers to software which accepts and responds to
input from humans.
There are
three stages involve in interactivity which are Input, Process and Output. User
use input device to give instruction and data to the application software, then
the application process the command that the user had inputted. After process,
the application display the output through the output device according to the command
that user had inputted.
There are
many type of input devices for user input the instruction to the computer and
process with the application software.

There are
also many types of output devices for displaying the information, output and
other data that user had inputted.

Example of Output Devices
Nowadays, most of the multimedia applications
are interactive program. Interactive program bring means a program which need
interaction or input from the user in order to operate or process the command
and display the output or result to the user. Some famous examples of the
multimedia application which are interactive program are Adobe Photoshop, Adobe
Flash and other multimedia application.
Example of Adobe Photoshop
Example of Adobe Flash
Most of the people use multimedia application
such like Adobe Photoshop, main use of them is editing photo. If an original
picture is not attractive, not suitable for posting, not nice to look and other
reasons, people would like to edit it to become attractive, beautiful and perfect
for posting. The famous multimedia application which people use often is Adobe
Photoshop. Photoshop has been around for over twenty years, it’s certainly
become more powerful. With using Photoshop, there are interactivity between
user and application.
First of all, user will use mouse to point and
click to operate the application, Adobe Photoshop. The application will
operating, process and run the Photoshop. After the application open, there is
an interface shown up and the application is ready for user to edit the
picture. User click at the menu bar to open the document which is the picture
user wanted to edit. Most of the user will use the Crop Toll to crop the
picture which part he or she is needed by clicking the crop tool at the tool
bar. User click and drag inside the image to draw the area to crop the part of
the image he wishes to keep with using the mouse. The area of the part of image
wish to keep will be cut.
The image will be crop
Most of the people also used to be adding text
to the picture they want. With using the Text Tool, text will enabled to add on
to the picture. User can input any words he would like to add and add on the
text to any part of the picture. The size of the text can be added in with
large size or small size which is depending to user’s wish. The colors, font
styles, wraps and other patterns of the text can be also input according to the
user’s preferences. User selects the tool with using the mouse and type in the
text with using the keyboard. After the processing of the command user had
input, the Photoshop will display the result picture.

Reflection and Conclusion
After the research, we have learnt the
interactivity between multimedia application and user. User use the input device
giving command to the application and the application will processing and give
output as result to the user. The quality of the output is depended to the user’s
proficiency. Proficient user may input expertise instruction, data, or command
to the application, the application may processing with the accurate data and
the output or result display to the user will become more accurate and high
quality.
The result outcome from a proficient user and a
basic skill user are different in quality and the perfection of the output. A
basic skill user may not holding the efficient skills will unable to make a
high quality output because of the less interactivity between the user and the
application. With less interactivity with the application, the user may unable to
outcome the result which he expected to get.
In conclusion, learning, knowledge and skill
are necessary for the user of multimedia application. The quality of the result
may depend on how skillful and how proficient the user. Interactivity between
user and the multimedia application is necessary also for the user. It brings
many benefits to learning and knowledge to an user for future study and work.
