Interactivity in multimedia application

Introduction

The term "look and feel" is often used to refer to the specifics of a computer system's user interface. Using this metaphor, the "look" refers to its visual design, and the "feel" refers to its interactivity. Every action in your mind after understanding the user interface means you are communicating with the system. That is interactivity. Indirectly this can be regarded as an informal definition of interactivity.

In computer science, interactive refers to software which accepts and responds to input from humans—for example, data or commands. Interactive software includes most popular programs, such as word processors or spreadsheet applications. An essential feature of interactivity is that it is mutual: user and machine each take an active role. Most interactive computing systems are for some human purpose and interact with humans in human contexts.

User Interface Principles

 

A good man-machine interface specification compliance the way that users' thinking and action, and not depend on the device performance. An user interface which is unattractive and complex will make a good application become worse than before. Otherwise, a beautiful and intuitive perception interface can strengthen the functionality of the application and also can encourage users.

•The beauty of the overall

The beauty of the overall, is not simply refer to how beautiful the application interface, but rather whether the appearance and functionality of the application combination perfect. For example, to deal with the task applications usually simplifies the decorative UI elements and put it in the background, so that give the task itself an important position. Then the users can easily understand the aim and the feature of the application.

 

 

 

• Operation directly

When the user can operate the objects in the screen directly and no need to use other control to operate, they will be interested in the task itself more easier than before. And also more easier to understand the result of the operate. Multi-touch technology allows iOS users to experience the convenience of operation directly. By using touch screen, the user will have more kindly with the user interface and more sense of control. Because of the users do not need some other devices, like mouse.

In an iOS application, the following ways can allow users to experience the direct operations:

--- By rotating or moving device to affect the screen objects

--- By using touch screen to control the objects which in the screen

--- It seems that to see the result of the operating very soon

 

 

 

 

User Experience Guidelines.

• Consider the sequence

Top of the screen is the most likely to be noticed by the user's. User holding the device, usually has the following ways to interact:

--- Use their not used hands to hold, use the most used fingers to operate.

--- Use one hand to hold, and use its thumb to operate.

--- Between two hands, and use two thumbs to operate.

Put the most frequently used information on the top of the screen, there is most likely to be found. When users access the screen from top to bottom, showing the information should be from the general to the particular, from the high level to the low level.

• Make everything easy and obvious

You should try to let your application be understood more easier, because you are not sure whether the user want to spend time to research it. Straight to show the core functions by using the following ways:

--- Reduce the controls which need users to make choices

--- Rational use of standard controls and gestures, and pay attention to maintain consistency

--- Control labels need to be clear, so that the user can clearly know what they are doing

 

• Use the terminology that can be understood by users

When use the text to communicate with the users, try to use the terminology that can be understood by users. Especially, try to avoid to show some technical speech in the user interface. Because most people like to see the sentences which is simple and concise. These can make them feel comfortable. From the user's point of view to consider whether the words used by apt.

For example, Wifi network settings interface will use simple words to explain.
