What are requirement?
Requirement is a statement that list out all the NEED and SHOULD, a requirement should be list out all the NEED and SHOULD as clear, specific as possible. A requirement must know how to tell when they have been fulfilled. For example: when we download an object, it must state how much space that is object need and how long it need to download.
There are 2 types of requirement in software engineering, that is functional requirement and non-functional requirement. In functional requirement, it always shows what the system should do. For example when we write an article using software it will say that we should support a variety of formatting style by the paragraph, character and etc. In non-functional requirement is another kind of statement. Non-functional requirement show that what are the constraints on the system. For example with the same software write an article it will state that what must be able to run that target platform such as PC, MAC and etc or target platform must have at least 2 GB RAM.

On the other hand, requirement has several types in interaction design. It is functional requirement, date requirement, environmental requirement, user characteristic, and usability goal and user experience goals.
Functional requirement:
Functional requirement is all about to state what the product should do
Data requirement:
Data requirement:
In data requirement is to state the type, size, accuracy, value and other necessary information of the required data. For example when transferring a file to another place it must state that it still need how many mb or gb more to transfer the file.
Environmental requirement:
Environmental requirement:
Environmental requirement is about the circumstances in which the interactive product will be operated.
User characteristic
User characteristic is to state or show the intended user group or open few profile for different type of users (persona) for the target users. For example: the user’s skills and ability, educational and etc.
Usability goals and user experience goals
Usability goals are the safety, efficiency, effectiveness, utility and etc. User experience goals are all about the fun, the excitement and the enjoyable.
