Paper Prototyping

Paper prototyping is a method of user-centered design ( User Centered Design). It is tested by means of drawn or printed GUI components, the behavior of any renewed or to be adapted software. Paper Prototyping can be used in a process 13407 DIN EN ISO.

The paper prototyping can be divided into two categories:

1 Lo-Fi Prototyping (low -fidelity prototyping) Low Fidelity Prototyping is English and means low similarity. " This test method gives you the possibility to examine ideas and processes early. Advantages Lo-Fi Prototyping:

  • No programming required
  • Testing in the design phase
  • Quick and easy changes
  • Subjects express above average number of proposals

Disadvantages Low Fidelity Prototyping:

  • Interaction processes must already be clearly defined in the design phase
  • Many rough drafts
  • No functionality of the prototype, therefore limited error detection
  • Prototype can only be used for lo-fi prototyping
  • Not all ideas and processes are technically feasible

2 Hi- Fi Prototyping ( High-fidelity prototyping)

Expiration

If there is already a GUI design, which is to be tested, this is printed. Alternatively, a first rough sketch of the application by a member of the development team is created. This is based on the previously specified requirements. All GUI components that can be turned on and be hidden, printed or drawn separately.

The test conductor shall be composed of one to two users and gives them a task that should solve it with the new " software ". Starting from an initial mask describes the user now spontaneously what he wants to do and what he expected to see. The test administrator assumes the role of the software, by performing mask change or components fades by hang on the mask and removed from it.

Once the test administrator to identify new requirements, these are noted to respond later in the requirement specification.
