PROTOTYPING

It can also mean a re-creation of a tool or software especially in the field of computer-designed tailored to its original form ... ....

Prototyping made to:- Create a new variant of the device or software that already exist with the design or - change the appearance slightly.- Increases in utility tool designed.
- More reduce the cost or price of the tool that created a prototype.
UCD is about the design of interactive technologies for
meet the needs of users.

Stages in UCD:
- Designing a tool that more needed by users.
- Designing a prototype as an another alternative for the user.
- Strategic Planning.
- Evaluate each new design and existing.

Method of Making Non-Computer Prototyping
Non-Computer Methods (Manual) Goal
Want to declare a new design ideas by using simple and inexpensive technique. and fast opinions of the system.
Design Description
Can be a textual description of a system design.
- Weaknesses are the lack of resemblance with the existing system
- The results are not predictable amount of production.
- Unable to done quickly.

Sketches, mock-ups
- Paper-Based to "define" interface.
- Good for expressing opinions.
- Focused on people with high-level design.
- Not too good to describe the plot and details.
- Cheap and fast feedback is very helpful.

Story boarding
Pencil and simulation of a note or a walk through of the ability and the display system.
- Use sequence diagrams / images.
- Demonstrate key snap shots.
- Cheap and easy.

Scenario
Hypothesis or designer's imagination.
- Usually includes several people, events, environments and situations.
- Provide operational context.
- Sometimes in a narrative format, but also can be a sketch or even a video.

Utilities Scenario
- Involving and engaging.
- Allows designers to view the problem from the view of others.
- Facilitate feedback and opinions.
- Can be very creative and futuristic.
Other Techniques

Tutorials and Manual
- Maybe write it more useful than stored in the head.
- Forcing designers to make decisions with the firm.
- Write / put it on paper is much more valuable.

Computer-Based
Computer Methods
Goal
- Imitate more system.and ability to design with the new concept faster.
- Can be centered more details
- To produce products more quickly
.
Example sketch:
- The sketch is very important for low-fidelity prototyping.
- Do not be afraid of drawing ability.
- Presenting "the look" dirty and fast from the interface, concept design, etc..
Examples of "wizard-of-oz":
- User think they interact with computers, but developers better results than the system response.
- Usually done in the initial design to understand what expected by the user.
6. Mid-fidelity prototyping (prototype with a medium level of accuracy)
- Form schematic.
- Navigation and the simulated functions are usually based on what appears on the screen or the simulation screen.
- Examples of tools used: power point, illustrator, etc..
7. High-fidelity prototyping (prototype to the level of precision
high)
- Hi-fi prototype as the final system.
- Using the same materials as the final product.
Tools commonly used: Macromedia Director, Visual Basic,
Flash, Illustrator.

Prototyping Tools
1. Draw / Paint program, Photoshop, Coreldraw
- Draw every screen, good to see.
- Prototype horizontal, thin.
- Adobe Photoshop.
2. Scripted Simulations / Slide Show, for example: PowerPoint, Hyper Card,
Macromedia Director, HTML.
- Put the view like a storyboard with the (animated) changes
among others.
- Can provide a very specific user record.
- Called chauffeured prototyping.
- Macromedia Director.
3. Interface Builders, for example: Visual Basic, Delphi, UIMX.
- Tools to display the window, control, and others from
interface.
• A good feature
- Easy to develop and modify the screen.
- Support the kind of interface is developed.
- Supports multiple device Input / Output.
- Easy to modify and connect the screen.
- Allows to call external procedures and programs.
- Allows importing text, graphics, other media.
- Easy to learn and use.
- Support the good of vendor.m
