Introduction

Part 1 To begin the process of designing a web site you should create a paper prototype of five linked web pages. Paper prototyping is a variation of usability testing where users perform realistic tasks by interacting with a paper version instead of a computer. With this we can obtain feedback from the user and then it be dealt with before creating a web page. The think-aloud technique is concerned with the behaviour of an individual when performing a task. We interviewed one user because we felt that if more users were to do the prototype, then information will be discussed. We told the participants at any time they could leave if they felt uncomfortable in the situation. We use the feedback from the think-aloud technique to improve our design in a variety of ways. When testing the usability of our prototype with the user, they mention that there was no drop down menu on the checkout section for some of the field such as card type. The user found this very inconvenient due to the fact that they had to fill it out by them self and that most sites they visit has one. ...read more.

(466 words) Part 2 Discuss briefly the advantages of paper-based prototyping, with particular reference to your own prototype (not to exceed 500 words). The Advantages of Paper - Based Prototyping Paper Prototyping is considered by many to be an easy to use and efficient tool to plot out an interface seen by the user. It has a number of advantages which we experienced while making our prototype as well. Some of these are listed below: It is probably the simplest of all Prototyping Techniques Paper Prototyping can be considered as the simplest of all prototyping techniques because we can create an entire interface using nothing more than office stationery. Any corrections or changes that need to be made after initial testing can be made effortlessly. It can be used to exactly reproduce the image of an interface which is present in the developer's mind. Since there is no coding required, it is also a speedy way to create an initial interface. Our prototype took us just about a week to complete and any of the finer points that needed to be changed were done by just replacing the post - it notes, etc. ...read more.

Conclusion

It also requires creativity, not only from the people involved in making the prototype but from the users as well. It is a great way to discover how people would go about making interfaces and expressing themselves. (529 words) Part 3 Implement the five pages from your paper prototype using Dreamweaver. The pages must demonstrate that you have considered user-centred design issues. As a minimum your pages should include images, text, and hyperlinks. You may include additional features, e.g. rollover images and popup menus, provided that they function correctly. You may include links to external web pages if relevant. All hyperlinks between the pages must be relative, not absolute, so that the pages will function correctly when copied to another location. * Please insert the provided CD * On Ms Windows go to "My Computer" * Select and double-click your CD-Rom drive * Open the file "index.htm" * The site should open in your preferred browser window. Enjoy. Part 4 Finally you must evaluate your web pages, using any one (and only one) of the following evaluation techniques: Cognitive Walkthrough for StudentDVDs.com (549 words) ?? ?? ?? ??
