Human Centric Computing(Comp 106)Assignment 2

PROPOSAL 21

• Our task is to design a new user interface for the Liverpool University Library catalogue system.

• The new design must take a direct Manipulation style of interface

• Using a metaphor from real life as it’s basis, that users can identify with. Allowing even the most inexperienced user navigate the catalogue

The Current Design

• The current design is very simple and fairly easy to navigate for anyone experienced with web page navigation.

• However many of it’s features overlap and some are fairly confusing.

The New Design

• The metaphor I have decided to use for the catalogue is the library it’s self.

• Although this sounds fairly complex my intention is to make use of the aspects of the real library that people are familiar with.

HELP

Searching

• There are two ways of finding a book

• The first is to click on either of the two book shelves and brows the various category’s

• The second is to click on the computer on the main interface screen and do a search for the book via author/subject/title etc.

Why Fact or Fiction Bookshelves?

• The current search engine seems to frequently confuses these two categorises of books

• As books never belong within both categories separating them completely will narrow the users search substantially. Allowing them to more easily find what they are looking for.

Browsing Via the bookshelves

• Clicking on a bookshelves will take the user to a second screen, like the first this uses the metaphor for a book shelve.

• This bookshelf will hold various sub-categories the user can choose from by clicking on a book under the heading.

• As the user clicks they with be taken to further bookshelves with more sub-categories

• Each click the search will be narrowed bringing them closer the the desired category of book.

The bookshelves operations for Fact are principally the same as fiction. Both these bookshelves objects/operations can be scaled to the individual needs on the subject and it’s subcategories.
