QNo.9 when observation is useful and how to observe? (5 Marks)
Answer:-
Observing is useful at any time during product development. Early in design, observation helps designers understand users’ needs.
How to observe
The same basic data-collection tools are used for laboratory and field studies (i.e., direct observation, taking notes, collecting video, etc.) but the way in which they are used is different. In the laboratory the emphasis is on the details of what individuals do, while in the field the context is important and the focus is on how people interact with each other, the technology, and their environment. Furthermore, the equipment in the laboratory is usually set up in advance and is relatively static whereas in the field it usually must be moved around. In this section we discuss how to observe, and then examine the practicalities and compare data-collection tools.

QNo.13 Application software implemented in file system model?
Answer:-
Software implemented in the file system model: Our software is already designed and built that way, and users are used to it neither of these arguments is valid. The first one is irrelevant because new programs written with a unified file model can freely coexist with the older implementation model applications. The underlying file system doesn’t change at all. In much the same way that toolbars quickly invaded the interfaces of most applications in the last few years, the unified file model could also be implemented with similar success and user acclaim.
The second argument is more insidious, because its proponents place the user community in front of them like a shield. What’s more, if you ask users themselves, they will reject the new solution because they abhor change, particularly when that change affects something they have already worked hard to master — like the file system. However, users are not always the best predictors of design successes, especially when the designs are different from anything they’ve already experienced,

Answer:-
Understanding what activities are involved in interaction design is the first step to being able to do it, but it is also important to consider how the activities are related to one another so that the full development process can be seen. The term lifecycle model is used to represent a model that captures a set of activities and how they are related.
SDLC stands for Software Development Life Cycle. A Software Development Life Cycle is essentially a series of steps, or phases, that provide a model for the development and lifecycle management of an application or piece of software.

QNo.42 Discuss the model problems of multiple undo.
Answer:-
The problems with multiple undo are not due to its behavior as much as they are due to its manifest model. Most undo facilities are constructed in an unrelentingly function-centric manner. They remember what the user does function-by-function and separate the user’s actions by individual function. In the time-honored way of creating manifest models that follow implementation models, undo systems tend to model code and data structures instead of user goals. Each click of the Undo button reverses precisely one function-sized bite of behavior. Reversing on a function-by-function basis is a very appropriate mental model for solving most simple problems caused by the user making an erroneous entry. Users sense it right away and fix it right away, usually within a two- or three-function
Limit.
For Example
The Paint program in Windows 95 had a fixed, three-action undo limit. However, when the problem grows more convoluted, the incremental, multiple undo models don’t scale up very well.

It is no use planning to use experts to review an interface if none are available. Similarly, running usability tests requires expertise.

Even after we’ve used a Web site extensively, unless it’s a very small site we tend to have very little sense of how big it is (50 pages? 1,000? 17,000?). For all we know, there could be huge corners we’ve never explored. Compare this to a magazine, a museum, or a department store, where you always have at least a rough sense of the seen/unseen ratio. The practical result is that it’s very hard to know whether you’ve seen everything of interest in a site, which means it’s hard to know when to stop looking.

QNo.50 Explain the following planes of Conceptual Framework for developing an interactive product.
The Structure Plane
The Scope Plane

The Strategy Plane
Answer:-
The Structure Plane
The skeleton is a concrete expression of the more abstract structure of the site. The skeleton might define the placement of the interface elements on our checkout page; the structure would define how users got to that page and where they could go when they were finished there. The skeleton might define the arrangement of navigational items allowing the users to browse categories of books; the structure would define what those categories actually were.
The Scope Plane
The structure defines the way in which the various features and functions of the site fit together. Just what those features and functions are constitutes the scope of the site. Some sites that sell books offer a feature that enables users to save previously used addresses so they can be used again. The question of whether that feature-or any feature-is included on a site is a question of scope.
The Surface Plane
On the surface you see a series of Web pages, made up of images and text. Some of these images are things you can click on, performing some sort of function such as taking you to a shopping cart. Some of these images are just illustrations, such as a photograph of a book cover or the logo of the site itself.
The Strategy Plane
The scope is fundamentally determined by the strategy of the site. This strategy incorporates not only what the people running the site want to get out of it but what the users want to get out of the site as well. In the case of our bookstore example, some of the strategic objectives are pretty obvious: Users want to buy books, and we want to sell them. Other objectives might not be so easy to articulate

One of the main criticisms leveled at graphical user interfaces by experienced computer users — notably those trained on command-line systems — is that getting to where you want to go is made slower and more difficult by the extra effort that goes into manipulating windows and icons.
