What are the purposes of the user centered approach?? (172 CH11)

The user-centered approach means that the real users and their goals, not just technology, should be the driving force behind development of a product. As a consequence, a well designed system should make the most of human skill and judgment, should be directly relevant to the work in hand, and should support rather than constrain the user. This is less technique and more a philosophy.

Define real affordances?

Physical objects are said to have real affordances, like grasping, that are perceptually
obvious and do not have to be learned.

Difference B/W Learned helplessness AND Taught helplessness (PAGE 96 CH11)

Failure to perform a task numerous time, in that case you try to perform a task  or using software and you failure aging and aging these to felling of isolation you think this only with you and ultimately this to finical depuration 

Taught helplessness

 While in that stage a lack of understanding at one stage hinder progress toward another stage. In that case you are performing a task and you fail at that task then you balm yourself and because the next task in depend upon on this task you belief you are not performing nest task then you do not try.

Define two reasons for self blaming? 5 marks  PAGE 94

Learned helplessness
the phenomenon called learned helplessness might help explain the self-blame. It refers to the situation in which people experience failure at a task, often numerous times. As a result, they decide that the task cannot be done, at least not by them: they are helpless.

Taught helplessness

While in that stage a lack of understanding at one stage hinder progress toward another stage. In that case you are performing a task and you fail at that task then you balm yourself and because the next task in depend upon on this task you belief you are not performing nest task then you do not try.

Define affordance and type of affordance? PAGE 105 CH12

Affordance is a term used to refer to an attribute of an object that allows people to know how to use it. For example, a mouse button invites pushing by the way it is physically constrained in its plastic shell.

There are two kind of affordance:
• Perceived
• Real

Define speech input?

Speech input is called Speech recognition is the ability of a machine or program to identify words and phrases in spoken language and convert them to a machine-readable format.

 

Define Icon?

A small picture is used to represent a closed window, and this representation is known as an icon. By allowing icons, many windows can be available on the screen at the same time, ready to be expanded to their full size by clicking on the icon. Decrease a window to its icon is known as iconifying the window.

What is mean by “Early focus on users and tasks? PAGE 172 CH12

This means first understanding that the users will be by directly studying their prospective, behavioral, anthropomorphic, and attitudinal characteristics. This required observing users doing their normal tasks, studying the nature of those tasks, and then involving users in the design process.

Which model involves the risk analysis?

The spiral lifecycle model Involves risk analysis and prototyping.

What is relationship among User Model, Conceptual Model and System Image?

Define Persona?

The persona is precise descriptive model of the user (a persona is the description of the user) Persona based on behavioral data gathered from actual user through ethnographic interviews.

 

Whenever a product is designed, Users of the product are one of the main focuses of the design & qualitative interview?

Customers of a product are those people who make the decision to purchase it. For consumer product, customers are frequently users of the product; although for products aimed at children or teens, the customers are parents or other adult supervisors of children. In the case of most enterprise or technical products, the customer is someone very different from the user—often an IT manager—with distinct goals and needs. It’s important to understand customers and their goals in order to make a product viable. It is also important to realize that customers seldom actually use the product themselves, and when they do, they use it quite differently than the way their users do.

Being student of HCI you have to differentiate between the general users & the potential users of the product. CH19
Users of a product should be the main focus of the design effort. They are the people (not their managers or support team) who are personally trying to accomplish something with the product. Potential users are people who do not currently use the product, but who are good candidates for using it in the future. A good set of user interviews includes both current users (if the product already exists and is being revised) and potential users (users of competitive products and non-automated systems of appropriate).

When we type for few hours during our job , our fingers get strain , so there are some key boards that have been designed to get rid of finger strain , Mention the name of such keyboard and also explain what does RSI stands for


QWERTY keyboard, Dvorak Keyboard, Chord keyboards, Phone pad and T9 entry

RSI stand for Repetitive Strain Injury

A web designer is going to design a website of a University:

 A: what ergonomics should he consider? List any 3

 B: How designer can decide characteristics of interaction be included.

 

Usability is broken down into the following goals:

• Effective to use (effectiveness)

• Efficient to use (efficiency)

• Safe to use (safety)

• Have good utility (utility)

• Easy to learn (learnability)

• Easy to remember how to use (memorability)

Utility

It refers to the extent to which the system provides the right kind of functionality so that
user can do what they need or want to do.

Learn ability

It refers to how easy a system is to learn to use. It is well known that people do not like
spending a long time learning how to use a system.

Memorability

It refers to how easy a system is to remember how to use, once learned. This is especially important for interactive systems that are used infrequently.

User experience goals

The realization that new technologies are offering increasing opportunity for supporting people in their everyday lives has led researchers and practitioners to consider further goals.

As well as focusing primarily on improving efficiency and productivity at work, interaction design is increasingly concerning itself with creating systems that are:

• Satisfying• Enjoyable• Fun• Entertaining• Helpful• Motivating• aesthetically pleasing• Supportive of creativity• Rewarding• emotionally fulfilling

 

Write two aspect of usability?

(1)   It involves optimizing the interactions people have with interactive product to enable them to carry out their activities at work, school, and in their everyday life.

(2)   usability in generally regarded as ensuring that interactive products are easy to learn, effective to use, and enjoyable from user perspective

Ethnographic framework especially developed for?

Ethnographic framework has been developed specifically to help structure the presentation of ethnographies in a way that enables designers to user them. This framework has three dimensions

1. Distributed co-ordination

2. Plans and procedures

3. Awareness of work

Before the developing process the designer must understand the requirement of the products? What are requirements? 3marks
Definition of user, business& technical needs

Star lifecycle model is different from waterfall and RAD in ordering and activates how? 5Marks CHP17

Unlike the lifecycle models introduced above, the Star lifecycle does not specify any
ordering of activities. In fact, the activities are highly interconnected: you can move from
any activity to any other, provided you first go through the evaluation activity. This
reflects the findings of the empirical studies. Evaluation is central to this model, and
whenever an activity is completed, its result(s) must be evaluated. So a project may start
with requirements gathering, or it may start with evaluating an existing situation, or by
analyzing existing tasks, and so on.

 

Define?

Avoidance
what would you prefer not to do?
What do you delay on?

Define constructing personas?

Creating believable and useful personas requires an equal measure of detailed analysis
and creative synthesis. A standardized process aids both of these activities significantly.
Process of constructing personas involve following steps:
1. Revisit the persona hypothesis
2. Map interview subjects to behavioral variables
3. Identify significant behavior patterns
4. Synthesize characteristics and relevant goals.
5. Check for completeness.
6. Develop narratives
7. Designate persona types

 

Describe Chord keyboards?
In chord keyboards several keys must be pressed at once in order to enter a single character. This is a bit like playing a flute, where several keys must be pressed to produced with a small number of keys, few keys are required, so chord keyboards can be very small, and many can be operated with just one hand.

What is task with example?

A piece of work to be done or undertaken

Example Duty, Job, labour etc.

 

Which lifecycle model is famous for risk analysis and prototyping and which for long duration and stable requirements? (2)

Ans:- The spiral lifecycle model

The spiral model incorporates them in an iterative framework that allows ideas and progress to be repeatedly checked and evaluated. Each iteration around the spiral may be
based on a different lifecycle model and may have different activities.

Suppose you are a software engineer and developed a project by following waterfall model approach Which flaws do you identify in this approach during project development?(3)

Flaw of waterfall model

One of the main flaws with this approach is that requirements change over time, as businesses and the environment in which they operate change rapidly. This means that it does not make sense to freeze requirements for months, or maybe years. While design and implementation are completed.

 

What is the preliminary vision of the product from each stakeholder perspective?
As in the fable of the blind men and the elephant, you may find that each business
department has a slightly different and slightly incomplete perspective on the
product to be designed. Part of the design approach must therefore involve
harmonizing these perspectives with those of users and customers.

You are a researcher and assigned a task to conduct research for any new product design from stakeholders. You conduct an interview from stakeholder. Which type of information would you collect from stakeholder? (5) PAGE 168


What is the budget and schedule?

The answer to this question often provides a reality check on the scope of the design effort and provides a decision point for management if user research indicates a greater scope is required.

• What are the technical constraints?

Another important determinant of design scope is a firm understanding of what is technically feasible given budget, time, and technology.

• What are the business drivers?

 It is important for the design team to understand what the business is trying to accomplish. This again leads to a decision point, should user research indicate a conflict between business and user needs. The design must, as much as possible, create a win-win situation for users, customers, and providers of the product.

• What are the stakeholders’ perceptions of the user?

Stakeholders who have relationships with users (such as customer support representative) may have important insights on users that will help you to formulate your user research plan. You may also find that there are significant disconnects between some stakeholders’ perceptions of their users and what you discover in your research. This information can become an important decision point for management later in the process.

What is Eyegaze?

Eyegaze systems allow you to control the computer by simply looking at it. Some systems require you to wear special glasses or a small head-mounted box, others are built into the screen or sit as a small box below the screen.

Interactive system has four types. Explain all of them User, system, input and output?

 

As a product designer what you need to do for constructing personas? 

Write all steps: page 194


Process of constructing personas involve following steps:
1. Revisit the persona hypothesis
2. Map interview subjects to behavioral variables
3. Identify significant behavior patterns
4. Synthesize characteristics and relevant goals.
5. Check for completeness.
6. Develop narratives
7. Designate persona types

Which activities must be undertaken to develop a product. 2 marks

In order to develop any product, two major activities have to be undertaken: the designer must understand the requirements of the product, and must develop the product.

What is goal?

The object of a person's ambition or effort an aim or desired result, For example aim objective?

Difference between mental model and conceptual model?

A mental model is the representation that a person has in his mind about the object he is interacting with. A conceptual model is the actual model that is given to the person through the design and interface of the actual product.

Write the use of speech input?

For example, speech input is useful where there is no surface on which to put a keyboard but is unsuitable in noisy condition; automatic scanning is suitable if there is a large amount of data to be generated.

Differentiate customer goals from corporate goals with respect to non user goals.  5 marks

Customer goals

The exact nature of these goals varies quite a bit between consumer and enterprise products. Consumer customers are often parents, relatives, or friends who often have concerns about the safety and happiness of the persons for whom they are purchasing the product. Enterprise customers are typically IT managers, and they often have concerns about security, ease of maintenance, and ease of customization.

Corporate goals

Business and other organizations have their own requirements for software, and they are as high level as the personal goals of the individual. “To increase our profit” is pretty fundamental to the broad of directors or the stockholders. The designers use these goals to stay focused on the bigger issues and to avoid getting distracted by tasks or other false goals
