STAR MODELSTAR MODEL

It is more appropriate foruser interface design

process.The emphasis of

the star model is on

evaluation.The starmodel also implies that

designing user interfaces

can be either bottom-up

or top-down or

both,indicating thattheres no right or wrong

approach in starting the

design process.

USABILITY

Usebility is how well users can learn to use a product and how quickly and easily they

can accomplish tasks & how satisfied they are with the process.It is more

appropriate for user interface design process.

Usability Measures:-

Ease of learning- How fast a user who has never used the site before canlearn it well enough to accomplish tasks.

Efficiency of use- How fast the user can accomplish tasks having learned the system.

Memorability- Having used the system before,how well the user remembers it

without having to start over and learn it again.

Error frequency and sevrity- How serious and often users make errors and how users

recover from these errors.

Subjective Satisfaction- How much the user likes using the system.

USABILITYUSABILITY

. Analysis- Analyze everything that has an impact on site,paying special attention to usersand their needs

Prototype- It is used for testing.

Evaluate- The designs should be evaluated and enhanced as often as needed.

Design- It is important to evaluate the design to criteria of effectiveness and efficiiency.

Site Build- Built the site using standard compliant valid coding to develop a good,useful

site.

Post Launch- After the site was launched,ongoing usability checks should be performed.

User feedback gives a great opportunity to further enhance the site.

ERGONOMICS- WHAT IS IT?

Derived from two Greek words:

Nomoi meaning natural laws

Ergon meaning work

Hence, ergonomists study human capabilities in relationship towork demands

Ergonomics is the science of co-ordination the physical and

psychological aspects of human beings with their working

environment.Although computers present us with greatopportunities for making our work easier, they do present some

health and safety risks if used incorrectly. The science of

ergonomics tells us how to use computers correctly.

16/26

3 MAIN ERGONOMIC PRINCIPLES:

1. Work activities should permit worker to adopt

several different healthy and safe postures.

2. Muscle forces should be done by the largestappropriate muscle groups available

3. Work activities s/b performed with joints at about

mid-point of their ROM (esp. head,trunk,UE)

Research related to Human Computer InteractionResearch related to Human Computer Interaction

The HCIL has conducted a broad range of research over the years,and continues to pursue several areas in depth.

Some of the emerging areas of research in Human Computer

Interactionare given below:

Communities Design Process

Digital Libraries

Physical Devices

Research TopicResearch Topic CommunitiesCommunities

wSocial Computingis a new field of HCI that focuses on the design, evaluation, maintenance and

social interaction via digital technology. Its roots lie in computer science, information systems,

technology and psychology just like HCI. In addition social computing draws heavily on sociology,

social psychology, anthropology, communication, education, economics, marketing and, of course,

HCI.

wOnline Communities consist of people who come together online and interact socially to achieve

some kind of goal. Community is not the same as the software platform that supports it - an

obvious fact for some, but unfortunately not everyone. Many e-commerce sites fail because

developers think that by adding community software they are creating a community. Software

alone is not enough, nor is usability; attention must be paid to supporting social interaction (i.e.,

sociability) through a combination of software design and social support.

Research TopicResearch Topic Design ProcessDesign Process

How we design new technologies has a profound effect on what these new technologiesultimately can be. Each time we make decisions about the design process, the final

product or research can dramatically change. The design process of technology is as much

a part of our research at the HCIL as the actual technologies we make. Our research here

is concerned with how we can bring users into the design process. We see the role of users

as everything from active partners, to inspectors or testers, to research participants that

are observed and/or interviewed. We are exploring these roles with users as a way to

better understand and shape the technology design process for the future.

Children are looking at a low tech prototype of a

classroom of the future.

Research TopicResearch Topic Digital LibrariesDigital Libraries

We seek to aid designers of digital library interfaces and web sites in creating

comprehensible, predictable and controllable environments for their users. Our

work on interactive exploration of digital materials goes back to the early research

on Hypertext in 1983 with the development of HyperTies. In our more recent

projects we promote visual previews and overviews to allow users to rapidly

discriminate objects of interest from those not of interest, and to more fully

understand the scope and nature of a digital library.

A library that provides free access to children's books from around the world. By

ensuring access to books from many cultures and in diverse languages, we foster

a love of reading, a readiness to learn, and a response to the challenges of world

illiteracy.

Research TopicResearch Topic Physical DevicesPhysical Devices

While computers are often thought of as consisting of a monitor, keyboard and mouse,there are actually many other possibilities. From cell phones and MP3 players to

medical devices, and even furry robotic animals - we have been exploring the range of

ways that people can interact with computers. Human senses are not limited to vision,

and include touch and hearing. Our research at HCIL on physical interfaces is

concerned with the development of new physical interfaces which broaden the use of

computers outside the standard computer environments. We believe that by changing

the place where users and technolgy meet, we can make new work, play, living andlearning experiences possible.

Projects that can be doneProjects that can be done

1. Shape Writing Technology

Emphasis on how a user can interact with mobile phones, handheld devices,

PDAs and Tablet PCs without a mouse or keyboard.

The ShapeWriter research project was founded in 1999 at the IBM Almaden

Research Center against the backdrop of 1. User computing was moving beyond

the desktop but user interaction, particularly text entry, remains a key challenge to

the future of mobile computing. 2. Writing systems are rarely scientifically

researched or systematically designed but new forms of computing bring forth

opportunities to invent and research novel writing methods. 3. The tension

between ease of use for novice users and high efficiency for expert users,

critically raised and studied in the research of marking menus, should be a

central and general research question in Human-Computer Interaction. Text entry,

being an intense interaction process, is a critical test bed for such research.

2.Web Accessibility

The accessibilityWorks project has created accessibility extensions to the Firefox browser.

These extensions enable Web pages to be changed 'on the fly' to meet individual user

needs.

IBMs accessibilityWorks software transforms the results of HTTP requests using a

combination of both client and server technologies, taking advantage of the major strengths

of each. Key features of the technology are:

- Dynamic manipulation of Web content so that content providers need not rewrite their web

pages to make them available to a wide range of user abilities.

- To provide a unified approach to accessibility, users can apply transformations in

combination to address users who have multiple limitations.

- Personal preferences for page transformations can be applied by logging in to the project's

server from any computer, providing for portability. No special devices are required.

- An easy-to-use interface for setting preferences accommodates users new to computing.
