INTRODUCTION
Interacting with technology has become an essential part of everyday life for the majority of people.
The average user of a computer system is now less likely to understand the technology. Since, there are different types of technology they have to use.
People are busy and may spend little or no time actually learning a new system.
*
INTRODUCTION..(CONT.)
Therefore, computer systems should be easy to use, easy to learn, and with no errors.
To design and develop of such a system is a major concern of HCI
*
WHAT IS HCI?Human-computer interaction (HCI): “is a discipline concerned with the design, evaluation and implementation of interactive systems for human use and with study of major phenomena surrounding them.”
(ACM SIGCHI, 1992, p. 6)
WHAT IS HCI?HCI (human-computer interaction) is the study of interaction between people (users) and computers.
Interaction between users and computers occurs at the user interface
The golden principle in HCI is that “people should come first”.
*
WHAT ..(CONT.)
HCI consists of three parts:Human: could be an individual user or a group of users.Computer: could be any technology ranging from the general desktop computer to a large scale computer system.Interaction: any direct or indirect communication between a human and computer.
*
WHAT ..(CONT.)HCI concentrates on the study of human factors
The study of human factors started during the Second World War by US army.
Usability was born because of badly designed arms that caused “friendly fire” during war.
*
THE HCI CHALLENGE
*
HCI IS NOT ABOUTMaking the interface look pretty
Only about desktop computers (and that goes for computing as well!)
Something that would be nice to do but usually there’s no time for it
*
HCI IS ABOUTUnderstanding the usersUnderstanding users tasksUnderstanding the surrounding environmentGUI requirements gathering and analysisDesign prototypeEvaluate the system
*
THE GOALS OF HCIThe goal of HCI “is to develop or improve the safety, utility, effectiveness, efficiency and usability of system that include computers.”
(Interacting with computers, 1989, p3)
*
THE GOALS OF HCIThe goals of HCI are to produce usable and safe systems, as well as functional systems. In order to fulfill that, developers must attempt to:
Understand how people use technology
Building suitable systems
Achieve efficient, effective, and safe interaction
Put people first
People needs, capabilities and preferences should come first. People should not have to change the way that they use a system. Instead, the system should be designed to match their requirements

The case study discusses the potential of drone delivery and the challenges that need to be addressed before it becomes widespread.
Key takeaways:
Drone delivery is in its early stages: Amazon's trial in the UK demonstrates the potential for faster deliveries, but it's still limited by regulations and technology.
Regulations are a major hurdle: Safety concerns around drone collisions with airplanes and people have led to restrictions on flight height and location.
Other challenges exist: Who will use drone delivery the most? Is it cost-effective compared to traditional delivery trucks?
Discussion questions:
Managerial challenges: Integrating drones requires planning for new infrastructure, training staff, and navigating regulations. There are also marketing and recruitment considerations specific to this technology.
External forces vary by country: Regulations, consumer acceptance, and infrastructure all differ between countries.
Demographics matter: Younger generations might be more receptive to drone delivery, while older populations might have concerns.
Stakeholders for Amazon: Customers, regulators, aviation authorities, and competitors are all stakeholders. Regulators likely hold the greatest influence as they determine the feasibility of drone delivery.
Artificial intelligence (AI) offers new opportunities to radically reinvent the way we do business. This study explores how CEOs and top decision makers around the world are responding to the transformative potential of AI.
9. HOW CAN WE MAKE DESIGNS BETTER?
• Taking into account what people are good and bad at.
• Considering what might help people with the way they currently do things.
• Thinking through what might provide quality user experiences.
• Listening to what people want and getting them involved in the design.
• Using tried and tested user-based techniques during the design process.

USER INTERFACE – HALL OF SHAME
Presents a number of templates
Prints custom award certificates
Good points about the Interface?
Graphical – Mouse Driven
No complicated commands to remember
User gets a preview of the certificate
13. 10/23/2022 Introduction 13
USER INTERFACE – HALL OF SHAME
Why isn’t it usable?
Long help message for a simple ‘selection’ task
Moving the scroll bar changes the template
How many templates?
How are they sorted?
How much to move the bar to select the next template?
Frequent users: How to find a template already used
How would you redesign?
15. 10/23/2022 Introduction 15
THE ERROR DIALOG
We see it all the time
What’s good about the design
of this error box?
The user knows there is an error
What’s poor about the design
of this error box?
Not enough information
The user does not know how to resolve the error (instructions
or contact info)
18. THE UI IS IMPORTANT !
• User interface strongly affects perception of software.
Usable software sells better.
Unusable web sites are often abandoned.
• Perception is sometimes superficial.
Users blames themselves for UI failings.
19. A SURVEY ON BUYING DECISIONS
• A Harris poll
• (reported in the Wall Street Journal 11/8/05) found that ease of use (61%),
customer service (58%), and nohassle installation (57%) are the most important
factors US adults consider when purchasing a new technology product.
20. THE COST OF GETTING IT WRONG!
• User’s time isn’t getting cheaper.
• Design for it correctly now or pay for it later.
• Disasters happen !!!
Therac 25 radiation therapy machine.
Supertanker accident off England
Predator UAV accident in arizona
21. UIS ARE HARD TO DESIGN
• You are not the user
Most software engineering is about communicating with other programmers.
UI is about communicating with users.
• The user is always right.
Consistent problems are the system’s fault.
• But the users are not always right either
They are not the designers
22. WORDS WORDS WORDS
• User Interface (UI)
• Usability
• User Experience (UX)
• Design
• Human Computer Interaction
• Ergonomics
23. UI
•Part of application that allows users
– to interact with computer
– to carry out their task
24. USABILITY
• How well users can use the functionality of the system/application.
• Dimensions…..
Learnability
Efficiency
Visibility
Errors
Satisfaction
26. McCarthy and Wright propose four core threads that make up our holistic experiences: sensual, emotional, compositional,
and spatiotemporal:
The sensual thread. This is concerned with our sensory engagement with a situation and is similar to the visceral level of
Norman's
model. It can be equated with the level of absorption people have with various technological devices and applications,
most notable
being computer games, smartphones, and chat rooms, where users can be highly absorbed in their interactions at a
sensory level.
These can involve thrill, fear, pain, and comfort.
The emotional thread. Common examples of emotions that spring to mind are sorrow, anger, joy, and happiness. In
addition, the
framework points out how emotions are intertwined with the situation in which they arise – e.g. a person becomes angry
with a
computer because it does not work properly. Emotions also involve making judgments of value. For example, when
purchasing a
new cell phone, people may be drawn to the ones that are most cool-looking but be in an emotional turmoil because they
are the
most expensive. They can't really afford them but they really would like one of them.
27. The compositional thread. This is concerned with the narrative part of an experience, as it unfolds, and the way a person
makes
sense of it. For example, when shopping online, the options laid out to people can lead them in a coherent way to
making a desiredpurchase or they can lead to frustrating experiences resulting in no purchase being made. When in this
situation, people ask
themselves questions such as: What is this about? Where am I? What has happened? What is going to happen next?
What would
happen if . . . ? The compositional thread is the internal thinking we do during our experiences.
The spatio-temporal thread. This refers to the space and time in which our experiences take place and their effect upon
those
experiences. There are many ways of thinking about space and time and their relationship with one another: for
example, we talk oftime speeding up, standing still, and slowing down, while we talk of space in terms of public and
personal places, and needing
one's own space.

WHAT IS HCI
Human–computer interaction (HCI) is the study of interaction
between people (users) and computers.
HCI is a discipline concerned with the design, evaluation and
implementation of interactive computing systems for human use.
Human and a computer system interact to perform a task?
task - write document, calculate budget, solve equation, learn about
Bosnia, drive home, make a reservation, land a plane...
30. Good Interface Design 1
SAFELY
EFFECTIVELY
EFFICIENTLY
ENJOYABLY
Tasks can be completed without risk – e.g. flying an
aeroplane.
Being able to do the right task and do it well – e.g.
videoing a TV programme
To carry out tasks quickly and correctly – e.g. at a
cashpoint
Users should be able to enjoy what they are doing,
not be frustrated by the interface – e.g.
educational programs
Users should be able to use an interface:
31. Good Interface Design 2
WHO
WHAT
ENVIRONMENT
FEASIBILITY
Who is going to use the system, what are their
ages, etc.?
What tasks are they likely to want to perform?
Repetitive, complex, simple, etc.
Where is the computer to be used? In a hazardous
or noisy environment?
What is technologically available? Designers
should not add elements to the interface that
cannot actually be used out easily.
There are four considerations for an interface designer:
33. 10/23/2022 Introduction 33
WHY HCI IS IMPORTANT
HCI is not just ‘how big should I make buttons’ or ‘how
to layout menu choices’
It can affect:
Effectiveness
Productivity
Morale
Safety
Example: A car with poor HCI
36. HCI HOW?
• How do we improve interfaces?
1. Educate software professionals
2. Draw upon fast accumulating body of knowledge regarding H-C interface
design
3. Integrate UI design methods & techniques into standard software
development methodologies now in place
37. UI DESIGN/DEVELOP PROCESS
• Tasks of User-Centered Design
• Analyze user’s goals & tasks
• Create design alternatives
• Evaluate options
• Implement prototype
• Test
• Refine
