Abstract
Human–computer interaction is a discipline concerned with the design, evaluation and implementation of interactive computing systems for human use. The field formally emerged out of computer science, cognitive psychology and industrial design through the 1960s, formulating guidelines for the development of interactive computer systems highlighting usability concerns for improved interfaces. Computing devices are becoming more prevalent and integrated into both our social and work spaces.HCI therefore plays an important role in ensuring that computer systems are not only functional but also respect the needs and capabilities of the humans that use them.
HCI encompasses not only ease of use but also new interaction techniques. It involves input and output devices and the interaction techniques that use them; presentation of information, control and monitoring of computer’s actions and the processes that developers follow when creating interfaces. In this seminar, emphasis is laid on the movement of a user’s eyes which can provide a convenient, natural, and high-bandwidth source of additional user input. Some of the human factors and technical considerations that arise in trying to use eye movements as an input medium and the first eye movement-based interaction techniques are discussed in this section.

*
*
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

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

3. Introduction
Human
•The end-user
•The members of an organization
Computer
•Hardware
•Software
Interface
• A point where two objects meet.
• A point where the human can tell the computer what to do.
• A point where the computer displays the requested information.
3
4. What is HCI?
• A process of information transfer
User to Machine
Machine to User
• HCI is also referred to as Man Machine Interaction.
• HCI is what the user sees and includes:
How the system looks like?
How the system accepts input from the user?
How the system responds to user input?
4
5. Types of Interfaces
• Command Line Interface (CLI)
A CLI displays a prompt, the user types a command on the
keyboard, the computer executes the command and provides
textual output.
• Menu Driven Interface
The user has a list of items to choose from, and can make
selections by highlighting one.
Graphical User Interface (GUI)
Uses windows, icons, menus and pointers (WIMP) which
can be manipulated by a mouse (and often to an extent by a
keyboard as well).
Natural Language Interface
Can range from simple command systems to voice activated
text processing. Commands are spoken in “normal” language.
5
6. Command Line Interface
Advantages
Very flexible with the use of “switches” (options)
Good for “expert” users - can quickly access commands
Uses the fewest system resources
Disadvantages
Requires the user to learn “complex” commands or language
“Hidden” features i.e. if the command is unknown we cannot
make use of that feature
Not very good for novice users
6
7. Menu Driven Interface
Advantages
No need to learn complex commands/language
Easier for a novice to learn/use
Ideal when there are a limited number of options (efficient)
Disadvantages
Can be frustrating for experienced users i.e. the command they
want to use is buried 5 levels deep.
User interface may be limited by screen space and number of
options available.
7
8. Graphical User Interface
Advantages
Most suitable interface for inexperienced or novice users
Many generic packages for a GUI will share common
features
Disadvantages
GUIs use more system resources than other types of interface
8
9. Natural Language
Interface
Advantages
No training required
Can be quicker than keyboard entry
Hands-free
Can be used by the disabled
Disadvantages
Emerging technology – still contains “bugs”
Difficulty in dealing with homonyms
Difficult to recognise all the different ways of saying things
(and regional dialects)
Artificial languages are often more precise
9
10. Existing Technologies
The existing interfaces differ in the degree of complexity
both because of degree of functionality or usability.
The user activity has three different levels:
Physical
Cognitive
Affective
The existing physical technologiesfor HCI basically can
be categorized by human senses.
These devices are basically relying on three human senses:
vision, audio, and touch.
10
11. Advances in HCI
The new advances in HCI can be categorizedin 3sections:
wearable devices, wireless devices, and virtual devices
Examples:
GPS Navigation Systems
Military super-soldier enhancing devices
PDA
Canesta Keyboard(QWERTY pattern)
11
13. Architecture
Architecture of any HCI systems is identified by:
Number of inputs and outputs in the system
Diversity of inputs and outputs in terms of modality
Workings of these diverse input and output for
interaction purpose
Basedon differentconfigurationand design ofinterface,HCI
systems can be divided into:
Unimodal HCI system
Multimodal HCI system
13
14. Limitations
Not a natural way of human interaction
Usually designed for the „average‟user
Fails to cater to the needs of a diverse category of people
Difficult to use by disabled, illiterate and untrained people
Cannot provide universal interface
17. Conclusion
Quality of system depends on how it is represented and used
by user. Therefore, enormous amount of attention has been
paid to better designs of HCI. Virtual reality can be the
common interface in future. UbiComp is trying to embed the
technology in the environment and make it invisible at the
same time. Natural and Neural Interfaces are the future of
Human-Computer input interfaces.
