o At least one scenario from a user's perspective.

User: I suggest that your system must be a user friendly, can include all the data’s needed for our business.

* Can retrieve and view data or record. * Must be simple, directly and can modify. * The design must not be

o [20 pts] Rationale:

Advantages | Disadvantages | * User friendly | * Offline transaction | * View and retrieve data | | * All their requirements are met | | * Functional design as well as the GUI design | |

o [20 pts] Changes to your requirements:

In terms of design there’s a changes happen we improve the design of our prototype in order to be more presentable to the users. We alternate those requirements which are not useful into highly basic requirements.

Prototype Description
The type of prototype that we used was evolutionary prototyping because the main goal of using it is to build a very robust prototype in a structured manner and constantly refine it and evolutionary prototyping is a functional system. Although they may not have all the features the users have planned, they may be used on an interim basis until the final system is delivered. For a system to be useful, it must evolve through use in its intended operational environment. A product is never "done;" it is always maturing as the usage environment change we often try to define a system using our most familiar frame of reference in which where we are now. We make assumptions about the way business will be conducted and the technology base on which the business will be implemented. A plan is enacted to develop the capability, and, sooner or later, something resembling the envisioned system is delivered. It is not unusual within a prototyping environment for the user to put an initial prototype to practical use while waiting for a more developed version…The user may decide that a 'flawed' system is better than no system at all. To minimize risk, the developer does not implement poorly understood features. The partial system is sent to customer sites. As users work with the system, they detect opportunities for new features and give requests for these features to developers. Developers then take these enhancement requests along with their own and use sound configuration-management practices to change the software-requirements specification, update the design, recode and retest. Criteria | Features | Feedback | Visibility of system status(Feedback) | The system should always keep users informed about what is going on, through appropriate feedback within reasonable time. | | Match between system and the real world(Metaphor) | The system should speak the users' language, with words, phrases and concepts familiar to the user, rather than system-oriented terms. Follow real-world conventions, making information appear in a natural and logical order. | | User Control and Freedom(Navigation) | Users often choose system functions by mistake and will need a clearly marked "emergency exit" to leave the unwanted state without having to go through an extended dialogue. Support undo and redo. | | Consistency and standards | Users should not have to wonder whether different words, situations, or actions mean the same thing. Follow platform conventions. | | Error prevention(Prevention) | Even better than good error messages is a careful design which prevents a problem from occurring in the first place. Either eliminate error-prone conditions or check for them and present users with a confirmation option before they commit to the action. | | Recognition rather than recall (Memory) | Minimize the user's memory load by making objects, actions, and options visible. The user should not have to remember information from one part of the dialogue to another. Instructions for use of the system should be visible or easily retrievable whenever appropriate. | | Flexibility and efficiency of use(Efficiency) | Accelerators -- unseen by the novice user -- may often speed up the interaction for the expert user such that the system can cater to both inexperienced and experienced users. Allow users to tailor frequent actions. | | Aesthetic and minimalist design (Design) | Dialogues should not contain information which is irrelevant or rarely needed. Every extra unit of information in a dialogue competes with the relevant units of information and diminishes their relative visibility. | | Help users recognize, diagnose, and recover from errors (Recovery) | Error messages should be expressed in plain language (no codes), precisely indicate the problem, and constructively suggest a solution. | | Help and documentation(Help) | Even though it is better if the system can be used without documentation, it may be necessary to provide help and documentation. Any such information should be easy to search, focused on the user's task, list concrete steps to be carried out, and not be too large. | |…...

Human Computer Interaction

...In designing any interface to be used with an information system, one must be clear, concise and unambiguous, in manners of text, or else risk losing the person performing interaction. One thing that will frustrate a user quicker than anything is not being able to find help when it is needed. We will discuss three aspects of text in the interface redesign of the KUCampus Course Landing page; they are commentary text, help text and hypertext. Commentary text should allow a user to see a system state or the functionality behind a system. As an example, if a user places the mouse over an icon that has a picture of a pair of scissors; the commentary text would be, cut, hopefully. If anything other than cut is displayed the user may be confused, since the pair of scissors is generally accepted as the cut icon. For the redesign of the KUCampus Course Landing page, I will endeavor to utilize generally accepted commentary text for all icons, and utilize common sense logic in relation to commentary text for all buttons and menus. Help text is critical for any interface design and/or redesign. Users at some point in their use of a computing system will come across stumbling blocks and require help. Providing help in a way that will benefit the user and keep them satisfied with the interaction is paramount to a healthy program. Microsoft defines help into four categories: Contextual Help, Procedural Help, Reference Help and Conceptual Help. (Heim, 2008) The Contextual......

Why Do We Care About Human-Computer Interaction?

...1 Case   ITM 433 – Computer-Human Interaction Module 1: Why do we care about human-computer interaction? Case Assignment: Discuss the application of speech recognition as a tool for Human Computer Interaction Definitions Before getting too far into detail, here are some definitions this paper is based on. Human-Computer Interaction (HCI) is summarily, and loosly, defined as the interaction between people (users) and computers and can be referred to in several different manners. For instance; Computer-Human Interaction (CHI) or Human-Machine Interaction (HMI) are both virtually interchangeable with HCI. The phrase “speech recognition” is rarely, if ever, used outside the context of computer science. Speech recognition refers to the ability of computer-based software to convert spoken words into written (typed/digital) text. Together – HCI/CHI/HMI, etc., insert your acronym of choice but HCI will be used throughout this paper – HCI and speech recognition represent the present and rising future of end-user functionality. The next big thing will be the ability of computers or machines to read your mind instead of verbally instructing it to carry out your bidding… that is sarcasm, of course. However, this current reality of speech recognition software was not stumbled upon and did not happen by chance.   A Short History The lever is widely regarded as the first “machine” “invented” and implemented by humans. Regarding human inventions, not much......

A.I. and Human Interaction

...1 INTRODUCTION People have been thinking about artificial intelligence since before the 1950's. It was in that time that Alan Turing proposed the “Turing Test”. Which measures how well a computer can think by having an interrogator ask it and a human questions. If the interrogator cannot determine which is human and which is machine then the machine has passed the Turing test.[1] Its been 15 Years since Deep Blue beat the world chess champion Gary Kasparov. And since then chess computers have continued to improve dominate. Most notably Deep Fritz the desktop chess program beating Vladimir Kramnik.[2] Just 2 years ago IBM developed “Watson” a computer that played Jeopardy and beat former winner Ken Jennings and Brad Rutter.[3] With A.I. Improving the question of how intelligent machines should be used to interact with humans becomes more and more relevant. In what ways can A.I. be used to interact with people and what moral implications exist? 2 A.I. IN THE PRIVATE SECTOR Intelligent machines are already being used by many private companies. These are in the forms of autopilot, data mining, facial recognition, etc. Those are not form of A.I. that humans interact with. There some modern uses of A.I. Humans interact with such as automated systems and there will be more as technologies develop. Something else that will come along with the development of artificial intelligence is robots as domestic helpers. And both of these will bring with them many ethical questions......

Business people in developing and industrialized nations alike are seizing the opportunities being presented by three forces: information and communication networks, globalization, and the growth of the private sector and market economies. Businesses are taking advantage of new technological advances in order to communicate with fellow employees, potential clients and developing buyers within their market by using the telephone, cable, internet, debit/credit cards and computer networking. Businesses have found that it is very difficult to manage operations without proper access to telephone lines, computers and the ability to connect to the internet. Internet providers are expanding their capabilities to businesses and allowing them to access their laptops via wireless cards when wireless internet connection is not available. Many businesses have transferred most of their marketing power to on-line advertising and merchants such as Ebay, Amazon, individual web sites.

Real Time Hand Tracking for Human Computer Interaction

...Real-Time Hand Tracking for HumanComputer Interaction Ayush Tripathi, Kanishk Puri, Nilesh Srivastava, Prateek Dham (Students) Mrs S.S Dhotre(Professor) Computer Science Department Bharati Vidyapeeth Deemed University College of Engineering Pune, Maharashtra(India) Abstract- The proposed work is part of a project that aims for the control of a mouse based on hand gesture recognition. This goal implies the restriction of real-time response and unconstrained environments. This is basically a vision based skincolour segmentation method for moving hand in real time application [3]. This algorithm is based on three main steps: hand segmentation, hand tracking and gesture recognition from hand features. For the hand segmentation step we use the colour cue due to the characteristic colour values of human [1]. The hands are recognized by the computer using the skin colour as one of the basic features for the hand recognition. The important feature is the accurate segmentation of hands [3]. I. Introduction Nowadays, the majority of the human-computer interaction (HCI) is based on mechanical devices such as keyboards, mouse, joysticks or gamepads. In recent years there has been a growing interest in a class of methods based on computational vision due to its ability to recognise human gestures in a natural way .These methods use as input the images acquired from a camera or from a stereo pair of cameras. The main goal of these algorithms is to measure the hand configuration...

Examine Human Computer Interaction Theories and Principles

...Examine Human Computer Interaction Theories and Principles IT302 |Human Computer Interaction Interaction Framework Four main parts of the Execution/Evaluation Action Cycle framework A framework is how we think about a process. Within the context of this class this framework focuses on how we interact with computers in the scope of the process or project. Since the first business started in our earliest history stakeholders have looked for ways to improve and be more successful. Since the invention of computers people have been looking at ways to have these devices help improve this process. The Execution/Evaluation Action Cycle (EEAC) was presented by Donald Norman in 1988. His concepts explored the nature of how actions can be structured into four basic parts (Heim, 2007, p. 42): Example of how the chosen framework might actually work When starting any large scale project a team of stakeholders typically start off with an end goal. With tools such as Microsoft Project and others each stage of the frame work can be mapped out and help keep the project on task. How it fits each part of the framework One important point is that this framework is a cyclical process that in truth does not have an end point until the stakeholders have reached a point where they are satisfied with the results and can be revisited at a later point.

...Future of Computers and Humans What does the future have in store for the human race? The question cannot be accurately answered because it would be impossible to describe precisely what hasn't actually occurred in time. Using facts from the past and making a logical decision based on them is the closest we come to an accurate prediction of the future. "Robot Renaissance � by Danylo Hawaleshka and "The Lonely Planet � by John Ibbitson contain predictions of the future world we could live in. While they both seem to forecast a different aspect of the future, Danylo focusing on robotics and the future of electronics and Johns comparison of the human population and social patterns, there is a similarity between the two topics that could link them and form another prediction that has scared some and excites others. Will there be a decline in human life and a rise in the humanoid, a robotic version of us, and what will occur if this happens?Computers started a new age when they first began to make an impact on society, even the arrival of the simple calculator, the Z1, which was built in Germany around 1931 by Konrad Zuse had the potential to change the world.

Human Computer Interaction

...Human and Computer Interaction Short-Term Memory and Web Usability by JAKOB NIELSEN on December 7, 2009 Topics:  * Human Computer Interaction Summary: The human brain is not optimized for the abstract thinking and data memorization that websites often demand. Many usability guidelines are dictated by cognitive limitations. People can't keep much information in their short-term memory. This is especially true when they're bombarded with multiple abstract or unusual pieces of data in rapid succession. Lest designers forget how easily users forget, let's review why our brains seem to be so weak. Human beings are remarkably good at hunting the woolly mammoth. Our ancestors did fine work in exterminating most mega fauna from Australia to North America armed with nothing better than flint weapons. (In today's more environmentally conscious world, we might deplore their slaughtering ways, but early humans were more interested in catching their dinner.) Many of the skills needed to use computers aren't highly useful in slaying mammoths. Such skills include remembering obscure codes from one screen to the next and interpreting highly abbreviated form-field labels. It's no surprise that people are no good at these skills, since they weren't important for survival in the ancestral environment. The human brain today is the same as the human brain 10,000 years ago. Indeed, I thought of using the title "Designing Websites for Cavemen" for our new course on how psychology......

The Effects of Social Networking on Human Interaction

...The Effects of Social Networking on Human Interaction
 What is social networking? According to dictionary.com, social networking is defined as “the use ofwebsites or other online technologies to communicate with people and share information, resources, etc.” Social networking has become a must for many aspects of life. Human interaction often involves the discussion of something that appeared on a social networking website or the exchange of usernames for one to be found on a website. Many schools are incorporating the use of sites such as Facebook to keep students updated on events and homework, just in case the instructor had forgotten to mention something during class that day. A group of friends can make plans together over a group conversation since the number of callers in a multi-way call is limited. Clubs or organizations who need to spread the word of an upcoming event merely have to make a website or post a notice online and have people share it. There is less of a need for paid printed advertisements. Institutions and companies now give the option of applying online. But what has social networking done to the way people interact with each other? The way social networking changes how one interacts with others is no different from the way actual interactions change a person’s ability to socialize. Some, through social networking, have been able to create deeper and stronger relationships with other people, whether that relationship previously existed in some form......

Upon some students’ request, Cookienator intended to start up a website to publish cooking steps and recipes so that students can learn directly from home and save travelling cost and time. Also, not all students have the same preference towards meals and cooking methods. Each individual have their own likes and dislikes so by giving them options to learn by themselves allows them to fully utilize the resources provided and Otoke group is chosen by cookbook magazine to set up a website for Cookienator. Our project includes designing a website where those who are learning from home can successfully understand and easily follow the instructions and guidance provided. There are many other websites and applications that have similar functions but very few of them are successful. The reason behind this is not that most users dislike the meals available; mostly it is because the instructions are not clear enough, and user finds it difficult to find the suitable dishes to prepare. Other problem will be taking into considerations and improvise based on user needs. The webpage we will be designing intend to meets users’ needs and well organized to provide convenience for users.

...Computers becoming Human How similar can computers come to being human I believe scientist can make computers similar to humans to a certain extent. I believe we have come a long way in improving artificial intelligence and learning algorithms in order to create free thinking machines and robots. Humans are much more than just thinking machines. The major problem scientist face is no real understanding of how the brain neurons and action create consciousness. We really do not know what consciousness is and how to replicate it. They are working on it however that would be a heavy task. We do not know what emotions consists of or how to measure it. This is not a tangible variable. Will scientists' study of human emotions ever make computers and humans essentially indistinguishable? This is the million dollar question. Human research has been rewarding in the last 100 years, however I believe there is a finite limit to human understanding. I believe consciousness and emotions are the last frontier to creating a human being from scratch. I am not sure we will be able to reverse engineer the invisible mysteries of the mind. How important is it that they look similar to humans? I believe it is important that the robots look human like. Some of the early machine looking robots added to the fear.

Introduction to Human Computer Interaction

...Introduction of Human Computer Interaction Human computer interaction is communication between user and system, and is the study of the way in which computer technology influences human work and activities. With the rapid advancement of technology, our lives almost depend on computer or any kind of machine. For example computer, Global Positioning System (GPS), cell phone, and even for tuning musical instrument you have a digital device that helps tune your instrument. Therefore it is very important that the interface of any device should be very user friendly, meaning the person who does not have much knowledge of system should be able to use it. Because not all of our populations are computer or technology literate, but still they have to use it because of requirement and necessity (Dix, A. 2009, pp. 1327-1331). Analysis of Google Home Page The strength of Google is the simple look and feel which every single user can access and gain useful information. The speed of the search engine is amazing and can gain any information within no time. Google has the provision to integrate with various languages and its localized search is an added features compared to other search engines. The information is well organized. Google’s products are its major strength which has created a huge user base. This enhances the trust to its customers and shareholders.

This allows the user to see that the page is still working properly, but beyond the page, this also allows the user to see if their computer or browser is still working properly. If the picture changes, then everything is working fine. If it stays one image for too long, then there might be something wrong with the website, their computer, or web browser.

Human Interaction with the Environment

...How Do You Think Humans Interact With the Environment? Introduction The term environment has different definitions depending on the context and the people involved. Culture and technological advancements of a people are some of the criteria used to define the term environment. The Merriam-Webster dictionary defines the environment as the “complex physical, chemical, and biotic factors that act upon and organism and ultimately determine its survival.” An important point to note from this definition is that, in this particular case, the human being is the organism whose survival is dependent on the environment. Among all living organisms on earth, none has influenced the environment as humans. In their daily activities, people build houses, roads, cities, dams, and carry out various other activities in order to make life more comfortable. Consequently, human beings adapt, depend on, and modify the environment in order to make life more comfortable. This has resulted in consequences such as climate change that have only recently been appreciated by the global community. It is an irrefutable fact that human beings cannot survive without the environment. Therefore, the topic of how humans are interacting with the environment is becoming an increasingly debated topic. This paper seeks to discuss how humans interact with the environment and the impacts that have resulted from these interactions. Finally, a solution to the challenge brought about by these interactions will be......
