...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 explains...

...user some kind of visible feedback that the website is actually responding to the user (Nielsen). The St. Thomas undergraduate website successfully follows this principle by using some features to tell the user that the website is responding to their actions. Things like rollover text, rollover navigation tabs, and a changing background image. Figure 1 - Background image change (Source: http://www.stthomas.edu/admissions/undergraduate/) The background images on the page change every few seconds (see figure 1). 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. Most of the navigable links have a roll over text color of white (see figure 2), allowing the user to see that the text is a link. The tabs at the top also use this same rollover color, but when one is clicked to view that certain page’s content, that rollover color stays. Figure 2 - Rollover text color (Source: http://www.stthomas.edu/admissio ns/undergraduate/) Brent Larsen Writ4501 2 Besides the browser’s particular feedback, showing the full link at the bottom or showing the progress of loading a page, the website itself doesn’t show any feedback or loading progress...

...Introduction Cookienator is a local business that runs cooking class at Kuala Lumpur area. There are around 500 active students that attend cooking classes there. 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. Problem Statement We are required to developing a recipe website. Following Problems need to be solved. 1. Purchase List Integration It means when...

...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. Google search indexes has various file formats including the very popular PDF file format and Microsoft Office files...

...Introduction Over the years, Human-Computer Interaction (HCI) research has been trying to increase the good experience and try to reduce bad experiences as much as possibly with technology. The rapid change in technology allows users to use wide range of applications while on the move, however now and then designers ignore the way clients will need to associate with such interfaces while progressing. It is inefficient if an interface has good software but users struggle to relate with it because of a bad design. The design of a user interface must be simple enough so that it can be easy to interact by novice or expert user. A well designed interface is able to empower and support users who require a sense of agency and control. It is important...

In addition, cultural and national differences play a part. Another consideration in studying or designing HCI is that user interface technology changes rapidly, offering new interaction possibilities to which previous research findings may not apply. Finally, user preferences change as they gradually master new interfaces. | UX | User experience design (UXD or UED) is the process of enhancing user satisfaction by improving the usability, ease of use, and pleasure provided in the interaction between the user and the product.[1] User experience design encompasses traditional human–computer interaction (HCI) design, and extends it by addressing all aspects of a product or service as perceived by users. | As...

...of acquiring knowledge and understanding through thought, experience, and the senses. Image based cognitive e-learning is exactly the need of the hour, because, not all the farmers are educated enough to read through the website. This is exactly where images and videos solve the problem. Abstract— Krishi Sahyog is a web-based solution developed to provide basic education about farming techniques and usage of tools. The uniqueness of this project lies in the fact that it takes into account the present day farming scenario. Krishi Sahyog will help the farmers to understand various farming techniques and will acquaint them with the latest tools and technologies by means of video tutorials in regional languages. This Human Computer Interaction project, an e-learning website, is to help them get a hang of the latest technologies and the latest tools albeit not having any basic technical education, which will also make them aware of the market rate, owing to which they will be aware of the current rate of their product as compared to current market scenario. Also, the weather forecast feature will help them plan their crop accordingly. III. PREVIOUS WORK Today, 75% of our population is somehow related to the agriculture and allied activities but still contribution of agriculture to our economy is just 21%. We have attained overall growth of 8% but the growth in agricultural sector is not even 3.5%. One major reason for the poor condition of farmers is – ...

This seminar on ”Blue eyes” technology presented successfully by him towards partial fulfillment of 4 year B.Tech in Computer science and Engineering of Synergy Institute of Engineering and Technology,Dhenkanal under Biju Pattanaik University of Technology. Er.Siddharth Dash (Seminar Guide) Dr.C.Dash H.O.D Dept.of C.S.E ABSTRACT Is it possible to create a computer which can interact with us as we interact each other? For example imagine in a fine morning you walk on to your computer room and switch on your computer, and then it tells you “Hey friend, good morning you seem to be a bad mood today. And then it opens your mail box and shows you some of the mails and tries to cheer you. It seems to be a fiction, but it will be the life lead by “BLUE EYES” in the very near future. The basic idea behind this technology is to give the computer the human power. We all have some perceptual abilities. That is we can understand each others feelings. For example we can understand ones emotional state by analyzing his facial expression. If we add these perceptual abilities of human to computers would enable computers to work together with human beings as...

...Human computer interaction (HCI) is investigated how human being interacted well with computer via the design and implementation of interactive computing. When designing HCI, it needs to consider the physical and metal nature of human being. Besides that, the factor of physical, cognitive and affective should be considered based on human’s characteristics when designing the interfaces. The physical factor can be defined as human interact with computer with the help of physical things such as keyboard, printer, microphone, mouse, touchscreen, etc. In the other way, physical factor is based on human senses which are hearing, seeing and touching. For example, Speech and voice recognition is based on sound concept, haptic devices is emerged from advanced in virtual reality and touch. The cognitive factor is arranging the way of selection for users which allow users easy to use such as menu, option, and list boxes. The selection must be arranging in the way of logically, and alphabetically. Besides that, keyboards shortcut had be created for expert users in order they can efficiently using the software. The...

...Task analysis and human-computer interaction: approaches, techniques, and levels of analysis Abe Crystal School of Information and Library Science University of North Carolina at Chapel Hill acrystal@email.unc.edu Beth Ellington School of Information and Library Science University of North Carolina at Chapel Hill elliv@email.unc.edu ABSTRACT In this paper we critically review task analysis models and techniques. These approaches to task analysis are discussed in order to develop a richer picture of human activity, while analyzing their limitations, general weaknesses, and possibilities for improvement. We consider their ability to determine the appropriate set of atomic actions in a task, their effect on workers’ motivational needs, their support of users’ cognitive and sociocultural processes, and their effectiveness in supporting interface design. We note that the major approaches have focused on very different levels of analysis, and call for greater integration of these different levels in task analysis theory. Keywords Task analysis, cognitive modeling, activity theory. INTRODUCTION Practitioners and researchers routinely advocate building user-centered systems which enable people to reach their goals, take account of natural human limitations, and generally are intuitive, efficient and pleasurable to use (Preece, Rogers and Sharp, 2002). Central to the design of such systems is a clear understanding of what users actually want to do: What...

...HC: Human-Computer Interaction Human–computer interaction (HCI) is concerned with designing the interaction between people and computers and the construction of interfaces to afford this. Interaction between users and computational artefacts occurs at an interface which includes both software and hardware. Interface design impacts the software life-cycle in that it should occur early; the design and implementation of core functionality can influence the user interface – for better or worse. Because it deals with people as well as computers, as a knowledge area HCI draws on a variety of disciplinary traditions including psychology, computer science, product design, anthropology and engineering.
