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...

...process 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...

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...

...Limitations of Study The best option of discovering the most usability problems of a website is through merging several information gathering methods. Personas are only good as the research put into them and scenarios are not meant to discover a full set of requirements (Sharp, Rogers, Preece, 2007, p.506). According to The Research-Based Web Design and Usability Guidelines Book, the first chapter states that a successful project needs at least four different sources of information to be successful (Bailey, Koyani, Nall, 2004) Due to the short time span of our project, we were not able to evaluate the entire website and as a result our team only evaluated a small sample of information within the five main sections. With five members on our team Neilsen (1992) found that evaluators discover about 75% of the total usability problems. Our team used heuristic evaluation as the sole inspection method which could at times be a disadvantage to fully depend on. Heuristic evaluations may not scale well for complex interfaces (Slakovic & Cross, 1999). Since our team consisted of only five members, a small number of evaluators may not find most of the problems in complex interfaces, like ipl2.org, and may miss some serious problems. Also the heuristic evaluation limited each team member to only emulate the users. Actual user feedback can only be obtained by involving potential users in the heuristic evaluation. Lastly heuristic heuristic evaluations may be prone to reporting false alarms...

...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...

...term memory for about 18 seconds without paying attention to it. After this period, information can be lost or replaced with new incoming information in the short term memory. Whenever user want to interact with the world using the information from the short term and long term memory, a third type of memory i.e. working memory (WM) comes into picture which helps us make decisions, and remember and retrieve facts. Since user actively use these memories while interacting with the computer systems, a designer have to carefully consider their respective limitations while developing the interface for optimal performance. User satisfaction is one of the key aspects that measures the success and popularity of a computer system or website. One important factor that contributes to user satisfaction is the response time of the system. Response time is generally measured as the number of seconds it takes from the moment a user initiates an action, usually by pressing the Enter Key or a mouse button, until the computer begins to present the results (Shneiderman B and Plaisant C., 2009). Once the system response is completed and observed by the user, he/she will start thinking on the next action in the process. Time taken between the computer’s response and the user’s initiation of...

...The Computer Mouse The computer mouse first came about in the early 1980's. The idea being that the movement from the users hand could be turned into signals that the computer could read moving the cursor around and also allowing the buttons to function when pressed. Today there are a few different types of computer mice on the market. These being the mice that use the traditional tracking ball, the optical mouse and the mouse that has no physical connection to the computer. The most common mouse found near a computer today is the traditional mouse that uses the tracking ball. This is the same method as was used when the mouse was first released in the 1980's. The track ball inside the mouse touches the desk when it is moved. When the ball moves the motion is detected by two perpendicular axis, one which detects x axis directional motion and the other y-axis direction motion. Tracking Ball Perpendicular axis motion detectors Hole in which track ball would sit The diagrams above show the tracking ball and the hole in which the tracking ball sits. You can see the x and y axis motion detectors of which the y-axis detector lies 90° from the x-axis detector. These motion detectors are also known as rollers. When the mouse is in use the tracking ball moves moving one or both of the rollers. Each roller is connected to a shaft, which spins a disc. The disc has holes in it and next to the disc is an infrared LED and an infrared...

...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.
