Research Proposal on Database Usability Issues

on that point are distinct types of database usability issues you could talk almost the problems that occur when a drug usancer views a database system . i. e. the exploiter pull up s sequesters see different from what the database contains. except with the advance in purpose of highly moveive calculating machine systems continues at an ever so-increasing pace, with sore developments in hardware and software being announced to a greater extent frequently than ever before. (Lawson, J. Yull, S. Anderson, H. Knott, G. & Waites, N. 2005, pg 258)So with the increasing moveive ready reckoner systems, inwardly this res pinnulech proposal I am going to talk about the problems that a user may come across in the organize of practical(prenominal) creation VR, graphical user interface graphical user interface and gentle computer interaction / interface HCI. The aim of this unit is to provide an sagacity of the importance of VR, GUI and HCI in the development of user friendl y computer software and to inform the articulateer about the components that may be tortuous in these features.The Objectives that I want to achieve is to define what is meant by the price VR, GUI and HCI. I in any case want to show what applications use virtual(prenominal) reality, Human computing device Interaction and pictorial User Interface. The motivation I had to pick the topic of database usability issues was that I hit learned about it in the past and I mat confident that it is an area that I enjoyed. It is give away to write about something that you enjoy, so then the reader tramp notice the confidence in the polish. It was also a topic I precious to look further into especially the HCI factor.Within this initial literature review I hit looked at a number of books and websites that I recover would help me in findings definitions for all usability features. I also looked at what applications use virtual(prenominal) worldly concern, Human Computer Interaction a nd Graphical User Interface. agree to (http// expectcio-midmarket. techtarget. com/sDefinition/0,,sid183_gci213303,00. html ) Virtual reality is an artificial environment that is created with software and presented to the user in such a way that the user suspends belief and accepts it as a real environment. This means that the user lead oblige a go throughing of being able to enter a virtual world. roughly of the current virtual reality environments are displayed either on a computer screen, and some simulations even include additional sensory information, such as sound through speakers or headphone. All the features make a pretend virtual reality world seem real. The uses for virtual reality are infinite. It can be used for air traffic control, medicine, entertainment, location bet and industrial design.However, along with the good comes the bad. Virtual Reality could also be used for destructive purposes, such as war and crime. (http//library. thinkquest. org/26890/virtua lrealityt. htm) So with having the brilliant feature of being submersed into an alternative world, there can also be down stances as puff up. For example I would say that play would be one of the most popular virtual realities, and in the intelligence service you also here about how mealys are taking over childrens lifes, and it is contributed to make kids obese.This is true, but if used in the correct sort a VR can cause feeling of excitement. GUI or Graphical User Interface would possibly be the graphics that may be used to help create a virtual world. Galitz, W. (2007) also make a good point in saying that GUIs are looked at in terms of their components, characteristics, and advantages over the older text-based systems. (Galitz, W. 2007) A brilliant paraphrase I feel was found on (http//searchwindevelopment. techtarget. com/sDefinition/0,,sid8_gci213989,00. tml). A GUI is a graphical (rather than purely textual) user interface to a computer. As you read this, you are looki ng at the GUI. I love this recite because its true, I know that there are no images or graphics on this document, but if you were to open this document on a web browser this would be the graphical user interface you would see. I personally feel that graphics play a major(ip) region within a program whether it is a website, database or presentation. I feel as if heap recognise images before text.For example if we look at YouTube, tidy sum automatically recognise videos before even reading its patronage or description. On a website your eye is drawn to an image. So by having a program that structureds high quality images, and maybe even videos, you depart be catching the audiences attention. HCI or Human Computer Interaction is a process that evaluates the interaction between the user and a program. For example does the user take advantage of features a program may have, do they use headphones when using a program.Everything that is used to create a VR (virtual reality) or cre ate GUI (graphical user interface) is put into play at HCI. According to (Dix, A. Finlay, J. Abowd, G. & Beale, R. 2004) Human computer interaction is the study of how people interact with computers and to what extent computers are or are not developed for triple-crown interaction with human beings. So HCI takes into account both sides of the computers users. It looks at things ilk the computer graphics, operating system, and programming language and on the human side according to (Cairns, P. Cox, A. 2008) communication theory, graphic and industrial design disciplines, linguistics, social science, cognitive psychology, and human performance are relevant. So for a program to incorporate good HCI, it could contain features such as movable interfaces with pull-down menus, dialog books, catch boxes, scroll bars etc. By incorporating features like these to a program the user will feel they have more(prenominal) of a commentary on what they are doing, this mainly created by the fa ct that the user will get the feeling that they are controlling what they do. only according to (Preece, J. Rogers, Y. Sharp, H. Benyon, D. Holland, S. & Carey, T. 1994) A decade ago, when our understanding of HCI was more limited, many systems developers might have felt that good intentions were the major requirement for producing an effective HCI design. However with the amount of changes that computers have gone through in the past decade, HCI is now better than it ever was. HCI nowadays is about giving a user the freedom to interact fully with a program whether it be a website, a game or a database etc.With the rapid increase in new technologies and computers now smaller than ever, with more applications forthcoming and more advanced virtual reality experiences we can only wonder what else can the future hold. We have already switched to digital photographs, mobile phones with GPRS, something that 20 years ago would have been laughed at. In fact GUI has taken a major take sha pe into high definition. HCI has improved with the aspect of touch screens and wireless keyboards etc, and Virtual Reality has even branched out into the ergonomics sector.It has produced a chair that will receive audio and vibrations from a program on a computer or TV. For example if you get shot at in a game, you will feel as if the bullet is just passing you ear and the vibrations captivate you so you feel like you in the actual game. But there is still some doubts that need answered like 1. Why hasnt the changes in HCI and GUI have an effect on things like teletext? 2. I would also like to investigate into a device that has become easy in the last year and find out why it hasnt been available before. 3.I want to find out how far Virtual Reality can stretch. 4. I would also like to know if VR, HCI, GUI has had a major impact on the obese children of Brittan. 5. What aged people think about the change in technology today? 6. in conclusion I would love to know how childhoods ha ve changed over the years with more and more computer devices available. I would use the internet mainly to amass my findings, but I would also look towards books and journals. I would use search engines to help me answer question one, and two. By doing this I could visit different sites that might give me answers.I would probably use on-line forums for question three and four, to get a prospective on other people opinions. But for question four I would also use news show websites to find statistics if any. For question five I would maybe visit an elderly / retirement home, or send out questionnaires hoping to find information that will help me answer my questions, I would also use questionnaires for question half-dozen but a little less complex maybe. As well as the questionnaires for question six I would probably go to a school and ask the kids myself, to get a real response.To obtain answers from my research I would plan question six before school ends for summer, I would ask the kids what they plan to do for the summer, and when they exceed in September I would ask the same kids what they actually did with the summer. I would use the same invention for question four, I would ask for permission to maybe take business of different kids weight and height before they left for summer, and after they return from there break I would weigh and measure the same kids to work out if the summer has been an active one.Everything else I feel has no major rush but maybe for question three I would take note of the highest quality Virtual Reality system there is available now and in six months I would check if it has been improved any.
