There are different types of database usability issues; you could talk about the problems that occur when a user views a database system .i.e. the user will see different from what the database contains. But with “the advance in design of highly interactive computer systems continues at an ever-increasing pace, with new developments in hardware and software being announced more frequently than ever before.” (Lawson, J. Yull, S. Anderson, H. Knott, G. & Waites, N. 2005, pg 258)
So with the increasing interactive computer systems, within this research proposal I am going to talk about the problems that a user may come across in the form of virtual reality VR, graphical user interface GUI and human computer interaction / interface HCI.
The aim of this unit is to provide an understanding of the importance of VR, GUI and HCI in the development of user friendly computer software and to inform the reader about the components that may be involved in these features.
The Objectives that I want to achieve is to define what is meant by the terms VR, GUI and HCI. I also want to show what applications use Virtual reality, Human Computer Interaction and Graphical User Interface.
The motivation I had to pick the topic of database usability issues was that I have learned about it in the past and I felt confident that it is an area that I enjoyed. It is better to write about something that you enjoy, so then the reader can feel the confidence in the review. It was also a topic I wanted to look further into especially the HCI factor.
Within this initial literature review I have looked at a number of books and websites that I feel would help me in findings definitions for all usability features. I also looked at what applications use Virtual Reality, Human Computer Interaction and Graphical User Interface.
(http://searchcio-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 will have a feeling of being able to enter a virtual world. Most 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, office work 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/virtualrealityt.htm)
So with having the brilliant feature of being submersed into an alternative world, there can also be downsides as well. For example I would say that gaming would be one of the most popular virtual realities, and in the news you also here about how games are taking over children’s life’s, and it is contributed to make kids obese. This is true, but if used in the correct manner 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 made 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 quote I feel was found on (http://searchwindevelopment.techtarget.com/sDefinition/0,,sid8_gci213989,00.html). “A GUI is a graphical (rather than purely textual) user interface to a computer. As you read this, you are looking at the GUI”.
I love this quote because it’s 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...
